Method for estimating grouping efficiency, electronic device and storage medium

An electronic device, comprising:

• at least one processor;
• and
• a memory, which is configured to store at least one program;
• wherein the at least one program, when executed by the at least one processor, causes the at least one processor to implement:
• detecting initial capacities of a plurality of to-be-grouped battery cells, and grouping, among the to-be-grouped battery cells, battery cells whose initial capacities each satisfy a preset grouping capacity threshold range to obtain a first battery pack, wherein the preset grouping capacity threshold range is determined based on a nominal capacity of the to-be-grouped battery cells;
• detecting an initial SOC of each battery cell in the first battery pack, and grouping the battery cells in the first battery pack whose initial SOCs each satisfy a preset grouping SOC range to obtain a second battery pack;
• simulating a charging and discharging process of each battery cell in the second battery pack based on a preset charging and discharging strategy to obtain charging data and discharging data corresponding to the battery cell;
• and
• determining a grouping efficiency of the second battery pack based on the charging data, the discharging data, and the nominal capacity.

A non-transitory storage medium comprising computer-executable instructions which, when executed by a computer processor, are configured to implement:

• detecting initial capacities of a plurality of to-be-grouped battery cells, and grouping, among the to-be-grouped battery cells, battery cells whose initial capacities each satisfy a preset grouping capacity threshold range to obtain a first battery pack, wherein the preset grouping capacity threshold range is determined based on a nominal capacity of the to-be-grouped battery cells;
• detecting an initial SOC of each battery cell in the first battery pack, and grouping the battery cells in the first battery pack whose initial SOCs each satisfy a preset grouping SOC range to obtain a second battery pack;
• simulating a charging and discharging process of each battery cell in the second battery pack based on a preset charging and discharging strategy to obtain charging data and discharging data corresponding to the battery cell;
• and
• determining a grouping efficiency of the second battery pack based on the charging data, the discharging data, and the nominal capacity.
