Battery Monitors & Balancers

Battery monitors capture key battery parameters such as voltage, current and temperature and relay this information to a microcontroller. Battery balancers offer cell balancing solutions to optimize battery system performance. Our battery monitors and balancers contain an analog front-end with digital interfaces and communication, and/or functionality to implement active external or passive internal and external balancing. These devices form a part of a complete monitoring and balancing solution for next-generation high-power systems such as electric vehicles (EVs), power tools, energy storage systems and e-mobility applications.
