Off topic: what would it take to modify an i3 to take a tesla charger ? To be clear, i do not mean using an adapter. I referring to the most recent announcements of make OEM's switching over and the SAE adopting the tesla port as standard. Thanks.
I am learning more about the NACS connectors, but upon first review, the positives are that the NACS uses the same CCS protocols for communication. The negatives (with regard to upgrading) is that the AC and DC charging are on the same pins, so a contactor relay would need to be added to both isolate and divert incoming AC or DC power to the proper locations (and some control software or added microcontroller to add a handshake/set the internal contactors correctly). The button on the NACS communicates by wireless signal to the car to open the charging door, CCS doesn't have this in the standard (to my knowledge). To make matters worse, when I tried to use the "Magic Dock" Tesla superchargers (see the video), I had issues upon disconnecting that caused a drive train fault code which I could not reset with the bimmercode app, requiring a costly trip to the dealer. I suppose wiring it to DC only for use on superchargers would be easier, but I would not recommend that either. Anyways, this is an interesting topic, especially with so many car companies adopting the NACS and SAE also agreeing to review it as a national standard just a few days ago. Thanks for the comment!
I have a 2018 i3. Should I charge it to 100% or some lower number when charging at home? I read an i3 blog where one user said BMW engineered head room in the charging capacity and thus it is to be charged to 100. Headroom meaning that 100% isn't really 100 but in actuality less. What is your knowledge on this matter?
Yes that is correct. You do not have full use of the battery like Tesla batteries. The BMS is very good on these vehicles so battery degradation should be minimal. I only have less than 10% degradation on 2017 with 60k miles.
