4.2 Boot and sleep mode
Sleep mode: the battery will be in sleep mode if any of the following conditions are met
1) The battery or battery pack over discharge protection lasts for 30 seconds and is not
released.
2) Press the power on / off button for 3 seconds and release.
3) The minimum voltage of the battery is lower than the "sleep voltage" setting in the
setting, without charging and discharging.
4) Standby for more than 24 hours without charging and discharging.
5) Switch to the upper computer for sleep manually.
Wake up: the battery will exit sleep mode if any of the following conditions are met
1) Charger is plugged in;The charger voltage is greater than 48V.
2) Press the power on / off button for 3 seconds and release.
3) Plug in the communication cable and open the upper computer software (not
available if it is under over discharge protection).
Note: if over discharge protection is enabled, the battery will be in sleep mode. The
battery will wake up automatically every 4 hours and turn on the charge / discharge MOS. If
charging is available, the battery will be charged, otherwise it will return to sleep mode. If it
has been awakened 10 times but cannot be charged, the battery will not wake up again
automatically.
4.3 Communication area
Picture 4 Communication interface diagram
1. RS232: BMS can communicate with upper computer through RS232 interface, so as to
monitor various information of battery, including battery voltage, current,temperature,
status and battery production information, etc. the default baud rate is 9600bps.
2. RS485: with dual RS485 interface, you can view the information of pack. The default
baud rate is 9600bps.If it is necessary to communicate with the monitoring equipment
through RS485, the monitoring equipment is used as the host, polling data according to
the address, and the address setting range is 1 ~ 15.
3. CAN: CAN communication, baud rate 9600bps.
4. DCT：dry contact interface.
