Yeah, it's a shame we have no easy way to check the battery integrity. Best you can do is see how much energy you can put into it on multiple occasions. I'm sorry you didn't feel comfortable with that unit. It may have been fine. It sounds fine from what you described, but it is your investment. Good luck to you on your search for a replacement.



RAV4 EV battery degradation
Make sure that the battery is at room temperature, then:

1) Fully charge vehicle (extended) with the J1772 port (not CHAdeMO)
2) Battery must be near room temperature
3) Turn off cabin climate control with "OFF" button
4) Disconnect the 12 volt battery negative cables and leave off for several hours minimum (overnight is ideal)

Next day:

5) Reconnect 12 volt battery
6) Hold foot on brake and press START button with key fob nearby
7) Energy gauge will show Full (16 illuminated segments) and "LO" on the GOM
8) Wait for navigation unit to complete its start up
9) Press START with brake pedal depressed a second time
10) The displayed range is "RATED RANGE" at 3.5 miles per kWh

11) Divide this Rated Range by 146 to get usable battery capacity compared to new.

Example: 142 rated range / 146 = 97.2% battery capacity from new

********

If you drive the RAV4 EV at my standard test speed of 100km / 62mph ground speed, it will go almost EXACTLY the rated range.

TEST DRIVING PROTOCOL - dry, hard surface level road with no wind or cabin climate control with new condition battery at 70F, no elevation changes, "out-and-back" or loop course to compensate for any wind, 62mph / 100km/h GROUND speed as measured by GPS.

So, if the car is new, it will bang out 146 miles and the rated range will be 146 under the prescribed conditions.

If the rated range is 135, it will go 135.


Just when it seemed all was clear I see this: http://sfbay.craigslist.org/eby/cto/5054201548.html Check out the GOM 154!!!!!!

I can not imagine any way to get a readout like that short of doing the Tony Williams test then driving at like 20 MPH to build a new but ludicrously low speed profile.

Well they didn't drive for long: 13 miles on the odometer?? That car was bought but never used. Weird.

The ad says 8k miles. The pictures are likely either when the car was new or dealer photos of a similar vehicle.

Hello, I have had my 2014 Rav EV since January 2015. I have been charging my car with no problems until recently. I used to get charge up to 120 miles on the extended battery setting. Now, the most I am getting is 90. Why is this happening? Is there a way to make this more predictable? Thank you.

The reduced range shown does not indicate a charging problem. It indicates that your driving efficiency has been reduced recently.

I am seeing a similar result after since having the recall firmware installed.
