Hibernate
The hibernate state of the charger is a very low AC cur-
rent draw charger mode. This state starts automatically
24 hours after the start of the latest charge operation.
While in hibernate, the o nly thing the charger is doing is
monitoring time, and displaying the status ofthe charger
with the LCD message display at a dimmed brightness.
216 hours (nine days) after hibernate begins, the char-
ger will power b ack up and wake up the battery pack.
There are 2 sub--states within hibernate, assuming hi-
bernate 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 deter-
mine system status. If all is OK, the charger will initiate
a discharge of the battery pack. The goal of this dis-
charge is to reduce the pack SOC from 100% to 40%
within 30 days. This discharge is done because the lithi-
um battery pack capacity can be permanently reduced
if stored at too high of SOC for too long. When the bat-
tery pack reaches 40% SOC, it will indicate that the dis-
charge is completed by changing it’s state to
”STORAGE”. The c harger will then go back into hiber-
nate mode.
Every ten (10) days thereafter, the charger will power
back up and monitor the battery pack’s status. If the
pack reaches too low of SOC (30%) the pack will be re-
chargedto40%SOC.
To return the battery pack to 100% state of charge after
hibernation, disconnect battery charger from battery
and connect battery to eFlex machine. Turn key switch
to START and allow full start up process of machine.
Then, turn switch to OFF and allow full shut down of ma-
chine. Finally, reconnect battery pack to charger to allow
battery pack to receive full charge.

Charger Fault Codes
During the battery pack charging operation, the charger
may identify a problem with either the charger or the bat-
tery pack. If a fault is determined, the fault will be dis-
played in the charger LCD message display. The LCD
message will identify either a charger or pack fault, a
fault identificationcodeand a fault code description (Fig.
10).
Should there be charging operation issues due to a fault
with the charger or battery pack, a first step to remedy
the issue would be to turn the battery charger power
switch to OFF, disconnect c harger output cord from the
battery pack, disconnect charger power cord from the
outlet and wait for a minute to allow complete charger
and battery shutdown. Then, correctly connect the bat-
tery pack charger and restart the charging operation to
see if operation has returned to normal. Some faults will
be reset during the restart and will then allow normal
charger operation. If a fault continues to occur, make
sure to record the fault information and contact your
Toro Distributor for assistance.
