400V is hardly the limit… Anyway, if you’re just interested in big connectors/cables MCS targets up to 3.75 multi megawatts for commercial vehicles. https://en.wikipedia.org/wiki/Megawatt_Charging_System https://en.wikipedia.org/wiki/Megawatt_Charging_System Though 3.7MW is mostly theoretical there’s already 700kw chargers in the wild. The cables end up thick, but they can be supported by an overhead gantry which helps.
