Charging at night at home - and that is your main option when charging infra is lacking - may even be an improvement for the nation grid's overall health and economics.
And I'll also add that night-charging can only scale up to a point, there's a point where the country would end up consuming more at night than during the day.
So it really depends on the local situation, local energy mix, local infrastructure.
Charging at a couple of kW for the night is enough for almost everybody. Very few people drive hundreds of kilometers every day and the typical EV needs 10-20kWh/100km. The grid should handle that without a problem in most places, I think. Cars are parked most of the day. If most of the parking spots offer a kW or two charging becomes a nonissue.
Solar power is new development, and it would be naturally to do it in parallel with charging infra in business districts thus providing another sink for all that daytime generated power.
