[0015] The battery capacity evaluation method includes four steps: power-on capacity estimation, non-end-discharge charge-discharge capacity calculation, end-discharge capacity calculation, and full capacity update;
[0016] The described power-on capacity estimation process is as follows: When the system is powered on, the power-on capacity estimation module checks the open circuit voltage value of the single battery according to the detected open circuit voltage value, and queries the capacity ratio corresponding to the open circuit voltage in the open circuit voltage table (OCV_TABLE table) , And multiply this capacity ratio by the design capacity to estimate the battery’s initial power-on capacity;
[0017] Where OCV_TABLE is defined as follows:
[0018] struct OCV_TABLE OCV_LFP40_1=
[0019] {
[0020] {2000,2961,3170,3192,3203,3240,3259,3273,3280,3281,3282,3282,3283,3293,3320,3324,3324,3325,3325,3328,3500},
[0021] {0,5,10,15,20,25,30,35,40,45,50,55,60,65,70,75,80,85,90,95,100...
