Triple Amps while charging at home?

[kazenodoragon]

Usually when I plug my car into our 110v at home, the app says it is charging at 1 kW and 12/12 A. However, this time it said it was charging at 4 kW and there was a circled number 3 in front of the 12/12 A.

Does anyone know what that number 3 means, and if that 4 kW could have been accurate?

The circled 3 indicates the car thinks it's connected to 3-phase power, which would provide a lot more power at 12A/phase. The 4kW charging would be possible on 3-phase power. Knowing you're in Austin however, I think it's highly unlikely you have 3-phase connectivity, so my question would be: "why does the car think you're connected to 3-phase power?"

North American cars don't have 3-phase inlets or 3 phase chargers; it's physically impossible to feed 3 phases into a NA car. This is a weird software bug; others have reported it:
