I have an agreement with my landlord to charge my Prius Prime 2017 overnight. I live in south jersey (PSEG). Landlord is asking for reasonable reimbursement. Landlord is using Solar panel as well (which I am not taking into account) Does my below calculation looks reasonable: As per: https://www.electricitylocal.com/states/new-jersey The average residential electricity rate in New Jersey is 15.78¢/kWh, which ranks 7th in the nation and is 32.83% greater than the national average rate of 11.88¢/kWh. Prius Prime: 5.88KW for Full Charge Complete charge when needed in full = 5.88x15.78 ~= 93 cents per day The car is usually half charged, so 50% of charge ~=38 cents Off-peak electricity is 25% cheaper ~= 38 - (38 x 25/100) ~= 29 cents per day 10% of days charging spot not available ~= 29 - (29 x 10/100) ~= 26 cents per day 25% of days for fast charging free used free EV charging ~= 26 - (26 x 25/100) ~= 20 cents per day 20 cents for 30 days ~= 20x30 = $6 per month Does the above calculation looks reasonable. Any suggestions?
The calculations look reasonable, but it's 6.8KWh on an empty traction battery - with the whole traction battery being about 8.8KWh. It really doesn't matter what we think; Will your landlord go for your calculations. It'll probably be easier for you to settle on a price and buy one of those kilowatt energy meters. You both go out and reset it every first or fifteenth of the month. It keeps everyone honest, and they don't think they're getting taken advantage of. You can also do some research on state-, county-, and/or city- wide incentives to install charging stations for your complex. They can ekk out a small profit and give you a discount for doing all the leg work. FWIW: My monthly electricity cost for my Prime is $18.25 @ $0.1082KWh. I plug-in daily and empty my pack daily; so I personally think your numbers are low. What is preventing you from charging during peak, more often, and using more electricity - once a monthly price is settled upon. I'm not saying you made these mistakes on purpose; I'm just saying your landlord is getting the "short end of the stick." IMHO: there needs to be a win, win in these negotiations; otherwise the answer is a short simple NO. That's just my 2-cents
Agree with bisco. I would give him a dollar for every time I charged. Show him your calculations so he knows that sometimes you use about a dollars worth of power, and sometimes you use less, but in the end you are paying him more than the actual cost. If you charge every day, just add $30. to your monthly rent and the problem goes away.
Why not use the actual utility rate for this property? Some locations and customers are stuck with higher than average rates. Arithmetic error? 50% of 93 cents comes out to 46.5 cents by most people's math. And this is separate from the too-low full charge energy at the wall outlet side of the EVSE.
Make sure to buy and use this. There is no fair way of determining the electricity usage otherwise. It will show the cumulative kWh usage, even if unplugged. I use it in my garage, and it works very well.
Here in NE Illinois the electrical utility offers an hourly rate that often is actually negative in the middle of the night and very often extremely cheap. Was it the Landlord’s idea to charge it overnight night?
Thanks for the input. I can only charge at 8 amps, so it takes about 4 to 6 hrs, when low on charge or 7.5 hrs on full empty. Overnight charging works best for charging the car for 3 to 6 hrs on average. When I need fast charging, then I use free fast charging in 2hrs, which is available here outside few grocery stores. As per Biomed01 "My monthly electricity cost for my Prime is $18.25 @ $0.1082KWh". This looks like a very reasonable rate. $6 or whatever I put forward, will not be per expectation from landlord. I will reach some middle ground with landlord between $10 and $15 per month.
