Classification: CPC H | IPC H

Claim 6:
7. A battery management method applied to a processing device, wherein the battery management method comprises:
generating adjusted configuration information based on original configuration information of a target battery pack transmitted by a battery management system, BMS, and an acquired identification of a target failure cell in the target battery pack;
transmitting the adjusted configuration information to the BMS, so that the BMS performs management operations on unfailing cells of the target battery pack according to the adjusted configuration information, and
wherein the adjusted configuration information further comprises information of the unfailing cells of the target battery pack, and the BMS performing management operations on the unfailing cells of the target battery pack according to the adjusted configuration information comprises:
determining an adjustment coefficient of a performance parameter of the target battery pack according to the information of the unfailing cells of the target battery pack, wherein the adjustment coefficient is calculated by a number of the unfailing cells divided by a sum of the number of the unfailing cells and a number of the target failure cells;
calculating the performance parameter of the target battery pack using the adjustment coefficient and an original performance parameter of the target battery pack,
wherein the performance parameter comprises a charging characteristic parameter and/or a discharging characteristic parameter;
the charging characteristic parameter comprises at least one of a charging voltage, a charging current, a charging power, a charging state of charge, and a charging capacity;
the discharge characteristic parameter comprises at least one of a discharging voltage, a discharging current, a discharging power, a discharging state of charge, and a discharging capacity; and
calculating the performance parameter of the target battery pack comprises calculating a product of the original performance parameter and the adjustment coefficient,

wherein a storage area of a program that implements the management operations when executed by the BMS is different from a storage area of the configuration information.
