Government of India is looking to push for electrification of both public and private transport system. However, the mass adoption of electric vehicles is not possible without having city-wide network of charging infrastructure. On 14 December 2018, Indian government released a document to outline to guidelines and standards for charging infrastructure for electric vehicles. The key objectives of this policy document is to enable faster adoption of electric vehicles, promote affordable tariff, to build city-wide charging infrastructure, to create market for electric vehicle charging business, and to encourage preparedness of Electrical Distribution System.
The policy has outlined the following:
1. Private charging at residences / offices shall be permitted
2. Setting up of Public Charging System (PCS) shall be a de-licensed activity
3. Power Distribution Company should faciliate power connectivity to any person
4. Chain of charging stations may also obtain electricity from any generation company
The government has followed the existing current international standards like CCS, CHadeMO etc. that are prevalent and used by most vehicle manufacturers internationally. The standards for fast and slow charging stations are given below:
Every public charging station (PCS) shall be operational only after inspection and clearance as communicated by a suitable clearance certificate, by the concerned electrical inspectors/technical personnel designated specifically by the respective distribution company.
However, the public charging stations for long distance electric vehicles and / or heavy duty electric vehicles (like truck, buses etc.) shall have the following minimum requirements:
(a) At least two chargers of minimum 100 kW (with 200-1000 V) each of different specification (CCS and CHadeMO) and with single connector gun each in addition to the minimum charging requirements
(b) Appropriate Liquid Cooling Cables for high speed charging facility for onboard charging of Fluid Cooled Batteries
(c) Fast Charging Stations (FCS) for long distance EVs and/or Heavy Duty EVs may also have the option of swapping facilities for batteries for meeting the charging requriement
The guidelines also stiputated that at least one charging station should be available in a grid of 3 KM X 3 KM. Further, one Charging Station be setup at every 25 KM on both sides of highways / roads. For long range EVs and heavy duty EVs should be at least one charging station at every 100 kms. The guidelines also suggested to create and maintain a national online database of all the public charging stations by Central Electricity Authority (CEA).
