what about the Ford Focus EV? it has 3 separate cooling loops that can be used in any combination to maintain temps of battery, inverter and charge controller.I won't say that I think the temperature range is good for the battery, but it is acceptable to me rather than having a complex, power-consuming thermal management system. Liquid cooling without a refrigeration system would be of little benefit with the high ambient temperatures common during the daytime in Phoenix. If a refrigeration system were used, the battery capacity would need to be much larger to give the same range while running the compressor and moving the heavier vehicle down the road. I prefer the simple air-cooled solution Nissan has chosen.
it has a 23 Kwh pack but is reputed to go farther on a full charge than the Leaf. so maybe there is something to the management options for people in very warm climates.
as for me? i go with the cheaper Leaf since i dont have those high temps to worry about. the highest ive seen is 6 bars and i am guessing in the heat of Summer after a QC i might see up to 7 or 8
