The batteries’ conduction paths can be opened and closed using on-board field effect transistors (FETs) and on-board or external contactors. This enables charging and discharging currents to be reliably controlled. Depending on the controller chosen from the product family, communications between batteries and the BMS run via CAN, I/O interfaces, or wirelessly via Bluetooth LE. The company has also developed a 7kWh battery module scalable from 12 to 48V that needs no peripherals, and can be built into a variety of different vehicles. This means the battery module is suitable for recreational vehicles with independent power supply for example.
