Knowledge of battery maintenance:
1. Maintenance of new batteries
The necessary visual inspection should be carried out before the new battery is installed, and it can be used directly after the inspection is free of defects. The battery is mostly half-full before leaving the factory, and the battery has been aging, and there is no need to perform special activation again. Before charging a new battery, ensure that the charger matches the battery to avoid battery damage.
2. Instructions for fast charging
For non-fast-charge series batteries, it is not recommended to use fast-charge devices to quickly charge the batteries. Fast charging will make the material transfer produced by the internal electrochemical reaction of the battery fail to keep up with the charge transfer, and the electrode material will produce large irreversible changes and lose capacity.
3. Battery storage
When the battery is not stored for a long time, the battery should be charged to 50%-70%, and the storage temperature should be below 25ºC.
4. Battery charging
When using an electric vehicle charger to charge an electric vehicle, you should first connect the charger to the electric vehicle, and then connect the charger to the power supply. If the sequence is reversed, it will easily cause a short circuit. Keep ventilated when charging, and place the charger on non-flammable objects, as the flammable parts of the vehicle.
5. Daily maintenance
During normal use, avoid overcharging and overdischarging the battery. During use, if the battery life drops rapidly, you should find professional maintenance personnel to inspect the vehicle and the battery in time, and you must not disassemble the battery for inspection. When used at low temperatures, the problem of reduced range may occur, which is a normal phenomenon. Care should be taken to avoid extending the range by increasing the charging time. When using it under high temperature in summer, it is strictly forbidden to expose the battery to the sun, charge it, and charge it directly without heat dissipation after use.
