Todd and Kari with Mini E #140 just posted a link to a You Tube video with Josh from AC Propulsion. If you look at 4 minutes and 50 seconds, you can clearly see that AC Propulsion has connected a 30 amp, 120 volt "Travel Trailer" plug directly to the charging cord for the Mini E. This allows them to charge at 3600 watts at a Recreational Vehicle park in the US. This is more than twice as fast as the usual 110 volt 12 amp yellow charging EVSE (Electric Vehicle Service Equipment) that Mini supplies in the US. But I find it a bit odd that they are showing this, because the electrical code requires that drawing current at 100% of a connector capacity (30 amps in this case) should be limited to 3 hours, which is not long enough to fully charge the Mini E. The code says to limit current to 80% of rated capacity when the load duration exceeds 3 hours. But then again, AC Propulsion can probably set the current draw to 24 amps in their car, which the rest of us cannot do. We have to live with 12, 32 and 50 amp settings. (All of which actually draw slightly less than what the setting shows.)
Then I see that MINI-E Driver Stefan Reitmeier from Germany posted a picture of his car plugged into a wall outlet without an EVSE. Maybe the regulations are more rational in Germany than in the US?
In any case, AC Propulsion has state of the art safety features built into the charging system in the car. But only an external EVSE can provide the "dead front" connector to the car. In other words, the connector face stays unpowered until it is actually engaged in the car receptacle. So although I admit I have charged without an EVSE myself, we should all avoid it whenever possible and stick to the US rules and Mini guidelines.
It is interesting though. Someday the US rules may change and charging will be more flexible.
