Prius Prime XSE/XSE Premium dismal BEV range

No way 73 miles in EV. Sorry but not possible.

 

I have a RAV4 Prime and I also use EV Mode on the interstate, but only for a very short distance (6 miles or so)

 

Both days involve about a total change in elevation of about 500 feet one way so not flat. Up in the hills down to sea level and back.

For the fist set of calculations I used the Toyota iPhone app to charge details to get a value for how much energy I used to recharge after I drove the 31 miles. I got the distance driven from Drive Pulse & Trips.

For the second set of calculations I used again the charge details and since Drive Pulse & Trips had not updated with today's trips I used google maps to measure the distance back and forth.

I am charging with the OEM Toyota charger on a 250V 30A circuit.

 

Charge adapter works really well on 240 V circuit. Haven't noticed any excessive heat from the charger and have been using it with an adapter for about 4 days now.

Used Rob43's thread Using the Primes 120v Charger at 240 Volts, Cost $20 !!! to make adapter.

I will have to look into getting a watt-hour meter. Thanks for the recommendation.

 

not to pick nits ... but me thinks you are talking about the evse? because the charger is built into the car.

After 400-ish miles of around-city driving without using any gas, finally took my first 100-ish mile trip today. I topped off the battery and while I didn't measure precisely (wish I had), I got just under 40 miles on my XSE Premium before the battery died. That was 95% interstate driving AND that included about 2,000 feet of altitude gain.

I did notice for one of my city trips where I decided to have fun and drive crazy (well, crazy for a Prius driver), that I certainly drained the battery a LOT more than a nearly identical errand driving like a normal Prius driver. I'm sure that if you try and drive the car like a sports car it would be pretty easy to cut efficiency in half whether it be gas or electric (or both!). The famous "Top Gear" guys did exactly that.

Purchased ZHURUI PR10-E US15A Power Meter Plug. Higher max power rating for 240V. I'll recalculate my numbers once I get it and post my results.

 

Miles/ kwh makes more sense to me, like miles/ gal. Rather than range comparisons. 4.7 is pretty good consistently.

 

I reset my m/kwh in mid-July after our vacation and driving locally, I'm getting 4.9 over roughly 2 months.

 

I updated my calculations with the overnight updated numbers for Charge Details and Drive Pulse & Trips. With the new numbers for distance being 11 miles and the charge amount 1.751 kWh both from Toyota app I get 6.3 miles per kWh and total range of about 65 miles.

Drove in Eco Mode and used regenerative breaking at maximum setting going down hills and when not using cruise control. Also car was comfortable both times I got in so I didn't use much if any A/C.

Later in the week I will see if I can duplicate these results once I get the watt-hour meter.

 

I'm on a short trip in the Rockies at about 8500 feet. Not great milage coming up, but looking forward to the drive back in a few days. On the way back I climb up to 9500 feet which I should be able to do all-EV, then looking forward to seeing how much I'll get put back in on the decent down to ~6500 feet. In my Gen1, I'd completely fill the battery before getting to the bottom of the hill and it would start engine breaking. I figure I'll roughly deplete about half of my battery getting to the high spot then see how much I get back.

That is some impressive driving. My highest ever is 4.8, but average is only 4.3.

 

Are you driving up and down the mountain in ECO, NORMAL, SPORT or some CUSTOM mode?

 

Here is a video of their range test

That’s the same as my Volt when it was in good shape, makes me more disappointed Chevy didn’t keep making it and Toyotas “Volt” costs a lot more

 

When the EV range ran out did your Volt get anywhere close to the new primes 47 highway, 50 city and 48 combined mpg’s on solely HV mode? How much EV only range did the Volt get?

 

Be forewarned I am a hypermiler…

Before the pandemic drastically changed my life and driving habits …
About 9 months a year my volt did this on my twice weekly long trip.



I’ll let you do the math since the car breaks it down.

Consistent EV Range 68-72 miles
Gas economy varied by temperature and how much of a hurry I was in 40-50mpg was common. (The volt lets you engage and kill the ice pig at will so you can game its positive behaviors on the highway and preemptively “coast” if you know the engine should be off coming up)

My “lifetime “ economy has always been low because of the immense number of gas miles I would do (and lack of charging infrastructure).
back in the day I took the car out west nearly every year 3000-4000 miles of siteseeing, Volt camping and national parks. I actively tried to choose places with charging but even quite recently it’s just not there , usually only got 3-4 charges on a long trip.

Sadly I no longer have a cream puff drive, the car has gotten beat up, I don’t have LRR tires and the infamous battery longevity update has sort of ruined my ride.

My unfavorable ratio of gas to EV miles is why I got the Volt and at 3500 EV miles a year is also why I oppose PHEV registration up charges as they are written.
I’m either going short distances in the city (all EV) or long remote highway miles (minimal EV possible even with a dedicated bev).
Of coarse post pandemic my multi vehicle family no longer drives very far at all.

Ah well
