Charging method
The main stream method includes: two stages charging method and three phase charging method at the present.
Two stage method: using the rapid charge method by constant current and constant voltage. First, charging by constant current to scheduled voltage value, and then, instead of constant voltage of the remaining charge. Generally two phase conversion between voltages is the second stage of the constant voltage.
The constant current charging
Constant current charging refers to the battery charging from beginning to end by fixed constant current charging.
Constant voltage charging
Constant voltage charging refers to the supply voltage of the charging is to maintain a constant value during the charging.
Trickle charge
Trickle charge is used to compensate for the battery capacity loss caused self-discharge when fully charged. In this way, the battery remains continuous small current in charging mode which approximate fully charged state, also known as maintenance charge (float charge).
