Yes you use the brakes for quick stops.
You can coast, to do that you just keep your foot down enough to keep the regeneration from kicking in.
There's no free lunch. You don't recover meaningful energy by regenerating vs. coasting over the same distance. What you do recover is energy that would otherwise go into the air as heat in braking situations.
- jacquesm 9y agoThat could easily cause someone else to rear end you. Braking in excess of rolling should require the use of the brake pedal.
- rhino369 9y agoOr just trigger the break lights.
- jacquesm 9y agoYes, that would be the best solution.
- CalChris 9y agoIf someone rear ends you because you have B-mode or one pedal enabled then they're following way too close to begin with. Way too close and/or not paying attention at all. B-mode doesn't slam on the brakes. It engages regen to decelerate at perhaps a greater rate than rolling resistance.
- jacquesm 9y agoIt's the same as engaging the handbrake while driving. If someone rear ends you when you do that it is your fault, not theirs. The expectation is that if you reduce speed at a rate associated with braking that your brake lights should come on.
- CalChris 9y agoI strongly agree that the brake lights should come on in B-mode. That doesn't happen on the Leaf or on the Volt. That is however a different matter and it should be the law. But B-mode with brake lights is a fine idea.
- jessriedel 9y agoThanks. > You don't recover meaningful energy by regenerating vs. coasting over the same distance. In fact, you lose net energy if you regeneratively break and then accelerate (vs just coasting) because it's only 80% efficient. So if the "default" position of the pedal is to be braking, rather than coasting, I naively expect it to induce more braking followed by more acceleration, wasting net energy.
- greglindahl 9y agoYour expectation isn't true for the way I drive, at least. With one pedal driving, you don't really know if you're accelerating or braking, unless you're braking enough that your foot lifts from the pedal... or you look at the dashboard. I find that when traffic is heavy, I spend a lot of time slightly accelerating and slightly braking, while keeping the distance between my car and the one in front of me.
