What is the reason why the electric car is out of power?

Pure electric vehicles.

The reason for the lack of power may be a loose plug in the battery bank or a disconnected internal connection line of the battery, a short circuit in the line, or a fuse.

Burning, the power-off switch on the car is not turned on, etc., will basically cause the battery to run out of power, or it will be used for too long, resulting in the aging of the battery. As far as the small battery of pure electric vehicles is concerned, there will be more or less the phenomenon of small battery power loss, which can be said to be a common problem. Under normal circumstances, the service life of the battery is 1 to 5 years or even longer, which has a lot to do with the situation of the vehicle.

For the small battery of the electric car, when the door is unlocked and the car is energized, as long as you start the vehicle or turn on the power switch, at this time, all the electrical equipment of the whole car is powered by the small battery, and the power battery is kept off.

There are several reasons why the electric vehicle is out of power, whether there is a problem with the high-voltage interlock, or there is a problem with the small battery, and there is a problem with our high-voltage system, there will be this phenomenon of no power in the whole vehicle.

If the electric vehicle is out of power, it is necessary to consider checking from the source.

First of all, use a multimeter to test the "battery" to see if the power is insufficient.

The second is to check for circuit faults, or zero, live wire disconnection problems, and possibly fuse blown faults.

The above fault judgment can basically rule out the problem of electric vehicles not supplying power.

Maybe you forgot to turn off the lights or run out of electricity; There is no charging; The battery is broken, etc.

If there is no electricity in the whole vehicle. The first thing you should do is check to see if the battery is faulty.

The common reasons for a sudden loss of power in the car are:

1. This situation occurs in most vehicles due to the low battery powerThe life of the battery is generally about 2 to 3 years, and its life is mainly related to the driving conditions, road conditions, and driving habits.

You need to drive out regularly to run the highway or to charge with an external device on a regular basis. In this case, you need to contact the rescue to take the power or replace the battery.

2. The main power supply line and control part of the vehicle are faulty, e.g. open lines, damaged control units, etc. In this case, the cause of the fault can only be found through the maintenance organization to check the fault status of the vehicle's electrical system.

About the charging time for the first charge.

Because the battery of the battery car has not been used when it leaves the factory, it has not experienced charging and discharging, so it is necessary to ensure the normal operation of the battery. Under normal circumstances, the charging time is about 5-6 hours, so that the battery can be fully charged, and then the use can be slightly longer. Charging during the day allows you to better control the time.

After the battery is used for half a year, it is recommended to charge the battery once a month, and then charge the electric vehicle battery after deep discharge, and the time is controlled at 12 hours. This will be of great benefit to the power recovery of the EV battery.

Answer the reasons why the electric car is out of power: 1. The fuse wire tube burns out; 2. The power lock is broken; 3. Poor contact between battery contacts or plugs; 4. The battery is damaged; 5. The battery line is broken by virtual welding. How to troubleshoot it:

Use the voltage block of the multimeter to detect the output voltage of the battery, if there is no voltage, check whether the fuse wire tube and the fuse wire holder, the battery, and the battery connection line are open. If the voltage at the output end of the battery is normal, check the voltage at the input end of the power supply of the controller, and if there is no voltage, check whether the electric door lock and cable are disconnected or poorly plugged. Electric vehicle refers to a car that uses electric energy as a power source and is driven by an electric motor, which belongs to new energy vehicles, including:

Battery electric vehicles (BEVs), hybrid electric vehicles (HEVs) and fuel cell electric vehicles (FCEVs).

The second is that the battery is broken (there is virtual electricity, so it can be turned on).

The third is that the brakes are not returned.

Fourth, the controller is burned out by water.

Fifth, the rotor fails. If the whole car is out of power, it is possible that the motor current is too large and causes it to trip, and the power supply can be restored by opening the circuit breaker under the base.

I'm glad to answer for you and hope it helps.

Hello, glad to answer your questions. If the whole car suddenly loses power, it is estimated that the controller fuse is burned, or the controller is broken. If the car can walk, but there is no power at 12V, it is the converter fuse or the converter is broken.

If you are walking, there is a sudden loss of power, which should be the above situation. If not, please check whether your battery cable is disconnected and whether there is any problem with the main switch of the electric vehicle.

1.The first thing may be that the power cord of the battery is in poor contact.

2.Check quickly, maybe there are really high-power power-consuming appliances in use, and it is very dangerous if there is a short circuit. And the driver didn't know that the generator was completely indiscernible after the car was started.

3.Check the battery fluid, check the positive and negative joints of the battery, if there is no problem, you will know after two days of full charge. Generally, the Liwei battery has a life span of more than 2 years, and the battery is best to be replaced once every 2 and a half years, at that time, there is no power to play, check that the battery liquid is almost dry, and it has been damaged, if it is well maintained, the battery is no problem for three years, and the battery of Liwei is Hitachi.

You first see if the fuse is good.

Check the electric door lock.

Converter relays.

Or the main circuit.

Possible causes of failure:

1. The fuse wire tube is burned out.

2. The power lock is broken;

3. Poor contact between battery contacts or plugs;

4. The battery is damaged;

5. The battery line is broken by virtual welding.

Troubleshooting: Use the voltage block of the multimeter to detect the output voltage of the battery, if there is no voltage, check whether the fuse wire tube and the fuse wire holder, the battery and the battery connection line are broken, if the voltage at the output end of the battery is normal, the voltage at the input end of the power supply of the controller should be checked, if there is no voltage, check whether the electric door lock and cable are broken and poorly plugged.

If it is a problem with the battery itself, it can be repaired and required for after-sales during the warranty period.

Reasons and solutions for electric vehicles to run out of power:

1. Battery failure.

Cause of failure: common problems include broken battery wire, loose battery line, oxidation and virtual connection; The battery is broken, the voltage is too low, and the power is insufficient; Power switches, such as air switch tripping, electric door lock failure, fuse problems, etc., will cause the vehicle to run out of power.

Solution: If the power supply is faulty due to the battery line, you can tighten the loose place of the battery, and if the wire is broken, it needs to be welded. And if the battery is damaged, you can only choose to replace it.

In addition, if it is a power failure caused by the failure of the electric door lock, fuse, etc., it is good to choose to replace it.

2. Motor failure.

Cause of failure: The main reason for motor failure is that the motor hall element is broken or the motor bearing is damaged, and the motor hall damage is generally manifested as the electric vehicle does not go, the start is weak, shaky, noisy, and pushes it with the foot before leaving. The bad motor bearing is generally manifested as the motor humming, loud sound, and if it is serious, the motor is stuck and the vehicle is out of power.

Solution: If the motor fails due to bad hall or bad motor bearing, you can only choose to replace the new motor directly.

3. Controller failure.

Cause of failure: The most typical is that the pusher motor has resistance, disconnects from the controller, and the resistance disappears, basically you can judge that the controller is damaged. In addition, it will also show that the electric vehicle is slow, shaky, weak, and unresponsive when driving.

Solution: Due to the importance of the controller, it is generally not recommended to repair it, because the repaired controller will not last long, so it is recommended to replace it directly.

4. Brake power failure.

Cause of failure: It is mainly manifested as a bad brake power-off switch, no return to the brake, and an open circuit in the brake power-off line.

Solution: If the power failure caused by the brake power failure switch is broken, it can be solved by grinding the contacts and adjusting the shrapnel. And if the brake does not return to the car and does not go caused by the power failure, the brake pads or brake assembly can be replaced.

If there is a power failure caused by an open circuit in the brake power-off line, you can choose to replace it with a new one.

If the electric car is out of battery and you need to call a tow truck to tow it home, you can also call a mobile charger to charge it. With the encouragement of national policies, many consumers will buy pure electric cars, which is the development trend of future automobiles. There are no unwanted noise and exhaust emissions when driving a pure electric vehicle.

There is no unnecessary noise and jitter when the motor is running, so it is purely electric.

There is no unnecessary noise and jitter when the motor is running, so the pure electric vehicle is quieter when driving.

Pure electric vehicles also have their own disadvantages, that is, short mileage, slow charging speed, inconvenient charging, high battery replacement cost, and the battery will not cause environmental pollution.

The battery performance of pure electric vehicles will decline with the increase of charging and discharging, and consumers need to replace the battery for electric vehicles.

The cost of replacing the battery is relatively high, and if the replaced waste battery** is improper, it will cause serious pollution to the environment.

But the battery electric car ran out of battery and could not be fully charged after a few minutes at the charging station.

And the range of a pure electric vehicle will be affected by many factors. When BEVs need to be air-conditioned in winter and summer, their range decreases. When the outdoor temperature is low in winter, the battery performance of pure electric vehicles will also be affected to a certain extent, which will also lead to a decrease in range.

How to charge an electric car building.

It is inconvenient to charge a building. You can charge at the nearest charging station. Generally, parking spaces have charging ports, and you can also use charging ports, but this charging method is relatively slow.

Since pure electric new energy vehicles are powered by lithium batteries and the vehicle needs to be recharged repeatedly, vehicle charging is more important. Many car owners will consider pulling the wire to charge, which is very dangerous, and the general property does not allow this, so it is not feasible to pull the wire to charge.

With the popularity of new energy vehicles, charging stations for electric vehicles have become very important. China attaches great importance to the charging stations of new energy vehicles, so charging stations are also very popular in some residential areas.

In general, there are charging sockets in the underground garage and electric vehicle shed, which is mainly convenient for charging electric vehicles. With the popularity of new energy vehicles, new energy vehicles can also be temporarily parked in the charging shed for charging. If there is no parking space, it is recommended that the vehicle be driven to the charging station to charge.

Advantages of electric vehicles: the technology is relatively mature, and it can be charged wherever there is a power supply.

Disadvantages of electric vehicles: the battery stores too little energy per unit weight, the number of charging stations is small, and charging is inconvenient.

What to do if the electric car dies in 2019

If the electric car is out of battery and needs to be called a tow truck to tow it home, you can also call a mobile charging vehicle to charge it.

When the new energy vehicle is out of power, first turn on the double flashing lights and place the triangle signs, after all, on the driving road, the situation is very many, and the double flashing lights and signs can remind the rear of the car. Now the tram has a backup power supply, the conventional way to open the locomotive roof cover in front of the car, there is a switch in it, after opening, you can use the backup power supply, generally the standby power supply can travel about 20-30 kilometers after use.

Compared with fuel vehicles, the mechanical part of pure electric vehicles is relatively simpler, the power battery pack can store the electricity, and then output electricity to the motor to generate power to drive the vehicle.

Resolution

In fact, pure electric vehicles are also equipped with gearboxes, but their gearboxes cannot change different gear ratios like fuel vehicles, that is to say, the gearbox of pure electric vehicles is a fixed gear ratio structure. Pure electric vehicles are directly driven by electric motors, so some car owners think that when the new energy vehicle is out of power, they can use the trailer to make the vehicle drive, and in turn charge the power battery.

In principle, electricity and magnetism can be exchanged and converted, but if you want to charge the power battery by dragging the pure electric vehicle, it is not recommended to do so, because the current generated by the passively rotating motor may damage the motor. The dashboard of the new energy vehicle will remind the remaining power and the mileage that can be exercised, as the driver should naturally pay more attention to the number displayed to ensure that the power battery can be charged.
