What should be paid attention to when charging the battery of electric vehicles

Now electric vehicles are popular, but a series of problems have arisen, the most important one is the charging problem of electric vehicles. Small electric vehicles (electric vehicles) are a new type of transportation in the environment where energy is increasingly depleted and the central government vigorously advocates new energy vehicles. Well, here comes the problem again. Small electric vehicles are different from traditional gasoline vehicles. There are places that need special attention in use and maintenance. Improper operation may affect the safety and service life of the vehicle. Therefore, when using it, we must understand some common sense.

For electric vehicles, the battery is equivalent to its “heart”, which controls the forward power of the car. During the charging process, car owners need to be particularly careful about the following points.

First of all, the battery should not be overcharged or overdischarged. The editor has previously learned from relevant experts that overcharging and discharging the battery will reduce its service life. Overcharging will cause the battery to heat up, and in severe cases, it may cause dangers such as spontaneous combustion and explosion. While driving, if the power meter indicates the red light area, the driver needs to stop running and charge as soon as possible, otherwise, the battery loss rate will increase greatly in the long run. It is understood that the average charging time of the general battery is about 10 hours. It is necessary to control the charging time. If the battery temperature exceeds 65 degrees, the charging should be stopped.

Second, it is best to charge it every day. For many commuters, it may be enough to charge the car once every two or three days. However, some experts suggest that don’t try to save trouble and charge frequently every day, so that the battery can be in a state of shallow cycle, which is more conducive to prolonging the service life.


Finally, attention should also be paid to the phenomenon of poor contact between the plugs at both ends of the charging cable. Poor contact will cause the plug to heat up. Once the heat is too long, a short circuit may occur, which will damage the charger and battery. Therefore, the owner also needs to check in time and replace the connector in time. There are also two points that need special attention when driving for a long time.

First, you should avoid power-loss parking. Electric vehicles are different from traditional gasoline vehicles. They have their own “unique taste” for the state of the vehicle parked. If you leave it on your stomach for too long before using it, it will “rebel”. The principle is this, when the electric vehicle is parked under the condition of power loss, the battery is prone to sulfation, which blocks the ion channel, resulting in insufficient charging and a decrease in battery capacity. Therefore, electric vehicles should keep their power active when they are idle.

Second, it should be deeply discharged on a regular basis. When the electric vehicle is about to run out of power, under-voltage protection will automatically occur, but during this process, its voltage is not stable, and it will fluctuate up and down, resulting in repeated under-voltage protection. So at this time, once you drive again, it will damage the battery a lot. Therefore, it is best to deeply discharge the battery on a regular basis, fully discharge it, and then fully charge it, which will protect the battery well.

What should I pay attention to when charging the battery of an electric vehicle? When the electric vehicle starts or goes uphill, try to avoid emergency braking and acceleration, because a large current discharge will be formed in the process, which will cause damage to the performance of the battery. Especially in the case of manned people, more attention should be paid.
