Three main types: Hall-effect sensors (contactless, good isolation), shunt resistor sensors (cost-effective, high accuracy), and fluxgate sensors (highest precision for demanding applications).
Accurate current measurement enables precise state-of-charge calculation, detects overcurrent conditions, monitors battery health, optimizes charging efficiency, and ensures safety compliance with automotive standards.
ISO 26262 for functional safety, ISO 16750 for environmental testing, AEC-Q100 for reliability, and SAE J1939 for communication protocols in commercial vehicles.
