Kill A Watt Meter readings 2012 to 2014

Cutting it sorta "close" yes?

 

Another factor which has to be taken into account when trying to determine how many kwh one gets in a charge is the state of charge when you start charging. I was playing around getting the charge as low as possible in HV mode (3 bars, I think) before starting charging, and it made something like 200wh difference.

 

I agree with CharlesH.. also, temperature will make a difference. Cold temps will decrease capacity a bit.

 

I think temperature makes a much bigger difference than we realize. There is now at least two years of data from the early adopters. But the one piece of data that hasn't been as well collected so far is that of ambient temp and EV range. I think we know observationally that wintery, cold-weather temps are tough on EV range. And other casual observations tell us that very hot conditions are also rough on EV range.

But so far, I haven't really seen much data to really be able to say just how much ambient temps affect EV range. My conjecture is that there's a sweet spot of temperature range (and perhaps RH as well), and that outside of that range, the EV range declines. I also suspect that towards the extremes, there is even more of a decline. But so far, we just don't have much data to help with these conjectures.

 

Problem is that it's rather difficult to have WINTER mornings followed by SPRING midday, with SUMMER sunsets (wink,wink).

 

True dat…

 

Actually @giora pretty much did that in his post here: Actual EV Range and Temp Relations | PriusChat. Unfortunately, temperature range is quite narrow in his climate.
