How much can you typically gain with recuperation

[thinkbusiness]

I was wondering how much miles you can actually gain if you use recuperation instead of coasting.

on a typical 100 mile drive for instance.

My guess is minimal. Maybe a couple of miles.

If considering recuperation vs coasting as choices, coasting is more efficient. Always.

So how many miles do you gain using recuperation instead of coasting?
I don't know the magnitude, but I know the sign. It's negative.

Do people understand that the Taycan does energy recovery every time you touch the brake pedal to slow down even in coasting mode? It’s got one of the best blended braking systems out there.

To the question of coasting mode versus recuperation mode over 100 miles….

Coasting mode = when you remove pressure from the gas pedal, car coasts efficiently until you actually need to reduce your speed, then energy is recovered into the battery when you use the brakes to slow/stop. Manual “Recuperation” by brake pedal application.

Recuperation mode = as soon as you take pressure off the gas, the car immediately starts slowing and recovering energy into the battery even if you don’t need to slow down. You then may find yourself adding pressure back to the gas pedal to speed back up.

So in the recuperation scenario, unless you perfectly feather your pressure on the gas to never unnecessarily slow, you’re going to be transferring energy in both directions. Into speed, then back into battery energy, and then back into speed more often. Any time you make that conversion it’s not 100% efficient and there are losses. Thus far more potential to use more energy to cover the same physical distance.

Thus why coasting mode is usually more efficient and is recommended.

Recuperation is handy if you’re running a long downhill stretch and don’t want to ride the brakes as much, or running hard in twisties and want a bit more “engine braking” effect when you lift off corner to corner.

Impossible to answer accurately. Depends how you drive, terrain, air temp, battery state of charge etc.

2 types of recuperation available to you.

Braking recuperation - always on and available if you touch the brake pedal.

Overrun recuperation - manual or auto - provides limited recuperation when you lift off the throttle and let the electric motors provide "engine" braking.

Brake recuperation will have the potential to add more energy back into the battery depending on how hard you brake.

Overrun recuperation will add a few miles and brake recuperation a few miles more.

How does the “auto” recuperation setting work?

How does the “auto” recuperation setting work?

Auto recuperation is set by pushing the recuperation button on the steering wheel down for a few seconds until the letter A appears with the recuperation icon on the dashboard. Once activated, recuperation will engage when your foot is off the accelerator AND when another vehicle is detected in front of you. If you take your foot off the accelerator and no vehicle is in front of you, you'll simply coast.

Auto recuperation is awkward.
The car jerks and chucks around, especially when driving at slow speeds or in traffic.
I only use normal recuperation.

The answer is 7.6 miles per 100 miles driven.

How do I know? Because I just said so on the internet, so it must be true.

Recuperation is a overhyped energy transfer in EVs.

It never meant to recover 100% of energy used to move the car forward by converting its braking energy.

The idea of converting braking energy to electrical stems from the fact that each car must use braking at one point or other. Why waste that through friction and heat than converting to electrical energy to charge the battery. With recuperation on, car would spend more energy to move forward than recoup (when pedal is off) regardless that action was intended to stop the vehicle or not.

Downhill driving when gravity takeover, using braking to recoup that kinetic energy would be higher than car would use energy from its battery to move forward. During flat surface driving, simple physics wouldn't make braking recuperation as efficient.

I personally prefer auto mode which only acts upon 'seeing' vehicle in the front or based on road signs (inno drive). Which based on the situation I overwrite with pedal.

I don't use Auto recup as it is utterly unreliable in my daily use and can be 'dangerous' in use if not familiar with its behaviours.

Manual works just fine.

Imteresting. I’m using only auto-recup on my daily driving when coasting is not possible/has no sense and i use ordinary recup when i’m going downhill.

I like Auto as it keeps a nice space to the car in front of you and then just coast along.

I think the coast is more efficient overall as the process of converting\storing kinetic & electrons is less efficient than just rolling. I know porsche has ballparked 30% range is a result of their coasting+quick regen with the 800V setup.

If you want more range moving to narrower tires is a simple way. One trend my tire guy sees on Tesla & Porsche factory big rims is that the sidewalls are at high angles and the width of the tire is narrower than the rim - our 21's had that on the rear and is very odd - doesnt protect the rims at all with rubber! but in theory would give you a narrower tire contact spot. Not sure if they did that to squeeze some more range out. I went to the 19's for summer and winter for utility\durability and got more range + rim protection
