Title:
漏電検出方法
Document Type and Number:
Japanese Patent JP7475321
Kind Code:
B2
Abstract:
The electric leakage detection method disclosed herein is first detection of turning at least one of the positive-side contactor 32 or the negative-side contactor 42 ON and detecting a value of a system electric leakage resistor Rz which is an electric leakage resistance of the entire electricity distribution system 100; second detection of turning both of the positive-side contactor 32 and the negative-side contactor 42 OFF and detecting a value of a power source-side electric leakage resistor RL which is an assembled battery 10-side electric leakage resistance; and first determination of determining which of the power source unit-side region or the electric device-side region is causing the electric leakage based on the values of the system electric leakage resistor Rz and power source-side electric leakage resistor RL.
