The correct way to charge lithium-ion batteries for electric vehicles:
First, the initial charging is the same as usual, no special treatment is needed, and it takes eight to twelve hours to charge.
Secondly, it is necessary to use a dedicated charger supplied by the lithium-ion battery manufacturer for charging. When charging, first connect the output port of the charger to the battery, and then connect the charger to the power source.
Third, since lithium-ion batteries have no memory effect, they can be charged whenever needed, which is beneficial to battery life. It is recommended to charge for eight to twelve hours each time, and not for more than a day.
Fourth, if the battery is not used for an extended period, it should be charged for two hours every two months; otherwise, battery performance will degrade. Furthermore, avoid completely discharging the battery before recharging; it is best to charge and discharge it lightly as needed.
How to maintain lithium-ion batteries in electric vehicles?
I. Correctly determine the charging time
During use, the charging time should be accurately determined according to the actual situation, and the charging frequency should be determined by referring to the usual usage frequency and mileage.
2. Protect the charger.
Most user manuals contain instructions on protecting the charger. Many users don't have the habit of reading the manual and often only think of looking for it after a problem occurs, which is often too late. Therefore, reading the manual first is essential.
III. Periodic deep discharge
Performing a deep discharge periodically on a lithium-ion battery can also help activate the battery and slightly increase its capacity. A common method is to periodically perform a complete discharge. A complete discharge is achieved by riding a bicycle under normal load conditions on a flat road until the first undervoltage protection is triggered.
IV. Preventing high-current discharge
When starting, carrying passengers, or going uphill, avoid sudden acceleration of the lithium-ion battery in electric vehicles to prevent instantaneous high-current discharge. High-current discharge can easily lead to lead sulfate crystallization, which damages the physical properties of the battery plates.
