Some more views of the IDS (see it drive itself...at ~3mph) starting at ~3:40) with CG's narration:

Yes, but only if you can keep the system voltage the same, which means 96 cells in series. So, yes, 40 kWh works out if the 60-kWh version really has cells in triplets. (Nissan does NOT have the granularity available to Tesla, which uses the 18650-sized cells.)edatoakrun said:Couldn't another configuration of the new cells allow a lower kWh (and dimensionally smaller-if required) replacement pack for 2011-15 LEAFs, If Nissan wants to produce one?
Not to me. At the end of the day, the best solution is a pack which does not have very much self-heating and which can handle the normal climate variations.asimba2 said:The apparent lack of battery thermal management is a disappointment.
asimba2 said:I used to feel that way but after watching the thread on how the 2015s with the Lizard pack are 'holding up,' I am very much unimpressed. My battery pack averages 94 degrees in summer months (as read from the car's three battery sensors) with some days at well over 110 degrees without ever having used DCQC. Those kinds of temperatures are not conducive to long battery life, and thus I won't be buying an EV without some kind of TMS.

There's nothing inherently virtuous about active thermal management, and there are definite drawbacks. It depends on the needs of the cells. The new chemistry may or may not require it. The lower internal resistance is a good sign; at least in terms of heat from charging/discharging.
An ideal EV would not have, nor need, active thermal management. It consumes energy from the battery that is better-used for motion and complicates the life of the owner. One thing I'm quite happy with regarding LEAF is that I can leave it sit for weeks, and the pack still has nearly the same range remaining as when I left. Such cannot be said for a Tesla, for example.
Not for me, I like things to be simple with less maintenance. If the physics and technology support a path to batteries that don't need a thermal management system, it would be like driving a gas car without the need for a radiator or coolant pump. It should be researched and developed because it will benefit everyone in the long run. Even if requires just passive forced air cooling, that would be about as complicated as I would want the battery technology.asimba2 said:The apparent lack of battery thermal management is a disappointment.
No - it is almost the same size as the current battery.DaveinOlyWA said:60 kwh in a package roughly 30-40% larger than the original is pretty impressive (guessing by pix on size differences. could be 50-60% larger)
No - it is just a hatch. Are you confusing this with Gripz ?but IDS is a SUV/CUV right? not so much LEAF II. with a 60 kwh option, an SUV/mini van is a no brainer I would think. the product shown looks more like what infiniti would be putting out more than Nissan but either way, when the tide rises...
