Goodyear BH03 Concept Tire

The Goodyear Tire & Rubber Company introduced the BH03, a radical concept tire at the 2015 Geneva International Motor Show that directly effects the plug-in electric car and hybrid markets.

This tire generates electricity through both static and dynamic actions through materials that transform the energy created by heat when it flexes as it rolls during normal driving conditions as well as heat from light when it is stationary. The materials used optimize the tire’s electricity generation capabilities as well as its rolling resistance.

Components of this concept includes:

  • Ultra black texture to absorb heat from light
  • Thermo-/piezoelectric material
  • Structure cooling system
  • Heat absorbing tread

Automotive tires have been treated both as a commodity of price at one end and one of performance at the other. It is almost certain that such a concept will be met with two reactions. The first reaction to such a concept might be that the cost could never justify the energy saved. The second however, would ask what value one would place on this new type of range extender.

The EV market has only just begun. This technology has the potential to significantly contribute to the of future of the EV automotive sector. This new approach of extending range just might gain some traction. No word on the amount of energy that might be generated.

Goodyear Concept Tires Offer a Glimpse of the Future…Visionary tire technologies showcased at Geneva Motor Show

GENEVA, Switzerland, March 3, 2015 — Two groundbreaking concept tires unveiled by The Goodyear Tire & Rubber Company at this week’s 85th Geneva International Motor Show could radically change the role of car tires in the future.

Though the two tires are concept products, the futuristic technologies stretch the imagination and provide a glimpse of what practical innovations may be on the horizon.

The first concept – named “BHO3” – offers the possibility of charging the batteries of electric cars by transforming the heat generated by the rolling tire into electrical energy. The second concept – named “Triple Tube” – contains three tubes that adjust tire inflation pressure in response to changing road conditions, delivering new levels of performance and versatility.

“These concept tires reimagine the role that tires may play in the future,” said Joe Zekoski, Goodyear’s senior vice president and chief technical officer. “We envision a future in which our products become more integrated with the vehicle and the consumer, more environmentally friendly and more versatile.”

Additional details on the two concept tires:

BHO3
This tire generates electricity through the action of materials in the tire that capture and transform the energy created by heat when it flexes as it rolls during normal driving conditions. The materials used would optimize the tire’s electricity generation capabilities as well as its rolling resistance.

As demand for electric cars grows, this technology has the potential to significantly contribute to the solution of future mobility challenges. This visionary tire technology could eliminate the vehicle-range anxiety motorists may have with electric cars.

TRIPLE TUBE
This tire features three internal tubes within the tire. Tubes are located beneath the tread and near the inboard and outboard shoulders of the tire as well as the center. The tire relies on an internal pump that moves air from the main air chamber to the three individual air chambers, or tubes. The tire automatically adjusts – on its own – to three different positions based on road conditions.

. The Eco/Safety position – with maximum inflation in all three tubes – offers reduced rolling resistance.

. The Sporty position – with reduced inflation within the inboard shoulder tube – gives drivers dry handling through an optimized contact patch.

. The Wet Traction position – with maximized inflation in the center tube – provides high aquaplaning resistance through a raised tread in the center of the tire.

Although these tires are future concepts, Zekoski says they represent an essential aspect of Goodyear’s innovation strategy, instilling a forward-looking, market-back mindset in the company’s research and development teams.

“It is more important than ever for us to stay firmly rooted in our market-back innovation process, which calls on us to focus on, and anticipate, the rapidly evolving needs of our customers,” said Zekoski.

Goodyear is one of the world’s largest tire companies. It employs approximately 67,000 people and manufactures its products in 50 facilities in 22 countries around the world. Its two Innovation Centers in Akron, Ohio and Colmar-Berg, Luxembourg strive to develop state-of-the-art products and services that set the technology and performance standard for the industry.

My question is how much power to you get back. Such as does it add three miles of range to a Mitsubishi i-miev or ten or 20 miles to the i-miev or leaf?

I highly doubt that you would get evan half a mile. It’s a ridiculous idea, even more stupid than puting solar PV’s on a car.

The Toyota Mirai looks like Einstein in comparison.

PV’s on a car are a great idea, the little 12V panel on my leaf will mean the 12v battery will last much longer and is never flat even if I leave the car for a few weeks whilst on holiday, I wish it ran a small fan on hot days to take some of the heat out of the cabin. If there was 200-300W on the roof it could give me an extra 10km after a day parked in the sun, which is great if it means you can switch your car to 80% charge and extend the life of the battery. As a primary charging system on a car pv isn’t great but if nothing else it gives you a little extra space on your roof for more pv.

You’re not going to get 300 watts out of a solar panel throughout the day. On the summer solstice day, you’ll get 280 or so watts at peak radiance (around 11am-1pm), but you’re lucky to get 1/20th of that at 4-5pm. So you *may* get 1-2kWh on that summer solstice, but throughout the the year, you’d probably be lucky to get 1kWh, which is barely enough for around 4 miles (6 km), for a roof that is entirely covered in solar cells. More likely than not, you’ll get < 2-3 miles throughout the year.

+1. As a maintainer for the 12v the cells on the LEAF are great, I have suggested the exhaust fan several times on consumer surveys.

The tires look cool. But I suspect it is a total waste. The amount of power generated would probably be so small as to be useless. We’re probably dealing with miliwatts, or watts at best. Electric cars need kilowatts to be useful.

To push a car down the road at interstate speeds takes 20-30kW. That energy eventually has to turn into heat. Whether it be air friction or the friction between the tires and the road. I’m curious what percentage of that heat is imparted to the tires (and quickly cooled by surrounding air which is moving past the treads at 2x the vehicle speed). How much energy is on the table to be recovered and what % of that is thought to be convertible back to electricity by the piezos?

I like the concept of the variable response functionality of the tire for different driving conditions. And on a Tesla Model S, could this generation process add perhaps 3-5% additional range on a road trip or more ?

There is a LOT of dynamic force going on at each tire, so that energy potential could reclaim more than milliwatts it seems to me.

You’d probably be better off with low rolling resistance tires, vs. ones that use the resistance and try to turn it back into electricity.

You can only lower the friction so much before you start to affect braking and steering. The point of tires after all is to create that friction.

The dynamic tubes seem to be more to this point. They can shape the tires to offer less friction when you don’t need it and more when you do.

The rolling resistance of tires doesn’t come from friction with the road, or at least very little of it does. Rolling resistance from tires comes mostly from the mechanical action of each part of the tire flexing under the weight of the car as that part of the tire rolls to the bottom, then flexing again as it rolls on up and the tension is released.

This is also why you can improve mileage by making sure your tires are fully inflated. Tires with more pressure don’t flex as much as underinflated tires.

You’d need some standard that allowed different tire makers to fit / transfer power / communicate with the EV…

Assuming there was any useful energy return to justify doing it…

This is just too silly to deserve real consideration. The cost of tire replacement is already a major part of the maintenance cost for EVs; making the tires much more expensive with this added tech would make that problem even worse. And wouldn’t it also make the problem of disposal of worn-out tires even worse?

This was a very disapointing introduction… Couldn’t they have spun the tires and have it run a 60 watt light bulb or something?

If they haven’t figured out yet how to get the piezo-electric crystals’ energy out to a pair of wires they are being a bit premature in announcing this Great Technology Advance.

As other’s mentioned, does the tire cost more than the value of the juice it generates?

I think you lot are looking at this from entirely the wrong angle.
Ask not what your tyre can do for you, but how many tyres you need to get what you want.
Just add more hubs and tyres…
I wonder how many tyres you’d need to be totally self sufficient power wise? 🙂
