A Measuring Method about the Bus Insulation Resistance of Power Battery Pack

Abstract

For the shortcomings of insulation resistance detection method about battery pack, a novel detection method is introduced. This method can effectively realize the real-time measurement for the insulation resistance of the positive and negative bus, relative to the ground. In the dynamic conditions, improved the positive and negative bus insulation resistance measurement accuracy, more suitable for applications in integrated battery pack monitoring unit, it has a simple circuit, low power consumption, low cost hardware.
