I have built multiple EV conversions and used DC charging.
- AC is easier to start with
- DC charging protocols you need to communicate & negotiate with the rapid charger in the street
- There is no reason why you couldn't DC charge any conversion in principle, just comes down to time & effort
If you want to read more, AC is J1772 and is just a voltage dividing resistor with some PWM

For DC there are two (three?) protocols
- ChaDeMo is being phased out despite being the best one (V2G & simplicity of use)
- CCS2 is what the big manufacturers have come up with and it is hilariously complicated. My friend Uwe developed the FOCCCI project that has reverse engineered it
- In the US Tesla are using NACS (not sure on the details)
I am recording a video series where I illuminate the tech behind EVs, charging and energy, you can find it in my submissions.
- pornel 2y agoNACS uses the CCS protocol, which makes dumb adapters possible.
