A very good question. As you say, you’d expect the losses with the GC to be a higher %. If the battery is starting from cold in cold weather and has to be warmed to c30degC, that’s a lot of energy and I’d expect the efficiency to be very low at the start of the charge.TeslaDriver wrote: ↑Wed Apr 17, 2019 7:47 amIs there an issue of Efficiency charging at 13AMPs vs. dedicated 7kW wall charger?
unlike iPace Tesla has some parasitic usage
Perhaps also an issue if preconditioning the car whilst battery charging? I don't know how much of 13AMP that would be, but as a percentage it would be less on 7kW Natch!
Has anyone monitored this? I haven’t even tried my GC yet.
And I don’t know where you get the idea that “unlike iPace Tesla has some parasitic usage”. I-Pace certainly will have charging losses. I think you are referring to the fact that I-Pace has a very low “vampire drain” - loss of %SoC with time when not used.
And BTW, it may have a 13A plug on it, but it is limited to 10A...
