High-Voltage BMS Reference Design
The transition to electric vehicles, renewable energy integration, and the need for resilient power supplies are driving the growing demand for battery energy storage systems (BESS). Battery Management Systems (BMS) are key to ensuring battery performance, safety, and lifespan.
In partnership with NXP Semiconductors, eInfochips has developed a 1500V production-grade BMS reference design suitable for a variety of high-voltage applications. It is a complete suite of BMS hardware, software and safety package encompassing product safety life-cycle libraries, documentation and compliant with safety standards such as IEC61508, IEC60730 and UL9540.
