Abstract:

Availability of charging facilities at public places is the key prerequisite for adoption and rollout of electric vehicles (EV). This Paper examines various issues related to electric vehicle supply equipment (EVSE) or charging stations related to policies, standards, interoperability and business models for creation of an enabling EVSE ecosystem for faster rollout of EVs. EVSE or charging equipment are prerequisite for EV adoption by vehicle owners. Various countries adopted different approaches and business models for creation of EVSE ecosystem with mixed results. This Paper attempts to put together the summary of considerable work already done by various stakeholders on the above issues and look at sustainable business models for creation of EVSE ecosystem that will enable rollout of EVs on fast track. Rollout of Electric Buses are not constrained by EVSE standards as buses will be charged from the EVSEs supplied (or recommended) by the bus manufacturer which will be installed in bus depots and bus terminuses. The cost of EVSE for bus may be bundled in the cost of the bus itself. Bus Operators should ideally own and operate the EVSE for buses; and electricity to be supplied by respective DISCOMs. Grid upgrade charges if any to be considered in the annual Capex of the DISCOM – it should not be burdened on e-mobility program.
