Battery Management System (BMS)

The BMS is a critical component for ensuring battery safety. Traditional MOSFETs contain a body diode that prevents bidirectional blocking, necessitating back-to-back MOSFETs for charge-discharge protection in conventional BMS designs. Leveraging GaN's inherent lack of a body diode, Innoscience has developed the VGaN series specifically for BMS applications. A single VGaN device can replace two MOSFETs, reducing conduction resistance and heat generation by half while lowering temperature rise. This significantly decreases the PCB area required for the BMS power loop, facilitating more compact and lightweight battery pack designs. The solution enhances performance while reducing total system cost and improving product competitiveness.
