Filter Design of Power Battery Resistance Measuring for New Energy Vehicle

Abstract:

In order to measure the internal resistance of new energy vehicle power battery precisely, the high quality factor analog band-pass filter circuit and switched-capacitor circuit was studied. And the circuit was redesigned by using a switched capacitor circuit for digital control. Combined with the requirements of vehicle battery internal resistance measurement, the resistance measurement system architecture which is based on microcontroller and programmable logic devices is proposed. Finally, the system is validated via error calculation and the actual experiments.
