LEM releases a first of its kind high-voltage battery sensor that combines shunt and Hall effect technologies - Hydrogen Central

Current sensor operates from -40 °C to +125 °C with 2% accuracy at 500 A

LEM Electrical measurement technology specialist, has launched a new current sensing unit for battery management in electric vehicles (EVs). For the first time on the market, LEM has put together shunt and open-loop Hall effect technologies in a single part, called the Hybrid Supervising Unit (HSU), to meet the challenges of small footprint, low cost, and the highest safety level in EV battery management systems. The EV’s high-voltage BMS plays …
