1. A battery management method applied to a battery management system BMS, wherein the battery management method comprises:
transmitting, under a condition that it is determined that a connection relationship between unfailing cells of a target battery pack changes when a target failure cell in the target battery pack is isolated from the unfailing cells, original configuration information of the target battery pack to a processing device, so that the processing device generates adjusted configuration information according to the original configuration information;
receiving the adjusted configuration information transmitted by the processing device, wherein the adjusted configuration information comprises an identification of the target failure cell;
performing management operations on the 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 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 battery management method when executed by the BMS is different from a storage area of the configuration information.
