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.

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.

Hello Sebuś,

I will be receiving my FFE next week, so I have not begun to tap into the vehicle's CAN system to start reverse engineering it yet.
I have some background with Honda's CAN system, but not with Ford's.

To get things started off and to get up to speed, can you share what hardware/software you're currently using to record you CAN logs and submit your SID22 requests?

I'm excited about where this CAN lead (pun intended :) )

Also, is that your modified FFE in the picture? Are you already adapting Tesla parts into your FFE?

Pictured is my Ford. Tesla charger was developed by my colleague who is also in this forum. My job is breaking CAN in Ford. Currently working on an additional display - it will show the value of 1 cell, min, max, avg, charging power, load A, regen in A, battery temperature, charger, etc.

Where are you from? Do you want to cooperate?

Hey Sebuś
I would love to collaborate. I am from Ohio in the United States.
Good job on the Tesla Charger. I will have to search for details in the forum. I'm new to the forum and have some catching up to do on what all has been done to the FFE so far.
