An Automotive Battery Management Current Sensor is an important component used in modern vehicle battery management systems (BMS) to measure the electrical current flowing into and out of a battery pack. Accurate current measurement helps the BMS monitor battery operation, estimate the state of charge (SoC), detect abnormal conditions, and support efficient energy management. These sensors are particularly important in electric vehicles (EVs), hybrid electric vehicles (HEVs), and plug-in hybrid electric vehicles (PHEVs).
