new battery for Ford focus electric for 55 kWh

[ivankovff]

I have done a new battery for my Ford focus electric for 55 kWh instead of 23 kWh initially. And I have a little inconvenience now that the car doesn't read correctly all new kWh and it is impossible to see probable millage. My firs test drive was for 240 km and I used only 30 kWh then the car was blocked. I think that the configuration BECM from the car of 33 kWh can solve the problem. Can someone share with me the file of configuration for the car 33 kWh ?

Please share the details of your new battery. I intend to build a new one myself some day.

I'm not ready to share the information because I did not yet finalized the work and now is a test period for eventual failures. That's why I do need urgently the configuration of BECM module for a 33.5 kWh Ford focus electric car. Now I have to control the whole period of charging and to verify all parameters in real time while driving.

I'd love to help but I wouldn't even know where to start. I'm handy with electronics but don't know how any of the module programming works.

What data frames are we talking about? Something like SavvyCAN could capture raw frames from an OBD adapter but you'd want to know what to filter for. Otherwise those captures get BIG fast.

If you have a car with a battery for 33 kWh and you have forscan loaded in your computer I can explain how you can read BECM configuration.

guide how to read BECM configuration:
1. forscan should be loaded on the computer with extended license even temporary (it is free of charge)
2. you need to connect forscan to the car
3. option 'configuration'. I have circled it with red on the photo added and press 'read the BECM configuration' also circled in red

4. while reading a file of configuration will open and you should save it on the computer
5. after saving the file you should end reading

ivankovff,

I don't but it looks like Hemia has what you are looking for. I have a 23 kWh 2014 FFE and if or when my battery dies, my FFE will be a project car that I try to build my own battery. My biggest problem will be that I have I have zero experience with CANbus and don't know electronically what I would need to do to not have the car complain about the original battery modules not being there. Be it emulating the missing modules or what not.

 

[ivankovff]

Good day
I finally have the results.
The configuration with Focus electric 33 kWh did not help.
I realized it through Can-bridge.
However, It took me 5 months to achieve the stage that the car accept new battery and did not block.
It turns out that I spent more time on programming the car than on constructing a new battery for the Focus Electric

Here is a video from my channel about the new battery
