IVT sensors

Electric vehicles need to measure very precisely the traction battery’s state of charge and state of health in order to make an accurate estimate of the vehicle’s range. Shunt resistor-based, zero-offset battery sensing solutions from ams OSRAM enable automotive battery management systems to make very accurate current and voltage measurements which are required in this application. ams OSRAM offers a data acquisition IC for battery management, the AS8510, and a companion IC chip, the AS8525, for current measurement at the positive pole of vehicle battery.
