I've owned a Model S for 2 years and 65k miles, I'm really familiar with regenerative braking. Let's say your charging for a long trip to 100% and live at to top of a large grade.
In that case you will have to rely on your brakes 100%. I know this because I make a 300mi roundtrip that exactly matches that profile nearly every week and for the first 5 miles I have no regenerative braking.
From a safety standard you have to match the braking system of an equally equiped ICE.
- Robotbeat 9y agoIf you live on the top of a tall hill, there's no reason to charge to 100% no matter how long your trip will be as you'll charge up to 100% on the way down. All you have to do from a safety perspective is ensure there's charge overhead. I own a Volt and there's a "mountain mode" setting for just this purpose, plus in the Volt there's always some headroom in the battery that is held in reserve by the system.

Cool, your volt can fallback on its ICE and always leave a reserve a Tesla/Leaf/Bolt just isn't the same. You're saying I need to plan my charge down to the watt? What happens when I hit 100% with a mile of hill left to go?
