使用済み電池モジュールの修復方法

Japanese Patent JP7142697

B2

A method for repairing a decommissioned battery module, comprising the following steps: charging a decommissioned battery module to an upper limit voltage (S100); releasing a state of parallel connection between a plurality of single columns of cells in the decommissioned battery module (S200); leaving the decommissioned battery module charged to the upper limit voltage to stand for a preset time, and separately charging each single column of cells to the upper limit voltage (S300); discharging all the single columns of cells to a lower limit voltage (S400); and connecting the plurality of single columns of cells in parallel (S500). When repairing a decommissioned battery module, the described method for repairing a decommissioned battery module does not need to disassemble the decommissioned battery module into single cells, but maintains the entire form of the decommissioned battery module, releases parallel connection between a plurality of single columns of cells, and repairs each single column of cells. Compared with the conventional methods, the described method for repairing a decommissioned battery module has a low cost in repairing a decommissioned battery module.
