Weightlifters charger 11kW (Tesla Gen2 based CHAdeMO charger)

Behold, another mayhem from the charger front.
Got a good price on a Gen2 Tesla charger and as I'm now maintaining the software I thought it would be good to have one.
Then I went to the scrap yard and got a water pump and a, irony of fate, Polo passenger heater assembly. Yes the one the killed my Polo. Tubed that up with the vertical tube being the reservoir and from then on called it the weightlifters charger. It is painfully heavy.
Then attached an Anderson connector to the DC output and a Wieland RST20I5 to the AC input. The Wieland is a great part, 3 phase and with 20A capability per phase at a fraction of the size of a regular CEE connector. I made two counterparts, one with Schuko plug and one with Type-2 plug (powered by Arber).
Added a Meanwell 20A supply left over from the Polo.
Since this is a CHAdeMO charger I make provision for that. Straight connection to the Meanwell on pins 1 and 2, CAN and charger enable 2 signal are on the connector anyway. Just jumped it over to the 12-pole connector which has vacant pins. Internally pulled up the enable pin and will add polarity selection to the software so it charges when the signal goes LOW.
So much for now, first test tomorrow.
