What are the maintenance techniques for electric vehicle batteries?

First, protect the charger. There are instructions on protecting the charger in the general operating instructions. Many users do not have the habit of reading the manual, and often think of looking for the manual after the problem. It is often too late, so it is very necessary to read the manual first. In order to reduce costs, the current chargers are basically not designed with high vibration resistance. In this way, the chargers are generally not placed in the trunk and basket of the electric bicycle. Under special circumstances, it must be moved, and the charger must be packed with foam to prevent vibration. After many chargers undergo vibration, their internal potentiometers will drift, causing the entire parameters to drift, resulting in abnormal charging status. Another thing to note is to keep the charger ventilated when charging, otherwise it will not only affect the life of the charger, but also may cause thermal drift and affect the charging state. This will damage the battery. Therefore, it is also very important to protect the charger. Second, correctly grasp the charging time. Under normal driving conditions, if the red and yellow indicator lights of the electricity meter are both on, it should be charged; if the yellow light is off and only the red light is on, the charging should be stopped as soon as possible, otherwise the battery will be overcharged. Discharge and shorten the life. Some people are accustomed to charging every time before going out. Sometimes it only takes a short time to recharge. At this time, the charging time should not be too long, otherwise it will overcharge and cause the battery to heat up. Under normal circumstances, the average charging time of a car battery is about 10 hours. Overcharge, overdischarge and undercharge will shorten the battery life. If the battery temperature exceeds 65°C during the charging process, stop charging immediately. Third, prevent the plug from heating up during charging. The 220 volt power plug or charger output plug is loose, the contact surface is oxidized and other phenomena will cause the plug to heat up. Excessive heating time will cause the plug to short circuit or poor contact, damage the charger and battery, and bring you unnecessary losses. Therefore, when the above situation is found, the oxide should be removed in time or the connector should be replaced. Fourth, it is strictly forbidden to expose to the sun. The battery that has been exposed to the sun will lose water due to the increased internal pressure, which will cause the battery activity to decrease and accelerate the aging of the plate. Fifth, charge it every day. Even if your battery life is not long, it can be used for 2 to 3 days with a single charge, but it is still recommended that you charge it every day, so that the battery is in a shallow cycle state and the battery life will be prolonged. Some early mobile phone users think that it is best to charge the battery after it is basically used up. This view is wrong. The memory benefit of lead-acid batteries is not so strong. Frequent discharge of electricity has a greater impact on the life of the battery. In most chargers, after the indicator light turns to indicate full charge, the battery charge may be 97% to 99%. Although only 1% to 3% of the battery is under-charged, the impact on the continuation capacity is almost negligible, but under-charge accumulation will also be formed. Therefore, after the battery is fully charged, it is still possible to continue to float as much as possible, which is also useful for suppressing battery vulcanization have benefits.
