From Transport Evolved (nice work again):

...at yesterday’s international launch event for the Nissan e-NV200 electric van — a vehicle which shares the same 24 kilowatt-hour lithium-ion battery pack and 80 kilowatt electric motor found in the Nissan LEAF — we noticed something rather interesting which makes us think Nissan might be rethinking its policy on battery heating and cooling.

The e-NV200, unlike the Nissan LEAF, has a small air conditioner built into its battery pack.
...

Nissan wouldn’t go into too many details with us, but it looks as if the e-NV200 can send warm or cold coolant from the van’s main HVAC system to the small integral radiator within the battery box. Air is then drawn over the radiator from outside and is then cooled or heated as needed to keep the battery pack and battery box at optimum temperature.

Interesting. Lots of the talk about large format cells was they didn't need thermal management like small cylindrical cells, saving weight, complexity, efficiency. Guess maybe they need it after all...

Scanning the article it appears they are more densely packed in for the van than the LEAF, which may be part of the reasoning behind this.

Surely if they are more densely packed, then it's not the same battery pack as the Leaf? It might be the same 24KWh rating, but not the same pack...

This is a good point.

Does Nissan e-NV200 Show Change of Policy on Battery Heating, Cooling?

GREAT article thanks will read more .

After getting home and put on charge the e-nv200 after the odd rapid noticed that there is noise fan sound I presume the battery after a few rapids then put on home charger the fan kicks in . but all good as pack does keep pritty cool but then again we do very little rapid on leaf or the e-nv200 van . but all good hear.

The Berlingo Electrique has water jackets in all the batteries. (i have a 2003 model) It can't heat the batteries but it can cool them as the coolant flows to a conventional looking radiator with electric fan at the front via an electric pump.
