Component Descriptions
Batteries
The vehicle uses six sealed lead acid batteries for the traction motor. There is also a small 12V 18Ah
accessory battery. The traction batteries store about 5, 5.5 or 9 kWh (depending on if the pack is 98,
105 or 140 AH) of useful energy Some battery tips:
• Always charge your batteries whenever you can.
• Never leave the vehicle in a discharged state. A discharged battery can freeze in cold weather
and sulfate at warmer temperatures. Both destroy the battery.
• If you continually discharge your batteries more than 90% your batteries may only last 200
charge cycles. If you recharge after using only 25% of the energy your batteries my last for as
many as 1000 charging cycles.
• Cold weather decreases energy storage significantly. Range will be severely limited below
freezing.
• Charge in a heated garage during cold weather.
• Consider adding 5 battery equalizers. They can be purchased at
http://www.evsource.com/tls_powercheq.php. This will also add considerable life to your
batteries as well as extend range.
• If even one battery is bad, all six must be replaced.
Battery Charger
Below are the two styles of charger. The Delta-Q and the BC2-7215B.
The BC2 requires a dedicated 20A circuit and the Delta-Q a dedicated 15A circuit. The charger is
responsible for charging the 6 battery traction pack.
Fusible Link
The final line of defense in protecting the traction battery pack is the main fusible link. It may blow
because:
1. You have a short in the car wiring.
2. Your motor controller, DC/DC converter or contactor(s) are bad.
3. You switch from driving at a high speed in one direction to trying to accelerate quickly in the
other direction. Always have the vehicle come to a complete stop before you change direction.
