Embodiment 1
[0033] A method for accurately measuring battery health, characterized in that it mainly includes the following steps:
[0034]S1: When the battery is separated from the charging / replacing cabinet, start the recording device inside the battery to record battery parameters such as SOC, current, temperature, etc., and the operating status of the electric vehicle to obtain a data set; The device sends the collected voltage, current, temperature and battery charge state to the flash for recording and storage through the on-board communication; the recording time is not less than 5s, and the recording frequency is 1s / bar.
[0035] S2: When the battery is used up and put into the charging / replacing cabinet again and communication is established, the battery stops recording and uploads the data set recorded by the recording device;
[0036] S3: What disassembles the data set recorded in S2 into the following seven types of data:
[0037] 1) One type of data: the start value CH and s...
