1. a kind of detection method of battery micro-short circuit, which is characterized in that including:

  • The target initial cells parameter value that target battery is carved at the beginning is obtained, and determines virtual reference battery when described initialThe reference initial cells parameter value at quarter, under the conditions of given identical excitation, response and the mesh of the virtual reference batteryThe response for marking battery is identical;

    Obtain target battery parameter value of the target battery in given time;

    According to the target battery parameter value and the reference initial cells parameter, determine the virtual reference battery describedThe reference battery parameter value of given time;

    The difference of the target battery parameter value and the reference battery parameter value is calculated, and the mesh is determined according to the differenceIt marks battery and micro-short circuit occurs.
