Forward Auto technical exchange and sharing series: Battery–Maintenance of the battery

(1) Maintenance and maintenance of lead-acid batteries

  1. Power loss during storage is prohibited

    It is strictly forbidden to be in a state of power loss when the battery is stored. The state of power loss means that the battery is not charged in time after use. Storing the battery in a power-deficient state can easily lead to insufficient charging and a decrease in battery capacity. The longer the idle time in the power-loss state, the more serious the damage to the battery. Therefore, when the battery is not in use, it should be recharged once a month, so as to keep the battery in a healthy state.

2. Regular inspection

During use, if the continuation of the electric vehicle suddenly drops by more than ten kilometers in a short period of time, it is very likely that there is a problem with at least one battery in the battery pack. At this time, you should go to the sales center or the maintenance department of the agent for inspection, repair or matching. This can relatively prolong the life of the battery pack and save your expenses to the greatest extent.

During normal driving, if the red light and yellow light of the power meter indicate that it is on, it should be charged; if only the red light is left on, it should stop running and charge as soon as possible, otherwise the excessive discharge of the battery will seriously shorten its life. After the battery is fully charged, the running time is short, and the charging time should not be too long. Otherwise, overcharging will occur and the battery will heat up. Overcharging, overdischarging, and undercharging can shorten battery life. In general, the average battery charging time is about 10 hours.

3. Prevent sun exposure

Electric vehicles are strictly prohibited from being exposed to the sun. An environment with excessively high temperature will increase the internal pressure of the battery and cause the battery to lose water, causing a decrease in battery activity and accelerating the aging of the plates.

4. Avoid the plug heating when charging

Looseness of the 220V power plug or charger output plug, oxidation of the contact surface, etc. will cause the plug to heat up. Excessive heating time will lead to short circuit or poor contact of the plug, damage the charger and battery, and bring you unnecessary losses. Therefore, in the above situation, the oxide should be removed or the connector should be replaced in time.
