Interface Definition

RS485 and CAN interface

Communication description
RS232 communication
The BMS can communicate with the host computer through the RS232 interface, so as to monitor various information of the battery on the host computer side, including battery voltage, current, temperature, status, SOC, SOH and battery production information, etc. The default baud rate is 9600bps.

RS485 communication
With dual RS485 interface, you can view the information of PACK, the default baud rate is 9600bps. To communicate with the monitoring device through RS485, the monitoring device is used as the host to poll data according to the address, and the address setting range is 2~15.

Table 2 Description of capacity indication

Table 3 LED flashing description

Note: The LED indicator alarm can be enabled or disabled through the host computer, and the factory default is enabled.

Buzzer action description

1. In case of failure, it will beep for 0.25S every 1S;
2. During protection, it will beep for 0.25S every 2S (except for overvoltage protection);
3. When alarming, it will beep every 3S for 0.25S (except overvoltage alarm);
4. The buzzer function can be enabled or disabled by the host computer, and the factory default is disabled.

Key Description

1. When the BMS is in the dormant state, press the button (3~6S) and release it, the protection board will be activated, and the LED indicators will light up in sequence from “RUN” for 0.5 seconds.
2. 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.
3. 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:

1. The single or overall over-discharge protection has not been released within 30 seconds.
2. Release the button after pressing the button for 3 seconds.
3. The minimum cell voltage is lower than the sleep voltage, and the duration reaches the sleep delay time (at the same time, no communication, no protection, no balance, and no current are satisfied).
4. The standby time is more than 24 hours (no communication, no charging and discharging, no mains power).
5. Forced shutdown through the host computer software.Before entering the sleep mode, make sure that the input terminal is not connected to an external voltage, otherwise it will not be able to enter the 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:

1. Connect the charger, the output voltage of the charger must be greater than 48V.
2. Press the button for 3S and release the button.
3. Connect to the communication line and open the software of the upper computer (it enters the sleep state 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 

The final state of charge and discharge can be judged by the capacity light, refer to the definition of LED light capacity status light.

Packing List

Storage, maintenance and transportation

Storage

1. The battery pack is usually stored at a state of charge of 20% to 40% in a clean, dry, ventilated and rain-proof room with an ambient temperature of -5°C to 35°C and a relative humidity of not more than 75%, and should be placed flat. Pad height, not less than 100MM from the ground;
