ELECTRIC VEHICLE - BATTERY CHARGER Charger Troubleshooting

CHARGER TROUBLESHOOTING
See General Warnings on page 1-1.
DANGER
• Do not touch any wire or component in the battery charger while AC power is present. Failure to
heed this warning will result in an electric shock.
WARNING
• Knowledge of battery charger wiring and component terminology is required before attempting any
repair. See The Charge Circuit on page 15-9.
• Prior to servicing the external charger, disconnect the DC plug from the vehicle charger receptacle
and the AC power supply cord from the wall outlet.
NUMBERING VEHICLES AND CHARGERS
Return the vehicles to the same charger each night if possible. If the vehicles are put in a storage facility at random
and a vehicle dies while in use and testing shows the batteries are sound, then the problem is most likely with the
charger. However, finding the problem charger may prove to be quite time consuming. Numbering the vehicles and
the chargers and returning each vehicle to its designated charger each night can significantly reduce the amount
of time spent troubleshooting a problem.
USB SERVICE PORT
NOTE: The triangular charge status light doubles as the USB light. Flashing green means data transfer from the USB
is occurring. Solid green means data transfer is complete.
Use the USB service port for charging algorithm updates, software updates and troubleshooting.
To use the port, pull the cover from the port and insert a USB flash drive.
To update charger: With update file already on flash drive, insert drive into charger and let charger find file and
update itself.
To download from charger: Insert an empty flash drive into charger and let charger write charge history file to it.
When finished, reinstall the cover.
INCOMING AC SERVICE
Make sure the incoming AC line service is sufficient. If circuit breakers are tripping, fuses blow during the night or the
charger does not give the required starting rate when sound batteries are put on charge, an AC line problem exists.
The electrical service to the vehicle storage facility should be sufficient to deliver adequate voltage and current to each
charger with all the chargers turned on. If not, consult your local power company or electrical contractor.
