>Is my dedicated meter and 50 amp 240volt service, which I installed when I was doing my 1st full conversion in 1999, level 2 or 1?<
Since Mike is in the U.S. I would call his nema 14-50 outlet (my assumption) level-2. That's because before there was j1772, there was Avcon and LPI/SPI hardwired to a 240VAC 40A source. Before that there were nema outlets (and no one had 'levels' defined yet). IMO, an electrical power source is an EVSE: a nema outlet, Avcon, LPI/SPI, j1772, L3 CHAdeMO/ccs/tesla-3phase/Euro & Asian types, etc. In the U.S. where a home, or business would have a 120VAC 20A outlet as common, that is considered level-1. Voltages in the 200's is level-2. Above that is level-3. I have a news wire I will post later that puts the power above level-3, yet I have not heard of a 'level-4' being defined (or even talked about). But with CARB credits pushing for instant-gratification (wasteful, ultrafast) charging, and now 200+mi range pack becoming the new norm, perhaps someone will (SAE?). To try to get technical about this can muddy the waters (confusing sources): https://en.wikipedia.org/wiki/SAE_J1772#Charging (Their L1 defines a 16A draw when actually production plugins max at 12A. And their level-2 does not show all the level-2 power levels actually available) Other sources have their own definitions/opinions: http://large.stanford.edu/courses/2014/ph240/lin1/ ... Level 1 charging method uses a standard single phase alternating current (AC) of 120V at up to 20 amp ... Level 2 delivers up to 20 kW of power from either single or three Phase AC of 208-240V at up to 80 amps ... http://www.nissanusa.com/electric-cars/leaf/owner-questions/ev-charging-routine (Nissan calls level-1 a trickle charge and level-2 and overnight charge ...) http://www.pluginamerica.org/drivers-seat/understanding-electric-vehicle-charging (dated but applicable) ... Level 1 charging is the technical jargon for plugging your car into an ordinary household outlet ... Level 2 supplies 240V ... allows for a wide range of charging speeds ... http://www.afdc.energy.gov/fuels/electricity_infrastructure.html ... AC Level 1 is typically used for charging when there is only a 120V outlet available ... Level 2 offers charging through 240V ... Yup, it can get confusing. For my money, lets make it simple, in the U.S.: 100+VAC is level-1 200+VAC is level-2 (20kW max) any AC or DC voltage above that, I consider as level-3.
