I don't know why you prefixed with "Yet" when I clearly spelt out the trade-offs and contrasts in distribution between H2 and electricity.
The Mirai goes from empty to full in 5 minutes or less - which compares very well with fossil-fuel burners. Now that every OEM has abandoned battery-swapping, how fast can EV batteries be safely charged with the said 3 phases? How long were the charging time when the Mirai was debuted? That was the trade-off Toyota was hoping to fall on the good side of, nevermind the Japanese government bet on hydrogen and whatever incentives are available for Toyota.
>with "Yet" when I clearly spelt out the trade-offs
It was with regard that 800V was the driving factor, it'd be possible to have 'fast' charging earlier with existing infrastructure, even home.
>be safely charged with the said 3 phases?
The limiting factor for charging would be charging current in lots of cases. Getting 60% of 75kWh battery, it's 45kWh to charge in 20mins, the output should be ~150kW (90% efficiency) or 325A (on 400v), 4x 12-15mm wires.
Note about 'home' charging - three phase 32A is widely available domestically or around 6-8h to fully charge

North America has 3 phase power for any necessary purpose (factory, DC rapid charging station etc). It's 480V/227V.
