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.
Claims20
A battery control method applied to a battery comprising N battery systems, wherein the battery control method comprises:
- detecting whether a current value of the N battery systems is greater than a safe current, wherein the N battery systems are coupled in series, wherein each of the N battery systems comprises M battery cells, wherein the M battery cells are coupled in parallel, wherein N is an integer greater than or equal to one, wherein M is an integer greater than one, wherein the safe current is a current of a target battery system of the N battery systems, and wherein 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 when the current value is greater than the safe current.
A battery control apparatus applied to a battery comprising N battery systems, wherein the battery control apparatus comprises:
- a non-transitory computer-readable storage medium configured to store programming instructions;
- and
- a processor coupled to the storage medium, wherein the programming instructions cause the processor to be configured to:
- detect whether a current value of the N battery systems is greater than a safe current, wherein the N battery systems are coupled in series, wherein each of the N battery systems comprises M battery cells, wherein the M battery cells are coupled in parallel, wherein N is an integer greater than or equal to one, wherein M is an integer greater than one, wherein the safe current is a current of a target battery system of the N battery systems, and wherein 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
- adjust the current value of the N battery systems when the current value of the N battery systems is greater than the safe current.
