My beautiful RAV4 EV 2014 was involved in a head on collision. It protected me except for broken hand so I had to look into the used market. The good news is there are a ton of them coming early off lease after people have exhausted tax credits and decided range issues were a problem. Buyer beware that the battery was not abused. My test is to drop the battery to about 15 miles and measure how much it will take to refill. I bought a 2014 first leased in 7/14. 14k miles...$35k from Carmax with a 5 day return policy so I could check battery. My Juicebox gives me exact numbers on KWHrs. I showed 40.7 KWHrs with 17 miles left when I started so I figure that was about 5-6 KWHrs at the start and I did extended charge. I suspect 2-3KWHrs went to battery heating as the night was cold. 48F
Anyone have any comments? Like my test?
My 2014 was also sold to an insurance "total" owner. I still have my 2012 available.
The JuiceBox meter is known to be inaccurate by a fair margin. I would not use it for this type of test.
I seriously doubt your 2014 car would have much degradation at all, and it's a bit difficult to "abuse" the battery. In other words, if the battery is operating as designed, it's fine.
A new condition battery should take 50kWh to fill from depleted at room temperature with a 30 amp charge rate (yes, I measured it).
RAV4 EV battery degradation test
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.
