This is our the 4th generation high voltage bms.It's an overall bms solution, that is to say,You don't need professional technology to install our high-voltage BMS to form a complete battery system.
Our high voltage BMS has complete battery charge and discharge control logic and balance function between batteries. We can also set various parameters of the system according to the actual needs of customers to ensure the stability, reliability and efficient performance of the system.
Our integrated BMS has cheap, easy to install, stable, efficient features, welcome agents, distributors to establish cooperation relationship with us!
GCE BMS uses the resistor circuit to balance the cell. The cell voltage of the battery pack reaches 3.5V and the voltage of the cell is higher than the lowest single-segment voltage of 50mV, or the cell voltage exceeds 3.65V to turn on the equalization function. Time (except for overcharge and full charge) equalization stops.
Make the BMS in the shutdown state and complete the connection with the BMS. After the BMS is assembled, turn the micro disconnect switch on the chassis to "on", then press the start button (DC start), and the BMS will enter the self-test.If the self-test is normal, you can hear the sound of the contactor closing, the green light on the chassis is on for a long time (it will flash if there is external communication), and the start is completed.
After the system starts and starts normally, turn the micro disconnect switch to "off" to turn the BMS into shutdown / transport status. If the BMS is not used for a long time, the BMS must be in this state.
