Online Chart here: EV on board charging rates and times 

All calculations are based on 120V or 240V, times will vary slightly.

    The EV On board chargers : Sheet1 does not contain the same information I found in my owner's manual Pg 125 & pg 785. It says that the 2017 Toyota Prius Prime Advance can charge at 

    AC 240 Volt, @ 16 Amps approx 2 hours to charge and on AC 120 Volt, @12 Amps 5 hours & 10 mins.

    Why the difference on your datasheet?

    HI Alan,

    The data I found (and it may be wrong) is that the onboard charger for the Prius Prime is a 3.3kW rate.

    The charging rate for that using Ohm's Law (P = IxE) is 3300/240=13.75 amps.

    The battery I have found is 8.8kWhrs, so 8800/3300 is 2.66, or about 2:40 to 3:00 hours to charge on 240V.

    The 120V time I have is also based on the same info, 8800/1400 is 6.28, or about 6:15 hours to charge.

    If you have a larger onboard charger, maybe a 3.6kW, then the numbers you have would make more sense for the 240V times.  Let me know and I will correct it.

    Thanks!

    "Prius Prime’s battery can be charged in less than 5 hours and 30 minutes by plugging the included charging cable into a standard household outlet. When using a public charging station (240V), Prius Prime can be fully charged in approximately 2 hours and 10 minutes."

    Clarence, do you have a Toyota Prius Prime?  I would love to know if the onboard charger is 3.3kW or 3.6kW.  Of course, that would only change the 240V time slightly.

    No, I don't.

    Here's what's on the back of my Prius Prime charger.

    Alan,

    A 120V 12A EVSE charges at a max rate of 1.4kWhrs.  With an 8.8kWhr battery pack, it would charge at 6 hours 15 minutes.  If however, the useable battery pack is only 7kWhrs, then 5 hours would make sense.
