Light electric vehicles (LEV)

Accurate, safe and secure BMS solutions for light electric vehicles

The light electric vehicle battery module, together with the battery management system, is a crucial technological sub-system for any electric 2-wheeler and 3-wheeler, since it drives the performance of the vehicle in terms of maximum torque and range. A highly efficient battery management system in a light electric vehicle will utilize the lowest drain-source on-resistance OptiMOS™ and StrongIRFET™ MOSFETs for maximum short circuit current capability and lowest continuous operation conduction losses, resulting in higher efficiency and range. In addition, with the latest AIROC™ CYW20829 Bluetooth® SoC along with the OPTIGA™ Authenticate S, wireless battery monitoring and diagnostics are seamless to implement.
