Mark, Jack,

I can confirm that the charging bit is not set when pre-heating the battery.
It's only set when it goes from pre-heating to charging.

Maybe we should just look at the State (0x95) instead of charging bit 
(0x96) and state.

I have uploaded my logfiles fom when i did the test here:

Inside the rar archive are two logfiles, one pre-heats till 49% then i 
press stop from the VDS.
The otherone pre-heats till 100%, and then the charging begins.

Note that the "preparing to charge" state is also entered after the 
pre-heating ended and before the actual charging starts.

If possible, check up on it with an App during the charge (when an App is connected, the car reports in once every minute - otherwise only once every ten minutes). I have a full log running on the development server at the moment, and 1.2.0 code sends the detailed charging bytes as well as the summary status text.
