2022 Chevy Bolt EUV Brake Energy Recapture Test- Mt. Washington New Hampshire

We took a Chevy Bolt Electric utility Vehicle to the highest peak in the Northeast to test one-pedal driving and brake energy regeneration. The Bolt EUV passed with flying colors.

One of the best parts of living electric is the ability to use one-pedal driving and to recoup braking energy via electric regeneration (technically just generation). The all-new 2022 Chevrolet Bolt has a nifty one-pedal driving button to help make capturing the most energy very easy. Chevy puts the button in plain sight near the gear selector and it is locking, meaning you don’t have to hit it again when you reenter the vehicle.

We joined a GM-sponsored Chevy Bolt Electric Utility Vehicle (EUV) event in New Hampshire this week to learn every detail possible about the new Bolt EUV. We have a more comprehensive report coming once our images are ready for publication, but wanted to highlight the brake energy recapture in this story.

One Pedal Driving - What Is It?
One pedal driving is a drive mode where the EV you are in uses its electric motors aggressively to recapture energy when you slow down. You rarely need the brake the system works so seamlessly. If you prefer the old-fashioned feeling of a car that glides to a stop, the Bolt EUV has that mode too.

One Pedal Driving - Why Bother?
By enabling one-pedal driving you can capture more of the energy that would otherwise be lost to your friction brakes. And the amount is meaningful. We started up Mt. Washington with 248 miles of range estimated by the vehicle. Of course, that would be for normal driving. Gaining six thousand feet of elevation in eight miles is anything but normal. During our drive up, the Bolt’s awesome torque was on full display. We enabled Sport Mode and the Bolt EUV pulled like a coal-powered train. One of which still runs up and down the mountain every day. And boy can you smell the pollution from it at the top.

At the top of the mountain, our range estimation display was 190 miles. Heading down, we barely used the friction brakes, tapping them just twice when we were surprised by other drivers. When we got to the bottom, our range estimation displayed was 233 miles. All the way down we put energy back into our battery. There are signs all the way up and all the way down warning you to use low gear and to stop to allow your brakes to cool. And the signs are no joke. We could smell the friction brakes of the old-school gas-powered SUV ahead of us all the way down.

Here is a quick TikTok video summarizing our trip.

The amount of energy wasted by vehicles that don’t capture brake energy is staggering. Hybrids, plug-in hybrids, and battery-electric vehicles all use this method to earn their amazing MPGe ratings from the EPA.

So, sure the energy savings are great. But what’s even better is not boiling the fluid in your car’s lousy CVT, smelling your brake pads fry, or feeling your brake rotors warp.

EVs have so many advantages they are hard to count. One of the biggest is the ability to put energy back into the vehicle’s energy storage unit (battery). When you shop for your next EV, be sure the one you check out has one pedal driving and a locking switch so you don’t have to enable it every time you drive.

Regeneration is one of the features that I really loved about my Chevy Volts, and still enjoy on my Cadillac ELR EREV plug in. I have steering wheel paddles to activate regen on demand, and I can put the shifter into L, which increases regen and activates when you let off the "gas" pedal. I live on a hill, so I gain between 4-7 miles of range just using the brakes before I get on the freeway. Of course I lose that added range and a bit more when I drive back up, but I would have lost more energy if I didn't have regen. Most of the time I don't use L or the regen paddles because just stepping on the brakes automatically adds power back into the traction battery. The extra bonus is that because most of the car's braking is done by regen my actual brakes are hardly used (but still always available by pressing the brake pedal harder). So effectively the life of the brake pads are extended to hundreds of thousands of miles, maybe even to the life of the car. Regen is one of the hidden benefits of modern EVs. It makes me feel good when I know that my braking energy is being converted back automatically into electricity, as opposed to normal brakes which always just lose that potential energy, converting it into heat and brake pad wear.
