The weight of the battery won’t affect the energy needed to keep a car at a steady highway speed. The energy needed is just whatever losses come from friction, air resistance, etc
- thinkmassive 3y agoThe weight of the battery is related to the amount of friction.
- Magiccupcake 3y agoAt 70mph most energy is lost to wind resistance. EVs are also heavier, which increases rolling resistance on the tires. This lead to the formulation of stiffer tires for EVs to counteract that effect.
