4.5 BATTERY CHARGERS
All current production Columbia 24/36/48 volt electric vehicles are built with new solid state on-board, fully
automatic high-frequency, programmable battery charger as standard equipment. Two different charging
systems are used. Vehicles can be equipped with a DELTA Q Charging System or a PRO Charging
System.
4.6 DELTA-Q BATTERY CHARGING
The Delta Q charge status can be found in two locations. On
the Delta Q face and on a remote multicolored LED (Figure 4-
6B). This LED and descriptive label will located near the
Charger Receptacle.
NOTICE:
Do not cover the charger cabinet or cooling fins with clothing, blankets, or other
material. Fins provide ventilation and prevent overheating.
Do not disassemble the charger. There are no serviceable components.
4.6.1 CHARGER OPERATING INSTRUCTIONS
Connect the supplied power cord to the vehicle charger receptacle and to a properly grounded wall outlet.
Charger start and charge time is automatic. The Yellow AC power LED (Fig. 4.6A No. 1) should remain
illuminated while the Charger is plugged into an AC source. The remote LED will be flashing short green.
If these LED
’s are not lit, before replacing Charger, recheck the AC connection and the AC source fuse or
breaker. If this fails to correct the problem, contact your Columbia Dealer for assistance.
Charger will automatically turn on and conduct a short self-test and battery pack test. All Delta Q
LED’s
will flash in sequence and then a trickle current will be applied to batteries until a minimum voltage is
reached. In Figure 4.6A No. 3 indicates the Bar Graph and No. 2 indicates the lowest LED. Three (3)
amperes is displayed as the lowest LED on the Bar Graph.
If the batteries meet the minimum voltage requirements of the Charger, signifying they are serviceable
(chargeable), the Charger enters the bulk charging (higher amperage-constant current) stage. The Delta
Q
Bar Graph LED’s indicate the electrical current being delivered to the batteries as the Charger moves
through its automatic charge profile. The length of charge time at each level will vary due to battery size
and battery charge depletion. The remote LED will be flashing short green.
NOTICE:
If the batteries are excessively discharged, the Delta-Q Charger will not be able to
charge the complete set of batteries. The Delta-Q RED FAULT LED (Fig. 4.6A No. 6) and the
remote LED will be flashing red. (See Section 4.6.2 Red Light Charger Error Codes). It will then
be necessary to follow the Special Charging for Excessively Discharged Batteries, Section 4.6.
When the Yellow 80% LED (Fig 4.6A No. 4) is lit, the Charger has completed the bulk stage and the
batteries are at approximately 80% state of charge. The 80% LED remains on as the last 20% of charge
is returned to the batteries in the second phase (constant voltage phase). At this time the remote LED will
flash long green.
NOTICE:
You can terminate charging at this point if necessary. The vehicle can be used, but
completing the charge cycle is highly recommended.
