Nissan unveils more data in the battery capacity loss controversy, saying that the culprit is total driving distance, not heat, and that the battery packs are behaving as expected considering the heavy use.

The controversy over Nissan Leaf battery pack capacity loss is getting deeper, following a statement from Nissan published through Green Car Reports, and a response published by EV Owner Tony Williams writing on InsideEV's. Nissan's response that range loss is occurring for Leaf's that have been driven a long distance, but Williams counters with evidence that contradicts Nissan's claims.

As TorqueNews noted earlier, a group of Phoenix-are Nissan Leaf owners staged a test last weekend to verify claims of battery pack capacity loss. This lost capacity would result in a shorter driving range than Nissan claims for the Leaf, and if true would make the Leaf a less-useful car.

The issue has been under discussion on the MyNissanLeaf forum for months, leading Nissan to issue a statement saying they were studying the issue.
