Accessible, reliable, and affordable electricity is a prerequisite for adequate charging infrastructure provision. For a rapidly scalable EV charging network, the ubiquitous low-tension (LT) electricity distribution infrastructure should be leveraged wherever feasible to provide electricity connections for EV charging. A distributed approach to charging infrastructure, comprising primarily of normal-power charging points, ensures that most charging points can be connected to the LT electricity network. This chapter explores the regulatory and governance provisions that impact EV charging connections, and lays out three methods for arranging electricity supply to private or public charging facilities.
Site selection for public charging infrastructure should optimize accessibility, visibility, and ease of navigation for charging facilities. For a given charging demand in an area, a distributed planning approach may be used to select multiple charging sites, with varying configurations of the number of chargers and power levels as required. This can reduce the space and electricity load requirements at each site, and enable more efficient network implementation. Sites for public charging may include on-street parking spots, off-street public parking, transit station parking areas, or any other location with adequate space and access for all EV owners. Ownership of sites may vary and may require multiple agreements for reserved charging use.
