Mike's wife's monthly Kona EV efficiency report

I’ve always been an advocate of eliminating all “road” taxes on any energy type.

The “road” taxes should be covered by a simple formula, namely GVWR and kms driven per year. Have a matrix set up and regardless of vehicle type or propulsion type, that is what the yearly plate sticker fee would be…but wait, (temporarily) there are no plate sticker fees (in Ontario)

In that case, an argument can be made that “roads” should be funded via general revenue (income taxes). Even people who don’t own a vehicle enjoy a first world lifestyle via goods and services they use/consume that have arrived via use of the “road” network.

 

In both our EVs, the “loss” patterns are the same.

In cold weather months with little travel, the difference between what the car says was uploaded and what the inline meters say was pushed, increases.

In warm weather with lots of travel, that difference narrows.

For my wife’s Kona EV, the lifetime average is 20%.

Summary costs as of Apr 2022:



Total operating costs, per km (total costs minus capex costs):

$5.2517 - $4.8602 = $0.3915/km

 

Unfortunately, my brother created it years ago as it is way above my computer skills and he doesn’t want me sharing it.

Sorry.

Edit: however, I could explain the layout if that would help. Let me know if that would interest you and next time my laptop computer is on and I have some spare time I’ll post a short explanation. Cheers.

Discussion:

We are moving to an apartment on 28 July 2022, so the data for total kWh pushed from the grid (while at home charging) will become an estimate (as of 28 Jul 2022) until such time as I can figure out a data collection solution.

Cheers.

Summary costs as of 28 Jul 2022:



Total operating costs, per km (total costs minus capex costs):

$4.1759 - $3.8595 = $0.3164/km

Discussion:

We move today, so I have captured the July data early.

Going forward, the data for total kWh pushed from the grid (while at (new) home charging) will become an estimate until such time as I can figure out a data collection solution.

 

We were located near Trenton but have moved to Ottawa.

 

Aug 2022 results:







Summary costs as of 29 Aug 2022:



Total operating costs, per km (total costs minus capex costs):

$4.0897 - $3.7468 = $0.3429/km

Discussion:

Since we pay a flat rate of $15.00/month for whatever hydro is drawn from the grid to charge this vehicle (no inline meter available), the actual cost per kWh (and actual hydro drawn from the grid) is based on my best estimate of a 25% correction factor for this month (using historical data with a low use rate for the current month).

The insurance for 2022-2023 was purchased this month, thus the cost per km is somewhat inflated compared to last month.

 

It’s another 15/month.

We each have our own stalls.

My setup:

 

Yea, the “professional electrician” who did the installation would not have been my first pick. But, it’s not my private property so I live with it. Great idea ref the velcro strips; I keep my wall connector setup as is unless I’m leaving town for a trip…then the snips come out to cut the zip ties…and upon return home I have to monkey with it again for a few minutes to set it back up like this.
