This might have been discussed in other posts before me but i am a little confused of how the different cables differ and actually work to make sure that you charge at a correct amperage and possibly voltage........? HPC to TESLA: a Controled signal between the charge point and the car, supplying known 70A. UMC also contoled but here it is the gizmo box on the cable that makes sure the right amps are signaled to the car? the spare connector there is no intelligence and the car defaults to 10-16A of charging? how does this all work if one imagines a Mennekes or a J1772 connector? does one need the little gizmo box from the UMC to control the amperes? or does the signal give enough info from the charging point to automattically tell the car what power is coming in so that there is no overcharging etc....?? these questions lead up to another one. if there is intelligence there, then could one not conceivably buy a couple of spare connector cables to get to the TESLA connector and then have RWE and some company doing official cables with J1772 connectors, or something like that, help us make new charging cables from this?? if one looks at the price of just a Mennekes plug they seem to run about $200 so yes first paying $600 for a spare connector and then another 200 and then probably another 500 or so for the pro job is more than just the parts but still about the same as a new UMC and that to me would still be worth it, if what I am thinking, cable intelligence wise, is correct. please help me understand if I am on the rifght track or completely of the base......? thanks for the help on this.
