And now we have a damning report in Wired that Nissan has decided not to include active thermal management in their battery pack.

That may not mean much to you if you don't know EVs, but it means that you could have terrible battery performance. Meaning unhappy surprises during very cold weather, like getting 50 miles of range instead of 100. Like getting stranded on the highway in 20 degree weather. The BMW MiniE test program underway now has demonstrated how badly unmanaged batteries can fail.

Here's what a GM manager had to say: “Thermal management [with lithium manganese batteries] has bookend issues to manage: minimized power at low temperatures and life reduction at high exposure to higher temperatures.” Those battery packs are expensive for a reason.

The charge port on the left is actually a "fast charge" connector, designed to inhale power faster than the J1772 can (limited to 120/240 VAC power). I don't think there's a standard for that yet so it may be propietary.

Nissan appears to have been generous with themselves on stating the 100 mile range, having used the "LA4" cycle to calculate it. The LA4 cycle is essentially a low-speed city driving profile, with hardly any highway speed driving. Actual range will likely be much shorter than 100 miles. Literally, your mileage may vary!

Nissan announced their pricing of the Leaf this week, and by most analyses it's a game changer.

Supposedly the audio there is worth a listen too.

A few notes relayed from an insider:

In Atlanta, two Nissan dealers will have Leaf specialists on-staff (not sure if that's mechanics or sales): Nalley Nissan in Decatur and Capitol City Nissan in Chamblee.

The car will have an "ECO" mode that applies more aggressive braking regen; this will require a more active right foot but will result in even better performance in city driving.

The car will launch with a 3.3 kW charger; either 2011 or 2012 will then also offer a 6.6 kW charger option, which will halve the charging time.
