First electric bill since charging begun.

That’s not a bad way to look at it. If you just consider the overall mpg as compared to the non- elec car, ln my case I calculated 104 mpg, the next time, 106 mpg. I think that is going to be pretty consistent in being representative of my future consumption. Of course that’s really MPGe, which equals the combined consumption of HV + ICE.. No other car gets this kind of efficiency. Congratulations on your purchase and enjoy.

 

How do you heat your home? Even Houston got some cold air, 20f's any way, over the last month. Any added electric use there makes your Prime look even better.

 

The Prime should only take a little over 6KWh to fully charge. If your $0.09/KWh is all you are paying, the cost of a charge should be more like $0.57 instead of $1.00...

Do you charge more than once a day? A $30 increase would be more like 50+ full charges at that electric rate.
Are there other per-KWh charges on your bill? Does your total electric bill divided by total KWh usage = $0.09/KWh?
Is it possible you used more energy for things other than charging the prius last month? If you die exactly one full charge each day, the prius should have only contributed to $17 of your bill.

 

Here in Austin TX, I’m seeing about 80 cents per full charge, or about 40% less than gas at 55MPG. Then again, gas taxes run around 38%, so it would be somewhere about even were it not for gas tax.

It’s a little higher in, say, July than in January, since the air-conditioning bill kicks us into the higher rate bracket (and since we have gas heating).

Everybody’s usage and costs will be a little different, not surprisingly. Plus of course, gas prices vary.

I charge, typically, twice per day: once to get to work and once to get back.

Or you used more electricity than the month before unrelated to the car.

We think a full charge from empty takes about 6.3 kWh from the meter

 

Speaking for myself at least, I only occasionally see much over 6KWh.

Can you use one of those kill-a-watt gizmos at the charge cord? Or is that old hat?

I think if you at least break even it's not bad, for various reasons. Would be nice to come out ahead though, seems that's the inference from the manufacturers.

 

How do you measure ?

 

Based upon what ChargePoint tells me after I unplug. I don’t measure it at home.

That makes sense, on an L2 charger.

L1 charging at home will have higher losses

 

Could well be...

My Juicebox Pro charger has me charging about 5.9 to 6.0 for a full charge.

My most common value is about 6.1...But I have seen some 6.3's show-up...I figure those are cases where I ended-up pulling a little more out of the battery during HV operation...+/- 5% seems well within reasonable bounds.

All L2 charging...

 

I have a Kill-a-Watt and ch caked the amount of electricity for a full charge. At my modest rates (about 0.10) it cost about 50-55 cents for a full charge. Where I am right now, regular is about $2.40 per gallon so it’s a significant savings.

 

Seems your calculation is very close to the eGallon calculation

 

I hope you fellow Texans are shopping for the best electricity rate available. I recently switched to a 7.7c/ kWh plan.

 

What part of Texas are you in, and which source/plan is that?

In a year or two, we’ll probably upgrade our house, and get solar panels. That’ll make the per-mile cost quasi-free.
