[0029] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solutions of the present invention more clearly, and cannot be used to limit the protection scope of the present invention.
[0030] like figure 1 As shown, an SOC adaptive correction method for a secondary battery includes the following steps:
[0031] 1) According to the battery manufacturer's recommended cut-off voltage value, set the upper and lower limit protection values of the operating voltage of the single battery, and change the protection of the battery management system to the upper and lower limit protection of the operating voltage of the single battery; use the battery management system to monitor the battery operation process in real time, Record the battery operation data from the upper voltage limit to the lower voltage limit. The battery operation data includes all single cell voltages...
