Episode notes
Why EVs Are More Efficient
- EVs are more efficient than internal combustion vehicles because they avoid thermal losses and wasted heat.
- This efficiency translates into roughly three times lower energy consumption from battery to wheels for similar vehicles.
EV Efficiency Eases Grid Load
- Improved EV efficiency reduces the increase in electricity demand from vehicle electrification by half by 2050.
- This lowers the scale of grid expansion needed, easing integration of renewables and lowering costs.
Efficiency Enables Smaller Batteries
- Higher EV efficiency allows for smaller batteries to achieve the same range or longer range with same battery size.
- Battery size becomes a design choice that impacts cost and weight, influencing vehicle efficiency further.
