The Battery Management System (BMS) PCB is the "intelligent monitoring core" of new energy battery packs, designed specifically for lithium batteries, energy storage batteries, and other scenarios. It integrates key functions such as cell voltage collection, temperature monitoring, balanced charging, State of Charge (SOC) estimation, and safety protection. Adopting high-precision detection chips and anti-interference circuit design, this PCB can real-time monitor the working status of each battery cell, avoiding risks such as overcharging, over-discharging, and overheating, extending battery service life, and ensuring the safe and stable operation of battery packs in new energy vehicles, energy storage power stations, portable devices, and other
