1. A battery characteristic determining device adapted for determining at least one characteristic of a battery module, said battery characteristic determining device comprising:

  • a control module outputting a control signal when the battery module is in a charging state and an SOC (state of charge) of the battery module reaches a predetermined target value, so as to result in change of the current of the battery module to a predetermined test value for a predetermined test time period, the predetermined test value being such that the change of current causes a voltage of the battery module to decrease in the predetermined test time period; and

    a processing module coupled to said control module for receiving the control signal therefrom, upon receipt of the control signal, said processing module obtaining a voltage variation of the battery module during the predetermined test time period, and obtaining a C rate of the battery module with reference to the voltage variation.
