| flash 3 | 0.5S | 1.5S |
Note： The LED indicator alarm can be enabled or disabled through the host computer, and the factory default is enabled.
Buzzer action description
- In case of failure, it will beep for 0.25S every 1S;
- During protection, it will beep for 0.25S every 2S (except for overvoltage protection);
- When alarming, it will beep every 3S for 0.25S (except overvoltage alarm);
- The buzzer function can be enabled or disabled by the host computer, and the factory default isdisabled.
Key Description
- When the BMS is in the dormant state, press the button (3~6S) and release it, the protection board willbe activated, and the LED indicators will light up in sequence from “RUN” for 0.5 seconds.
- When the BMS is activated, press the button (3~6S) and release it, the protection board is put to sleep,and the LED indicators light up sequentially for 0.5 seconds from the lowest battery light.
- When the BMS is activated, press the button (6~10S) and release it, the protection board will be reset,and all the LED lights will light up at the same time for 1.5 seconds. After the BMS is reset, it still retains the parameters and functions set by the host computer. If it is necessary to restore the initial parameters, it can be achieved through the “restore default value” of the host computer, but the relevant operation records and stored data remain unchanged (such as power, cycle times, etc.). , protection records, etc
Sleep and wake up
- hibernate
When any of the following conditions are met, the system enters a low-power mode:
-
* The single or overall over-discharge protection has not been released within 30 seconds.- Release the button after pressing the button for 3 seconds.
- The minimum cell voltage is lower than the sleep voltage, and the duration reaches the sleep delaytime (at the same time, no communication, no protection, no balance, and no current are satisfied).
- The standby time is more than 24 hours (no communication, no charging and discharging, no mainspower).
- Forced shutdown through the host computer software.Before entering the sleep mode, make surethat the input terminal is not connected to an external voltage, otherwise it will not be able to enterthe low power consumption mode.
- wake
When the system is in low-power mode and meets any of the following conditions, the system will exit the low-power mode and enter the normal operation mode:
- Connect the charger, the output voltage of the charger must be greater than 48V.
- Press the button for 3S and release the button.
- Connect to the communication line and open the software of the upper computer (it enters the sleepstate due to over-discharge protection, this method cannot wake up the protection board).
Remarks:
After the single or overall over-discharge protection, it enters the low-power mode, wakes up regularly every 4 hours, and turns on the charge and discharge MOS. If it can be charged, it will exit the dormant state and enter normal charging; if it cannot be charged after 10 consecutive automatic wake-ups, it will no longer automatically wake up. When the system is defined as the end of charging, the recovery voltage is not reached after 2 days of standby (standby time setting value), and the charging is forced to resume until the end of charging again.
DIP switch settings
When the battery packs are used in parallel, different PACK can be distinguished by their hardware addresses, and the hardware address of each PACK in the entire battery stack is unique. The hardware addresses can be set in sequence through the DIP switches on the board. Refer to the following for the definition of the switches. surface

The routine maintenance of the battery part can be carried out by referring to the table
| Period | Item | Treatment measures |
|---|---|---|
| Per month | (Operating environment) | Keep away from heat sources and avoid |
direct sunlight
Visual inspection| If the appearance is damaged, leaked or deformed, the
faulty battery pack should be disconnected, photographed and replaced.
Each quarter| Clean appearance| Clean the exterior with a cotton cloth. Due to
the high voltage of the battery pack, care should be taken when cleaning.
Connection Status| ****
l Check the bolts at each terminal and retighten them if they are loose.
l If the temperature of the connection line exceeds 40°C (feeling hot), check the cause
Every half year| Voltage detection| l At the end of charging, measure and record the busbar voltage and the positive and negative terminal voltages of the battery pack. The voltages of the two are consistent. Otherwise, check whether the cable at the corresponding connection is faulty.
l In the first year, real-time data collection at the end of discharge was performed at least every six months.
l Beginning in the second year, on-site capacity determination will be conducted every three months. If a certain battery cell is frequently overcharged and over-discharged in the historical alarm information viewed through the RS232 interface, it means that the battery cell has touched the charging protection point and the discharging protection point for a long time. This situation may lead to
insufficient backup time, it is recommended to replace it in time
The final state of charge and discharge can be judged by the capacity light, refer to the definition of LED light capacity status light.
