On Dec 14, 2018, a notification has been issued by Ministry of power signifying the standards and guidelines for charging infrastructure for electrical vehicle. Now, to enable faster adoption of electrical vehicles (EVs) by providing affordable charging infrastructure and to encourage preparedness of Electric distribution system to adopt electrical vehicle charging infrastructure, amendments are made in the relevant sections of Chapter 10 of the Model Building Bye-laws, 2016. It provides for addition of norms for charging Infrastructure provisions (for EVSEs) in Development Control Regulations and enabling provisions for installing “Charging Infrastructure” in the building premises and core urban areas of the cities.
Electric Vehicle Supply Equipment (EVSE)
An EVSE is a wall mounted box that supplies electric energy for recharging of electric vehicle batteries. Also EVSEs have a safety lock-out feature that does not allow current to flow from the device until the plug is physically inserted into the car.
Different types of EVSE
- Private Charging: Charging batteries of privately owned cars through domestic charging points. A small household outlet may charge as slowly as 1.2 kW. Billing is mostly part of home/domestic metering.
- AC “Slow” Charging: The home private chargers are generally used with 230V/15A single phase plug which can deliver a maximum of up to about 2.5KW of power. The EVSE supplies AC current to the vehicle‟s onboard charger which in turn converts the AC power to DC allowing the battery to be charged.
- Public Charging: For charging outside the home premises, electric power needs to be billed and payment needs to be collected. The power drawn by these chargers may need to be managed from time to time.
- DC “Fast” Charging: DC current is sent to the electric car’s battery directly via the charge port. Fibre Channel chargers (usually 50 KW or more) can supply 100 or more kilometers of range per hour of charging. The fast chargers would generally be used as a top-up, rather than fully charging vehicles. These are important for cab companies and corporate users who have a fleet of electric cars.
5. Public Charging Station (PCS) Infrastructure:
a) Setting up of public charging stations shall be a de-licensed activity, provided, such stations meet the technical as well as performance standards laid down by Ministry of Power (MoP) in this concern.
b) Any person seeking to setup a PCS may apply for connectivity and he shall be provided connectivity on priority by Distribution company licensee to supply power in the area.
c) Any charging station/ chain of charging stations may also obtain electricity from any generation company through open access
Guidelines and Minimum Standards for setting up Charging Infrastructure for Electric Vehicles :
- An exclusive transformer with all related substation equipment including safety appliance.
- 33/11 KV line/cables with associated equipment including as needed for line termination/metering etc.
- Appropriate civil works.
- Adequate space for Charging and entry/exit of vehicles.
- Public Charging Stations shall have, one or more electric kiosk/boards with installation of all the charger models.
- The kiosk/board may have options for installation of additional chargers if required.
- The Public Charging Station Providers are free to create Charging Hubs and to install additional number of Kiosk/Chargers in addition to the minimum number of chargers prescribed above.
- Tie up with at least one online Network Service Providers (NSPs) to enable advance remote/online booking of charging slots by EV owners. Such online information to EV owners should also include information regarding location, types and numbers of chargers installed.
- Share charging station data with appropriate Distribution company and to maintain appropriate protocols as prescribed by such Distribution company for this purpose.
Location: At the Local levels (within the urban area): At least 1 Public Charging Station is to be available within a grid of 3Km x 3Km.
At the Building premise levels (for various building types):
a) Private charging infrastructure (non-commercial use) for individuals.
b) For all commercial modes of charging EVs, at least 1PCS, as per minimum specifications laid under MoP guidelines.
c) Standalone Battery Swapping Stations may be added with the PCs.
