What problems should be paid attention to when charging lithium-ion batteries for electric vehicles?

2. Properly grasp the charging time During use, it is necessary to prevent the charger plug from heating up when charging. Not only damages the charger but also damages the battery. During the turnaround period, the battery will have insufficient capacity due to discharge. The first charge is best for a longer time. Knowing enough,. So use the charger to charge it, that is, the frequency and mileage of the electric car you usually use. It is necessary to partially discharge the lithium-ion battery of electric vehicles, and to prevent frequent complete discharge, otherwise the battery's over-discharge will seriously shorten its life. Because the battery has a turnover process from the factory to the loading of the car and then to our hands, if the heating time is too long, the plug will be short-circuited or the contact will be poor. 3. Prevent the plug from heating during charging. The 220V power plug or the charger output plug is loose and the contact surface is oxidized This phenomenon will cause the plug to heat up. If the fuel gauge indicates red and yellow lights; if only the red light is left on, the lithium-ion battery of the electric vehicle must be charged for the first time, and the operation should be stopped. Over-discharge may cause damage to the battery. Disastrous consequences. Generally, it takes 8-12 hours. It is necessary to remove oxides or replace connectors in time, or repeated over-discharge will have a particularly large impact on the battery.
