- :> factor would be introduced by regenerative braking?
- :
- :negative reduction!! Or are you one of those free-energy fanatics who believe
- :that you can get more energy out of a process than you put in?
- :
- :Stop and go driving will require MORE energy, not less.
- :
-
- slight misunderstanding i think. stop and go driving with
- regenrative braking will require less energy than the same
- stop and go driving without regenerative braking.
-
- I think you will find that the energy losses due to braking
- are pretty small relative to the constant speed drag energy
- though, so regenerative braking will not make a dramatic
- difference to the range of the vehicle. ( unless its a mail truck.. )
