Feature

The B2104 Battery Management System is designed for mini electric sightseeing cars, energy-storage battery packs, and low-speed new-energy vehicles. It supports a customizable 0–800V voltage platform and 8S–48S cell configurations with master-slave expandability. The system handles a continuous working current from -500A to 500A and is compatible with NCM, LMO, LCO, and LFP chemistries. It features 8-channel external NTC temperature sensing and operates from -30℃ to 85℃. Communication interfaces include CAN ×2 and RS485 ×1. Comprehensive protection functions cover over-charge, over-discharge, over-current, over-temperature, insulation detection, and high-voltage interlock protection. Pre-charge function is supported. Wake-up methods include ACC wake-up, A+ wake-up, and CHG_IGN wake-up. Dimensions are customized according to cell string count (16S/32S/48S). Passive balancing current is 50mA. Selected models can connect with APP, PC, IoT platforms, or displays to support vehicle monitoring and software expansion. Customized PCBA and integrated hardware-software development can be confirmed against cell chemistry, series count, current, protocol, and operating conditions.
