4.3 SLEEP AND WAKE UP
SLEEP
When any of the following conditions is met, the battery enters the low-power mode:
• Undervoltage protection is not released within 90 seconds.
• The reset button is pressed for 3 seconds and then released.
• The lowest cell voltage is lower than the sleep voltage, and the duration of such
state reaches the sleep delay time (while meeting the requirements of no
communication, no protection, no equilibrium, and no current).
• Standby mode lasts for more than 24 hours (no communication, no charge or
discharge, no mains power, minimum cell voltage is less than 3.2 V).
• Forced shutdown from the EMS Tools level.
Before entering the sleep mode, make sure no charger is connected. Otherwise, it will
not be able to enter the low-power mode.
WAKE UP
When the system is in the low-power mode, and any of the following conditions is met,
the system will exit the low-power mode and enter the normal operation mode:
• A charger is connected and the output voltage of the charger is greater than 51.2 V.
• The reset button is pressed for 3 seconds and then released.
• The communication line is connected and the EMS Tools opened (if the battery
enters sleep mode due to over-release protection, this method cannot wake up the
battery).
NOTE:
If there are other batteries in the output state in parallel application scenario, the
current battery cannot be set to sleep through the reset button, because it will be
charged and awakened by other batteries with normal output.

19
• The power switch is used.
NOTICE
After battery over-discharge protection is activated, the battery enters the low-power
mode, wakes up every 4 hours, and switches to charging or discharging. If it can be
charged, it will exit the sleep mode and enters the normal charging slate. If the single
cell voltage is below 2.5 V the battery will no longer auto wake up.
