Lithium Battery Pack Charger Operation
The lithium battery pack charger (Fig. 3) is used to
charge the nominal 53 volt (42V to 64V @ 100% state
of charge) 35Ah Lithium 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. The charger shall re-
spond to the CAN messaging issued by the BMS which
will communicate, among other things, the immediate
voltage and current needs of the battery pack. The char-
ger is intended to be used indoors only and can be left
connected to the target battery pack indefinitely.
Power input to the charger is provided by an AC power
supply cord. Power supply for the charger can be either
110/120 VAC or 220/240 VAC. The output cord from
charger to battery pack includes a positive cable, a neg-
ative cable, a wake up wire and CAN--bus cables. Make
sure that the correct power supply and output cords are
used for the lithium battery pack charger.
The charger is equipped with three (3) LED’s to indicate
the charger is ON, the battery is CHARGING and the
battery is READY (fully charged). Additionally, the LCD
message display on the charger can be used to monitor
the charging process.
NOTE: Referto your eFlex Operator’s Manual and Lith-
ium Battery Pack Charger Operator’s Manual for addi-
tional 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 battery pack charging operation is fully automated.
When regular charging occurs to ready the battery pack
for in season mowing, battery charging states include
startup, ramp up, charging, cell balance and standby.
When the battery pack is in storage, t he charger also
provides a hibernate state. The LCD message display
on the front of the charger will identify the present state
of the charger.
The charger will automaticallyshut down (exit any active
state and return to the startup state) if the output cord
from the charger to the battery pack is un--plugged or if
the AC power to the charger is interrupted (e.g. circuit
breaker tripped).
