Charging control method and charging assembly

摘要

A charging assembly and a charging control method are provided for charging a battery pack according to an actual voltage of a battery in a battery pack. The charging assembly includes a battery pack having a battery with a rated charging current, a charger having a charging module for outputting an output voltage and an output current, and a charging circuit between the charging module and the battery. A method of operation includes: detecting the output current and the output voltage; calculating an actual voltage value on the battery; and determining whether to decrease or keep the output current or increase the output current of the charging module.

1. A charging control method for controlling a charger comprising a charging module for outputting an output voltage and an output current to charge a battery pack comprising a battery with a rated charging current, the charging control method comprising:
detecting an output current value I1 and an output voltage value U1 of the charging module; calculating an actual voltage value U2 on the battery according to U2=U1−I1×R, wherein R is an equivalent resistance value of a charging circuit between the charging module and the battery; determining whether the actual voltage value U2 is higher than or equal to a preset charging voltage value; and when it is determined that the actual voltage value U2 is higher than or equal to the preset charging voltage value, decreasing or keeping the output current of the charging module, otherwise increasing the output current of the charging module.
