BATTERY CHARGING
Observe all safety information in this section, safety
information listed at the beginning of this section, and
safety information in Section 1 of this manual.
Columbia electric vehicles are equipped with a solid state,
onboard, fully automatic, Delta-Q Battery Charger as standard
equipment. See Figure 9-3.
It is important to be aware of the differences and improvements
over prior chargers, which are explained in the Delta-Q Charger
Operating Instructions that accompany every vehicle.
Correct charging methods extend battery life and vehicle range
between charges. Before the first new vehicle use, completely
charge new batteries. Charging time is affected by age of
battery, condition of battery, state of discharge, temperature of
electrolyte, AC line voltage level, and other variables. Charging
time usually takes 12 hours. New batteries need up to four
hours more charging time than
“mature” batteries.
Always schedule enough charging time so that the charger
completes a full charge cycle. Opportunity charging is an
acceptable practice for use during a shift to extend the range,
but always allow for a full charge cycle at end of shift.
Limit the use of new batteries between charges for the first 15
– 20 cycles. New batteries have less capacity than batteries
which have been cycled.
Recharge batteries immediately after use. Leaving batteries in
a state of discharge will reduce there capacity and useful life.
Battery chargers are voltage specific; 24, 36 or 48 volts.
However, chargers can be programmed at the factory for
different types of batteries, as well as different brands and
capacities of batteries. Refer to Battery Brand Algorithms for
Charger Programming, See Table 1.
The lead-acid storage battery supplies electrical power through
the chemical action. This action is reversible, which means the
battery must be connected to a charger and have an electrical
current passed through it in the direction opposite to the
direction of discharge in order to restore the battery’s active
chemicals.
The Delta-Q Charger will not over charge batteries if left
plugged in.
CHARGER SAFETY INFORMATION
Do not attempt to charge a battery if it is frozen or if the
case is bulged excessively. Frozen batteries can
explode. Dispose of battery.
▪
Charge batteries in well ventilated area.
▪
Ventilation fans should be located at the highest point in
charging area. These fans should be able to exchange the
air 5x per hour. Consult a local HVAC engineer.
▪
Remove rings and watches prior to service. Only trained
technicians should repair or service the charger. Contact
Columbia for assistance.
▪
Replace worn, cut or damaged power cords or wires.
▪
Do not connect the power cord near fuels, grain dust,
solvents, thinners, or other flammables.
▪
Install surge arrestors on incoming AC power lines. This
protects from all but direct or close proximity lightening
strikes.
▪
Do not cover charger cabinet cooling fins. This protects the
charger from overheating.
▪
Make sure all battery and charger connections are clean
and tight. This prevents overheating and arcing at the
terminal. Replace as necessary.
▪
Disconnect negative (-) cable first to avoid crossing
terminals that would create a spark.
NOTICE: When using ordinary automotive chargers,
there is the possibility of overcharging and damaging
the cells.
