high voltage battery-10

RJ TECH has successfully developed a new version Battery Management System (BMS) for lithium based batteries, which is designed that operates more efficiently and communicates with UART between master and slave modules and can communicate via CAN protocol with external devices.

Micro controller based control and protection equipment is designed that help to measure and monitor the voltage, temperature and current values of the batteries.

They protect the battery cells from the conditions such as over charge, over discharge, high current, high temperature.

BMS balances battery cell voltages during charging process with passive cell voltage balancing.

In addition to the main controller module in the BMS, slave controller modules have been added to provide high resolution voltage and temperature tracking.

A modular BMS has been devised which can be used in groups of batteries of different voltage values thanks to electrically isolated slave control modules.

Master and Slave BMS

CAN communication (optional)

GPS function (optional)

APP for checking battery data (Optional)

Voltage \current\temperature\short circuit protection

Real time dynamic calibration

Multi-method combination

High accuracy measurement of the cell voltage /temperature/pack current
