How to start

What can you control about your car?
  • The four things that you can realistically realistically control
  • Electrical Electrical efficiency 
  • Losses due to electrical electrical resistance 
  • Losses due to poor gearing
  • Weight 
  • Rolling friction friction
  •  Aerodynamic drag

 Possible Order of Decisions
  • Find your motor For example, 
  • example, an ETEK motor runs at 48 volts z Plan for sufficient batteries to operate motor at the optimum efficiency A 48v motor will require require four 12volt 
  • Batteries,two 24 volt batteries, etc. [The number of batteries batteries will coordinate coordinate with your frame] 
  • Plan your solar array so that it can efficiently efficiently charge your batteries batteries A 48v motor will require require at least 52 volts coming in from your solar array and producing producing approximately approximately 2.5 amps. 
  • How many amps do you need to meet your power needs?
