Example project

Electric buggy for educational use in vocational schools for automotive students. Possible to use track days in cross country tracks or in winter time when slippery.

Mechanics

  1. Steel tube frame one seat off road buggy
  2. rear wheel drive
  3. four wheel independent suspension
  4. battery under the bottom of the vehicle (under the seat).
  5. racing shock absorbers
  6. front and rear disc brakes

Electrical circuit

  1. stationary TC Charger 8kW for fast charging
  2. onboard 1kW charger
  3. DC/DC converter 72V - 12V
  4. brake light

Control and drives

  1. DC series exited motor
  2. Curtis controller 72V 500A
  3. curtis potbox for accelerator pedal

Monitoring instruments

  1. BMS123 battery cell monitoring system
  2. battery SOC state of charge gauge
  3. voltmeter
  4. ammeter

Driving

Helmet mandatory.Preferably on cross country race track or grass. Not for asphalt use because of the design of rear axle - no differential. The car cannot turn without one rear wheel slipping. Like in kart racing. Otherwise if there would be a differential the wehicle would spin one wheel on start and acceleration would suffer.

Maintenance

  1. Brake pads
  2. Suspension parts
  3. Chain lubrication
  4. every year check motor brush wear
  5. Battery capacity check
