In this lesson, students will begin to explore the potential and challenges related to using photovoltaics to supplement the power needed to charge batteries in BEVs. Students will test a variety of wiring options related to series and parallel wiring. Once students have grasped the basics, they will measure the surface area of a passenger vehicle and calculate the approximate power that could be produced by integrated PV modules into the structure of the vehicle. Students will use these calculations to determine each of the following:

  • The added mileage between plug-in charges that could be achieved.
  • The amount of time required to charge the vehicle using only the PV modules within the structure of the car.
  • The PV array size required to match the charge time boasted by Tesla Supercharger Stations.
