POWERDRIVE CHARGER FEATURES
• Charge Interlock
:
PowerDrive battery charger DC plugs have three pins rather than two blades that most standard
charger plugs have. Two of these pins are the positive and negative leads as on standard chargers; the
third pin is a sensing lead that is the communication link between the charger and the onboard com-
puter. When the charger plug is plugged into the vehicle receptacle, the onboard computer locks out
the vehicle drive system. This prevents the possibility of driving the vehicle while the charger is plugged
in and potentially damaging the vehicle and charger.
• Long-Term Storage Charge:
PowerDrive chargers are designed to be left connected with AC power to the charger, during off-sea-
son or long-term storage. The onboard computer will automatically activate the charger every 15 days.
To return the vehicle to service, disconnect the DC cord from the vehicle, wait 15 seconds and plug the
DC cord back in.
See following WARNING.
The charger will activate. Allow the vehicle to complete
one full charge cycle before putting it into service.

WARNING
• The charger plug must be pulled slowly from the receptacle. Jerking or pulling the DC cord
out quickly could cause arcing and burning that could damage the plug and receptacle and
could cause batteries to explode.
BATTERY WARNING LIGHT
The 48-volt electric vehicle features a dash mounted battery warning light (above the steering column) that,
when the vehicle is in operation, indicates low battery voltage or, when the vehicle is being charged, indicates
a charging problem. The battery warning light is controlled by the onboard computer.
When the batteries receive an incomplete charge because 1) the DC power cord is disconnected, 2) AC
power to charger is interrupted, 3) automatic charger shut-off occurs after 16 hours of operation, or 4) charger
malfunctions, the warning light will indicate as follows:
•
The battery warning light will not illuminate if the charge is 90% or more complete. The onboard com-
puter will retain in memory the amount of charge needed to fully replenish the batteries and will com-
plete the charge during the next charge cycle.
•
When the charger DC cord is unplugged during a charge cycle, the battery warning light will illuminate
and remain illuminated for 10 seconds if the charge is less than 90% complete but the vehicle has
enough power for 30 minutes of operation. This will alert the fleet operator that the vehicle may be
used, but that it must be charged to completion as soon as possible.
•
The battery warning light will repeatedly illuminate for 10 seconds, at 4 second intervals, if the charger
times out at 16 hours and the batteries are not sufficiently charged. This indicates an abnormal charge
cycle. The charger and batteries should be checked by your Club Car distributor/dealer.
•
The battery warning light will repeatedly illuminate for 10 seconds, at 4 second intervals, during a
charge cycle (with the DC plug still connected) if AC power to the charger is interrupted. The light will
go out when AC power is restored.
