Abstract
A battery management method includes verifying variance information of a physical quantity of each of a plurality of batteries, and identifying a target battery among the batteries based on the variance information. The battery management method also includes determining pack state information of a battery pack comprising the batteries based on state information of the target battery.
Claims22
A processor-implemented method for controlling a battery pack, the method comprising:
- verifying variance information of a physical quantity of each of a plurality of batteries, wherein the variance information corresponds to a variance in the physical quantity during a cycle, and the cycle comprises at least one of a full charge cycle, a full discharge cycle, a partial charge cycle, and a partial discharge cycle;
- identifying a target battery among the batteries based on the variance information;
- determining pack state information of the battery pack comprising the batteries based on state information of the target battery;
- and
- controlling the battery pack based on the determined pack state information.
A non-transitory computer-readable storage medium storing instructions that, when executed by a processor, cause the processor to perform a method, the method comprising:
- verifying variance information of a physical quantity of each of a plurality of batteries;
- identifying a target battery among the batteries based on the variance information;
- determining pack state information of the battery pack comprising the batteries based on state information of the target battery;
- and
- controlling the battery pack based on the determined pack state information.
An apparatus for controlling a battery pack, comprising:
- a memory configured to store a physical quantity of each of a plurality of batteries;
- and
- a processor configured to
- identify a target battery, among the batteries, based on variance information of the physical quantity, wherein the variance information corresponds to a variance in the physical quantity during a cycle and the cycle comprises at least one of a full charge cycle, a full discharge cycle, a partial charge cycle, and a partial discharge cycle,
- determine pack state information of the battery pack comprising the batteries based on state information of the target battery, and
- control the battery pack based on the determined pack state information.
