But you rarely have to brake an EV though.

I’ve had two EV’s over the last 6 years, and I have to remember to occasionally hit the brakes to keep them from rusting.

One pedal driving is just money - saves power and is just much smoother over all than old school breaking. IMO.

[EForEndeavour]

I've never driven an EV. How do you approach stop signs and red lights other than braking? Is "engine braking" (regenerative braking?) strong enough to handle that big a fraction of slowing down in city traffic?

[GrooveSAN]

Based on my experience (electric motorbike), the regenerative breaks are super strong indeed. You can tweak their « force », but usually, the strongest level is the most comfortable - that you eventually keep all day long. It will cause you to full stop even on the steepest slopes.

Once you’re used to it, you dose your deceleration by focusing on how much you release the throttle.

And the only situations where you have to hit the breaks are the unexpected events - e.g., a car coming at the last moment and which you should give priority to.

An electric engine running in reverse is a battery charger, so yeah you run it in reverse and you slow down about as fast as you accelerate.

It doesn’t work completely like that obviously for reasons, but it does work like that for gentle accel/decel.

[dagmx]

You just let off the accelerator. They have tuneable deceleration curves for the regenerative braking.

Think of it like playing a console game. When you hold the right trigger, your car goes faster. When you let off of it, it naturally slows down. Unless you opt in to harder difficulties, most racing games don’t make you brake much.

Driving an EV is just like that. You only really brake for an immediate stop.

I have a Prius hybrid. It has an indicator when the brake pads are used. It's easy to slow down and stop without using the brakes about 95% of the time

[simne]

It depends. On new EVs (which formally designed as EV from scratch), motors and charger are usually powerful enough to exceed brakes.

On conversed, usual practice to limit torque of motor to be less than on ICE original, because of regulations (which exactly state, electric motor should not exceed ICE torque), and this mean, they are just not powerful enough for 100% regenerative braking.

From technical view, modern electric engine could easy exceed brakes.

I'm member of Ukrainian EV activists group, and we there mostly talk about conversions. Unfortunately, conversions are not so cool as new EVs, but to be honest I don't know details of other countries regulations, they could be less restrictive.

Some EVs also tie in the same detection devices used for adaptive cruise control to adjust regenerative braking. It can be configured to 'coast' in a manner similar to old-school automatic transmissions, but will apply regen braking when other vehicles are detected ahead. This lets me drive it sort of like a regular automatic when on the highway but get the added return of wattage when traffic gets heavier.

There's also one-pedal operation, akin to driving a golf cart. Where you feather the accelerator pedal to slow, and it will engage much more aggressive regen braking if you let off the accelerator pedal. Some folks like this. I do not. I still drive other ICE vehicles and find the transition between them too jarring for my liking.

[dunham]

In city traffic, I rarely have to break. It's basically running the motor backwards (putting a load on it) and dumping the energy back into the batteries. It's limited by how fast the batteries can accept a change, so it doesn't always work when it's very cold out. I'll have to brake when a light catches me by surprise, and I brake when backing down my steep driveway. (The car does stop before getting into the street, but it's going faster than I'm comfortable with when approaching the sidewalk.)

The regenerative breaking is applied as you let off the "gas" pedal. It's kind of like driving a stick, but slows you down faster.

[Spartan-S63]

From what I know, there are several settings of regenerative braking you can choose. The higher levels will bring the vehicle to a stop, while the lower ones won't. So it's user-configurable to a degree.

[jauntywundrkind]

Recently had to learn how to force a Prius to use the brakes, as the rotors were rusting up & starting to pit!

I could not get my partner to brake hard enough to really engage the brakes. They just would not do it, would not brake hard enough to actually use the real brakes, no matter the prompting & even knowing how critical it was that we start to de-rust these rotors.

What I found out is: if you put the car in neutral, there won't be regenerative braking, & the car will use the actual brakes. That's the only way I could get my partner to use the actual brakes.

[dzhiurgis]

I'm sometimes convinced Tesla's cameras identifies the stop line and stops itself exactly there. All I do is release the throttle pedal and it coasts there where it needs to be.

[bryanlarsen]

The engine can slow down the vehicle at roughly the same rate it can accelerate it. And if you have an EV that has a 3 second 0-60...

[WaxProlix]

Generally, yes. Usually there are settings for how much regen you want, but the term 1 pedal usually inies a regenerative brake strong enough to stop at stop signs or when exiting freeways.

[thejazzman]

It's a timing skill you rapidly develop. Switching models throws off your timing, so don't be surprised when you initially use the brakes more.

[k8sToGo]

Crusing is much more efficient than one pedal driving. So it does not save power at all.

[jameshart]

The control scheme has nothing to do with the efficiency of the car. Whether one pedal or two, it’s going to use the same power for the same acceleration/cruise/deceleration profile.

Unless you’re concerned about the energy usage in your ankle when maintaining pressure on the gas with your foot?

[Kirby64]

If you’re lifting off the throttle enough to activate regen braking, you would be applying the friction brakes in a car as well. Maintaining a steady speed is more efficient than varying speed, but if you have to vary speed then one pedal driving is superior in every way.

If your one pedal driving doesn’t save power, then I would suggest a driver mod.

[losvedir]

Are there any cars that "cruise" (by which I assume you mean maintain velocity without applying a pedal)? Non-EVs mostly sort of do so, they still slow down gradually. I'd be interested in trying a car that cruises indefinitely. Sort of an automatic, always on cruise control.

[dzhiurgis]

IIRC 10% more effective to be precise. The UX is worth the cost.
