Lithium Battery Pack Charger - Toro Greensmaster eFlex 1800 Service Manual

Lithium Battery Pack Charger

The lithium battery pack charger (Fig. 65) is used to
charge the nominal 53 volt (42V to 64V @ 100% state
of charge), 35Ah lithium ion battery pack that is used to
power the eFlex. The charger communicates via CAN
with the battery management system (BMS) located
within the lithium battery pack. Refer to the eFlex Opera-
tor's Manual, Lithium Battery Pack Charger Operator's
Manual and Lithium Battery Pack Charger Operation in
this chapter for additional information about the eFlex
battery charger.
NOTE: It is strongly recommended that the charger be
connected to the battery pack, plugged into a wall outlet
and turned ON whenever the machine is not in use.
The LED's and LCD message display on the charger
should identify charger status during normal operation.
If the LED's and LCD display do not illuminate when the
charger is connected to the power supply with the power
switch turned ON, make sure that the AC power supply
is available for the charger. Also, consider that the char-
ger fuse located in the fuse tray under the charger power
switch may be faulty.
The charger LCD message display may indicate a prob-
lem with either the charger or the battery pack during
charger operation. 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 charger output
cord from the battery pack, disconnect charger power
cord from the outlet and wait for a minute to allow com-
plete charger and battery shutdown. Then, correctly
connect the battery pack charger and restart the charg-
ing 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 from the
charger LCD display and contact your Toro Distributor
for assistance.
With the exception of the battery charger fuse, power
supply cord and labels, there are no consumer service-
able parts on or in the lithium battery pack charger. If a
charger is inoperative and fuse and power supply cord
are not faulty, charger replacement may be necessary.
