1. a method of leaking for detection of the cooling fluid of the electric battery from liquid cooling, described electric battery comprises positive terminal and negative terminal, described method comprises:

  • The first end of pickup wire is connected to one of the positive terminal of electric battery or negative terminal electrically;

    The second end of pickup wire is placed on to the position that the cooling fluid of leakage can be assembled;

    Measurement is from the Voltage-output of pickup wire;

    AndIf the Voltage-output of measuring is greater than predetermined voltage threshold, determines and exist cooling fluid to leak.
