Re: Active cooling your leaf battery

Nissan could put a hose connection on the car. Arriving home with a hot battery, attach the garden hose and turn on the water to cool the battery. We have 55 deg. well water that would cool the battery down. Sorry for the strange idea...

Maybe it would be best to simply buy a vehicle that already has a TMS...
59,991 miles/12 bars/289 Gids/68.54 AHr/101% SOH/101.64% Hx 7May15 w/ new Lizard (barely made the warranty).
71,770 miles/12 bars/256 Gids/59.04 AHr/88% SOH/87.92% Hx 3Mar16 at lease return.

Now driving a 2016 Volt Premier. Model 3 reserved.

It might be worth trying this: spray the rear underside of the car with cold water for 5 minutes or so when the pack temp is high, and see if it drops noticeably. I'm considering trying a portable air conditioner blowing through the cooling tunnel if the new car won't fit in my garage.

^^^ I''m guessing the bottom will be all plastic(or a plastic shroud like on my '13) so spraying water wouldn't really help as the plastic shroud would be a pretty good thermal insulator :(
Your portable A/C unit would be a better choice if you could get the cool air to blow through the battery, might be kind of a hassle and wouldn't really help on the road, but would be an option.
Too bad Nissan doesn't have a fan that blows air through the battery when charging(at least QC'ing) like on at least one other EV they sell.....as TomT is fond of saying, we don't need no stinkin' TMS on our Leafs :?

I should have been more specific. There is (was?) an opening in the rear diffuser that one could use to spray water or air into the cooling channel. Can someone tell us if it is still there?
