Most public J1772 stations provide 30a @ 208 volts for 6.2 kW. Sometimes they will be a full 6.6kW, a few will be limited to 16a or 24a. A very few will be higher amperages like 40a or 70a. There may be a few that share power like you suggest, but most stations with two plugs supply the full power to both. Plugshare.com is the place (and app) that's best for both finding public charging as getting these kinds of details about a site. You also get user feedback about reliability.RustyShackleford wrote:Thanks for being gentle, guys. One's initial impression is that all public charging stations are capable of quick charging. No. And it sounds like one of these public L2 stations may not even provide the full 6.6kw rate, especially if two cars are connected.

Now the amperage/voltage limitation is at the charging station primarily vs. the car in the other scenario.
Most all homes are wired for two phase (~ 220V for some applications), and that provides the ability to develop the higher L2 charging power.SalisburySam wrote:Lastly the L2/L1 charging stations are all single phase, likely how your home is wired.
Er, no. Two phase hasn't been in use for any but very specialized applications in many decades. Home current is usually a transformer at a telephone pole or on the ground that reduces transmission voltages of 12kv-14kv to two 120v lines and a neutral that connect to your home's meter.lorenfb wrote:SalisburySam wrote:Most all homes are wired for two phase (~ 220V for some applications), and that provides the ability to develop the higher L2 charging power.SalisburySam wrote:Lastly the L2/L1 charging stations are all single phase, likely how your home is wired.
