On-off instruction

It can be switched on or off by pressing the button. In the shutdown state, press the button to turn on the device. When turned on, press and hold the button for more than 3 seconds to turn off the device

Communication specification

RS232
Bms can communicate with the upper computer through the RS232 interface, thereby monitoring various battery information, including battery voltage, current, temperature, status, and battery production information, with a defaultbaud rate of 9600bps.

CANBUS
The default communication speed for CAN communication is 250k.

RS485
There are two RS485 communication interfaces, one of which outputs two interfaces in parallel for viewing battery pack information, with a default baud rate of 115200. By setting the dial switch to set the communication address, it is possible to poll and query the data of all battery packs, with an address setting range of 0-15.

Dial switch settings
When multiple battery packs are used in parallel, the battery packs need to be set to different addresses through a dial switch for normal use. The following dial switch address table.

Wiring diagram

There are strict sequence requirements for the power-on of the protection plate. First weld B- , P-,B +, P +, and sequentially plug in the battery sampling line connector from low to high. After power-on, press the key to activate it. Load or charger can only be added after all connecting wires are installed.
When removing, unplug the charger or load First, remove the battery sampling line connector in sequence from high to low, and finally remove B +, P +,B-, P-
