One last suggestion/lobbying effort. Make the lowest limit 70% rather than 75%, if that isn't too difficult. It will matter in hot weather.

If the SOC or capacity bars are to be used as indicators, it makes sense to stick with the corresponding charge levels - 100, 92, 83, 75, 67, 58, 50.
It only takes a second to get into the "set max charge bars" mode. It seems to me that you'd show 12 bars, then 11, etc changing every second or so. You let the button go when the desired number of bars are showing. So adding another level is only one more second, and only if you need to go that far. Of course, if you overshoot, then you have to go "round the loop" again, for another 6 seconds or so.LeftieBiker said:67% would be great. That would add 5 seconds to the programming time, right?
Titanium48 said:5 seconds is probably a bit longer than necessary, but a one second cycle time would be too fast for many people to reliably choose the option they wanted. The cycle time may need to get longer if there is any processing or other lag time inherent in the implementation though.
Dala said:Wow, thanks for all the feedback! And yeah, this is mainly for the 30/40/62kWh upgrades, that you really want to protect your battery after investing in a costly battery upgrade. This should be especially beneficial for the 40kWh pack that charges to 4.20V per cell, which is quite high SOC (compared to 4.13V on 24kWh packs).
For the initial version, I'll add 4 different charge settings, (75, 84, 92, 100). I personally feel that if you go lower than this you'll risk limiting your use of the car.
I'll try to use the cruise control cancel button, and this menu is accessed by holding it for longer than 1second. Then depending on how long you hold the button, you'll set the max charge %.
I'll use the capacity bars to temporarily show the max charging %, I'll post a video when I have it working.
Thanks for all the feedback and great ideas!
Yes, especially given the occasional hiccup that requires replugging the charging cable. I would probably forget to reset the limit if its duration were only one charging session.LeftieBiker said:How hard would it be to make this a default setting that you change only when needed, instead of every time you want less than 100%? You'd only need to go into the menu to change the default.
Dala said:First version is up and working. I had to make some sacrifices in the activation, turns out the steering wheel buttons aren't on the EV-can. So only available info is the HVAC system. I settled on this precondition, recirculation ON and fanspeed at max (7). I chose this combo since it's so unlikely that anyone would ever set it like this.

Here v1.0 in action.

Next step is to add longer delays (was tricky to set correctly with 1s delay), charge options all the way down to 50%, and make the dash charge% represent which selection you finally landed on (since it can be hard with only the capacity bars).
Thoughts?

Question; I toggle defrost on and manually adjust to max fan speed all the time. Usually run it 20 seconds to a minute or whatever it takes then turn off and close vent. Closed vent is my normal operation. I am thinking this would not change setting?
Thank you I made the code open source so anyone can suggest improvements or make their own based on it.LeftieBiker said:That looks great!
