The grid connection isn't that high, because the average person (in the US) drives 50km a day. At 200Wh/km efficiency (this is a generous estimate) that's 10kW

The grid connection isn't that high, because the average person (in the US) drives 50km a day. At 200Wh/km efficiency (this is a generous estimate) that's 10kWh/day per driver. Assuming charging of all these cars is concentrated across 8 hours (10pm to 6am), 2kW per driver is more than sufficient. What's needed is EVSEs (charging connectors) that intelligently communicate to share the grid connection (this already exists).
