Any update on the Gidometer for the RAV?

According to Phil, there is an ethernet port on the box in the trunk. Conveniently, there is a power outlet (cigarette lighter right there). I would think the best way to do a gidometer is to add a router with wireless capability via the ethernet port to the box. Then add a wireless display to show the SOC. However, one need to decode the CAN bus (which is in the box where the proposed router is connected to).


My plan was a simple twisted pair fished from the rear mounted Tesla communications box to the dash area. But, you method certainly has merit. I could watch SOC from any computer anywhere in the world!

Sorry, I haven't worked on it at all. We have a OPENevse workshop coming up Feb 9, so maybe we'll look at it then.

My house is being painted this week, and I also decided to clean out the garage, paint the floor, install more charge stations, add lighting, blah, blah, blah.

I'll bet the SO is happy that some of her "Honeydo" projects are getting done.

Has anyone played around with the OBD II port on the Rav4 EV? A lot of the stuff one normally sees there is ICE-engine oriented. Has anyone plugged a monitor in to see what the Rav4 does while you're driving it?

(I'm tempted to get a monitor just to try it out but the Rav4 is the only vehicle i own new enough to have an OBD II port, so if there's nothing useful there, it'd be silly...)

There are no standard PIDs on the front (Toyota) OBD port. Everything is Toyota proprietary. Because there are no emissions, there are no requirements to provide the standard PIDs.

Hi Tony... Have you had any time to make progress on this effort? I'm not planning to renew the Safety Connect subscription, but would love to see SoC and get charge completion notifications. A data-logging device connected to a hotspot or cellular-tether device would be a perfect solution.

Sorry, but I haven't had time to commercialize this.

I understand. You mentioned in your post three years ago that you are willing to share all knowledge. Assuming you have something worth sharing, are you still willing to do so? Thanks!

Hi all-

I'm hoping some folks are still following this thread and might have some input. I'm a newer Rav4 EV owner, and for the last few weeks I've been poking through CAN data that I've logged from both the Toyota and Tesla buses. Fortunately many of the Model S decodes scattered around the 'net are the same or adaptable to our Rav's.

Is anyone else working on decoding these messages? I haven't found any threads in the forums here yet. Personally I'd like to develop a small display screen to provide me with a real-time display of volts, amps, kW, remaining kWhr, pack temp, min/max cell voltage, etc.

-Matt

I am waiting for a Panda OBDII reader from Comma AI which will give me access to all the databuses. I've heard it is easy to decrypt the proprietary data and will have a go at doing so.
