Prime electric bill cost to operate

well done! how much gas saved?

 

good info, thanks!

What do you pay per kwh?

 

My landlord charges me $15.00/mo. Since I'm in a 15 story apartment the electricity is commercial so my landlord pays .9 cents/KW.

 

I want to have your landlord

OP, if you are using one full charge once a day, that works out to about 200 kWh a month extra. At 11 cents a kWh the bill should have increased about $22 from the EV.

 

Actually, you want my landlord. He has agreed to let me install PV. I am going to pay about two cents a kWh over the lifetime of the array.

If I move he'll keep my labor invested in the installation and the electrician bill will be a sunk cost. I'll take my panels and inverter to the new place, or sell him the array at cost.

 

We often see two battery capacities: (1) maximum electrical capacity, and (2) operational capacity with the high and low buffers taken away.

• $69 / $.11 ~= 627 kWh # bill and kWh rate
• 627 kWh / 25 kWh / 100 mi ~= 2,500 mi # EPA 25 kWh / 100 mi
• 627 kWh / 8.8 kWh ~= 71 charge sessions (+2 per day?)

The number of charge sessions seems a little high ... not impossible. This is the problem of trying to use a variable, monthly bill as a meter for a specific load.

I'm going to suggest you might consider an electrical power meter (i.e., kill-a-watt or equivalent) for the outlet used to charge the car. This will provide a more accurate view of the electrical costs isolated from normal variations. If you do, get one that 'holds the metrics' versus one like the kill-a-watt that loses it in a power outage.

I am using an instrumented, Emotorwerks EVSE that records each charge session. They exist but cost hundreds of dollars. Still, I like to know.

GOOD LUCK!

The Prime's usable charge is about 6.3 kWh (at the wall) not 8.8, so ~100 charge sessions?
(EPA: 33.7/133*25=6.33 kWh @ the wall)

 

The cost increase seems rather high - you imply that you didn't charge more than once a day, and sometimes not every day? If that's the case I would think your costs for charging the Prime would be about a third of what your increase shows. Does your electric bill kWh USAGE vary widely from month to month for other reasons?

 

No problem as I bought my own Prime and drive it home Friday.

I'm guessing the OP is attributing the entire increase to the Prime which does not seem to match up.
I am guessing colder weather, more days in the billing month, or other factors explain most of the increase.

At 11 cents/kWh the Prime should only increase his bill $15-$20/month.

 

Yep. Or perhaps his entire bill was $69 ? Or he paid a lot more than 11 cents a kWh for the car charging.

Only thing for certain is that an error or mis-attribution is lurking somewhere.

 

Plugged fully charged...will consume from 0.4-0.7 amps......i will not go so deep how and why.....and this is measured by Fluke meter
