Checking Battery Condition With An Onboard Charger; Start Charge Cycle - Club Car 2008-2011 Maintenance And Service Manual

IQ PLUS CHARGER (ONBOARD)
3. Monitor the ammeter for the correct charge rate. The initial charge rate will vary from 15 to 19 amps,
depending upon the condition and depth of discharge of the batteries. Slight variations in the initial
charge rate may also result from AC line input voltages which are higher or lower than the nominal input
voltage. Higher AC line voltages increase the initial charge rate while lower AC line voltages reduce the
initial charge rate.
4. Monitor the ammeter for about 30 seconds. Under normal operating conditions (when the charger is on
and the batteries are discharged), one hour and at two hours into the charge cycle, the charger will shut
off in order to run a self-diagnostic program (ammeter will drop to zero). See following CAUTION and
NOTE.

CAUTION
• Do not connect an external charger to the receptacle of a vehicle equipped with an onboard
charger while the onboard charger is activated. Charging overload will damage the onboard
computer and may cause battery damage.
NOTE: Batteries should be put on charge at the end of each day even if the vehicle has been used for only
a short amount of time (even if for only 10 minutes).
When air temperatures fall below 65 °F (18.3 °C), batteries charged in unheated areas should be
placed on charge as soon as possible after use. Cold batteries require more time to fully charge.
New batteries will not deliver their full range until the vehicle has been driven and recharged from
20 to 50 times.
Vehicles should be restricted to 40 to 50 energy units of discharge between charges until the bat-
teries have been properly seasoned (20 to 50 charge cycles). For maximum battery life, Club Car
recommends that electric vehicles always be recharged after 40 to 50 energy units of discharge or
each night in order to avoid deep discharging the batteries; use the CDM (Communication Display
Module) (CC P/N 101831801). See Communication Display Module in the appropriate main-
tenance and service supplement.

CHECKING BATTERY CONDITION WITH AN ONBOARD CHARGER

Read DANGER, WARNING, and CAUTIONS beginning on page 9-3.
It is common practice for technicians to check the condition of a set of batteries after they have been charged
to ensure they have received a complete charge before the vehicle is used. With IQ Plus vehicles, this is not
necessary; the onboard computer controls and monitors the charge cycle. If any problem occurs during a
charge cycle, the battery warning light, located above the steering column in the center dash panel, will illu-
minate intermittently.
If the battery warning light is illuminated after a charge cycle, refer to the troubleshooting chart in the mainte-
nance and service manual appropriate for your battery charger. If you do not have this publication, contact
your Club Car representative. If the specified test procedures identify no problems, plug the AC cord into the
wall outlet and let it charge until the charger shuts off automatically. If a problem is found, correct it and then
charge the vehicle. Normal voltage near the end of a charge cycle should be approximately 59 to 63 volts DC.

START CHARGE CYCLE

1. Disconnect the AC plug from the wall outlet.
2. Wait 20 seconds, then reconnect the AC cord to the wall outlet. See following NOTE.
