No. | Function | Description |
1 | Dial switch | When PACK is used in parallel, different PACKs can be distinguished by setting the address through the 4-bit dial switch on BMS. The address should not be set to the same. |
2 | Key function | 1. When the BMS is in sleep state, press the button (3-6S) and release it. The protection board is activated, and the LED indicator lights up from "RUN" one by one for 0.5 seconds. 2. When the BMS is in active state, press the button (3-6S) and release it. The protection board will be put to sleep, and the LED indicator light will be lit sequentially from the lowest power light for 0.5 seconds. 3. When the BMS is in active state, press the button (6-10S) and release it. The protection board will be reset and all LED lights will light up simultaneously for 1.5 seconds. |
3 | communication interface | The 1RS485A/B connector allows multiple devices to be connected in parallel to increase the battery capacity. 2. The RS232 interface communicates with the upper computer, so that the battery information can be monitored through the upper computer. 3. RS485/CAN communication and inverter communication. |
4 | SOC estimation and display | It has SOC estimation function and displays the remaining power through 6 green LEDs. |
5 | status display | The operating status is displayed through a green LED display system. |
6 | A fault warning is displayed | A red LED display system shows a fault |
7 | SOH estimate | There is an SOH estimation function |
8 | Beep function | In case of fault, it will ring for 0.25S every 1S; When protection is in place, it will beep for 0.25S every 2s (except overvoltage protection); When an alarm is issued, it will sound for 0.25S every 3s (except for overpressure alarm); |
