No, not what you're thinking. We have a bunch of Blink charging stations at my work campus, and one of my co-workers has been having trouble with charging his Honda Fit with them. I mentioned that I'd seen some voltage drops reported on the Tesla. So we spent the evening running around all the chargers and measuring the voltage and current at full (30A 208V theoretically possible) delivery. Well, most of them delivered 30A, but also mostly at around 199-201V. Note that even on multiple chargers in the same structure, the BGC was the only car actually charging at the time. However one of the chargers only delivered 191V, and often the car only showed 29A. We suspect that there's some bad wiring in or near the charger, since it seems to be throwing away about 450W. That's a small space heater! So, anyway, it turns out that Tesla makes a very nice portable meter, for testing J1772 systems! None of the other EVs we knew about had any similar capability. A bit expensive for the functionality, though.
