Focus on explaining constant voltage charging and floating charging

Constant voltage charging During the charging process, the charging in which the voltage of the charging power supply always maintains a constant value is called constant voltage charging.If the charging power supply voltage is 2.3V/section, the water consumption during the charging process can be reduced to a very small extent.

Constant current charging

Constant current charging

In the charging process, the charging method with constant charging current from beginning to end is called constant current charging. Constant current charging can make the battery charge a certain amount of electricity quickly, which belongs to compulsory charging. This method is often used in battery supplementary charging, especially in

Detailed analysis of the initial charging of the battery

Usually, the first charge after the battery is unpacked is called the initial charge. For batteries that need to be injected with electrolyte, there is a process of “initial charging”. The initial charging mentioned here includes all the charging and discharging operations of the battery during the period from unpacking
