The EVSE you use to charge the RAV4 does not influence the range of the vehicle, assuming there is time for that EVSE to provide a full charge.

The RAV4 EV has an EPA-rated range of just 103 miles new, and the GOM is just an estimate of the number of miles you can drive. While many/most of us can easily get more than 130 miles out of a full charge with a RAV in various driving conditions, there is no guarantee either that the GOM will be accurate (ie, the GOM can read 110 after an extended charge based on previous trips, yet you can still drive 130+ miles on that full charge), or that you will even get that sort of range given driving conditions, your driving style, or the prior use of the battery.

There is no connection between charging speed and vehicle range with a full charge. None.

You are confusing the GOM readout with range of the Rav4 EV, and formthat, there is no connection between what the GOM calculates based on previous driving and what i will actually be able to drive in the future.

The GOM can read any number; please understand this, absolutely ANY NUMBER, but if the Rav4 EV is fully charged, and the vehicle is in new condition (no battery degradtion), and ambient temperature is about 70F, then on a level, no wind, dry roadway, without climate control, then the Rav4 EV will travel 142 miles at 65mph.

Again, GOM can read ANY number, and the car will go 142 miles at 65mph.

Just a heads up, cars with a bad inverter/heater will have some funky readings on the gom. You can tell as the spread between ac on and off are huge

I reported that I got 165 miles on a single charge the other day. Tony said he had only managed 151.8 so I decided to double check. I drove all over Amherst mass dumpster diving with a homeless friend. Loaded the back with detritious from an evicted gamer then drove to Northampton to catch the end of the gay pride march. I then said go for it and drove to Putney Vermont and back. Bottom line just before the end but before the turtle showed I quit at 175.1
I traveled numbered state highways at normal speeds 30- 55 . The temperature was 65 degrees. One of these days I will work on squeezing out 200. Having fun in my old age.

The next morning after a full extended charge the GOM showed 160

this implies that you were achieving close to 4.0 miles/kwh. (the GOM at full extended charge is reading whatever 41.8KWH converts into.
160/41.8 = 3.82 mi/kwh.

Which is definately achievable at the speeds you mention on mostly level terrain on a battery with no degredation.

I've gotten 3.9 mi/kwh on a 110 mile trip but i cheated and was going net downhill :-) (about 3000' over the 110 miles).

One of the barriers to getting really long ranges is driving on Freeways. The Rav4EV just isnt that aerodynamic, so if you drive at 60+ you're going to get a lot less miles really quickly. (I actually got down around 2.1 mi/kwh on one 20 mile trip once, by driving 85mph the whole way. This was not in evil-red-car mode either, just regular blue-car mode, but really fast. Milpitas Motor Speedway for the win.)

Yes for the whole trip that was 175.1 the reading was 4.4. Miles per kWh . A warm day 65 and reasonable speeds

Just brought my new RAV EV home last night.
Couple of issues. Left Dealer fully charged... Showed 123 miles. the gauge showed full. at around 98 miles - the number dropped down to 60?
Did a full charge last night and once again - 10 miles of conservative driving today and the meter dropped from 90 to 58, but the gauge still remained near 3/4 or above? Any ideas?

Also, driving today with the window down, my wife noticed a click e clack sound coming from the two right tires. Almost sounded like horseshoes?
Thougts?

The mileage drop may be the computer adjusting to your driving style.

The tire sound is not normal. I would take outback to your dealer ASAP.

That kind of mileage drop while driving doesn't sound typical to me. What you will see is your total range starting out lower after a full charge, especially when you top off the battery. It worried me until I went on some heavy use days and finished the day with about 10 miles range left and whaddya know, the range popped back up the next morning after a full charge. They don't call it the GOM for no reason.
