The Truth About Prius Prime EV Charging

- Today I talk about the Toyota app and how inaccurate it is in reporting the power consumption from each charging session. I purchased a WiFi charging meter to record the power consumption from each daily charging session and I compared it to what was reported by the Toyota app. The results and comparison are quite interesting and definitely something you should know about before making a purchase decision based on the projected cost savings of owning the 2023 Prius Prime.
Please see my earlier video where I discuss overall range between gas fill ups: • How Far Can a 2023 Pri... - Auta a dopravní prostředky
The meter tool counts the amount taken from the electric network, but part of this is lost during the charging process. Longer the charging time, more the loss is (but seems a bit much in this case).
Most likely the Toyota App counts only the amount taken into the battery without the losses.
Meter plugin is pretty accurate and I’ve charged publicly as well. In both instances the Toyota app reports 55% of the actual usage of actual draw. My electric bill corroborates the meter draw as well. It costs about $85 to charge monthly and I fill up every five to six weeks with about 8-9 gallons of gas. I would spend $125-150 with my 2015 Prius for gas doing the same commute, so somewhat cheaper and really more convenient to charge at home overnight. The real advantage is using the HOV lane for commuting.
Comparing my last ChargePoint of 6.723 kWh to the Toyota report of 3.605 it is only 54% of the ChargePoint measure. I hope this is fixed one day in an update.
The ChargePoint Measure is reasonable considering the battery was more than half drained. Also 2hr 20 minutes is reasonable for a half charge time. The Toyota number is just wrong.
At home I am completely off grid and that is where the car normally charges so the electricity has a marginal cost of zero. I think for an off grid user who has enough electricity for a Prius Prime but not for a Tesla it is the best car in the world at any price.
If I’m remembering correctly…
…the meter’s results are very consistent with the results of the public charging app you use when you charge for free. (At the beach?) That app gave you results that were (exactly?) the same percentage off from the Toyota app. (I think.)
💡 Idea:
*If you feel like it, why not bring the meter with you the next time you charge for free at a public charging station?* And see (I think) that the public charging station app is giving you 100% accurate results.
And if you wanted to use the meter’s app, then maybe you could switch your phone’s “mobile hotspot” On. (To provide the WiFi for the app to function.)

And thanks for making this video about the meter! 🙏 🙂

Good point:
The public charging station doesn’t plug into a wall outlet! 🤦♂️
Oopsie! My mistake. 😄
I'm paying ~2.40 for a charge here in Florida. With gas prices where they are (3.43), I worked out its about $0.02 more per mile. I'm not sure thats even worth charging. Maybe you can check my math.
I think the value for me is using the HOV lane and not having to visit tie gas station two times every week. If I wasn’t commuting so much it really wouldn’t be worth it
