What is maximum EV range of Prius prime!

25 miles is the official EV range, from the EPA tests. In reality, in favorable conditions (not a lot of hill climbing, moderate temperature), it is more like 35 miles. What you see from the Entune application (and on the display in the car) is a value derived from your recent driving.

 

it's really unlimited. no one knows the maximum range.

 

Mine displayed the best EV mileage for me this morning in the 6 months that I have owned the car. It read 39 miles. I feel a 40 coming. I love my Prime.

 

The EV range will constantly change and update, as it's just an ESTIMATE using your previous range numbers. If you only drive fast on the freeway when using EV you'll see it decrease over time. If you mostly only put the EV on for city or stop-and-go driving, you'll likely see it increase over time. Personally mine changes between 33-34 usually (mix of city and freeway) but I keep my speeds down.

Technically, you could probably cause it to show "10" by using EV only when going up big hills... or to show "90+" if you only turn EV on when going down steep grades/hills... but of course if you only use it under certain extreme conditions why even use it?

If you do a mix of driving and speeds, you should see somewhere between 23-35 (again, some people have numbers outside of that range, but that range is pretty normal).

 

My "estimated" was up to 38, so I decided to test it. I did everything in the most efficient way - pulse and glide - no air conditioning on - applied brakes thoughtfully - the "estimated" number totally matched my "actual" number until the last few miles, then it plummeted a bit. It went down to 34. Nothing changed in the way that I was driving. Very strange. I was totally hoping for 38, and really was bugged when it lost those miles.

 

As I understand it, "pulse and glide" is a technique that is only relevant in hybrids (or a plug-in hybrid being operated in HV mode). The idea is to "pulse" with the ICE on, operating it at a higher power output, so the ICE is operating more efficiently. And then glide with the ICE off in electric mode. In hybrid operation, all power ultimately comes from the ICE, and "pulse and glide" is a technique to make the ICE, when it runs, to run more efficiently. None of this relevant when in EV mode in a plug-in. "Pulsing" an electric motor doesn't accomplish anything since, if anything, they are somewhat less efficient at higher power output due to electric resistance losses. In EV mode, steady power is the most efficient.

 

I am currently maxed out at 42 miles on ev mode (and it's pretty close. More like 41 real miles as the with the last mile acceleration from rest drains the rest of the battery before I get up to speed)
I achieved this by trying to stick to the suggested acceleration (blue bar) - I forgot what the name for the tab is but it's one of the top screen selections .

I usually get 85-99% rating between acceleration, maintain speed, and braking stats.

If I plan on accelerating hard or going on the highway I select hybrid mode so the ICE carries that task.
Hard acceleration will drain the battery the fastest.
Of course it doesn't matter if you drive less than your estimated range, but my round trip to work is 58 miles so saving the battery for non-highway use is the most efficient

 

I just broke 40 on the guess-o-meter for the first time last week. I knew it was coming sooner or later . Still loving my Prime.

 

I am surprised by this! I appears as if the battery is charging when gliding, as the amount of miles I have "left" on the electric charge goes up. Can anyone explain this to me?

 

36.2 is the highest it has reported, but my actual range...I travel 15+- miles before the range starts to drop (downhill)

 

It’s a guess o meter, the more efficiently you use power the more miles you can go.

So it has little to do with how much energy is in your electric “tank” and more to do with how efficiently it thinks you can use what’s left

 

The estimate is based on your driving history and energy consumption rate. When you are "gliding" you are using almost no power so the computer guesses your range is increasing. When you are braking, of course, it can also rise because you are actually recapturing some charge into the battery with the braking.

 

In the pulse-and-glide procedure, the idea is to press the throttle a little bit when in "glide" mode, so the hybrid indicator shows neither charging nor discharging. If you just let off the throttle completely, a certain amount of regenerative braking is engaged, simulating the engine drag of an internal combustion engine (ICE). This adds charge to the battery, but slows you down.

 

pulse and glide doesn't work with ev driving. the only things you can control are speed and acceleration.

 

I was able to hit 27 miles (44kms), regular driving (non conservation), heater at 23C, up hills, down hills, city driving, 3/4 full gas tank, outside temp around 12C.

 

That chart seems a bit optimistic. It is based on the reported (aka estimated) mileage from the dash or actual?

The actual is rated at 25 miles bc the median of the chart appears to be at around 32. And I generally find the rates very accurate with maybe +/- 2-3 miles margin. I am unable to reach reported 32 miles in actual ev range
