Hi Guys/Gals!
I've had an idea floating around in my head the last few days. I've been thinking about using a microcontroller like the Arduino wired into the Rav4 EV to monitor various parameters and then upload them to an FTP server via WiFi. I was thinking of having several thermocouples or thermistors to monitor temps of various components or cooling lines although I haven't even looked into what is accessible or how I would attach the appropriate temperature monitoring device. Other things that would be of interest would be voltage and current flows (with current transformers), but again I haven't really put any thought into this especially with the three phase power and the capability of the analog ins of these microcontrollers. I think someone else here might have mentioned this but when plugged in even having a voltage and current monitor for charging with LCD display would be helpful. The thought was that with a WiFi connection it could check for your home WiFi signal every time the car was turned off and then upload the logged data.
Anyway, I have fairly limited experience with this type of programming or assembling prototype electronics but it is something I think I could do given enough time (which I don't have a whole lot of unfortunately), but I thought it would be good to start a discussion on what are the types of things we would want to monitor and how we would do it. I'm sure there are a lot of people on this board who have more direct experience with these type of things than myself and would like to get other's input on what is possible.
