The DepowerBT management system is connected to the active equalizer via Bluetooth to monitor the battery status, The status of each single cell in the power battery pack is detected to determine the status of the entire battery system, and corresponding control adjustments and strategy implementation are made to the power battery system according to their status, so as to realize the charge and discharge management of the power lithium battery system and each single cell to ensure the safe and stable operation of the power battery system. 1. Display real-time voltage, current, power, internal resistance and other parameter values, and display them in the form of instrument panels and numbers; 2.Record battery data using a chart timeline. Easy to use 3. Each data comparison of the battery cell, the voltage difference. Maximum voltage cell Minimum voltage cell. And the display of cell balance 4. Cell temperature warning. Real-time alarm for over temperature, short circuit, over voltage, under voltage 5. Display the real-time voltage and alarm status of all single batteries. If the reported parameters trigger the alarm value or protection value, an alarm will be prompted; 6. Detect the voltage, charge and discharge current, temperature and other information of each battery, and realize the battery overcharge, over discharge, disconnection, low voltage charging prohibition, discharge overcurrent, short circuit, charge overcurrent and overtemperature protection functions
