2.5 Sleep and Wake Up Function Description
1 ） Wake up
When the system is in low power consumption mode and any of the following
conditions are met, the system will exit the low power consumption mode and enter the
normal operation mode: When the charger is connected, the output voltage of the
charger must be greater than 48 V.
Operate the power switch button to restart the battery.
Connect to the communication line and open the software of the upper computer
(It enters the sleep state due to over-discharge protection, and this method cannot
wake up the protection board).
2 ） Hibernate
When any of the following conditions is met, the system enters low power
consumption mode:
The individual or overall over-discharge protection has not been released within 3
minutes.
The minimum cell voltage is lower than the sleep voltage, and the duration reaches
the sleep delay time (At the same time, no communication and no current are
satisfied).
Standby time more than 1 hour (configurable) (no communication, no charge and
discharge, no charger access).
Forced shutdown through the host computer software.
Before entering the sleep mode, make sure that the input terminal is not connected
to external voltage or external communication, otherwise it will not be able to enter the
low-power sleep mode.
