SMART HV BMS HIGH VOLTAGE CAR BATTERY MANAGEMENT SOLUTION

The hybrid and electric vehicle (EV) market is rapidly growing, and optimizing energy efficiency and extending battery life have become key factors determining the success of these vehicles. The high-voltage HV BMS smart battery management solution not only helps monitor and accurately control the state of battery cells but also optimizes energy distribution and consumption.

By applying advanced technologies, LEM specializes in the development and manufacturing of current sensors for battery management systems (BMS) and motor drive applications in cars, buses, and trucks. Through precise control of current in high-energy consumption applications for high-voltage battery management (BMS HV), LEM’s integrated CAB current sensing technology, using fluxgate technology, offers the best accuracy in the segment and high functional safety (ASIL). This feature has eliminated the need for additional backup sensors.

Furthermore, Shunt, Fluxgate, and Hall-effect are the preferred technologies for high-voltage automotive applications. While shunt technology is favored for its simplicity and excellent linearity, fluxgate offers better accuracy, particularly in terms of offset. The open-loop Hall-effect solution provides a cost-effective alternative for backup functions.
