Battery Management System (BMS）

Overcharge Protection

When the voltage of any single cell or whole battery pack is higher than the set value during the charging, and the duration reaches the limited time, the system enters the over charging protection state automatically, the charging MOS is turned off at the same time, and the battery cannot be charged. After the voltage of each cell and the whole battery pack drops below the cell overcharging recovery value, the over charging protection state is released. It can also be released by discharging to return to normal state.

Over discharge Protection

When the voltage of any single cell or whole battery pack is lower than the set value during discharging, and the duration reaches the limited time, the system enters the over discharge protection state, the discharge MOS is turned off, and the battery cannot be discharged. After the over discharge protection of the battery pack occurs, it can be released by charging the battery pack.

Over Temperature Protection

When the NTC detects the temperature of the battery cell surface is higher than the setting value of over temperature protection during charging and discharging, the management system enters the over temperature protection state, the charging or discharging MOS is turned off, and the battery pack cannot be charged or discharged in this state.

Low Temperature Protection

When the NTC detects that the temperature of the cell surface is lower than the setting value of low temperature protection during charging and discharging, the management system enters the low temperature protection state, the charging or discharging MOS is turned off, and the battery pack cannot be charged or discharged in this state.

c. Lock the parallel cable wires to the positive terminal of the battery pack first, then connect another end to the negative terminal.
d. Parallel communication cable to the RS485 port of the battery pack.
e. Connect positive terminals of the battery and the inverter with red power cable, and then connect negative terminals of both sides with black power cable. f. Connect both communication ports of the battery(RS485A/CAN) and the inverter(BMS port) with the communication cable, BMS ports of inverter have different definitions for some brands, please check the inverter manual.

Parallel communication cable connection Pin definition is as follows:

Battery & Inverter Connection

Connect the positive and negative cables of the battery to the positive and negative terminals of the DC input of the inverter, insert the RJ45 crystal plug at one end of the distributed inverter communication cable to the RS485 of the battery, and connect the other end to the BMS terminal of the inverter according to the defined line voltage, and then connect the battery to the inverter.

Dip Code Switch Definition and Setting

ADD switch is a 8-bit DIP switch to manually distribute the communication address of parallel batteries.
The BMS will only recognize the DIP address once it is reset, so please reset the BMS when the DIP address is changed (the BMS must be reset in the standby state). When the DIP address is 0, the battery is configured as the stand- alone working mode; when the DIP address is 1, the BMS is configured as the master working mode; when the DIP address is 2 to 6, the BMS is configured as the slave working mode.
Please refer to the table below to set the DIP switch for parallel connection of different batteries.
