The correct charging method for electric vehicle lithium batteries is to charge according to the time and standard procedures, even for the first three times. Once the charger light turns green, charge for about 1-2 hours to stop charging. In particular, do not charge for more than 12 hours. General charging time is 3-5 hours.
Note:
Nowadays, electric vehicle lithium battery chargers are charged in three stages, which are divided into constant voltage and constant current stage. stage. step, trickle step. The first two stages are the main stages of charging. Once the battery is almost full, the light will turn green and enter the hold stage. To protect the battery, do not disconnect the power supply at this time and continue charging for 1-2 hours. hours, whati can effectively increase battery life, but after turning green, do not exceed 8 hours.
In general, when charging lithium batteries for electric vehicles, it is best to charge according to the specifications listed on them. If they are not available, it depends on the capacity of the lithium battery and its current. the charger, like 48V/20A for lithium batteries, if the charger is 5A, it will take a little more than 4 hours to charge, if it is a 10A charger, it will take a little more two hours, and if. it's a 20A charger, it will take an hour.
