1. During hibernate mode
The hibernate state of the charger is a very low AC current draw charger mode.
This state starts automatically 24 hours after the start of the latest charge
operation. While in hibernate, the only thing the charger is doing is monitoring
time, and displaying the status of the charger with the LCD message display at
a dimmed brightness. 216 hours (9 days) after hibernate begins, the charger
will power backup and wake up the battery pack. There are 2 sub-states within
hibernate, assuming hibernate has not been interrupted, that prepare and
maintain the battery pack during long term storage.
Upon waking up from hibernate mode, the pack and charger will establish
CAN communications to determine the system status. If all is O
will initiate a discharge of the battery pack. The goal of this discharge is to
reduce the pack SOC from 100% to 40% within 30 days. This discharge is done
because the lithium battery pack capacity can be permanently reduced if stored
at too high of SOC for too long. When the battery pack reaches 40% SOC, it will
indicate that the discharge is completed by changing its state to Storage. The
charger will then go back into hibernate mode.
Every 10 days thereafter, the charger will power backup and monitor the status
of the battery pack. If the pack reaches too low of SOC (30%) the pack will
be recharged to 40% SOC.
To return the battery pack to 100% state of charge after hibernation, disconnect
the battery charger from the battery and connect the battery to the eFlex
machine. Turn the key switch to the S
process of the machine. Then, turn the key switch to the O
full shut down of the machine. Finally, connect the battery pack to the charger to
allow the battery pack to receive full charge.
