According to Battery.com.cn, lead-acid batteries are the main batteries used in electric vehicles. The batteries are not worn out but are damaged. It is by no means an alarmist. The battery charging performance is good for the maintenance and service life of electric vehicles. Performance plays a pivotal role and must be taken seriously. 1. The discharge depth of the battery has a great influence on the cycle life of the battery. This is because the deeper the depth of discharge, the larger the amount of expansion and contraction of the electrode, and the more the active material of the positive electrode falls off, thus losing the discharge characteristics and degrading the performance until the end of life. Therefore, the battery should be used to avoid deep discharge as much as possible, so as to be shallow and diligent, the general situation should be: the battery is best charged with a discharge depth of 50%-70%. 2. After the battery is discharged to the termination voltage, continuous discharge (overdischarge) will seriously damage the battery. This is because irreversible sulfation is easily formed at this time, which makes the charge recovery ability worse or even impossible to repair. Therefore, the battery should be protected from overdischarge when used. "Undervoltage protection" is an effective measure. The "undervoltage protection" measure is controlled by the electric vehicle controller, but since the electric vehicle such as the electric vehicle instrument and indicator light is not controlled by the controller, the electric vehicle lock starts to use electricity once it is closed, although the current is small, If it is discharged for a long time, the battery will be over-discharged. Therefore, it is not allowed to unlock for a long time, and should be turned off immediately when not in use. 3, lead-acid batteries are particularly afraid of loss of electricity and discharge, the loss of battery placed for 3-7 days, there will be permanent damage, therefore, please charge the battery as soon as possible after use. For batteries that are not used for a long time, the battery should be charged once every 15 days to compensate for the loss of self-discharge when the battery is stored. 4. The charging current should be less than or equal to the charging current that the battery can accept. Otherwise, the excess current generated by overcharging will cause the electrolyzed water to be consumed too quickly and cause serious gassing. After a long time, the charging will become It is very difficult, so it is possible to prevent overcharging as much as possible during charging. Chargers made by regular manufacturers ensure that the battery is not overcharged. 5. The electric vehicle battery runs during the high temperature season, and there is mainly a problem of overcharging. Therefore, in summer, the battery temperature should be reduced as much as possible to ensure good heat dissipation, to prevent charging after sun exposure, and to stay away from heat. In the case of low temperature, charging mainly suffers from poor charging acceptance and insufficient charging to cause the battery to lose power. In case of low temperature, anti-freeze measures should be taken, especially when charging, it should be placed in a warm environment, which is beneficial to ensure sufficient electricity, prevent irreversible sulfation, and prolong the service life of electric vehicle batteries.
