Battery Management System (BMS)

The Battery Management System (BMS) enhances performance and ensures functional safety for battery packs composed of multiple cells. Functional safety is critical as lithium-ion batteries can pose significant safety risks when operated outside their safe working range. After soldering and aging, our BMS product portfolio provides high measurement accuracy and supports ISO26262, achieving ASIL D functional safety levels.

We are committed to sustainable mobility and renewable grids, offering innovative BMS solutions that include a complete set of chipsets, universal software, and functional safety documentation for both wired and wireless BMS communication. Our reference designs help customers accelerate development and bring the latest BMS innovations to automotive and industrial applications.
