Battery powered record of 75 MPH on AA cells!

by Sam Abuelsamid (RSS feed) on Aug 21st 2007 at 3:16PM

There hasn't been much good news recently for Panasonic on the automotive battery front with reports of delays to Toyota's plans to use lithium ion batteries in the next-generation Prius. However there was one recent bright spot when driver Takashi Sudo piloted the 84 lb. Oxyride racer to a record 75 mph. Unlike production type vehicles this one was powered by 192 AA batteries.

The driver loks really small. Wounder how fast this car could go with my 350 pound brother in law driving?

The human powered recumbent streamliner record is 81 mph.

I'm not too impressed Panasonic.

4: That's a very good point!

My first question though, was "why AA cells and not D cells?"

My next question is "What are they trying to prove? There are lots of full-sized electric cars out there that can go faster."

@ grimmex -

what they're trying to prove, of course, is that their AA batteries have high power density. It's a publicity stunt that has nothing to do with real-world cars and everything with brand image in consumer electronics applications.

Assuming they are pushing rechargeable technology... And I have no idea about Li-Ion...

They use AA instead of the larger C or D cells for a simple reason- the NIMH RECHARGEABLE C or D cell is typically just a AA wrapped in a larger package! Here is a link with some battery data for D cells showing the power of a D cell as 2200 maH: http://www.batteries.com/productprofile.asp?appid=212842 . The AA NiMH batteries are now in the 2850 mAH range.

Alkalines provide higher charge densities (more power per battery) and a higher voltage. A new AA alkaline is 1.5V and ~2900 mAH, a D cell has something like 18,000mAH!

I can not find these in stores.
I have found Duracell PowerPix at target, etc.
Cheaper than Lithium, better than regular alkaline.
