Abstract This paper proposes an approach for measuring voltage of high voltage(HV) battery of plug-in hybrid electric vehicle(PHEV) and battery electric vehicle(BEV). The proposed methods use isolation resistor and isolation amplifier in order to measure high voltage which should be electrically separated from measuring circuit. In terms of practical applications their advantages and disadvantage are discussed and key design points are addressed by simulations. More importantly, the proposed methods are applicable to various applications such as on-board charger, inverter and battery management system (BMS) which are directly connected to HV battery in PHEV and BEV.
