If the numbers I find online for tesla power usage is correct, that would indicate that she charges with around 1.8 kW. But most homes should have little problem supplying the double (16 ampere with 230v = 3.680kW). But maybe she is stuck with 10 ampere? But even with 9km/h I am surprised that's not enough, does she really drive more than 108km a day? (this is not to take away from her experience, I am just surprised)
