Re: Aftermarket charge to 80%, opinions wanted!

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.

Yes, that's a key question. Non-factory type of re-flashing of any ECU/module provides Nissan/dealers a basis to void warranties.
67% would be great. That would add 5 seconds to the programming time, right?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.

The cycle time may need to get longer if there is any processing or other lag time inherent in the implementation though.

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!
