Title:
METHOD AND SYSTEM FOR MEASURING ISOLATION RESISTANCE OF BATTERY PACK ARRANGED ON VEHICLE CHASSIS
Document Type and Number:
WIPO Patent Application WO/2014/051284
Kind Code:
A1
Abstract:
The present invention provides a system for measuring an isolation resistance. The system comprises a voltage source configured so as to be electrically connected to first and second electrical terminals. The system further comprises a voltage meter for measuring a first voltage level between the first electrical terminal and a vehicle chassis, and measures a second voltage level between the first electrical terminal and the vehicle chassis when a resistor having a set resistance level is electrically connected between the first electrical terminal and the vehicle chassis. The voltage meter measures a third voltage level between the second electrical terminal and the vehicle chassis. The system further comprises a microprocessor configured so as to determine a first isolation resistance value on the basis of the first voltage level, the second voltage level, the third voltage level and the set resistance level
