Agree with pretty much everything plus two more:
The backup camera should have lines showing where the car is going just like the backup camera in my LEAF! And it would be nice if you could completely stop outside air from coming into through the vents when the Heater/AC are off.

Good point. Long live the RAV2!

- No external reverse beeping noise (like some large SUVs) or courtesy "look out!" mini-honk button (like the Volt).

Which large conventional SUVs have this? I've driven my fair share of them and never have heard an external backup buzzer except on the F-350s one can rent from Home Depot.

- If I don't drive the Rav4EV for a couple of weeks, the 12-volt battery dies and the car won't start, even if the main battery is fully charged.

This happens with conventional vehicles, too. Buck up and buy a battery tender for the 12V system if you truly don't drive it for a few weeks at a stretch.

- No way to force the brightness of the screen to night or day mode regardless of exterior light conditions. I can set it so it's dark at night and bright during the day, but manually turning on the headlights should change the car to night mode (or there should be another way to do that).

Hmm. This could irritate me, as I run with headlights on 24/7 and manually change the dashboard brightness on my current vehicles.

Replace it, as TonyWilliams has already done per his signature! New horns are cheap, and even if you have to add a relay the installation is pretty simple. 12V systems are 12V systems regardless of the main propulsion method of the vehicle.

Re: Fast charging. Just like the entry level Tesla Model S with 40kWh battery pack, neither have fast charging capability because the batteries cannot take fast charging.

I was going to post that the 40 kWh Model S (whenever it appears) won't have Supercharging ability, but you saved me the trouble.

At least they put a large 240VAC charger on board, unlike the Leaf and Spark EV.


Note that the 2013 Leaf SV and SL have a 6.6 kW (or 6.0, depending on who you trust) on-board charger now.

The batteries can take "fast charging", but Tesla doesn't offer it on the 40kWh battery car. Currently, the 85kWh pack on a Tesla is charged at about 1C, and about 2C on a LEAF (with a tiny 24kWh battery).

Quote:
The 60kWh pack (actual >66kWh), charging at 90kW charges at a 40 minute rate (1.5C rate). Charging our packs (or the 40kWh Model S) would mean a 2C rate (30 minutes) which probably damages the batteries cycle life, which would be unacceptable.


News flash... you don't have any idea what rate a non-existent car might ask for. If Tesla determines they only want a 1C rate, the car will tell the charger to give it 1C. You're making an assumption that the charger can't be controlled, and that would be a bad assumption. Edit: I see you then argue exactly that... oh vey!

Quote:
but this would also require the new fast charging SAE plug that is currently only being used GM Spark EV.


The SAE "Frankenplug" will be used by the Spark and BMW i3. Why on God's earth would you assume the Rav4 would require this, or any other charger? We're actually working on a CHAdeMO plug right now, since that's what's out there. I have no desire to chase the Frankenplug dream.

The primary difference between CHAdeMO and Frankenplug is the communications method. The former uses CAN bus signals, and the latter uses PLC.

Quote:
At the time the RAV4EV was being designed, the SAE dual fast charging connector and Tesla Fast Charging Network was still in the process of being deployed, so it was easier to just shelve fast charging design issues for this small run of vehicles. At least they put a large 240VAC charger on board, unlike the Leaf and Spark EV.


Uh, there's a lot of imagination in your charger knowledge. :ugeek:

Re: that, I have no Rav4 EV, but I think it's got to have it. They became mandated (in one form or another) years ago, I believe w/model year 2007. It just might not have anything to display the tire pressures, only to provide a warning.

Yep! It's just an idiot light, but I quite agree, nowadays, there ***should be*** a digital readout of each tire accurate to within +/-1psi. For ANY car in this price range, a digital readout should be mandatory! This is a useful feature, and a very effective SAFETY feature at that!

Why do you think that the 18650 Panasonic cells can take "fast charging"? They were designed to accept a 2-5 hour charge rate. I assume Tesla thinks they can take an occasional 1 hour partial charge without much of a negative long term effect. Do you know why the 40kWh Tesla won't be Supercharger network capable?

Also, I haven't tried it myself, but someone else on the forum pointed out that holding down the home button turns off the radio.
Holding down the Home button turns off the entire Infotainment system, not just the radio. That's a nuclear solution! Granted, pressing the Home button again after turning off the entire system will turn on everything but the radio, so this can be useful even though it's not perfect.

One thing I noticed is that when you turn the car off the radio turns off as well. Most newer cars I've driven including the Volt keeps the radio on for some length of time after the car is turned off. The question I have is do you use any more power parked with the Rav4 on assuming no climate control and no use of the brakes or steering verse turning it off and then back on in accessory mode?

Regarding the 12V battery going dead, anyone know how much current is required to jump start the Rav4. Obviously you do not need to turn over a starter. I imagine you could build a very small jumper battery that can provide just enough power to initialize the computer and close the relay to start the car.

I would say the bolded part is not true. The behavior you mention is a GM thing. I've seen it on many/most GM rentals. I've not observed on newer non-GM cars. Can you name any non-GM "newer cars" that do this?

Well of course the bold part is true as i said cars I've driven ;) . My MINI has this feature. Most cars I have rented do as well, but they were all probably Ford or GM vehicles and maybe a few Kias. Nonetheless it was something I noticed and my question on power use remains.

This feature is on more than just GM cars. Foreign cars tend not to have power after shut-off while many American cars do. There are always exceptions to the rule in both cases. Japanese cars, for the most part, turn off everything - including the phone (if you're on a Bluetooth call it gets cut off), cell phone charging, and windows; but I think Lexus is an exception to that rule...not 100% sure, though.
