Buzzer action description
Power on, buzzer ringing;
Shutoff sleep, buzzer short;
When short circuit protection, the buzzer calls every 2S, short circuit protection 3 lock, the buzzer no longer calls; the buzzer
function can be enabled or prohibited through the upper machine, the factory is prohibited by default;
When the buzzer function is prohibited, the buzzer does not work during the protection board alarm and protection (except for
short circuit and reverse connection protection);
Key instructions
When the BMS is dormant, the key press is greater than 1S and the protection board is activated.
When the BMS is working, pressing the key pressed for more than 3S and less than 6S, the BMS goes dormant.
When the BMS is working and the key press lasts longer than 6S, the protection plate is reset.
Sleep and wake up
1. Dormancy
To reduce the power consumption of the entire system, the system is dormant and enters hibernation mode when the following
conditions are met:
1) The single overrelease protection is still not lifted for 5 minutes (the time can be set).
2) The standby state duration reaches 24 hours (no communication, no charge and discharge, no charger access).
3) Open the composite button switch according to the operating rules.
4) By using the "forced hibernation" button of the upper computer computer, the protection board can be forcibly shut down
to enter the hibernation mode.
2. Wake-up function description
Combined with the actual situation, for the convenience of use, the system provides a variety of different ways of waking up:
1) Charging wake-up, access to the charger, the charger voltage is greater than 36V;
2) Keys wake up;
3) Communication wake up can be awakened through RS485-1, RS232 serial port and CAN communication; please note that the
battery is monomer or overall overput into dormant mode, not serial port;
Communication instructions
1. RS232 communication
The BMS can communicate with the upper computer computer through the RS232 interface to monitor various battery
information at the upper computer end, including battery voltage, current, temperature, status, SOC, SOH and battery production
information, with a default port rate of 9600bps.
2. RS485 communication
With a dual RS485 interface, you can view the information about the PACK, and the port rate defaults to 9,600 bps.If you
need to communicate with the monitoring equipment through RS485, the monitoring equipment as the host, poll the data
according to the address, the address setting range is 1~16.
3. Dial-up switch settings
When PACK is used in parallel, different PACK can be distinguished by setting the dialing switch on BMS to avoid setting the
same address. The definition of BMS dial switch refers to the following table.
