Step S4: the battery performance parameter in the mesuring battary charge and discharge process is gathered and preserved to second control module in real time; And the battery performance parameter of the mesuring battary of gathering is compared with the battery protection parameter that prestores; When arbitrary performance parameter reached the battery protection parameter that prestores in the battery performance parameter of the mesuring battary of gathering, the control second switch broke off.
8. battery testing method according to claim 7 is characterized in that, the battery protection parameter among said step S3 and the step S4 comprises battery voltage limit value, cell voltage lower limit, electric weight setting value and desired temperature.
9. according to claim 7 or 8 described battery testing methods, it is characterized in that, further comprising the steps of when arbitrary performance parameter reaches the battery protection parameter that prestores in the battery performance parameter of the mesuring battary of gathering among the said step S3:
1: the first control module of steps A sends the information that arbitrary performance parameter in the battery performance parameter of the mesuring battary of gathering reaches the battery protection parameter that prestores to second control module;
After 2: the second control modules of steps A received the information among the above-mentioned steps A1 that first control module transmits, the control second switch broke off.
10. according to claim 7 or 8 described battery testing methods, it is characterized in that, further comprising the steps of when arbitrary performance parameter reaches the battery protection parameter that prestores in the battery performance parameter of the mesuring battary of gathering among the said step S4:
Step B1: second control module sends the information that arbitrary performance parameter in the battery performance parameter of the mesuring battary of gathering reaches the battery protection parameter that prestores to first control module;
Step B2: first control module is controlled first switch and is broken off after receiving the information among the above-mentioned steps B1 that second control module transmits.
