Leaf cooling blanket(?): A guess -- 1 gallon a day could ward off the damaging heat in a parking lot. So a gravity feed (might require low pressure electric pump) 5 gallon tank would be good for the work week , with a temp sensor to start gravity flow to the blanket. Prolly feed water to the...

Perhaps an "entrepreneurial Phoenician" could come up with an evaporative cooling blanket for their electric pony ... a poor man's TMS? http://ak1.ostkcdn.com/images/products/L12998478.jpg" onclick="window.open(this.href);return false; Strap it under the battery pack and drive over a...

... and so it's not hard to imagine that a Leaf parked at a mall in Phoenix on a "nice" summer day could be sitting in a bath of 140 + deg air. Well into the "red bar" zone of the Leaf's battery temp gauge. Kind of makes you wonder about the details of the Leaf battery temp monitoring system...

Might be interesting to get a thermometer and check the "usual suspects". I.e. -- do you (occasionally) park your car outside in the driveway? Does the driveway catch a lot of afternoon sun (sloped to the west)? I live in your area and can think of a couple times I have been astounded by the...

Nothing to add really except, .... everyone seems to be thinking capacity loss is a result of a repetitive conditon/repetitive event ..... any chance it's just a one time event? i.e. one overheat to above x temperature (west sloping concrete parking spot, almost no air circulation, adjacent...

Ok, got it. That seals up this question (just like the battery box).

Not to keep beating this horse, but..... "slightly pressurized" would mean the "pressure" (presumably air) is being introduced into the battery box from somewhere. /"battery" as mentioned from the service manual -- means they are talking about the whole battery enclosure (?) // plus, in...

Ok. Thanks. Wow. Hard to believe there's not some sort of air circulation in there.

Can someone tell me if the Leaf controls the amount of air flow to the battery? i.e. if you've been tooling around in town at 20 mph avg in the no wind city environment and then jump up on the highway at 65 mph plus a headwind at 32 deg F does the Leaf have a way of closing off air flow to the...

Well, perhaps the masked man can rig up a cable that'll take the CAN bus info to an iphone (maybe even a RAM mounted ipad), then ... your friend could write a program that displays a proper SOC on the apple device .... or better yet, he writes a program that does the whole shebang! /but...

Klapauzius, A likely scenario could be that the Leaf's range calculations were originally based on lower speed suburban runaround at 48 deg. Then, the car was put into a higher speed (I5) commute at 32 deg. As the evening progressed -- high(er) speeds, thicker air and cold soaking took their...

One factor in accurate range estimation that I haven't seen mentioned yet .... wind. If the first 1/2 of your drive is with a tailwind and then the drive home is with a headwind, this might cause your range estimation to be off. While I don't have an electric car, I do obsess over mpg with a...

The biggest day to day changes in efficiency (assuming I'm driving in a consistent fashion): 1. Temperature (dense air causing extra drag) 2. Winds (anything more than about 45 deg off the tail will hurt efficiency -- i.e. winds hurt more than they help) 3. Traffic These factors are...

Ok. Thanks. And from what I've read, the degradation won't necessarily be linear? I'm thinking the drop from 80% to 60% will happen quicker than the drop from 100% to 80% ?

AndyH, (or anyone else with an opinion), ... I will likely drive my Leaf (assuming I go ahead with the purchase) not more than about 8,000 miles per year and charge to 80%. So I'm thinking the calender will take my battery out before cycles do. Any guess as to how long (in years) before a...

Yaaaaaay!! Finally, an answer. Thanks EVD.

Aren't those the lyrics to a Van Halen song? :o (maybe that's the "new" Van Halen)

Yes, I was thinking the duration for the Volt's battery discharge duration will be less than 1/2 that of the Leaf. But then the ICE fires up and all that heat will have to be shielded away from the battery. And then there's the "mini-cycling" of the battery during CS operation which would...

So.... Let's say you live in Phoenix. On a typical July afternoon you are going to drive around the 'burbs' for an hour in a Volt/Leaf. What would be the typical/max battery temps you'd see in each car?

Will CAN bus info finally and definitively tell what the total capacity of the pack is ?? /inquiring minds want to know
