Definitely not a simple system, that is for sure. The division into separate modules not only allows more heat to be radiated, it alsomakes repairs cheaper, since this is clearly a "service by replacing parts" kind of vehicle. But the AC power inlet module being sealed to prevent repair is a problem, since cords run ito modules always fail at the module.So they have made the most likely to fail module non repareable. I really don't like that at all.
The aluminum modules will dissolve from all of the road salt used here in southeastern Michigan, and that will result in total module failure. That is what happens to aluminum anything in this area. So making the system last will need to come first if it is to be found reliable. And it would be interesting to see how one looks after a Deroit winter's road salt. That is one thing that you just don't see in California.
