Application: Battery Management Systems

The monitoring of rechargeable batteries is critical because of the high consumer demand for electric vehicles. BMS ensures a safe battery operation while optimizing the battery pack’s life. In addition, BMS monitors battery charging and prevents it from overheating.

The high breakdown voltage of 38-Q PhotoDMOS relays makes them ideal for BMS applications that have high-voltage requirements. PhotoDMOS relays contribute to the safer operation of BMS because there are no sticking and welding failures typical for mechanical relays. Furthermore, 38-Q series relays are smaller than comparable mechanical relays, which reduces the BMS board area’s size.
