An electric leakage detection method includes: measuring a set of a first voltage and total voltage times to be recorded in a memory by the control apparatus in a state that one of first and second switches is closed and another of the first and second switches is opened; measuring, by the voltage detector, at least one second voltage corresponds to the total voltage whose difference from any one of the total voltages recorded in the memory is equal to or less than a voltage threshold value; computing a total insulation resistance between the storage battery group and the ground by using the total voltage, the first voltage, and the second voltage; and determining presence of electric leakage when a value of the total insulation resistance is equal to or less than an electric leakage threshold value.
