Episode 20 – Efficiency in Electric Vehicles

Several listeners of the podcast have asked what are the main reasons for the differences in efficiency, i.e. why is there a difference in the efficiency published between Europe and the USA and others have been interested to know why there is such a large variation between seemingly similar cars. In answering these questions we cover the 5 main principle sources of efficiency gains in an electric vehicle:

1. Batteries and charging
2. Traction motor and power electronics
3. Ancillary systems
4. Aerodynamics
5. Vehicle weight
