Abstract
The electric leakage detection method disclosed herein includes: total voltage measurement of measuring a total voltage Vwhich is an electrical potential difference between a total positive terminal open to be connectable with an external device and a total negative terminal open to be connectable with the external device; electric leakage voltage measurement of measuring an electric leakage voltage Vwhich is an electrical potential difference between a reference terminal (the total negative terminal) and the electric leakage occurring position (the third single battery); and an electric leakage occurring position determination of determining the electric leakage occurring position by calculating a ratio (V/V) of the electric leakage voltage Vto the total voltage V. This allows the number of single batteries between the reference terminal and the electric leakage occurring position to be estimated, and a detailed electric leakage occurring position to be determined.
