Figure 2-2:
The modules must be connected from the
positive terminal of one module to the negative
terminal of the next. The one positive and one
negative terminal remaining on the modules are
the main terminals. The voltage at the main
terminals is 48V nominal.
When battery modules are connected in series,
the voltage of the system is added (i.e. 48 volts)
and the capacity of the modules not added. The
capacity of the series string is equal to the
capacity of one module. In fact, the capacity of
the series string is actually equal to the module
with the least capacity. However, because the
voltage is four times higher, the power and
energy of the pack is four times that of one
module.
As the capacity of the battery is reduced by the
various factors, the power of the battery is
normally not effected. The energy (power used
over time) is reduced however. This means that
no loss of speed, acceleration, or feel of power
will be experienced when a battery pack’s
capacity is reduced. A battery pack with only 15
Ah capacity will have the same power as one
with 48 Ah capacity when both are fully charged.
What will be noticed is a reduction in the range
of the vehicle.
Battery Charger
The FunRunner has an on-board battery charger
located at the rear of the vehicle just in front of
the rear bumper. See Figure 2-3. The function
of the charger is to replenish the used energy
from the battery pack.
Figure 2-3:
The charger receives its power from a 110 VAC
outlet when a cord is plugged into the charger
input connector located in the front of the rear
body panel below the seat. The AC power is
converted to DC and conditioned to the proper
voltage and current output levels to charge the
battery. It will take the charger about 7-8 hours
to restore a battery pack from fully discharged to
fully charged.
Located on the top of the battery charger are
one green and one red LED. See Figure 2-4.
During charging, the red LED is illuminated.
When the battery pack reaches a full charge, the
green LED will come on and the red LED will go
out. These LED indicators are not visible unless
the trunk basket panel is removed. The battery
charge gauge on the instrument panel cluster is
the indicator normally used for state of charge
reference.
Figure 2-4:
The battery charger is designed to never
overcharge or overheat the batteries due to
prolonged charging. Leaving the charger
plugged in will allow it to maintain a full charge
