When charging an electric vehicle, it is intermittent. What is the reason and how to solve it?

The battery has been undervoltaged, causing the motor to stop and spin. If the electric car battery.

In the case of an undervoltage state, the motor will stop and rotate from time to time to protect the battery. For this situation, it is generally normal and can be solved even if it is charged. However, when the battery is undervoltaged, continuing to drive will cause some damage to the battery.

Therefore, electric vehicles should be charged in a timely manner.

Precautions. If water enters the electric vehicle circuit or the contact is poor, it will also cause the motor to stop and rotate. In this case, it is generally necessary to go to a professional repair shop for inspection and repair the line.

In addition, there may also be some faults inside the motor, such as the motor phase loss fault, etc., for this kind of problem, you can only choose to go to the repair shop for repair. In fact, for users, if the motor has the problem of stopping and running, it is necessary to find out the cause as soon as possible, and if they can't solve it. Then, you need to go to a repair shop for repairs.

Did your charger have a big crash? Intermittent charging of the charger may be caused by excessive vibration or moisture, which may cause wiring problems. In addition, the loosening of the battery wiring is also a reason.

You can go to the mall where you bought your car to check, and it is generally warranted within one year.

It may be that the battery is broken, or it may be a lack of water, and it is necessary to check it specifically.

After a month of use, the internal power loss of the tram on the frame is too heavy, causing the voltage to be lower than the safe charging voltage.

Therefore, in this case of charging, there will be a charger charging indicator that jumps non-stop. You should be fine after 1 hour of charging.

That could be that your battery is not storing power, or there is a problem with the charger, it can't be charged, and then the charger jumps to the automatic protection gear, turns green, etc. You'd better check both.

1. The battery of the electric vehicle is aging

Normal lead-acid batteries.

The service life is about 350 times of charging and discharging, which means that every time it is charged, it accelerates the aging of the battery, according to the calculation of 2 days of charging once, basically a year the battery will appear serious aging, the aging of the battery will cause the charging will jump the light prematurely, it feels like it is fully charged, in fact, there is only less than 50% of the capacity of the new battery, which leads to the fact that the power of the dashboard is quickly displayed as soon as the electric vehicle is started.

2. The battery quality of electric vehicles

If you buy a new electric vehicle, it doesn't take long to have such a problem, this situation should be considered, whether the battery is brand new, whether it is a refurbished battery, if these two situations are excluded, then it is necessary to consider the quality of battery production, if you encounter such a quality of unqualified batteries, you should contact the electric vehicle business in time, replace the new battery as soon as possible, otherwise there will be spontaneous combustion or other safety hazards.

3. The axle card of the electric wheel is too tight

If there is no problem with the battery itself, it may also be a problem with too much resistance of the electric vehicle, at this time it is necessary to insist on the electric wheel axle, because the riding time here is too long, there will be a large amount of dust and dirt stuck in the bearing, which will dry out the wheel oil and cause the wheel to be stuck and tight, and the motor will consume more electricity to run when driving, and if the hub has a slight deformation or the hub motor.

The central shaft is not lubricated enough, resulting in an increase in resistance, and the motor is prone to immobility or power loss.

4. There is a problem with the electric vehicle charger

There are few problems here, so many people will ignore it, if there is no problem with the above points, then it is likely that your charger has failed, resulting in the charger premature jumping light power failure, mistakenly thinking that it is fully charged, resulting in the actual battery power displayed as soon as it starts, and there is a problem with the charger, the master recommends changing the original charger, or going to a professional maintenance personnel to do adaptation, do not buy the charger online casually.

The display content of the smart display dashboard relies on the controller's data flood signal, and if the dashboard fails, the dashboard assembly should be replaced. In case of emergency repair, the knob and brake handle signals can be directly connected to the controller.

Light-emitting diodes.

The signal acquisition and signal processing of the instrument use digital logic chips, and the circuit does not depend on the controller circuit and can work independently. Some electric vehicle handlebar and brake handle signals pass through the instrument panel and then output to the controller. In the event of an emergency, the lead wires of the handle and brake handle can be supplied directly to the controller.

Summary. The electric vehicle charger will be disconnected after charging for a while, and several situations will be analyzed.

There is a problem with the first charger.

Poor contact of the socket.

Line fault. If it is said that it is charged at home, you can drive the car to the charging station or the public charger of the radio network for charging, if the charger can be charged normally, then you have to check the charging cable of the portable charging station at home and the power supply system of the motor, for example, the ground wire is not in good contact, if the charging station is not charged, then you should consider whether there is a short circuit or virtual connection phenomenon in their interface and the line between the interface and the controller. This will have to be further tested at the repair shop.

The charger of the electric liquid cave car will be disconnected after charging for a while, and several situations will be analyzed: First, there is a problem with the charger. Poor contact of the socket. If the line fault is said to be charged at home, you can drive the car to the charging station or the radio network with a public charger for charging, if the charger can be charged normally, then you have to check the charging line of the portable charging station at home and the power supply system of the motor, for example, the ground wire is not in good contact, if the charging station is not charged, then you should consider their interface and the line between the interface and the controller, whether there is a short circuit state buried back or virtual connection.

This will have to be further tested at the repair shop.

Summary. 1. The battery power is too low: when the battery power of the electric vehicle is too low, the charger will automatically disconnect the charging, at this time, you can check the battery level, if the power is less than 20%, you can try to recharge.
