CHAdeMO is Betamax all over again. It's the best standard because it supports bidirectional power flow, which theoretically allows EVs to support the grid during demand spikes.

But if course CHAdeMO is dying. NACS is second best because it's less bulky than CCS, and NACS is winning in the US so the situation is less bad than it might have been.

My electric truck supports bidirectional power flow through NACS. Currently only usable with Tesla-specific vehicle and hardware, but the connector itself does support it. It was very useful during a few multi-day power outages.
