I even had my work as an example - we have 8 chargers, 30a level 2. That’s lower than many of us get at home
…… but that’s the point where a better goal should be to just make up for energy used by the commute. The reality is most of us move cars at lunch time. 8 fairly low end chargers is sufficient to top off 16 cars in a standard workday.
That factory didn’t need bigger chargers, and could easily halve that if you don’t expect people to share
