I meant from the CAN bus point of view. The original documentation for this had:
ID 100, B1=0x95, B2=0x01 charge mode is “charging”
ID 100, B1=0x95, B2=0x02 charge mode is "topoff"
One of my old can bus dumps (labelled 20120218.charge.topoff.crtd) shows this:
5193698.348 R11 100 95 4 1 64 57 2 E 2
5193706.208 R11 100 95 D A 64 57 2 E 2
5193709.798 R11 100 95 1 5 64 57 2 E 2
5193918.339 R11 100 95 4 9 64 57 2 E 2
(duplicates removed, for clarity)
That is 0x04 -> 0x0d -> 0x01 -> 0x04 (done -> preparing -> charging -> done). No ‘topoff’. In fact a search for ‘100 95 2’ (or ‘100 95 02’) doesn’t match anything in any logs I have.
So perhaps, it doesn’t exist or is a Tesla Roadster 1.5 only thing? Or maybe it is that car automatically tops itself off after 24 hours of being plugged in?
