A VCU can mean many things, but for the purposes of this page, a VCU means any programmable 12V controller that is designed or found to be useful in an EV conversion.


VCU Comparison TODO:
While "Primary use case" tells you what these controllers are intended for, the other fields tell you what they're capable of when configured or re-programmed for your use case.


- Add outlander vcu
In the spirit of open source, controllers with open source features are added leftmost on the table.
- Add johu's vcu
- Fill in missing info
- Add links

A VCU can mean many things, but for the purposes of this page, a VCU means any programmable 12V controller that is designed or found to be useful in an EV conversion.

While "Primary use case" tells you what these controllers are intended for, the other fields tell you what they're capable of when configured or re-programmed for your use case.

In the spirit of open source, controllers with open source features are added leftmost on the table.

To-do

Add open source VCUs:

Add closed source VCUs:
