Battery Specifications

Working Mode

3.1. Basic Mode
3.1.1. Charging Mode
The BMS turns on the charging MOSFET for charging when it detects an external charging voltage of ≥48V, and the cell voltage and temperature are within the chargeable range. When the charging current reaches the effective charging current, it enters the charging mode. Both charging and discharging MOSFETs are on in charge mode.
3.1.2. Discharging Mode
The BMS enters the discharge mode when it detects that the load is connected and the cell voltage and temperature are within the dischargeable range and the discharge current reaches the effective discharge current.
3.1.3. Standby Mode
When neither of the above two modes is met, it enters standby mode.
3.1.4. Hibernation Mode
The BMS will enter sleep (shutdown) mode after a specific time of standby, or when the battery triggers undervoltage protection, or when the key is executed to shutdown or when the upper computer executes the shutdown command mode.
The wake-up conditions of hibernation mode:

1. Make charging to activation;
2. Press the button to power on.

3.2. Description of Buzzer
Buzzer function can be enabled or disabled via the upper computer, factory default is disabled.
3.3. Description of Reset Button
When the BMS is dormant, press the button for 1S and then release it, the protection board will be activated and the LED will light up from “L4” for 0.5 seconds.
When the BMS is active, press the button for 3S and then release it, the board will be dormant and the LED will light up from “RUN” for 0.5 seconds.
3.4. Dormancy and Activation
3.4.1. Dormancy
The system will enter low-power mode when any of the following conditions are met.

1. Single cell undervoltage protection or overall undervoltage protection is not released within 30 minutes.
2. Press the button for 3 seconds and then release the button.
3. The minimum individual voltage is lower than the sleep setting voltage (default value 3150mV) and the duration reaches the sleep delay time (default value 1440 minutes), and there is no communication and no charging/discharging in meanwhile.
4. Forced shutdown via the upper computer software.

Note: Before entering hibernation, make sure that no external voltage is connected to the P-terminus, otherwise it will not be able to enter the low-power mode.
3.4.2. Activation
When the system is in low-power mode and any of the following conditions are met, the system will exit low-power mode and enter normal operation mode.

1. Connect to the charger, the charger output voltage should be greater than or equal to 48V.
2. Press the button for 1S, after releasing the button.

LED Indicator Description

4.1. LED Indicator Description
Four green capacity indicators, one red alarm indicator, one green operation indicator

SOC				ALM	RUN

4. 2 SOC Capacity Indicator

4.3 Status Indicator

4.4. Flash Instruction of LED Indicators

Communication

With RS485 and CAN interface, which supports communicating with multiple machines in parallel and with the upper computer. RS485 baud rate is 19200, CAN baud rate is 500K.
RS485 INTERFACE

The multi-unit parallel bus connections are shown in the following figure.  

Assignment of ID Addresses

When performing parallel communication operation of multiple machines, you need to configure the dialing address of each PACK first. When the BMS is configured for stand-alone operation, and the dialing address can be any address; when the BMS is configured for cascade operation mode, the slave dialing address is selected from 1 to 31, and the host dialing address is selected from 32 or 48 according to the inverter brand.
You can enter the address code of the master or slave battery in the system parameters of the upper computer to detect and communicate.

Upper Computer Software Introduction

Enable the monitoring software, select the communication interface of the corresponding device, select the corresponding baud rate, and finally click “Open Serial Interface” to communicate with BMS and get the basic parameters. You can switch the version in Chinese or English in help center  After the BMS communicates with the upper computer, you can monitor the basic parameters and status of the battery in real time. These information include battery voltage, current, SOC, SOH, cycle count, battery temperature, alarm status, protection status, etc.You can view the real-time data storage of the BMS and export as excel tables. When monitoring multiple packs, you need to set the start and end address of packs manually, you can check and comparethe data of each pack. And you can also export as excel table.  Basic parameters 1.Click “Read All” when enter for the first time.
