Keep in mind no where in the world EV chargers are installed or operated by government.
Charging companies along with EV makers are the ones mostly responsible. Government only can give incentives but with limited EV'S and also being expensive, I dont know if it would be easy for someone to deploy a country wide network or at least on motorways and I m not talking about the typical 55kwh chargers currently you see few in Lahore or Islamabad. I am talking about fast DC chargers with 100kwh and over capacity, along with it maintenance and 24/7 input from grid.
Last I know many times the service areas on motorway and pumping stations in summer are running on the generators because of shortfall. EV will not work that way.. people even in Europe and US where there are extensive charging network are skeptical buying EV because of range anxiety.
