BMS Battery Management System Debugging Manual

This manual provides comprehensive debugging instructions for the BMS (Battery Management System) by Beijing Hangbo New Energy Technology Co., Ltd. It covers functional features including voltage monitoring (up to 24 channels, ±1.5mV accuracy), temperature detection (8 points per unit, -40°C to 125°C, ±1°C accuracy), current detection via Hall sensor (±1% accuracy), and SOC estimation (Ah integral error <2%, pure electric SOC error <±5%). The system architecture is distributed with a main control unit (BCU) and multiple slave units (BMU) communicating via CAN bus. Key functions include total voltage detection, insulation monitoring, UDS fault diagnosis, XCP calibration, thermal management, and online balancing. The manual details debugging processes for battery packs, application suggestions for fuses and power line connections, and handling of detection ports with fewer than 12 strings. It also covers relay control, data recording, power supply management, and national standard charging interface support.
