GlennD said:The Tesla charger is weasel worded to be 10K. That is 250V and 40A. My 240V is certainly not 250VAC. I do have a KW meter on my charger and at 245V I have seen over 9.6KW from the wall.
rdavis0521 said:I couldn't say for sure, but that's faster than the car can charge (10.93kw). What I'm guessing is that is wall power, and not what is actually taken in by the car battery.
I believe the efficiency factor, as per Tony is about 83.3% (charging is not 100% efficient). With that I would easily believe that your car is charging at about 9.1kw?
rdavis0521 said:So now I am confused. Are you saying that effectively the car can only charge at a max of 8.2 a 8.5 kW? There is no way to get 10kw to the battery, regardless of EVSE capacity?
evnewbie said:I have JuiceBox Pro and I have analyzed the charging session stats it reports and they are typically 5% lower than what's reported by my utility company for the charging session. So, JuiceBox does not provide accurate actual wall or battery power stats. I am guessing the stats represent power delivered from the JuiceBox to the onboard charger.
