It is also quite apparent she drives with zero regards for energy management. The energy usage gauge is prominently displayed in the dash, for similar reasons that you use a fuel gauge. If you are at all concerned that your range may be questionable for a leg, then it is quite trivial to drive more efficiently. The author seems to not care about this at all and wants to drive wastefully. This is fine, but it takes away a lot of weight when whinging about range and poor planning.
- arkh 8y agoIf you want range but don't care about speed, just use a bike.
- hndamien 8y agoSpeed is pretty irrelevant. It’s actually acceleration and deceleration that matters.
- davidgould 8y agoThis is pretty much backwards. Energy use per distance goes up as the square of the speed. Acceleration uses energy too, but deceleration recaptures most of it. The tricks to really increase range are to keep speed moderate, follow a safe but close distance behind a large vehicle, and speed up and slow down gently.
- hndamien 8y ago“Speed up and slow down gently” - ie acceleration and deceleration.
- davidgould 8y agoIndeed, the resistance losses in an electric motor increase as the square of the current, torque increases linearly with current, so running higher current to produce more acceleration or deceleration is less efficient. But, I^2 resistance is not a large effect compared to the losses from air resistance at high speeds. That is, slowing down from 75 to 65 will have more effect on range than how quickly you accelerate to 75.
