I think I recall reading that Teslas do this too. I get the impression that EV mechanics are supposed to disable the HV battery unless they're specifically working on the drive system and need to have it active. I suppose it's like electricians locking out circuits they're working. Now whether the mechanics actually DO that, any more than most electricians actually lock out circuits, I couldn't say. Many years ago, in my Honda conversion, I connected the DC:DC to always float-charge the house battery. That decision bit me in the tail when I put the car in storage for several months, and carelessly neglected to open the main breaker. I would hope that with all the computer power they have on board, modern production EVs are smart enough to stop trying to charge the house battery when it's obviously unable to accept a charge, or when the traction battery is getting low on charge.
