The Rav4 EV pack is almost exactly half the size of the Tesla 85kWh one. Actually, i might be fooled to think it is exactly half, except i think they used 2900ma cells, vice 3100ma.
When the car is fully charged, the cells (i don't know if this is individual, or groups of parallel cells) are 4.1 volts. At the "normal" charge of about 90%, the cells are about 4.05 volts. This, by the way, is exactly the voltages that the Nissan LEAF uses.
I drove tonight about 75 miles from Orange County to San Diego. I started around 54% SOC, with cells around 3.7 volts. I drove the car all the way to "Turtle", which occurred at 2.9% SOC. I continued to drive the car to 2.4% SOC, but the battery contactors did not open and i was in my garage.
For the 75 miles, the car reported that I used 21.993kWh, and regenerated 889kWh, for a net of 21.104kWh (yes, it actually gives all three values).
The cell voltages sagged significantly between 2.8xx volts and 3.2xx volts while driving at this low SOC%, entirely dependent on load. Once in my garage at 2.4% SOC, the cells reported 2.930 volts low to 3.122 volts high under no load.
We are compiling all the data as part of our "JdeMO" project, to offer CHAdeMO quick charging to Rav4 EV, Mercedes B-Class ED, and Tesla Model S (no adaptor required!).
More tidbits:
Low Battery Warning - 19.3% SOC
Very Low Battery - 13.9% SOC
Flashing gas can - 11.9% SOC
"LO" on the GOM - 8.4% (NOTE: cell voltages 3100-3190ma)
Climate Control Limited - 7%
Turtle - 2.9%
No cutoff by 2.4%
