Commercialisation of Isro’s technology could save 10-15 per cent of the cost of e-vehicles. Some experts are of the view that the electric vehicle technology is still in the development stage and the cost is substantially higher. Besides, the ecosystem for e-vehicles is not yet ready. “Charging stations are not in place, the cost of the battery itself is high. There are affordability and durability issues,” an expert said.
A challenge is customer scepticism about the workability of electric vehicles. Officials said it was important to weigh the economic consequences of the deployment of electric vehicles on a large scale. Concerns include the difference in the cost of an ordinary automobile and an e-vehicle. The cost of an ordinary electric bus is approximately Rs 1.5 crore if procurement volumes are assured as against the Rs 20-50 lakh cost of diesel buses.
