Abstract
The invention relates to the field of vanadium cells, in particular to a method for protecting voltaic pile in a vanadium cell test process. Due to the fact that a working relation between a vanadium cell management system and a charge-discharge tester is independent, now a software-hardware of the charge-discharge tester is fixed, high cost for updating the software-hardware is high. The technical scheme of the method includes that a contactor is added between the vanadium battery heap and the charge-discharge tester, and the contactor is controlled by a battery management system. In the normal charging process, the contactor is in a close state, when the vanadium battery management system detects that failures happen in the vanadium battery side part or an electrical part, a circulating pump operation of the vanadium battery side is stopped, the charge-discharge tester still charges the battery, and then the vanadium battery management system can detect charging current of the battery, if the charging current continues not to be equal to zero in the limited time, the battery management system can automatically shut down the circuit between the vanadium battery and the charge-discharge tester, and play a role in protecting the vanadium battery heap.
