Some maintenance knowledge about electric vehicle batteries

The length of life of an electric vehicle battery has a lot to do with the habit of using it. Lead-acid batteries have no memory, so the rapid reduction of capacity is mainly due to some reasons such as battery vulcanization and “water loss” and “debt loss”. The battery is most afraid of “defective power” under voltage, battery often “depleted”. The battery plate is extremely vulnerable. In reality, up to 70% of the electric vehicle battery capacity is reduced by the strong current (starting current) when the electrode plate is discharged (electrical motor is particularly obvious), and the electrode plate strain is a physical damage of the battery. The damage cannot be repaired. Therefore, "every day with the car, every day charging", to ensure that the battery has sufficient voltage at any time becomes inevitable.

Users generally believe that maintenance-free batteries do not need to add water, in fact, this statement is wrong. Maintenance-free batteries generate heat during charging and high-current discharge. If there is heat, water will evaporate. Although the process of water evaporation is very slow, the amount of accumulated water evaporation cannot be ignored for a long time. Therefore, the battery should be replenished once every 6 months or so, so that the service life of the battery will be prolonged. The starting current of the electric vehicle is very large, especially the electric motor of the high-power motor, and the starting current is larger. The high current is very harmful to the battery plate. The best way is to start the electric car before riding. Of course, many electric motorcycles do not have a riding device, and there is no way.

After the battery is used for a period of time, some active substances will inevitably sink. If the active substances are not activated in time, it will inevitably have some impact on the capacity of the battery. Therefore, when using electric vehicles frequently, it is necessary to make batteries for each season depth discharge once. In addition, the charging process of the new battery is generally 6-8 hours. When the battery is fully charged, the charger will light green. If the charging time is too long, it is necessary to check whether the voltage protection device of the charger is damaged. If it is damaged, it needs to be replaced in time. Otherwise, it is easy to charge the battery. In addition, the charger should not buy a fast charger, and the fast charging also has damage to the battery plate. When the battery is not used for a long time, the battery should be charged at least once a month. The purpose of this is to prevent the battery from being vulcanized and "depleted" due to excessive battery storage time.

Preventing the battery from exploding will cause the battery temperature to rise, so be careful. Use the battery protector as soon as possible, that is, the pulse generator, the pulse is uninterrupted to eliminate the vulcanization of the battery, so that the plate is always "clean", thus extending the battery life, but it has little effect on the large current damage of the battery plate.
