Method for balancing charging differences between rechargeable battery modules of battery for partially or completely electrically-driven vehicle, involves predetermining balancing duration required for balancing differences between modules

摘要

The method involves determining output charging condition of rechargeable battery modules (3, 4), and predetermining balancing duration required for balancing charging differences between the battery modules by using a computing device, where the computing device is connected with a determination unit in a data-transmitting manner. The balancing duration is determined based on characteristics of the battery modules, where the characteristics represent the charging condition. A charging and discharging model of one of the modules is stored in the computing device. An independent claim is also included for a device for balancing charging differences between rechargeable battery modules.
