BYD Atto 3

  • Vehicle Type: ATTO3
  • Log tag: v-atto3
  • Maintainers: Alan Harper

The testing and development was done on an Australian right hand drive Atto 3 but would expect it to be the same for other countries versions (including the Yuan Plus), and may work on the Dolphin too.

Most of this data has been reverse engineered and is based on a lot of assumptions and guess work, and would be interested in reports for non CCS2 cars as well as left hand drive in terms of which doors are open

Charge port door

The charge port door is reported as open when charge is in progress or waiting for scheduled charge, however the car doesn’t appear to report this, and is only done so the iOS app does show charging status correctly

Physical mounting

I have had success with attaching the OVMS hardware behind the fuse panel cover and attaching the GPS antenna to a piece of metal higher up behind the fuse panel cover
