Piezoelectric tires
« on: November 23, 2011, 01:39:53 AM »
Hi all,

This is my first post here and I am interested in what you think about this:

http://spie.org/x48202.xml?ArticleID=x48202

 I own electric car with lifepo4 batteries. Can go around 90 kilometers per charge but this would be awesome extension. My question is, could a tire like the one in article really extend the range of my car ?

Second part of question would be, is it hard to make this with right skilled people.

I have some funds I would be willing to crash into this VERY much, but the thing is I my self am not very skilled so any input on this matter would be highly appreciated.

Thanks,

sajas

I have been thinking about how the forces that occur inside the tire area could be a useful tool for extending the range of an electric car.
In the article link you sent, the Piezoelectric tire produced 4.7 watts.  With four tires on the car it would not even produce 20 watts.  I have a Chevy Bolt that has a range of 228 miles from a 60 kilowatt battery.  These tires would not extend the range very far for the money I would need to pay for four tires.  Maybe there is other ways to use the forces created in the tire that would produce a lot more electrical energy.  The problem is that weight, added resistance in the tire rotation created by these devices, maintenance and increased cost to the vehicle all need to be calculated into the equation of doing something like this.  There does seem that someone may have an idea taping into the forces that are going on inside of the tire that could increase the range of the vehicle enough without the issues I have described though a different technological approach to this challenge other than Piezoelectric tires.  Have you looked into shock absorbers that would generate electrical energy for the car?   

I think it is great that you are looking at ways to make products more efficient with new ways of doing things!

The german company intertronic gresser shows you "shock absorber" technology ,from their patent you will see ancient trials to introduce this method with dis-/advantages,disadvantage mainly financial,low weight cars do not
gain much energy !

Btw : 300 miles range by which average weight and velocity versus stated 228 miles per charge conditioning !?

Complete BS.
The energy which is generated by the piezos has to come from the car's motor... plus some losses.

This is the best I have received without the air conditioning or heater on.  BUT, I live in Wisconsin and drive to Minnesota and in the winter with the heater on I get about 160 miles on the coldest days.  So you are correct to correct me.  The overall mileage I have achieved over a two year period of time is 4 miles per kilowatt.  What do you think of instead of a sun roof I had solar panels on the roof of the car.  Again the car uses so much electrical power, It would take for ever to charge the car.  It would be a good backup for the battery going dead in a remote area.

 Thank you for pointing that out!  Again !,   I am new to this kind of thing

4 miles per KWh = 155,4 Watth per Kilometer average (all seasons) : average velocity ?

compared

68 Wh per Kilometer,included brake energy recuperation ( without 80 Wh/Km estimation)
by average 25 mph or 40 km-h " velocity"
 as Tesla 100D range record,without AC/heater or other unnecessary consumer !
