Revision as of 13:08, 18 January 2023
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.
In the spirit of open source, controllers with open source features are added leftmost on the table.
To-do
- Add other VCUs that have been used by people on the openinverter forums
- Fill in missing info
- Add links
Add open source VCUs:
- johu's stm32-car (https://github.com/jsphuebner/stm32-car)
Add closed source VCUs:
- AEM VCU200 and VCU300
- Engovis EVS-VCU
- Thunderstruck VCU
