Predicted EV Range Down

For the past month or so, I’ve seen the Toyota Guess-O-Tron’s EV range go down. In early-to-mid-April, it dropped from about 30 miles or so to ~28 miles. A couple days ago it dropped again to ~25ish.

The interesting part though is that the *actual* range does *not* appear to have reduced much, and all in all its estimates are probably more accurate now. I’m seeing about the same number of miles left after each leg of my daily, ~19-mile commute.

The actual range probably has gone down a *little* bit though just because of slightly greater air-conditioner load (I usually keep it at 80ish though, so probably not a huge impact).

Anybody else seeing anything similar on your P.Primes?

 

Yes, that’s probably a big piece of it.

I find it … wacky ... that it gives me a low climate-control score when I turn off the A/C and set it on “LO,” which of course shuts climate control off completely, so it should be the best possible score...

 

Curiously, I’ve only once seen the prediction change as I turn the A/C on or off. However, I have seen the number in the app somewhat higher than that on the dashboard, as if the app were accounting for air conditioning and the app’s number not.

 

I don’t know numerical scores, and I haven’t run it at full blast long enough to show the numerical score.

However, as I adjust the temperature, it displays a five-dot indicator of how much energy it will burn. It goes up as I turn the temperature down regardless of whether the A/C is on or off.

Sometimes, as I turn off the engine and it gives me my score, it says to choose a more-moderate temperature, even with the A/C turned off.

 

Yah know, I’m not so sure anymore that the *actual* range has not gone down. In fact, it may be down considerably.

Today, charging at work, it only charged just over 5KWh. I’m pretty sure I’ve historically seen ~5.8KWh (plus or minus 200Wh or so) on a pretty-much “empty” battery (down to HV threshold).

Actually, I had noticed lower numbers earlier, but those times, I had some residual charge (so hard to tell).

This upcoming weekend, I’ll be taking a certain trip that has historically consumed almost exactly one battery’s charge. I’ll see if it fits anymore.

Perhaps, with outdoor temperatures rising (and we’re talking Texas here, so highs in the high-30s Celsius), Toyota is intentionally reducing the total charge of o keep from impairing battery life. In other words, increasing the charging margin at the top.

 

That would be an interesting comparison, although if there’s an elevation change on your commute, that could confuse the results. Traffic conditions potentially as well.
