Great 30 page summary on EV batteries by congress thinktank

This was put together by Congressional Research Service, a policy issues research arm of the US Congress, published in April 2013. I think for laymen like me this is a very informative, broad, and easy to understand introduction to the topic.

Very nice newbie overview.

 

[thankyouOB]

very cool and readable. longish.
very useful for folks who are science literate but not an EE.
i have a friend at Argon National Lab in Ill. he manages work groups as a physicist. his boss told him a year ago that there was an endless supply of funding if he wanted to switch to the battery group.

he stayed with his specialty. he is in his mid-60s and figures to be done soon.

I'm disappointed the federal government doesn't promote trailers for rent to extend the range when needed.

Perhaps because it is simply a problematic idea on so many fronts?

So problematic that it couldn't exist? http://www.evnut.com/rav_longranger.htm" onclick="window.open(this.href);return false;

Just because something exists does not necessarily make it a good idea... Among other issues, The Lone Ranger had terrible emissions by today's standards with that 500CC Kawasaki MC engine...

Just because something doesn't exit doesn't make it necessarily a bad idea. Emissions are easily solved with existing technology.

Thanks for Posting this. Contains a lot of Info I did not know.

When EVs have 10% market penetration this might become viable. More likely to become obsolete before it becomes a reasonable business model.

One thing I didn't know is that modern EV batteries "have safety considerations that mandate use of electronically controlled cooling systems." So automakers "build a computer-controlled, liquid thermal cooling and heating system to maintain battery temperatures in a safe range." I mean, I knew that many of them do, but I didn't realize it was mandated for safety. Longevity, perhaps, but safety? It sounds like I'd better stop driving my LEAF before my battery blows up.

[Yes, yes, I know there are different kinds of lithium batteries with different kinds of safety requirements, but I don't see any hint of that in the article, just a blanket statement.]
