On the way, the electric car suddenly turns off and there is electricity, what should I do?

Check if a part of the car is loose or damaged, and then find someone to repair your car and explain the specific situation of the tram.

In addition to the suspicion of the quality of the battery itself and the failure of the charger, the high power consumption of the electric vehicle caused by the aging of the electric vehicle motor, the poor matching of the controller, and the excessive running resistance of the electric vehicle is also the reason why the electric vehicle cannot run, and some parts can be considered to be replaced.

If the motor is running normally, the motor and the controller are good, if the motor does not rotate, the motor is bad or the controller is bad If the motor and the controller are normal and the motor does not rotate, it may be a problem with the handle and the brake handle.

Sometimes the battery line is loose and there is no power output. If the power line has an electrical output, the electricity depends on whether the brake is returned. If there is no return, the train will not start even if the car has a tram when the power is off.

It may be that the position of the gate is broken, I have often encountered such a situation before, because the brakes of the car are broken, resulting in the state of braking all the time, and the car cannot go.

You can go and measure the neck line of the motor. Whether the Hall line has an output signal. Measure whether the rotor has an output voltage of 1-5V, etc. You can turn the knob at the controller to see if it turns. You can consider replacing the parts for trial repair.

It should be something that went wrong, causing poor operation, and it is recommended to push it to the place where the car is repaired to repair it and check what is the problem.

It is necessary to see if the outside wire is disconnected, most commonly at the crutch. The bottom of the car, etc. Then see if the brakes come back to place. Because it can't return to the original position, the brake will turn on when the power is off.

Some electric taillights are broken and don't leave, which is the case with the real cars I used to ride.

If the power light is on, operate step by step from simple to difficult:

1 Repeatedly pinch-loose-pinch the brake handle to see if it returns to normal. If it returns to normal, it means that there is a problem with the brakes, which may be the sensor or the wire.

2. Disassemble the back seat of the car to see if there is a short circuit. For example, this kind of situation will occur when the wrapped plastic skin melts.

3 Disassemble the battery box and check whether the cable has any broken points. Now the pedal electric vehicle battery is at the bottom, and the screw is unscrewed, and you can see that the battery pack is connected in series with wires, and if the solder point is not soldered well, it will break off due to bumps.

4 The last thing to consider is that the controller is damaged, because the controller itself is not so easy to break.

The sudden shutdown of the electric vehicle should be manifested in the sudden power failure during riding, which is caused by a circuit problem.

Check the accessories related to the circuit, including circuit breakers (air switches), fuses, controller interfaces, and battery pack wiring, and check them one by one and repair them in time.

If there is still a problem, you can only go to the maintenance shop to check the three major parts, including the motor, controller, and battery.

It's not good to say, you have to check the circuit It may be **short-circuited and the fuse is burned out.

Turn off the power and see if the air switch jumps over to check the fuse.

Reasons for the sudden stalling of the car while driving:

1. Circuit fault;

2. Flameout caused by short circuit of low-voltage line: intermittent flameout; 3. Device failure: it can start at first, turn off after a while, and then start again, and then turn off again;

4. Oil circuit failure; The gasoline pump was damaged, the oil line was ruptured, the carburetor inlet was clogged, and the fuel tank ran out of oil.

5. There is a problem with the ignition system and the explosion-proof system for engine overheating.

When it is found that after the ignition is turned off, according to the road conditions at the time, if there is no emergency, you can slowly step on the brakes to prevent the tail light, after the speed is reduced, slowly play the direction, drive to the roadside lane, pay attention, the brake should be stepped on all the time, the power from small to large, do not step on it and then loosen, and then go to the pedal, which will lead to the only remaining vacuum is also consumed, and then step on it can not be stepped on, park the car on the side of the road, turn on the four flashing lights, place the tripod, and hit the ** rescue trailer. Hope!

Hello, dear. The reasons and solutions for the sudden shutdown of electric vehicles are as follows: 1. Caused by weak brake return spring.

The return spring plays the role of resetting, so that the brake pads are separated from the wheel, and now after the brakes are released, because the spring is not working, the brake pads and the wheel hub are not separated, the brakes are locked, and the car cannot move. Just change the tension spring. 2. If the controller is broken, it can't output current and voltage, test it with a multimeter, and replace it with the same type of controller if it is broken.

3. If the line contact is not effective, check the line. ‍

This condition is caused in two ways:

1. It is because the controller (three-phase AC inverter) is suddenly damaged due to high heatIt also makes the output of the three-phase power supply form a short circuit between the components (at least there is a short circuit between the two phases), and the motor is in a short-circuit power generation state (working in the state of energy consumption braking and braking) when it is pushed, which makes it very difficult to push.

Solution: Remove the circuit connected to the motor by the controller, so that the motor can get rid of the short circuit of the controller, so that the motor is in the working condition of no-load operation of power generation when it is implemented, so that the implementation becomes easy. Go to the repair point and replace the controller with a new one.

2. It is caused by a sudden inter-turn short circuit inside the motorAt this moment, even if you cut the line from the end of the motor, it is useless, and the implementation resistance will be great at this moment, so you can only find a car to pull it to the maintenance point to repair the motor.

Note: Because the brushless motor of the electric vehicle is a permanent magnet three-phase AC motor, it is a high-efficiency reversible three-phase alternator rotating magnetic field motor, which will be in a state of power generation during the implementation, and the output will be very difficult if there is a short circuit to promote it (it is in the open-circuit no-load state when it is implemented normally without failure).

Where electric vehicles are prone to problems in use:

1. Electric vehicle puncture, puncture is a common fault, if the electric vehicle often punctures, the main reason is that the tire used is too thin, it is recommended to directly replace the thickened tire. Avoid exposing the electric vehicle to the sun during daily use and when parking, and do not inflate the tires of the electric vehicle too much.

Ride on bumps, uneven surfaces with small stones, and regularly check that your wheels are in good condition.

2. The instrument indicator light is not lit, when the key is inserted to start the vehicle, the instrument indicator light is not lit, the reason may be that the power line falls off or the contact is poor, and the connecting wire in the battery box falls off, which should be dealt with and repaired in time.

When starting the vehicle, the indicator light is not on, and the rear wheel power is very large when pushing the vehicle, as if it is braked, it may be that the controller is damaged, and at this time, it can be pushed normally by unplugging the controller connection plug.

3. The battery is short-circuited, not stored electricity, in the process of electric vehicle use, the following mileage of the electric vehicle suddenly drops more than ten kilometers in a short period of time, it is very likely that at least one of the battery pack has a broken grid, plate softening and other short circuit phenomena, at this time should be checked in time, regenerated or grouped, and the battery life should be prolonged.

There are two causes of this situation, namely: The first is because the controller (three-phase AC inverter) is suddenly damaged by high heat, and the output three-phase power supply forms a short circuit between the components (at least there is a short circuit between the two phases), and the motor is in a short-circuit power generation state (working in the state of energy consumption braking and braking) when it is pushed, which makes it very difficult to push. Workaround:

Remove the circuit connected to the motor by the controller, so that the motor can get rid of the short circuit of the controller, so that the motor is in the working condition of no-load operation of power generation when it is implemented, so that the implementation becomes easy. Go to the repair point and replace the controller with a new one. (This situation is more) The second is caused by a sudden inter-turn short circuit inside the motor, even if the circuit is cut from the end of the motor at this moment, it is useless, and the implementation resistance will be great at the moment, so you can only find a car to pull it to the maintenance point to repair the motor.

This situation is less) Note: Because the brushless motor of the electric vehicle is a permanent magnet three-phase AC motor, it is a high-efficiency reversible three-phase alternator rotating magnetic field motor, which will be in the state of power generation during the implementation, and the output will be very difficult if there is a short circuit to promote it (it is in the open-circuit no-load state when it is implemented normally without failure). If you still have questions, please feel free to ask!

1. Portable fast chargers can be used:When riding an electric vehicle on the road, make sure to check the battery level of the car in time every once in a while. If you feel that the battery is low, try not to ride an electric car too fast.

It is recommended to drive at a constant speed to the surrounding households, and if you meet more humane people, you can take out a portable fast charger to charge the electric car for a while.

2. With the help of boosters:When you go out on an electric car, the place where you go is sparsely populated, and the car is out of power, it is very troublesome. Because most electric cars are bulky and heavy, it is quite laborious to push, but some cannot be thrown on the side of the road.

In this case, it is recommended to use a special booster for electric vehicles.

3. Request for assistance:If there are other electric cars or cars at home, then you can ask the other party to bring a rope to slowly drag the electric car home.

Precautions for driving electric vehicles.

Drivers of electric vehicles driving electric vehicles on the road shall comply with relevant national road traffic safety laws and regulations, and shall not have traffic violations such as running red lights, going in the opposite direction, drunk driving, driving on motor lanes, illegally carrying people, and driving with one hand. Luck and momentary indulgence are highly likely to lead to tragedy.

Electric vehicles should regularly check the braking, steering and lights (especially the vehicle taillights, intact taillights can effectively prevent night rear-end traffic accidents) and other vehicle safety facilities, and the failure to be eliminated in time. The electric tricycle has a simple structure and poor braking performance, which can not guarantee the safety of passengers and drivers, and once a traffic accident occurs, it is easy to cause the tragedy of mass deaths and injuries.

1. Start the trolley

Trolley start is the most familiar and effective emergency starting method, but this is a last resort and can not be used often, because there is a certain amount of damage to the engine and clutch, and automatic transmission vehicles should especially avoid using this method to start.

2. The most reliable:

Contact the ambulance. The most reliable way is to contact the rescue vehicle in time, and then connect the jumper cable and temporarily charge the rescue vehicle to start the engine.

3. Spare cable charging:

In order to avoid the battery not being able to be charged when it is empty, the owner should prepare a jumper cable in the car, which can be bought in the general auto parts store. However, when connecting jumper cables, it is important not to misconnect the jumper cables in the order in which they are connected. It is necessary to first connect the positive terminal of the dead battery with the positive terminal of the rescue vehicle battery, and then connect the negative terminal of the rescue vehicle battery with the metal part in the engine compartment of the dead car.

In fact, currently, there are many ways to make a pure electric vehicle suddenly lose power while driving. Finally,Pure electric vehicles are basically equipped with on-board charging equipment。If you are driving on national roads such as urban and rural areas, if you are really worried that the battery will run out of energy.

Then, it is also possible to charge the service station or local residents. The 220V battery only carries a charging unit with the vehicle. In general, it is also possible to negotiate with villagers or service stations and borrow plugs for charging.

Now more and more people buy cars, although the car has become an important means of transportation, but there are also people who choose other means of transportation, such as the battery car, it is small and does not take up much space, but do not have to worry about traffic congestion, you can freely shuttle between the traffic jams.

Charging, bicycle can be ridden, but very tired, motorcycle can only be pushed, many places on the side of the road also have electric vehicle fast charging stations, although the charging is fast, but because it is the use of high current forced charging, so it hurts the battery.

Call ** to call a friend to help pull it back. 2.See if there is a spare battery to replace.

3.It is to get a booster in the car yourself, so that if there is no electricity, it can be used to push the cart. 4.

It's just a matter of finding a place to recharge.

If you run out of power, first check if there is a fast charging station nearby, charge for a while before leaving, and if it is not far from home, you can push it home directly. If it's far away, find someone to help pull it away.

If the battery is out, push it to find a repair shop first, see if there is a fast charging station, charge it for a while and then leave, if it is not far from home, you can push it home directly.

1. See if there are convenience stores, supermarkets, electric vehicle maintenance departments, and battery maintenance departments around, and there are generally fast charging stations in these places, which are specially prepared for half-way battery cars without power or emergency preparedness. Excessive current is easy to damage the battery, and long-term use of the battery will heat up and change the drum, affecting the service life of the battery.

You can push it away.

You can find a charging place to charge.

It can also be called a tricycle or.

Other cars pulled up the tram and left.

Hahaha (hiahiahia

You can leave the tram and walk on your own.

The treatment method for the battery car to run out of power halfway is as follows:1. When the electric vehicle is out of power, you can turn on the ACS button to let the electric vehicle continue to move forward. After the ACS button is activated, the electric vehicle will turn on the automatic charging mode, and in addition, the automatic clutch function will also be activated, and the electric vehicle without power will release the stored reserve power and continue to move forward.

2. Convert voltage to make the battery life of the electric vehicle. People who want to make a range for an electric car in this way need to know some common sense of circuits. The way to do this is to manipulate the controller under the dashboard or saddle to change the battery to a low-voltage line, which will allow the electric car to continue riding for a certain distance.

3. Step on the pedals, ride the bike to the nearest maintenance department or fast charging station, and connect the charger for charging. Electric vehicles that meet the new national standard standards are equipped with pedals, commonly known as pedals, if you ride such an electric car halfway without power, you can step on the pedals and let the electric car continue to move forward.
