EV Miles estimate after Full Charge LOW

What you describe is normal. It's all estimates. There doesn't seem to be a precise connection between the actual range and the estimated range. You are probably not running out of range before recharging. Here are some of my observations: whenever I have days where I have not used all of the range before charging, the estimated range is always less the next day. Conversely, whenever I'm able to get a long run off of a charge, the estimate is always greater the next day.

There are other threads on the PHEV forum regarding your observations.

 

Picked mine up on April 27. After first charge, showed 13.1. Now after two months shows 14.7 to 15.2. I'm still on my 2nd tank of gas with 2650 total miles since I picked it up. Current tank of gas with 5 bars, 1067 driven so far. Looks like either you have a lead foot or something is wrong.

 

bfd has it right. the important thing is, how far can you drive on ev?

Bayarea99 is the exception. Most people see the estimated EV range decline.

It is not based just on the battery charge. That is only part of the equation. The other part is how far you can go on each KWH of power. One example of this is turn the AC on and off and see how much it impacts the estimated EV range. Other variables include hills, outside temp, and how hard you tend to accelerate.

Some people drive 50 miles per gallon of gas and some drive 65 on that same gallon. EV range is the same way. Some people drive 15 miles on 2.5 kwh of power and some drive 8 miles on that same charge.

Turn off your AC and drive down hill. You will get 15 miles of EV range.

 

hey, if your dealer agrees there is something wrong, that's great. they usually blow you off and say it's normal. let's see what they come up with, let us know as soon as you hear, we're all anxious to know!

 

I watched mine decline as I drove more on the highway in HV mode. It gave the impression capacity was somehow being lost each recharge. In reality, it was just the EV estimate value influenced by previous driving data. Now mine is up higher than ever, not having taken a long trip recently.

Actual EV driving distance hasn't actually change. It's been consistent throughout, despite the estimate going up & down.

It reminds me of the reaction Prius owners had throughout the Iconic years. When the battery-level dropped to 2 bars, that change to pink on the screen made them panic. They truly thought something was wrong. A few even took desperate measures, not realizing that was perfectly normal. Everything is fine. They certainly don't feel that way seeing it though.

This is unquestionably the "panic" situation for new PHV owners.

 

The number is NOT a direct relation to full charge. If you go up a hill it takes more KWH to go up that hill therefore if you always go up a hill for 6 miles a day, you're likely going to have an extremely low EV miles estimate even at a full charge. When I got my car it was at 13.3. then 12 then 11.9 11.6, and all the way down to 9.6. But then i started to drive more efficiently, engage the engine going up hills and use the EV at lower speeds, and now my estimated range is back up to 11.9 miles. You have to understand the full charge miles is NOT an absolute measure, but instead the result of an algorithm based on driving habits. If you had something like a scangauge that measured total KWH or State of Charge of the battery, THEN you could say THAT was an absolute representation, but the miles ARE NOT.

 

hi bill3888, did you take your car in yesterday? i'm curious to find out what they say. you sound frustrated and i completely understand, this is all very confusing! i hope they can repair it for you, all the best!

 

I think you mean 2.8 kWh charge, assuming you are talking about the Prius Plug-in.

 

Unforunately, a kWh gauge wouldn't work either.

14.1 miles had been my record EV distance until recently, when the hot summer mornings arrived.

Although the EV estimate stated 13.7 miles yesterday, I actually traveled 15 miles of EV with 2 miles remaining when I arrived at work. It was 84°F degrees that morning, quite a bit higher than the usual mid-60's.

Today, it was 77°F and I was curious as heck how far I'd be able to travel in EV. So, I refrained from the usual HV button push to warm-up the engine during the most efficient portion of my drive. 17.2 miles later, I was in the parking ramp with 0.3 miles of EV still left. The entire commute was with electricity, even though the EV estimate stated only 13.7 miles were available.

In short, YEVWV is the new term we'll have to learn to accept. Your EV Will Vary, based upon acceleration demand, cabin comfort, window clearing, and outside temperature. There's simply no way to accurately depict expectations.
