Focus Electric HACK CAN ID

Sat Jan 04, 2020 3:57 am

Will I find someone here who would like to build a document describing the CAN ID and individual Bytes that are on the CAN bus? This will allow further modifications ... unlimited.

I share some of the CAN IDs found and decrypted.

Then you can build projects for arudino, display data on additional devices (cell voltage, battery capacity, charging speed expressed in A or kW ...).

Modifications will allow you to insert a charger from 3 phases, e.g. from Tesla, start charging CHAdeMO or battery capacity with additional cells.

I use translator. Sorry for the mistakes.

Wow nice work. Someday when I can find parts cheap enough I want to build a higher capacity battery pack. I guess that means I will have to learn about CAN bus and how to use it someday.

I suppose with a larger pack adding CSS charging capability would also be nice to have.
