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.
IS 17017 is the key EV charging standard in India comprising three parts and six sections. IS-17017- Part-1 provides the basic features of all EV charging systems. An AC EVSE must adhere to this standard, and specific AC connector standards in the IS-17017-Part-2. Both AC and DC EVSE need to conform to the technical standards IS-17017-Parts 21 & 22. Additional Indian standards for AC EVSEs have been approved for light EVs and e-cars (in the form of lowcost charging points), for use in parking areas. INDIAN STANDARDS FOR DC CHARGING IS- 17017-Part-23 describes the requirements for DC charging stations, with power output of 50kW to 200kW. Beyond this, high power charging standards are required to cater to buses and other heavy vehicles. Recently, the BIS has finalized the IS-17017-Part-25, which is specifically for providing low DC power of less than 7kW for light EVs. Due to the requirement of digital communications between the DC EVSE and the EV, data communication stan...
