    $0.15 per kWh is a good deal, away from home. Heck, there are many who pay more than that at home. With overnight (off-peak) discounts, you'd probably pay less. I pay $0.08 per kWh.

    By the way, it's interesting to see a power provider with such a profound typo in their bill. A reference to "kW" means speed, not quanity. So, the "Energy Received" is incorrecct. It should be "kWh".

    I tried charging it during the middle of the day and from 9pm - 1 am and the price seemed to be the same, $0.15. So I dont think there is any "off-peak" discount.

    Also, wouldn't the kW be referencing an amount, and kWh be the time measurement?

    that's incredible. that charge at my house would be over five dollars!

    but my brother lives in naples, and it wasn't too long ago that he was paying .06 cents/kwh.

    he was really whining when it went up, until he saw my bill.

    KW refers to the power, kWh is an expression of the power (kW) for 1 hour (kWh).

    A good analogy I have heard is to consider kW as the rate of water flowing into a bucket. Then kWh would represent the amount of water that is in the bucket at the end of 1 hour.

    The terms are confused with each other quite often.

    kWh = quantity

    kW = charge-speed

    OK then what measurement would you use to represent the total amount of power delivered after a certain amount of time? I suppose that is what it should say on the receipt.

    My utility bills me by the KWh; but my peak rate is 0.3279 kWh. That's approaching the price of just burning gas.

    Confused on how you can put 11.65 KWh in a Prius Prime though. Isn't the battery just 8.8 KWh? That's a lot of overhead.

    Ouch, here, it's $0.069/KWh for the first 40 MWh then $0.097 for the remaining KWh of the billing period (60 days).

    O'Canada; and their hydro......:D:p

    re: 11kWh charge; Charging losses and I'm sure the meter is skewed in favor of the vendor - but still a very good price for a public charger. Around here; I've seen machines as high as 0.90 kWh plus an hourly charge approaching $1 an hour - to discourage people from hoard the charger. Some has a $3 flat rate fee, just to hook-up, then start charging 10x peak rates.

    Yeah, at work I have a three hours free charge then it's $3 per hour (240V/30A max). Also includes free parking while charging, otherwise it's $17 per day! With the Tesla, I can adjust the charging amperage from 5A up to 32A in one amp increments directly from my phone so I can adjust it to use the full three hours (lots of free chargers so I'm not preventing someone from charging). I haven't tried with the Prius yet (tomorrow being the first time). I can adjust, in car, only between 8A and 16A. My ride is 26 km and half highway so I'll probably use most of the battery, let's say 6KWh. At 240V/8A, it will probably be topped or close to topped by that three hours free charge limit. I only work at work half a day a week so it turns out fine.

    Doesn't answer OP question but something I put together to help me decide gas vs charging.

    I missed the response . Did someone answer #9's question re: 11.65 kWh v 8.8 kWh. If it is actually around 11.65 kWh capacity, is part of it a reserve that cannot be used for driving. By that I mean when my percentage reads ---% and I recharge it, the app shows 30% > 100% not 0% > 100%.

    Thanks sylvaing. Do you know if part of that 11.65 kWh in the battery is reserved for other car needs and so not available to extend the miles on a charge. I read somewhere that about 30% of the kWh battery capacity is reserved so that when you fully charge from a ---% the app will show about ~ 30% > 100% and not 0% > 100%.

    Anyone know if this is basicall true?

    If you use the app Hybrid Assistant, it will show that for a battery shown as 100% in the car, the real State of Charge (SoC) of the battery is around 85% and 0% is actually 15%. What's above 85% is not used to preserve the battery's life and below 15% is used by the Hybrid system, although it tries to stay around 15%, again, to preserve the battery's life.

    Hybrid Assistant is an Android only app that gets the raw data from the car through an OBD2 adapter and display that data in a readable format. Any Android devices released after 2012 with at least V4 will run Hybrid Assistant.
