Does driving downhill recover all the energy used climbing a hill?
A route starts and ends at a similar elevation. Can its climbing and descending sections be ignored in an EV energy estimate?
EVVerity explains
A closer look
A round trip is not loss-free
Energy recovery is not a perfectly reversible process. Aerodynamic drag, tyres and conversion losses still matter, and available regeneration depends on the vehicle and conditions. Starting and finishing at the same height does not mean the hills had no effect.
Use comparable route data
For a regular hilly journey, observations from that route are more useful than assuming the climb and descent cancel exactly. Keep speed, weather and starting charge in the notes. Do not use stronger braking as a strategy to manufacture energy; drive safely and follow the vehicle’s guidance.
