Battery Management Control
NXP solutions enable AD/DC chargers in hybrid electric vehicles (HEV). The AD/DC charger interfaces with the battery management system to ensure a proper charge of electricity of the cells until it fulfills high-voltage (HV) requirements. Our comprehensive portfolio provides the critical building blocks for high-performance, efficient and safe power management control system for electric traction motors.
