Is it still possible to buy a UMC or an adapter for the one included with the car that will charge in a 3-phase industrial red plug? I charge in some places where a 32A circuit is not feasible. But those places do have 3-phase power and it would be nice to be able to charge a Model 3 at full power if needed (3x16Ax230V=11kW). I know the HPWC can do it, and in the US there is the NEMA 14-50 UMC. Is there an equivalent model for three phase power? I've seen in a couple of threads that this is something @arg might now. So hopefully it's not too much abuse to ask by name. Thanks in advance.
Well, if you could find a V1 UMC then it would do what you want; however, the V2 UMC is apparently single-phase only. It appears that Tesla are now supplying the V2 UMC with all new cars (both Model S/X and Model 3), so the V1 is probably out of production. Possibly you might find one in old stock at a service centre. They also appear regularly on eBay. But what you need isn't Tesla-specific, there are third-party alternatives that do the same job, such as: https://www.juice-technology.com/juice-booster?lang=en EVR3 - Type 2 - max 22 kW [Portable charging station] - e-Station Store
I hadn't found these. They looks perfect, thanks. Being able to adjust the maximum current in the charger is great. It allows not depending on limiting in the car to work with lower power circuits. They do look a bit pricey, maybe in part because of the 22kW support, but it at least gives me confidence I can definitely go this route in the future if I need it. I'll prepare the installation for 3x16A and see if I get along with 3kW for now and buy a 3-phase charger if not.
I use the juice-booster often when underway. It can serve also as the home wall-box. You can connect try-phasic to the red 3x32 as well as the red 3-16 sockets. The car will then always charge at 11kW as that is what the cars rectifier supports. Also the connector to the blue 16A or the respective domestic sockets get some use. It expands your "destination charging" versatility considerably. For cross-border travel you can get sets of connectors for various European countries.
Am reasonably certain the UMC that came with our 2018 MX has support for 3 phase charging because I used it to hook up to a red plug at a hotel and got at least 11kw if not 16kw. I’m also pretty sure that it’s a v2 UMC.
I bought the Juice Booster 2 instead of the UMC v1. Very high quality kit and tons of adaptors available.
It's a Gen1, Gen2 is single phase. Yep, that seems to be the best option right now. It's a 1000€ extra cost though versus just getting it standard with the car like you used to before.
Yeah that’s true, but I guess I’m used to the adaptors game as I had a 2012 Roadster for 7 years. I compared the cost of buying the v1 MCU and it was 700 Chf so spending the extra 300 (1000 or so) for the Juice with the quality and abundance of available adaptors made more sense to me. I actually bought the Juice Booster Europe Travel kit which was 1,600 Chf. ;-)
I can see this is an old thread, but you have the numbers wrong Pedrocr... 3-phase red connector is 400V and the blue is 230V. At 16A you can get maximum ≈6,4 kW on 230V 3-phase, but 11 kW on 400V. I just received my ‘21 Model 3LR this monday, and my UMC only had the Schuko plug included. Is it possible to change the connecting cable to a 1-phase blue CEE, so I can charge 16A instead of max 13A? I will of course buy a home charger for better capacity, but as a temporary solution, I would prefer to maximize my available option.
