Three months ago, she accidentally gone home, leaving the light of the cabin light in the car if a car had no needed after five hours, it would definitely put his battery to zero. Then he decided to take on the implementation of the elimination of this Japanese jam, and for one turn off I-STOP, the more the best of the solution of these problems chose a simple timer known to many cells.
The integral performance of this timer exists more than thirty years, this is NE555N and its Russian analogue of the KR1006VI. The cost of this chip stores varies from 30p to 50 rubles, a little of this permissible current to output the chip is allowed to 200mA, which allows you to drive directly almost any small-sized relay to 12V. A fully assembled timer consists of all of the seven parts, you should only choose their nominations, collect, and check the operation of the device. There is one feature of the NE555 chips and the KR1006VI with their soldering, each subjected to the soldering output is to hold a tweezers, or another heat sink, they are very afraid of overheating.

According to the shown scheme, it is clear that everything is very simple. The course of the microfrace condenser is 22, while the response resistor, to obtain the time of operation of the relay 3-6sek, is 120-160 hours. In my version there is a 220k potentiometer.
As a collected form, there was a board with dimensions of 34.5x23mm. I completed all installation on a piece of squeezing in my trash, a batch fee. The jumpers between the details performed with a thin mounting wire. At the dummy board, it was collectable because I didn't want to bother with etching fees.

And this is the already assembled push button block with the outgoing wires of power 12V, they need to be connected to the fuse block (in the cabin under the driver's left knee) to the ACC power circuit, preferably through the fuse 1a. Little this, under the button block there is a blank pocket under the standard navigation, in it I installed the keyboard microwave, which turns off the power on the timer. This is in case you need to initialize, or in the summer it will want that I-STOP will begin to fulfill its duties.
The principle of operation of the whole system is as follows: we turn on the ignition, the power of 12V arrives on the timer, turns on the K1 relay and the contacts of the i-STOP buttons are closed by its contacts, the charging current starts to flow through the R1C1. As soon as the C1 capacitor charges to the power supply voltage, the Q1 will turn off and the I-STOP buttons will open, but during the time the relay contacts were closed, the i-STOP system will already turn off, making two beeps. In my version, the relays are closed with 5-6 seconds. In fact, we bring the function of pressing the i-Stop button to the timer with its executive relay, without caring for it to turn off each time you start the engine.
What is good, in my opinion this option, the fact that it does not require cardinal changes in the car scheme, at any time it is possible to return to the standard operation of the system, and does not require large financial investments, taking into account the fact that most of the details I have attended and I had to To buy only a relay for a 50r and chip for 35P costs are minimal. If you count all the details then in 200r you can meet.
P.S. I want to note, I am not a steep electrical engineer, rather this is a hobby remaining from the younger years, so I do not pretend, in this case, to the truth in the last instance, the more I have not suggested anything new. If, on the basis of my post, people will have more recent and intelligent ideas, I will only be happy.
And the last, if you decide to put my offer on the I-STOP disconnection, it will be your decision and for its result you are full of responsibility.
P. S. 2 must add a S1 switch from the circuit seized, its installation is of course desirable for a quick condensate discharge when the timer is turned off, but for this then it is necessary to burn a whole garden, naturally with an increase in the number of parts and of course dimensions.
The Japanese crossover is equipped with a large number of modern electronics, the serviceable operation of which largely depends on the quality and capacity of the battery. The right choice and installation of the battery will help to avoid trouble on the road associated with the failure of the main nodes. The Specificity of the battery Mazda CX-5 - I-STOP system. In this article, we will tell you all about the features of the work of the battery, let us give advice on the choice, share the instructions for self-replacement and insertion of the battery.
How battery works
The original Mazda CX-5 battery is installed by the manufacturer. It is responsible for the performance of all the electrical components of the car. If the battery comes into a malfunction, it is impossible to start the machine. Let's deal with what the principle of action of this small but very important component is.
The functioning of the battery is fully constructed on the transformation of chemical energy into electrical and vice versa. In addition, the device provides constant current strength, and precisely thanks to stabilization of voltage, the motor can normally work normally.
The battery is equipped with two poles - positive and negative. The battery terminals are connected to the car, due to which the main mechanisms can perform their tasks to be sureless. The components depending on the additional source of energy include:
- engine;
- audio system;
- air conditioning;
- optics;
- wipers, etc.
The principle of operation of the battery lies in the features of its structure. Often, the part consists of 6 cells, in each of which 2 electrodes made of metal plates are placed. This galvanic element provides a car power.
Akb work in i-Stop mode
The battery for the car Mazda CX-5 is subjected to huge loads due to the operation of the i-STOP system. This is due to the constant shutdown and starting the engine during the auto stop. Thus, the owner receives a reduced fuel consumption by increasing the wear of the battery.
The highest current cost is carried out at the time of launching the power unit. In the future, the partial discharge of the ACB is compensated by the procedure from the generator. When driving around the track, the crossover battery is charged in standard authored, and each stop in the city feature activates the i-STOP (the generator does not work).
The action of the I-STOP depends on the degree of charge. With SOC below 65%, the system refuses to function.
Procedure for disconnection, connection and replacement of the Mazda CX-5
The need to replace the battery on the Mazda CX-5 appears when the SOC charge level drops below 25%. With this indicator, the recovery is already becoming impossible. Conduct installation, connect or remove the Mazda CX-5 battery itself even inexperienced auto owner.
To dismantle the old battery you need:
- Disable current sensor from a negative terminal to deraid onboard computer.
- Remove all terminals.
- Remove the fixing bar.
Installing the battery is carried out in reverse order. The next step is the recharge and initialization of the battery.
Registration and initialization
To work properly, you need to know how to register the Mazda CX-5 battery. The procedure varies depending on the presence of a liquid crystal screen. So, the owners of the car without TFT LCD need to follow the instructions:
- turn off the engine;
- translate the PPC lever to the N;
- press and hold the brake pedal, performing further actions;
- long-term pressing of gas activate the Akb indicator;
- press and release the accelerator three times to deactivate the light bulb;
- release brake.
For crossover with TFT LCD scheme, this is:
- close the doors;
- turn the ignition to the ON position without launch;
- info switch Delete Warning Message;
- install the gearbox lever into the neutral position;
- hold the brake pedal, performing the following actions;
- turn on the accelerator for 5 seconds, wait for the indicator activation;
- 3 times press and release the gas (while the beacon should go out).
Also, after connecting a new battery and its registration, you must pass the Mazda CX-5 battery initialization, since the settings are reset when the terminals are disconnected. The algorithm is the following:
- run and warm up the motor;
- hold and hold the i-STOP for 10 seconds;
- when the hood is closed, turn the steering wheel from one extreme position to another;
- motor drowned.
Check if the initialization passed by pressing the i-STOP button. If the green light caught fire, it means that the AKB came to the work of all systems.
How to choose a battery for Mazda CX-5
The Japanese brand recommends installing the original Mazda CX-5 battery. This is due to the i-STOP technology, which builds the operation of the power unit of the machine. Consult about the model can be in authorized service centers. The first-generation crossover was equipped with a Panasonic Q-85 Akb, but today the range has grown significantly, and such well-known brands have come to the market as: Exide, Bosch and many others.
To understand what battery is on Mazda CX-5, you need to carefully examine the label from the manufacturer. When choosing, it is important to pay attention to the overall dimensions, capacitance and starting current. The battery capacity should be characterized by a range of 40-70 A / h, the rated voltage indicator is 12 B, the starting current of 300-700 A. It should also be carefully referring to the polarity of the device, the coincidence of the terminals. As for dimensional characteristics, a small subcarrane space requires them to withstand them especially clearly. Engine owners 2.0 buy AKB 202x230x172 mm (VHDHSH), for 2.2 liters are chosen 202x255x172 mm. The cost of the new CX-5 battery starts from 6500 rubles.
Battery marking, reviews
In order not to be confused from the abundance of the range and purchase a suitable item, it is important to be able to read the marking. The manufacturer inflicts code on the product, decrypting which you can learn the main technical characteristics of the product.
What indicate the markings of the Japanese brand AKB (JIS Standardization):
- capacity of the Mazda CX-5 battery;
- battery width, mm;
- battery length, cm;
- location of terminals, polarity (L or R).
According to the reviews of the car owners, it was possible to find out that brands Varta and Bosch were most popular on the territory of Russia. These trademarks offer high-quality products at a competitive price. Good demand is noted on the Bosch S4 02 model (it has an indicator of the start current - 540 A and a capacity of 640 AH). It should be understood that the car with a large number of electronics requires the installation of a high capacity battery.
Possible troubleshooting
Like any detail, the battery sooner or later comes in disrepair. If the machine does not start (especially in frosty weather), it is worth checking the performance of the AKB. Possible problems:
- Battery edema. In case of blinking the case, the device must be replaced urgently. The cause of deformation can be increased temperature of operation.
- Unpleasant sulfur smell. This is a battery leak. The breakdown is also accompanied by the appearance of rust on terminals.
- Low fluid. If the amount of fluid dropped below the lead plates, it should be done on topics or replace the battery.
To the battery, and with it, all the electronics functioned properly, you need to be diagnosed. Write a breakdown can: a violation of the temperature regime during operation, insufficient charging, low-quality electrolyte and much more.
Outcome
The battery operation ensures the start of the engine and the power supply of all electronic systems. To extend the battery life, it is important to carry it on time and adhere to operating modes. If the need for replacement has already arisen, it is not necessary to seek help at a hundred. Installation, registration and initialization can even conduct an inexperienced routeman.
What should be fuel consumption in a 150-strong two-liter engine that disperses two-ton crossover Mazda CX-5? It would seem - not small. But in fact, thanks to the intellectual SMART system i-Stop., turning off the engine, even with short stops, work at idle is minimized. The result - the Motor CX-5 consumes about one and a half times less than fuel than its "classmates" (Nissan X-Trail, Tiguan, Audi Q3, Q5). However, the frequent stops / start-ups of the engine presented special requirements for the power supply of the car.
Effect of I-STOP system on Mazda CX 5
It is known that the maximum current battery gives when the engine is started. Next, its partial discharge is compensated by recharging from the generator. If after the long-lasting trip on the highway follows, then the CX-5 Mazda battery is charged in a common source for most. When driving in the urban cycle, each car stop launches the i-STOP system, and the generator work stops. On the battery for Mazda CX-5 with i-Stop, in addition to the energy source function, the power supply functions of all on-board systems of the vehicle are also superimposed by the power of the engine - audio systems, climate control systems, diagnostic systems, electrical sensors, external lighting and internal illumination, glass heating and mirrors, heated seats, etc.
Effect of the degree of charge of the battery to work the i-STOP system
Not only the i-STOP affects the battery for Mazda CX-5. There is also feedback - the work of the i-STOP depends on the degree of charge. The parameter characterizing the battery charge state is expressed as a percentage and called State of Charge. or simply SOC. For the correct operation of the i-STOP system, the SOC indicator should be above 85%. And at SOC, less than 68.4% I-STOP stops working at all.
Smart Charging Akb CX-5
Fully compensate for the loss of electrical energy when operating the i-STOP system in the urban cycle is impossible, but Mazda engineers worked out that even with frequent shutdown / engine launch battery Mazda CX-5 2.0 Standard equipment received maximum recharging. It was achieved by the introduction of the so-called intelligent charging system (smart charging).
When slowing the car caused by a decrease in the fuel supply to the engine cylinders or braking a car (by braking or by braking by engine), the current sensor automatically increases the generator voltage, thereby allowing additional electrical energy to charge the battery. In addition, smart smart charging allows you to use the kinetic energy of the car, reducing the load on the generator, which also has a positive effect on fuel economy. Of course, the "fast charging" of high currents is not the best way to preserve the long-term operation of any power source, but so far nothing better in this area is invented.
IMPORTANT! Use the "Quick Charging" mode when charging using the charger is not allowed. Ignoring this comment can lead to the failure of the I-STOP system.
Charging the battery Mazda CX 5 at home
The degree of discharge intensity depends on many factors. These include: enabling the security alarm, opening / closing the doors / hood, position of the automatic transmission arm (to minimize leaks it is recommended to leave an uncutable car with the automatic transmission lever installed in the "P" position) and even finding a car in the cabin or near it ("Washing Map"). Therefore, the overwhelming majority of the owners of Mazda CX-5 sooner or later will require additional charging of the battery of their cars. Make it at home is quite realistic with the help of a special charger. MAZDA CX-5 MAZDA CX-5 manual recommends this procedure every 2-3 weeks.
Consider how to charge the battery on the Mazda CX 5.
To begin, it is necessary to establish the fact of the need for charging the battery, i.e. Rate SOC. This is done by measuring the density of the electrolyte using the hydrometer. At the same time, it should be remembered for the effect on this ambient temperature indicator. Match the density of the electrolyte at a given air temperature with the SOC indicator on tables that contain special reference books both printed and online.
For example, at ambient temperature, 20 degrees SOC \u003d 100% will correspond to the electrolyte density of 1.280 g / cm cu., SOC \u003d 85% - 1.262 g / cm cu., 65% - 1.234 g / cm cu., Respectively. At a lower ambient temperature, the electrolyte density corresponding to a specific SOC level will be higher at a higher temperature below. To have a complete table of compliance with the electrolyte density, SOC level at different temperatures is optional. It is enough to remember the formula of bringing:
The density of the electrolyte (at T \u003d 20 o C) \u003d the measured value of the density + (the actual temperature of OS - 20) x 0.0007.
Before charging the Mazda Cx 5 battery, mark the most discharged jar. Based on the electrolyte density in it, the battery charge time is selected on the tables. For example, the density of more than 1.24 says that the charge time is 180 minutes, and the density of 1.17 will require for a full charge for 360 minutes. It follows a constant current of 10 amps, checking and adjusting (if necessary) current strength every 60 minutes.
Evaluation of SOC (electrolyte density) is carried out 6-48 hours after charging. If the electrolyte density in one of the cans is less than 1.25, then you should think about buying a new battery.
In the autumn-winter period, the number of electricity consumers is significantly increasing. Additional loads are given by the above-mentioned climate control, heat heating and mirrors, heated seats, as a result of which the discharge occurs much faster than in the summer. At one fine moment, the car may simply get started. Some car enthusiasts in this situation work on the protection - turn off I-STOP. About saving fuel in this situation can be forgotten. Engine Auto and power supply Mazda CX 5 work in the same mode as hundreds of other car models. Option Two - to purchase and always carry with you the external source of electricity - an autonomous commissioning device. This will allow, if necessary, make an emergency launch of a car motor.
The modern autonomous commissioning device (booster) does not take up much space. It can be used if necessary for the launch of the OBS and to replenish the charge of the standard energy source. After starting the engine, the charge's own booster can be filled immediately by connecting it to the electric network of the car through the cigarette lighter connector.
Replacing the battery Mazda CX-5
Monitor the battery level is very important. When SOC drops below 25% (electrolyte density before charging below 1.17), the battery recovery will be very problematic. In the plates, irreversible changes occur, which will not allow you to recruit and detect the charge that is necessary for stable operation of the i-STOP system.
How to change the battery on Mazda CX 5
The procedure for replacing the ACB on the Mazda 5 is very simple. First of all, you should remove the old battery:
1. Disconnect the current sensor from the minus terminal. By this, we de-energize the on-board computer, not allowing the possible passing of an erroneous engine control signal.
2. Remove the minus terminal.
3. Remove the positive terminal.
4. Remove the fixing bar.
Installing a new Mazda CX 5 battery follows 1 minute after removing the old one. For this small temporary gap from the memory of the PCM block (Powertrain Control Module - it is the "brains") information about the state of the old battery will be deleted. Installing a new battery is made in the sequence, reverse removal.
After installing a new battery, it must be "prescribed" in the system:
1. When the engine is turned off, set the engine start switch to ON.
2. Install the automatic transmission lever to the "Neutral" position.
3. When the brake pedal is pressed:
- press and hold at least 5 seconds gas pedal. Should start flashing the battery charge akb and the main warning signaling device;
- press and let go of the gas pedal. Account signaling device and the main warning signaling device should go out.
If the car Mazda CX-5 is equipped with an LCD display of the device's combination, before installing the engine start switch to ON, you must close all the doors, after installation - wait for the warning message on the display, then remove it with the Info switch located on the steering wheel.
To check how correctly the Mazda CX-5 battery is passed, it is necessary to turn on the ignition, then press and hold 10 seconds the I-STOP switch. A flashing green indicator will mean a successful passage of the initialization procedure of the ACB. A flashing yellow signaling device means an underwear or recharge battery. A constantly burning yellow alarm means that the battery initialization in the system is not fulfilled, it is required to repeat it.
For the correct initialization of the AKB of its SOC must be more than 75%.
What battery can be put on Mazda CX-5
Given the specifics of the I-STOP system, the manufacturer strongly recommends using the original Mazda CX-5 battery, which can be clarified by the Mazda catalogs. In addition, comprehensive information on which battery to put Mazda CX-5 can be obtained from specialists from authorized service centers Mazda. Initially, the conveyor Mazda CX-5 crossover was completed with 65-ampered batteries GS Yuasa. Q-85 . Today the line of permissible batteries expanded significantly. To find out which battery is in Mazda CX 5, you can, having studied the sticker on its case. When choosing a battery, different from the one that the car was completed on the conveyor, take into account not only the capacity and starting current (for models with a two-liter engine - a starting current of 540 a * h, for engine models with a volume of 2.2 liters - 640 a * h), but and type ( AGM / EFB.).
It is very important to pay attention to the overall dimensions. Extremely dense layout of the boobspace obliges to withstand them especially carefully. The owners of a two-liter motor must select Akb corresponding to the size of 202 x 230 x 172 mm (height x Length x Width), the model of 2.2 liters will request a longer niche - 202 x 255 x 172 mm - battery marking
Mazda CX-5 in all configurations has an i-STOP system (analog Start / Stop Engine), what is it needed for? After warming up the engine, the i-STOP system automatically shuffles it when the car stops on the traffic light or in the transport "plug" and then automatically restart the engine to continue movement. This system is designed to increase the fuel efficiency, reduce the exhaust gas emissions, as well as reduce the noise level in the period until the engine works.
Stop and restart function (cars with manual transmission)
1. Press the brake pedal, then remove the clutch pedal and stop the car completely.
2. After the car stops holding the clutch pedal in the squeezed position, move the gear shift lever to the neutral position. After the clutch pedal is released, the I-STOP system activation indicator will turn on (green), and the engine will automatically stop.
3. In order to start the engine again, unlock the clutch pedal (while the green indicator of the i-STOP system will go out).
Stop and restart function (automobiles with automatic transmission)
1. The I-STOP system is shuffling the engine, when the driver presses the brake pedal while driving, and the car stops (except for situations where the car moves with reverse). During operation of the i-STOP system, the light indicator of its activation (green) is included.
2. After the driver releases the brake pedal when the automatic transmission selector lever is in the D / M position (but not in the fixed transmission position position), the engine will automatically restart, and the I-STOP activation indicator (green) will go out . If the selector lever of the automatic gearbox is in position n or p, the engine restart will not occur even after the brake pedal is released. The engine will start after re-pressing brake pedal 
Why i-Stop does not work, the engine does not stop (not joined)
Next, excerpts from the Mazda CX-5 user manual:
To ensure the safe and comfortable operation of the vehicle, the i-STOP system controls the stop and automatic engine restart function, which is constantly monitored by events that are not controlled by the car, in particular the conditions of the surrounding environment inside and outside the car, as well as the working condition of the car systems. The engine automatically stops when the conditions listed below are fulfilled:
- The engine was launched, and the car was in motion for a certain period of time. Regardless of the duration of the engine, the I-STOP system will not function if the car has not started movement. In addition, after the movement of the car for a certain period of time and the subsequent stops, the i-STOP system will turn on only one cycle (automatic stop and restart of the engine) during the vehicle stop.

How the I-STOP CX-5 system works
(YouTube) XQCF8IUWEK0 (/ YouTube)
On the Mazda CX-5 cars of the last years, the manufacturer is installed by the i-STOP system. Many are interested in what it is, does the system benefit from the car owner, and is it possible to turn it off?
What is i-Stop
The I-STOP system (ay-stop) of the Mazdacx-5 car is the function of intelligent stop and restarting of the engine, the company's branded development of Mazda. If you briefly describe the principle of operation of the system, it is as follows.
The car engine is automatically disconnected in traffic jams, on traffic lights, when the car stops, and then it is independently restarted when the driver wants to continue the movement.
In more detail, the operation logic is set out in the table.

The engine will be stopped automatically when performing all conditions, depending on the presence of climate control and type of gearbox.
Advantages and disadvantages of the system
The main purpose of the I-STOP system is fuel economy, reduced noise levels and harmful emissions into the environment. In addition, the i-stop adjusts the generator power (intelligent charging system), because the largest consumption of electricity is to start the engine, and the charge loss must be quickly fill.
At the same time, ah-stop solves the problem that he himself also creates: it is repeatedly repetition of a start-stop cycle that increases the load on the battery, which also takes on the power of all the car systems when stopping the engine.
You must not recognize that the multiple repetition of startup and stop the car significantly reduces the engine resource.
It is not as critical when driving on the highway, where the car most of the path moves continuously with approximately constant speed. But, as practice shows, most Mazda CX-5 owners use a vehicle in an urban environment where the stop is replaced by the resumption of movement with sufficient regularity. And when inserted into the tube- "Tying", the engine can be afraid, to start several dozen times in a row, which will not add "health" at all.
In addition, many Mazda CX-5 users are unhappy with the I-STOP system for purely psychological reasons. Not everyone soul "strongly smart" modern cars. Many drivers of the old hardening wish to fully control the aspects of the work of their "iron horse".
How to turn off forever
One way or another, many are wondering how to disable I-STOP forever. The manufacturer did not provide such an opportunity, so home-grown "couulins" took for business.
On the forums of car owners, various ways are considered. The easiest - disabling the battery charge sensor. But at the same time, the driver himself remains without information about the charge of the battery, which for obvious reasons is unacceptable.
Various options for changing electronic circuits require specific skills and skills. We propose to solve the problem programmatically. To do this, you will need:
- notebook;
- adapter ELM327;
- program
The essence of the method is as follows. The SSU software module has the difference between the Mazda CX-5 car models with the Ai-Stop system and without it:
View of the module SSU. at the car with the system of ae-stop.
View of the SSU module at the car without ai-stop system.
Task - change the module by changing the specified values.
- We connect the laptop to the car on-board computer through the adapter and run the Forscan program.
- We find in the menu item specified in the figure.

Before making any changes, be sure to make a backup module!- We change the values \u200b\u200bof the extreme left cells in the two top rows.
Before changes.
After change.
That's all! You can turn off the laptop, turn off and enable the ignition of the car. After initializing the Mazda CX-5 system is ready to use!
The advantage of this method is that no physical changes are made to the car device, and all software action is completely reversible.
As far as the whole is useful to the ai-stop system - the subject of discussions. Many believe that the developers sacrificed the engine's resource for the sake of imaginary fuel consumption and fashionable ecologism. In any case, whether those or other features of a personal car are your choice.
