How to solve the problem that the electric car does not catch fire?

1. Take the wire: This is a necessary item for the car to take the electricity, do not take two wires to make do, because the instantaneous current of the vehicle at the start can reach 200-600A, and the diesel car even reaches 1000A, if it is calculated, 10 square copper wires can ensure the smooth and safe start, so the car battery.

The cable must be bought of the right brand, the quality of the first, do not try to be cheap. This is one of the must-have items in the car, once the battery is out of power, you can take it out and use it, and you can also help others when you don't use it.

2. Emergency power supply: This is a new type of power bank like a power bank.

The same thing, there are two kinds of lead-acid and polymer lithium batteries, which can help start the vehicle with a loss of electricity, and can also have multi-functional products for lighting, charging mobile phones and inflating cars with inflatable pumps. And it is generally portable, very lightweight, if you have it, you don't have to ask others for help. Be sure to charge it in time after use and keep it full of power to deal with emergencies.

3. Positive, first connect the positive: first turn off all the electrical equipment on the car, make the key in the OFF position, open the cabin cover to find the battery, there are positive and negative poles written on the battery, generally the red "+" sign is the positive pole, and there are generally two wires, at this time, take out the red one, open the battery cover, pinch the clamp on the head to clamp firmly the positive pole of the battery of the electric car, and the clamp at the other end to clamp the positive pole of the battery of the rescue vehicle. Be sure to connect the positive electrode first, then the negative electrode, do not reverse the order, and do not use the battery clamp to touch anywhere except the battery pile head.

4. Negative connection, negative connection: After the red positive electrode is connected, take out another wire, first clamp the negative pole of the tram battery, the negative electrode is generally black "—" number, and then pinch the other end of the clip, from beginning to end the clip do not touch other places, to clamp the negative pole of the rescue vehicle battery, when the connection will pop out of the electric spark, please don't be afraid, this also shows that you are right. The reason why the negative electrode is not connected first is because the whole vehicle is basically a negative electrode (that is, commonly known as "tie iron"), if the negative electrode is connected first, when connecting the positive electrode, the clip will cause a short circuit and burn the parts on the car when it touches any conductive place in the body.

5. After starting the vehicle, first remove the negative, and then dismantle the positive: after the battery is connected, the rescue vehicle will first ignite and charge the battery, and then the no tram enters the vehicle to open the key, at this time the instrument light will be lit smoothly, and then try to ignite (not more than 5 seconds), if it fails to start smoothly, step on the accelerator of the rescue vehicle, and the speed is kept at about 2500 rpm, and then the tram is ignited again, if the starter is no problem, the car has oil in the case of general can be started smoothly, after the non-electric vehicle starts, Remove the negative clamp first, then remove the positive clamp, for the same reason as why the negative pole is followed by the fourth one.

The positive and negative poles of the battery must not be reversed, and the order of assembly and disassembly should be strictly in accordance with the order of first connecting the positive and then the negative, and the first dismantling and then the positive.

1. Regarding the problem of idle speed, sometimes it is not ignited, because of the low idle speed, and it is OK to look at the number of mai expression pointers to one grid or more points in normal summer, and adjust it to more than one and a half or less than two in winter.

2. The problem of the spark plug, you can replace one, sometimes the oil will drown the mouth, see if the spark plug head has oil, wet or not, and it will not catch fire.

3. If the carburetor is faulty, it is necessary to clean the carburetor after a long time.

4. The weather is cold in winter, so it is easy to appear that it is not easy to catch fire. The climate in the south is warm, and there will be no failure to catch fire, except for the failure of the motorcycle itself. At the beginning of spring in the Northeast, or the beginning of autumn is about to enter the winter season, the temperature is cool and below 0 degrees Celsius in the morning, and the engine oil is condensed, resulting in no fire.

4.A battery pack is composed of multiple small batteries, and each small battery also has a connection line between them, if the connection line becomes loose or corroded by external forces, the contact will be poor.

At this time, if it is unloaded, the electric car seems to have electricity, but in fact, it cannot be started. Use professional testing instruments to find the poor contact area, and then change the line to repair.

5.A faulty motor hall causes the EV to have power but not start: If the EV motor hall fails, it will cause the entire EV to run blocked.

At this time, although the electric car seems to have electricity, it cannot start driving. For this kind of problem, due to the high degree of replacement of Hall technology, it needs to be pushed to a special electric vehicle store for maintenance.

6.The power cord of the controller is loose and falls off, causing the electric vehicle to have power but not start: As the brain of the electric vehicle, the controller is often the most overlooked and important accessory.

Many electric vehicle users, the electric car has power but cannot start, and a direct reason is that the power cord is loose and falling off. In order to solve the problem in this case, the user needs to check whether the red and black thick lines are loose, and if so, they can solve the problem.

The car you just bought can't catch fire, you can contact the after-sales service directly, and it is still in the range of three guarantees, if there is no problem with the brakes, then the electric car can not start and does not respond, this is the problem of the line. So at this time, we need to find a professional electric vehicle repair shop to check whether the line is normal. In this way, under their professional maintenance, the problem of unresponsiveness will be solved quickly.

First, check whether the battery power is insufficient, whether the gear is wrong, and whether the car fuel is sufficient. In addition, motor failure, or oil pump oil supply, fuel injector problems, sensor failure, etc. will also lead to failure to ignite, it is recommended to contact the maintenance personnel in time for testing.

If it is a new car, it is recommended that you also go to the place where you bought the car to communicate, and if you are really not at ease, you can ask him to change the car for you.

Electric cars have a neutral button, usually near the handlebar, you see if you touch it.

What should I do if the electric car doesn't catch fire? 1. If the battery is in poor contact, it cannot be started. Workaround:

Use professional testing instruments to find the place of poor contact and repair the changeover. 2. If the motor hall is faulty and the tram cannot start; Solution: Replace the motor Hall, which needs to be pushed to the repair shop for repair.

3. The controller is broken; Solution: Replace the controller.

To maintain the battery, first of all, for the maintenance-free battery, it is generally necessary to observe whether it is to be replaced through the circular inspection port above, which is usually blue-green when it is normal.

When it is abnormal, it will appear white or yellow, and in addition, the liquid level can be observed through the battery liquid level indicator line of the battery case. For batteries that are not maintenance-free, if they have been used for a long time, the battery should be sent to a service station for a thorough charge, and battery fluid should be added to keep the battery in good working order.

If the battery is not broken, when the battery is discharged close to running out, it must be charged for 12-18 hours. Then it can be charged for 3-5 hours. Then it can be charged for 6-8 hours.

But it's best to be undefeated for more than 24 hours. When the electric vehicle is not in use, it is generally required to be charged once every month, and it can generally be used for 1-2 hours after charging.

The failure to ignite may be due to the loss of power caused by the long-term headlights not turned off or the power loss caused by the source of distress or Wang Xin's state is the expiration of the battery life, and the battery is generally replaced in time according to the maintenance manual. In addition, the installation of xenon headlights, high-power audio, etc. are also the causes of vehicle circuit failure.

When the children's electric light shouts that the leaking motor car cannot be started, it is likely that the line has a seepage hole and poor contact. It is also possible that the motor has been damaged. You can take the electric car to the sales point and let the boss check it, and if it doesn't work, send it to the manufacturer for repair.

Electric cars do not need to be ignited. If it is not possible to walk, it may be caused by a short circuit in the internal line. You can disassemble it from the wheel core line to see if the circuit is normal.

The most common factor is that the battery of an electric vehicle loses power. The quality of the battery of this electric car is not agreeable, and generally this will be damaged.

It may be that there is a problem with the spark plug and guess, if there is a problem with the general spark plug, it is easy to produce a macro type that can not be fired, it is recommended to replace a mask.

There are many reasons why children's electric cars can't catch fire, such as breakdown, or can't be charged, and he also needs pads or batteries.

The source of disadvantage is to see whether the child's electric vehicle is recharged, or whether the battery is broken and needs to be replaced, you can go to the maintenance of the electric vehicle for inspection.

1. If the battery is in poor contact, it cannot be started. Solution: Use a professional detector chain thickener to find the place of poor contact and repair the line.

2. If the motor hall is faulty and the tram cannot start; The method of solving the balance and calling the situation: Tell the motor Hall to be replaced, and you need to push it to the repair shop for maintenance. 3. The controller is broken; Workaround:

Replace the controller.

The reason why children's electric vehicles do not catch fire may be because the ignition system of the electric car is faulty and needs to be repaired.

A child's electric car won't start because the battery is under-voltage, dead, or damaged. The 60Ah battery is powered by a 12V electric ballast boost, with a power of about 10 watts, and if the standby power of other power supply equipment is counted, the power consumption of the whole car does not exceed 30 watts. Theoretically, the radio is capable of listening continuously for 24 hours.

Solution: If the battery is out of power, you have to borrow other batteries to start or find a few people to start with the universal cart start method. If the ignition is not ignited, it may be due to the loss of power or trembling caused by the long-term headlights not turned off, etc., the battery life expires, and the battery should be replaced in time according to the maintenance manual.

Common faults of electric vehicles for children.

Remote control reception failure.

1. If the transmitter is not in power, the battery needs to be replaced (the battery should be replaced once every 4 months).

2. The receiver power supply is not connected or the wiring is poor (red, white, and black wires).

3. If the startup password fails, you need to re-check the code.

The instrument display is normal, and the motor does not rotate.

1) The cause of the failure.

Judgment of brake handle damage.

Judgment of damage to the speed control handlebar.

Motor damage judgment.

The controller is damaged.

2) Troubleshooting.

Unplug the brake lever socket (normally open brake lever). If the motor is running, it is a brake handle failure, and the brake handle should be replaced.

The 5V voltage of the turn source is normal, detect the signal voltage of the turn handle, and rotate the state infiltration turn handle, and the signal voltage should change from low to high. If there is no change in voltage and it is less than 1V, it is a handle fault or a short circuit in the handle line. If the voltage is greater than 1V and the change is normal, detect the motor Hall signal (yellow, green, blue line).

If the voltage of the three-phase Hall signal line is all 5V and the contact is good, the motor Hall is damaged, and the motor or motor Hall components should be replaced.

Detect the motor Hall signal line separately, slowly rotate the motor by hand, the voltage of each phase should change between 0 5V, if the voltage does not change, the motor Hall is damaged, and the motor or motor Hall components should be replaced. If the voltage conversion of each phase is normal and the power supply is normal, the controller is damaged and the controller is replaced.

Use a multimeter to detect the voltage of the input terminal of the power supply of the controller, the voltage should be greater than 36V (the battery is sufficient for the source to be electrified), if there is no voltage, the input line should be checked. Check the power supply voltage of the controller (the red and black wires of the turn to the hail), the normal voltage is 5 6V, if there is no 5V voltage, unplug the handle socket, and the voltage is restored to 5V, it may be a short circuit of the motor Hall element, if there is still no 5V voltage, it is a controller failure, and the controller should be replaced.

First of all, check whether there is a short circuit at the beginning of the speed control handle and the motor hall, generally it is easier to cause a short circuit in the joint after rain and moisture, so it is necessary to pay attention to the waterproof handle joint, if the controller is damaged, before replacing the new controller, you should first check whether the handle and the motor hall switch are short-circuited? Otherwise, it will cause continuous damage to the replacement controller!

Reasons why new energy vehicles can't catch fire:

1. The battery is out of power, which may be due to the loss of power caused by the headlights not being turned off for a long time.

2. Or the battery life expires, and the installation of xenon headlights, high-power audio, etc., is the cause of vehicle circuit failure.

3. The gear is wrong, when the automatic transmission car starts, the gear should be placed on the P gear or N gear.

4. Manual transmission car, if you don't step on the clutch, it will not catch fire.

5. Excessive carbon deposition in the vehicle will cause the vehicle to fail to ignite, and often run at high speed to reduce carbon deposition.

First of all, to see if the car is out of gas, no gas is naturally not on fire, many people will definitely scoff and laugh when they see this, indeed, this mistake is relatively low-level, generally no one will make this kind of mistake, but not everyone will not. If you can't ignite it because you run out of gas, you just need to find a way to refuel.

In addition, check if the battery is dead, if you use the appliance for a long time, it will cause the battery to lose power and cause it to fail to start. This happens mostly in cars that are older and have been idle for a long time.

Again, see if the gear is not adjusted well, unlike the manual transmission model, the automatic transmission model gear is not in P or N gear, and when R or D gear, it cannot be started. In addition, when the steering wheel is locked, the automatic transmission cannot be activated.

In addition, if the throttle is dirty, the cold car starts the throttle due to carbon deposition and does not have enough air to enter the starting engine, so the engine will not start, add some throttle to increase the opening of the throttle, you can start, and it is recommended to clean the throttle.

There is also if there is no antifreeze may not be able to start, some car owners add water or inferior antifreeze to the car, resulting in a particularly cold winter, resulting in the entire waterway being frozen, the engine is frozen and cracked, resulting in the car water pump can not operate, can not catch fire, and hurt other parts of the engine.

In addition, many cars now use the smart key to start with a key button, when the battery of the smart key is insufficient, the sensitivity of the smart key will be reduced, and the one-button start button of the vehicle cannot be sensed, resulting in the car not being able to get on the car. At this time, just go outside to help the smart key change the button battery, and the problem will be solved.
