  29. Electric carsWhat do we learn from these cars? • performance is not an issue (except range) • electric motors do not constrain vehicle design • no conventional design • market niches • energy storage is the main problem • charging is a constrain • several technical solutions for charging (including range extenders and battery replacement)

  30. Electric carsHow to improve? • energy storage • better batteries • supercapacitors • intensive regenerative braking • energy control • efficient control of load • efficient charging • system capable of absorbing extreme power (regenerative braking)

  31. Electric carsHow to improve? • “in vehicle” energy production (extended range, fuel cells) • high efficient ICE • cheap fuel cells runing on liquid fuel • weight • lighter energy storage devices • lighter construction (materials, manufacturing processes) • energy storage vs in vehicle energy production • powertrain design solutions • motors with capability for extreme power (regenerative braking) • motor-in-wheel units

  32. Electric carsWhat are the challenges? • batteries with better power density than supercapacitors • supercapacitors with better energy storage than batteries • minimizing recharging time without straining the grid • very efficient “in vehicle” energy production • powertrain moving parts exclusively within the wheels • compact, efficient, powerfull and resistant motor-in-wheels • eco-friendly materials intensive use • body and frame design

  33. thank you
