This guy in Holland did what I’d wanted to do last year, add a CHAdeMO port to his DIY conversion EV. We see here a VW Bus (I had a Karmann Ghia) that’s been converted to electric drive (as has been done with many other VW bus’s). Working with the Orion BMS guys he added CHAdeMO support. In this video he takes it to a Fastned station and gets about a 30 kw charge rate.
