Abstract: A battery voltage measuring circuit is provided to decrease the manufacturing cost of a BMS(Battery Management System) by using a single CPU(Central Processing Unit) for controlling plural photomos relays. A battery controller for a hybrid vehicle or an electric vehicle includes a high voltage battery(40), a voltage measuring circuit(50), and an ADC(Analog Digital Converter)(60). The voltage measuring circuit independently utilizes the power of an insulated power supply(70) to measure a voltage of the high voltage battery. The power supply supplies a voltage from a differential amplifier to positive and negative terminals, when a photomos relay is connected in forward and reverse directions, respectively. The photomos relay is included in the voltage measuring circuit. The photomos relays are insulated from each other.

Abstract: A system for measuring a current of a battery for an electric vehicle includes a current transducer, a voltage-to-PWM (PWM (Pulse Width Modulation) converter, and a power supply unit. The current transducer measures a battery current during a charge or a discharge of the battery, and generates a corresponding voltage signal. The voltage-to-PWM converter converts the voltage signal input generated by the current transducer to a PWM signal. The power supply unit supplies power to the current transducer.
