I'm not sure if you saw this reply from [USER=7530]@EvanstonI3[/USER] (https://www.mybmwi3.com/threads/using-range-extender-only-for-electric-charge.3590/page-2#post-77663) on your previous post, but AC charging is really your only practical at home solution. DC charging is mainly what you'll use while out and about at Electrify America, EVGo, Chargepoint, etc.I'm not sure what you mean by "partially charged 3 times." Was that out during the drive? AC (slow) or DC (the two extra pins you identified in the previous thread)?AC charging comes at various rates from the 1.0 kW rate of the slowest level 1 EVSE to 7.7 kW rate of a level 2 unit allowing 32 amps into the car. That's the difference between 2 1⁄2 days vs. 8 hours from empty to full. But if your 2015 is severely battery-degraded, then it's possible the reduced range makes the car impractical, even starting at 100%.
