Model S EU P71
One difference is that the Tesla 10 kW units are single-phase, wired in sets of 3 in 3-phase Y configuration, 277V phase to neutral, and I believe everyone else's modules are 3-phase. When I saw an Eaton 50 kW CHAdeMO being worked on several years ago, I could see the 3-phase structure (sets of 3 coils) in each 10 kW drawer. The Tesla design is more compact and simpler inside, and the production volume is high, keeping the price low.
Except that the module Tesla uses in Europa is 3 phase
Forcing Tesla to have 2 diffrent modules
The could just use the EU version is the US at is support both 1 phase and 3 phase charging
