The software is such, that it is intended to keep your high-voltage battery level constant. The engine will run full-time, pushing energy to your battery at a level equivalent to the amount of energy you’re pulling out of your battery. Hope this helps.
This sounds fairly normal, however you may have a high voltage battery that is beginning to fail. It is very difficult to tell from just a few messages on FiskerBuzz. Feel free to reach out directly if we can be of any help.
