The BMS consists of Battery Management Controller (BMC), Cell Supervising Circuits (CSCs) and Battery Junction Box (BJB). Functions include functional safety, determination of State of Charge (SOC) and State of Health (SOH), monitoring and balancing of the high voltage battery cells, control of. . In this article, we will discuss battery management systems, their purpose, architecture, design considerations for BMS, and future trends. Ask questions if you have any electrical, electronics, or computer science doubts. This is especially important for lithium-ion technology, where the batteries must be protected against. .
