Product introduction
The lithium battery safety protection module has charging, discharging, temperature, and overcurrent protection functions, which
can effectively protect the lithium battery. And has a passive energy consumption balance function
Lithium battery lighting management module has the functions of battery metering and external I2C communication, Real-time digital output voltage, current,temperature, SOC and other data in line with the SBS protocol.
The lithium battery management system BMS has a complete safety
protection function, a power metering function, I2C communication management function, passive balance management function, and
real-time voltage, current Digital output of temperature and SOC, SOH and other data
Passive equilibrium is achieved through
certain The algorithm drives the independent corresponding small discharge circuit to consume unbalanced energy to achieve the
purpose of equilibrium.
The communication module is divided into a computer host computer communication box and a mobile phone APP
Bluetooth module and RS458 CAN module. Tool to convert BMS data
