How to start

What can you control about your car?

  • The four things that you can really control

    • Electrical efficiency

    • Losses due to electrical electrical resistance

    • Losses due to poor gearing

    • Weight

    • Rolling friction

    • Aerodynamic drag

Possible Order of Decisions

  • Find your motor. For example:

    • an ETEK motor runs at 48 volts. Plan for sufficient batteries to operate motor at the optimum efficiency A 48v motor will require require four 12volts.

  • Batteries,two 24 volt batteries, etc. [The number of batteries will coop with your frame]

  • Plan your solar array so that, it can efficiently charge your batteries batteries. A 48v motor will require at least 52 volts coming in from your solar array and producing approximately 15 amps.

  • How many amps do you need to meet your power settings?
