SOC-OCV mapping relation calibration method, device, equipment, medium and product

The invention discloses an SOC-OCV mapping relation calibration method, device and equipment, a medium and a product. The method comprises the following steps: receiving a first state of charge SOC and a first cycle index of a battery pack; obtaining a first OCV corresponding to the first SOC; based on preset experimental data, determining a first SOC-OCV mapping relation corresponding to the first cycle index; the experimental data is configured as a function among cycle index, OCV and SOC; based on the first SOC-OCV mapping relation, determining a first calibration OCV corresponding to the first SOC; and calibrating the first SOC-OCV mapping relation based on the first SOC, the first OCV and the first calibration OCV. 本申请公开了一种SOC-OCV映射关系校准方法、装置、设备、介质及产品，该方法包括：接收电池组的第一荷电状态SOC和第一循环次数；获取与第一SOC对应的第一OCV；基于预先设置的实验数据，确定与第一循环次数对应的第一SOC-OCV映射关系；实验数据被配置为循环次数、OCV和SOC之间的函数；基于第一SOC-OCV映射关系，确定与第一SOC对应的第一标定OCV；基于第一SOC、第一OCV和第一标定OCV，校准第一SOC-OCV映射关系。
