Abstract: A battery control method comprising detecting whether a current value of N battery systems is greater than a safe current, where the safe current is a safe current of a target battery system, and the target battery system has a largest resistance difference of parallel branch circuits respectively corresponding to M battery cells in the target battery system, and adjusting the current value of the N battery systems when the current value of the N battery systems is greater than the safe current.
