Smart Li-Battery BMS Module
Model：BMSP48100B2
Smart Li-Battery BMS Module is divided into two parts, BMU and BDC, BMU (Battery Management Unit) realizes voltage and temperature monitoring of single cell, SOC calculation, operation logic strategy control, parameter setting, external communication, etc. BDC (Bidirectional Direct Current Converter) is a system that connects the battery pack with the battery pack. BDC (Bidirectional Direct Current Converter) is a bi-directional DC converter circuit between the battery pack and the main circuit of the communication backup power supply, which is used to carry out the functions of constant current, constant voltage charging and discharging as well as standby and protection of the battery.
This Smart Li-Battery BMS Module has entered mass production and is widely used in mobile communication base station backup battery management systems, home battery management systems, medium and large server backup battery management, etc.
Basic introduction.
This Smart Li-Battery BMS Module is suitable for lithium iron phosphate battery communication backup power supply, can provide over-charge, over-discharge, over-current, over-temperature, under-temperature, short-circuit and reverse connection protection for the battery pack, and also provide voltage equalization in the charging process; it can be used to realize reliable multi-group parallel connection and communicate with the upper computer through the CAN bus or RS485, and the maximum number of parallel connection groups is 32 groups. Parameter configuration, data monitoring and software upgrading can be carried out on the software of the upper computer. Intelligent Li-ion BMS is compatible with 15-series and 16-series Li-ion battery packs.
