In theory yes, but try a small game: to charge "quick enough" you need let's say 7kWp power, at 3kW you can't even balance cells, so you just end up with 80% or so maximum charge. But EVEN at 3kW: 10 workers means 30kW load, in a building there are normally MUCH more. They start all around the same timeframe. That's means a BIG grid peak load, after another peak load (when the Sun start shining). An AC grid without enough battery storage (the sole who can compensate quick enough) simply will go down unable to keep a stable frequency. The theory is that in a smart grid cars, witch happen to be rolling batteries, charge or discharge following energy needs and owner needs, the practice so far is that no such smart grid exists, inverters at maximum follow as quick as they can grid frequency witch do not allow "smart" programming at all and most chargers do not even have DC ports needed to pilot the charge/discharge bi-directional usage (since on AC in-cars inverter would demand too much signaling for a still slow response). The reality is: those who have designed the new deal have imagined to shift hyper-expensive storage costs to the people and have them mount as p.v. mount. Actually p.v. is economically interested enough so many have accept it, BEVs not much so they artificially change energy prices to "reshape the market" making BEVs interesting and as a result they create a situation that force people to switch WITHOUT the needed infra or the physical possibility.
