Good for high discharge rates (high peak power) and fast charges.

If you have ever seen those old Ford tv commercials, and the guy reaches up and pulls a little chain and a light bulb turns on. Ford has a Brighter Idea. cuhulin

The Hybrid Fords also use water cooling for the Hybrid electronics Nothing new...

Some people have water cooled computers.

has an article about submerging a computer in an aquariam/fish tank full of mineral oil, to help keep it cool. Cool Hand Luke. My boy Luke says he can eat fifty eggs, he can eat fifty eggs! cuhulin

Nothing new. The Cray-2 was cooled by liquid nitrogen back in the

1980's. And then there's the alcohol cooled computer. The web site no longer seems to be there, but they brought a 66Mhz 486 up to just shy of 1Ghz if memory serves.

Once in a while I get some auto parts stores snail mail flyers.Sometimes they have antifreeze advertized at a lower price than the regular price. cuhulin

You're a few years off on the Cray-2, and it was cooled by Fluorinert (which boils a lot higher tha nitrogen does).

Water cooling of batteries seems like an alarming thing to me, because it means the battery efficiency is so low that the battery is wasting energy as heat. Efficient machines don't get hot.

I understand heat losses in a PWM controller are inevitable and made worse by that fact that everyone wants to pack all the electronics into a tiny little space. But batteries?

Controllers get hot.. batteries get hot under hard use, but the heat/ effeciency loss is an order of magnitude less than what a regular car engine wastes. Well-to-wheels, a modern EV is appx 50% more effecient than a modern gas car. Ben

Heat is largely a simple fact of life of higher performance. In anything. If you design a machine that doesn't generate (perceptible to the touch let along none at all) heat, it's because you simply aren't using large amounts of power. What you're talking about is a misperception that was born during the steam age at the very birth of engines and before they were properly understood by the people making such arguments and before the laws of thermodynamics were proven/ /developed/known to anyone but physicists.. Without such impossible things as frictionless surfaces, perfect conductors and 100% efficient chemical reactions you simply won't get it.

Sure, but that's damning with faint praise. The gasoline engine is... pretty inefficient to say the least.

Don't all or most hybrid cars have some sort of battery cooling system anyway?
