Nissan is one of the only plugin automakers with no Thermal management. This has caused thousands of battery pack in the Southern USA to lose too much capacity to be usable by most people. Even in cooler areas the batteries lose capacity much faster than any other electric vehicles. In fact a few hybrid companies learned that they at least needed to add fans to blow air over the packs for much longer life. (The Prius added fans in the 2004 model and got 10x longer battery life). Why hasn't Nissan learned this ? A group of LEAF owners (including me) meet with Andy Palmer when he was a head of the LEAF program at Nissan. Many owners explained that they loved their LEAF but the batteries were losing 10-20% of their capacity each Summer. He said they will never have cooling. He used to work in Air Conditioning and it would be too prone to leaks and failure. Until this has been corrected I will never own or lease another Nissan.
