Introduction to BMS
A Battery Management System (BMS) is an essential component in modern battery-powered applications. It plays a crucial role in monitoring, controlling, and protecting rechargeable batteries. The main functions of a BMS include measuring the battery's state of charge (SOC), state of health (SOH), and temperature. It also balances the cells within a battery pack to ensure uniform charging and discharging, which helps to extend the battery's lifespan and improve its performance. BMS is widely used in electric vehicles (EVs), energy storage systems, portable electronics, and other fields where reliable battery operation is required.
