Abstract
A charging assembly and a charging control method are provided for charging a battery pack in a fast charging voltage value which is greater than the rated charging voltage value. The charging assembly includes a battery pack, a charger and a control system configured to control the charger to charge the battery pack with a constant charging current. The method includes: detecting the open-circuit voltage of each battery cell and screening out a maximum open-circuit voltage value, calculating a maximum charging duration and controlling the charger to charge the battery cell assembly with a constant current when the charging voltage is equal to the fast charging voltage value or reaches the maximum charging duration.
