Cost to Recharge the Prius Plug-in

Kill A Watt does have KWH setting. and total hours charged

 

This thread was from before anyone had gotten their PiP

 

yeah....I noticed that

 

Here is another way I came up with to compare costs between Gas and Electric:

Comparison between gasoline and electric usage for 100 miles. | PriusChat

 

I did a spreadsheet for Southern California Edison.

I've decided against the TOU-D-TEV plan (Time of Use Domestic Tiered EV Plan).
The reason -- with a drivable distance of only 13.5-15 miles per charge, I would like to charge more often.
I may want to come home, charge the battery, then take off again.

Here is my breakdown:

TIER ----- COST ----- CHARGE ----- MILES ----- CPM ----- CP50M
1 ---------- 0.13 ------- 3.0 ------------- 13.5 --------- 0.03 ----- 1.44
2 ---------- 0.16 ------- 3.0 ------------- 13.5 --------- 0.04 ----- 1.78
3 ---------- 0.25 ------- 3.0 ------------- 13.5 --------- 0.06 ----- 2.78
4 ---------- 0.28 ------- 3.0 ------------- 13.5 --------- 0.06 ----- 3.11
5 ---------- 0.13 ------- 3.0 ------------- 13.5 --------- 0.07 ----- 3.56
Gas ------- 3.94 ------- N/A ------------ 50.0 -------- 0.08 ----- 3.94


So at all times, if I did the calculations right, I am still saving over gas prices per 50 miles -- although tier 5 which I did hit in August came very close.

 

0.10 gbp per kwh in the UK would cost me 34p give or take cost. Due to hills I get no more than nine miles for that 30p.
I was costing me 25p per mile. Much cheaper using the prius.

 

25 euro cents per kwh over here.
Even with the high petrol cost, its just a little cheaper then running gas.

Little late to the party, but with the current set up of my TED (The Energy Detective), I'm seeing about 2.9-3.3KWH consumed on a full charge. I'm relying on the software to determine that, which identifies a load based on recorded charateristics. Admitedly, there are a couple of other loads in the house that will at least temporarily mimick the load from the Prius and the software lumps that consumption into the PiP bucket. I have a second unit that I plant to dedicate to the garage outlet used to charge, which will help clear the waters.

 

You would have to do a monthly average in order to assess an approximate price by season. Are you returning to recharge almost empty or full empty?; it does make a difference.

 

From an all EV perspective, completely empty. I do suspect, though, that the state of charge of the battery (say 4 bars vs. 6 bars etc...) when the car returns to the garage in HV mode will drive an additional .1 or .2 KWH depending.

As it is now, I'm having to average the per cost price and KWH used and I'm not overly confident of the accuracy achieved. Need to get motivated to tear back into the breaker box and get the second and third transmitting unit up and running. Then, I'll know that any readings are driven solely by the Leaf or the PiP.

Do you have a TED or similar system operating with your PV array?

Edit: I should clarify that the 2.9-3.3 from above is not an actual reading, but a "solved for" result, after accounting for the assumed 75% efficiency of charging. The actual readings are 3.87-4.4. Sorry for any confusion.

 

My PV was recently assigned the PTO (permit to operate) and was commissioned a few months back for assurance of operation by my Solar Contractor.
I own a TED 1000 since the last 6 years, I was one of the test bed for the company at those days, and it worked flawlessly since and provide me the right information.
I purchased a TED 5000 for a total of 3 independent readings recently and was waiting for my electric provider (LIPA) to complete their job with the PTO in order to put my hands in the house load center and interface the clamp on probes at the PV feed line next to the NET meter.
So, in short, I will have all the capabilities of measuring and evaluate my Watts loads as necessary.
