[Ovmsdev] Nissan Leaf breaking changes

[Mark Webb-Johnson]

There are a handful of people I have heard from using the Leaf code, but I don’t know of anyone developing for it at the moment.

There was a lot of discussion a year or so ago about which can bus to work from on the Leaf. Consensus was the EV bus. From my memory, the reasons were:

We can use passive listening to see if the car is charging, driving or sleeping.
Active polling is bi-directional, but if car is sleeping, polling causes vehicle to use a 12V solenoid to power up a controller each time, and we are worried about wear-and-tear as well as 12V battery consumption for those components.
The EV bus has lots of stuff available on it.

A search for Nissan Leaf in the archives would probably bring up all the gory details.

Regards, Mark.
