Does one-pedal drive strain electric motors/gear train?

[BlackGT PE]

I’ve been using one-pedal recently on my GTPE and I’ve recently wondered if it strains the motor more… I found this thread below and it suggests it does (see attached). Would like your opinions/knowledge! Thanks!

No. It uses just as much regen when you use the brake pedal in 2 pedal mode.

That user doesn't know how the vehicle works... Regen on an electric vehicle isn't the same thing as engine braking on an ICE.

Regardless of your drive mode, the car will always use regen before applying the friction brakes - 1pd just makes that happen more aggressively without having to touch the brake pedal, but outside of 1pd, when you start pushing the brake pedal, regen is always used first. If you drove the same course at the same speed, using 1pd and just the pedal, they'd have the same total regeneration.

The answer to "where do the forces go?" is "into the battery". The inverter drive for the motor doesn't care what direction current is flowing - if the car is called to slow down, current flows from the motor to the battery. If there is a call to accelerate, then current flows from the battery to the motor. All the same as far as the drivetrain is concerned.

The battery/motor/transmission is designed to transfer energy. The energy transfer during braking is less than max acceleration. Only the direction is different.

Man, that snippet cracks me up. Gears and bearings are loaded more heavily? Uhhhhhh…. Not unless reversing the flow of electricity without using the brakes creates a greater acceleration than flooring the go pedal. ?‍?

On a related note, I hear if you don’t drive your car then your tires don’t wear as quickly!

For the OP, our car uses blended braking so the mode you are in doesn’t affect how much your car uses regen or friction brakes. The mode just changes which “button” slows you down.

Hitting the brake pedal (button #1) in 2 pedal mode has the same effect as taking your foot off the accelerator pedal (button #2).

Tesla owners with over 150k on original brake pads from the factory would probably disagree that 1PD strains electric motor/gear. Hybrid and plug-in hybrid owners with double the mileage would probably disagree with that as well.

Tesla's with over 150k with original brake pads from the factory would probably disagree that 1PD strains electric motor/gear. Hybrid and plug-in hybrid owners with double the mileage would probably disagree with that as well.

To be fair, not using the brake pads would actually put a mark in the column for putting that strain on the motor/gear.

But bottom line is that the car is designed for it. Like was mentioned- it’s less strain than accelerating.

So confidently wrong. If it weren't for the date stamp I'd think that was an AI-generated response mid-hallucination.

If you drove the same course at the same speed, using 1pd and just the pedal, they'd have the same total regeneration.

Perhaps I’m being daft, but how can this be true if we are told that 1PD delivers more efficiency/range than 2PD?

Because that statement is also false. 1PD and 2PD have the same efficiency unless you are braking harder in 2PD than 1PD.

Thank you all for your expertise! I was watching YouTube videos on regen breaking but wasn’t finding anything specific to wear on motor. I am glad it turns out the Chevy Bolt forum discussion turned out to be garbage! Thanks again!

Perhaps if Ford actually put a power/regen meter on the console of ALL their EVs, people would realize that it regens in every mode, including 2 pedal. There's about 50% wasted space in the center console and it blows my mind that they couldn't think of anything relevant to put there. I love the car but the software is absurdly poor.

You are being told that by people who don’t understand how the blended braking works in the Mach E.

They think that hitting the brake pedal = friction brakes. That isn’t true.

Other manufacturers (like Tesla) require 1PD for regenerative braking which also confuses the matter.

Agreed, the giant speedo in the center wastes so much space. I hate it
