The maintenance methods for electric vehicle batteries can be summarized in the following three points:
1. Regular charging and maintenance: Avoid low battery storage: The battery should not be stored in a low battery state, and should be charged promptly after use to prevent sulfation and affect battery life. If the battery is not used for a long time, it should be recharged once a month to maintain its health. Mastering charging time: Charging time should not be too long to avoid overcharging. In general, a charging time of about 8 hours for batteries is more suitable. If it is a shallow discharge, the battery will quickly be fully charged. At this time, it should be avoided to continue charging to prevent overcharging from causing the battery to heat up and reduce its lifespan. At the same time, be careful not to charge frequently and try to charge when the battery is about 30% full.
2. Pay attention to the usage environment: Avoid high temperature environments: Charging or using batteries in high temperature environments can accelerate battery aging and reduce battery performance. Avoid exposing electric vehicles to high temperatures and scorching sun, and choose a cool and ventilated place when charging. Control charging temperature: The optimal temperature for charging electric vehicle batteries is around 25 ℃. When charging, try to choose a dry, ventilated, and sun free environment to avoid battery overheating.
3. Proper use and maintenance: Avoid high current discharge: When starting, carrying passengers, or going uphill, electric vehicles should try to use pedal assistance to avoid instantaneous high current discharge, which can protect the battery plates and extend the battery life. Pay attention to load: Avoid overloading electric vehicles to reduce the situation of instantaneous high current discharge of batteries and protect battery performance. Keep the battery clean: Regularly clean the dust and dirt on the battery cover, keep the battery dry and clean, to prevent the battery from discharging on its own. Stable voltage charging: Use a suitable charger to ensure that the charging voltage is stable and meets the standard, avoiding voltage fluctuations that can damage the battery.
By regularly charging and maintaining, paying attention to the usage environment, and using and maintaining them correctly, the service life of electric vehicle batteries can be effectively extended, and the range and safety of electric vehicles can be improved.
