Hi Guys,

so I started to look around for a charge/wallbox option at home, many models on the market, some suited for solar panels, some with or without badge , etc.
Yesterday a friend of mine, who used to own a tesla, told me he just had a 400V(380) plug connected to this 400V(380) circuit, without a wallbox or similar in between and had his tesla hook up to that directly. I even did not know this was possible. I am not a specialist in this field, who can tell me if this is a valid (low cost) option, or plain stupid because of ... ? Thanks

Isn’t there a simple protocol for requesting and acknowledging power from the charger? The millisecond that the link is broken with the car, the outlet is supposed to switch off. I would strongly advise to use a charging box, whether it is technically necessary or not. A charging box is essentially a switched power outlet with necessary safety functions.

I'm not sure that you "can" use this solution in Belgium. I mean you should have your installation certified after adding the outlet (or even a wallbox, but there is a specific "light" procedure for this) and I'm not sure that they will accept the usage of this outlet for a car. I know that it's not authorized in France for exemple. Obviously no one will come bother you if you decide to do it, but you could get some trouble with your insurance in case of any electric issue after the installation.

I'm wondering if it will come with a 14-50 or 6-50 connector for here in North America?
„The maximum power of 9.6kW is only attainable when equipped with the correct adapter (NEMA 14-50 or NEMA 6-50) on a 240V outlet.“

I requested the 400v 32a adapter to be delivered with my car, so I can directly connect the “flexible fast charger” to my in house wall connector. It should deliver 11kw of power.
A wall box is only needed (in my opinion) if the connector is publicly accessible, to prevent others to start charging on your costs.

Off course, a wall box looks nicer, and is easier to use since it manages your cables and you don’t have the separate charger black box laying around.

On a side note: the standard red 400v plugs are actually not rated to work at their maximum capacity for many hours at once, that’s why I chose the 32A connection, since the 16A would be closer to maximum. 400V 16A is about 11KW. 400V 32A will only be used for +\- 50%.

My wallbox is some wood I had kicking around, and some black paint. Hehe
