Overview of electromobility standards
The Government of India has made climate change commitments at the COP21 Summit held at Paris to reduce emission intensity by 33- 35% by 2030 from 2005 levels.Electric mobility presents a viable alternative in addressing these challenges.Electric mobility will also contribute to balancing energy demand, energy storage and environmental sustainability.
What is electromobility?
It is also called e-mobility.Electro mobility represents the concept of using electric powertrain technologies, in-vehicle information, and communication technologies and connected infrastructures to enable the electric propulsion of vehicles and fleets.
In this blog post, we’ve put together a list of the EV charging industry standards and protocols which deliver the flexibility that is needed for the entire electric vehicle market
What is the need of standards
Several standards are published at the global level by the International Electrotechnical Commission (IEC) and the International Organization for Standardization (ISO) and transposed in supra-national and national versions.
Safe operation and reliability of batteries, controls, plug connectors, switches, and wires need to be assured for accident avoidance.
1 Accessories:
IEC 62196
This part of IEC 62196 is applicable to plugs, socket-outlets, connectors, inlets and cable assemblies for electric vehicles, intended for use in conductive charging systems which incorporate control means, with a rated operating voltage not exceeding:
Some charging can be achieved by direct connection from an electric vehicle to common mains socket outlets. Some modes of charging require a dedicated supply and charging equipment incorporating control and communication circuits. This standard covers the mechanical, electrical and performance requirements for dedicated plugs, socket outlets, vehicle connectors and vehicle inlets for interfacing between such dedicated charging equipment and the electric vehicle.
- Part 1: General requirements
- Part 2: Dimensional compatibility and interchangeability requirements for a.c. pin and contact-tube accessories
- Part 3: Dimensional compatibility and interchangeability requirements for d.c. and a.c./d.c. pin and contact-tube vehicle couplers

2.Communications
ISO 15118-1,2,3
The official nomenclature for ISO 15118 is “Road Vehicles – Vehicle to grid communication interface.”ISO 15118 is one of the most important and future-proof standards available today.ISO 15118 enables the integration of EVs into the smart grid .A smart grid is an electrical grid that interconnects energy producers, consumers, and grid components like transformers by means of information and communication technology.
ISO 15118 will significantly affect the future of global electric vehicle charging because of these three key factors:
Convenience to the customer that comes with Plug & Charge
The enhanced data security that comes with the cryptographic mechanisms defined in ISO 15118
Grid-friendly smart charging
ISO 15118’s Plug & Charge feature also enables the EV to automatically identify itself to the charging station and get authorised access to the energy it needs to recharge its battery. This is all based on the digital certificates and public-key infrastructures made available through the Plug & Charge feature.
ISO 15118-1,2,3
Road vehicles - Vehicle to grid communication interface
- Part 1: General information and use-case definition
- Part 2: Network and application protocol requirements
- Part 3: Physical and data link layer requirements

IEC 61850
IEC 61850 is an international standard defining communication protocols for intelligent electronic devices at electrical substations.
IEC 61851-24 Electric vehicle conductive charging system - Part 24: Digital communication between a d.c. EV charging station and an electric vehicle for control of DC charging
3. Charging topology
IEC 61439-7
IEC 61439-7:2022 defines the specific requirements for assemblies for the following applications: marinas, camping sites, market squares and electric vehicle charging stations as follows:
- assemblies for which the rated voltage does not exceed 1 000 V AC or 1 500 V DC;
- assemblies intended for use in connection with the generation, transmission, distribution and conversion of electric energy, and for the control of electric energy consuming equipment;
- assemblies operated by ordinary persons (e.g. to plug and unplug of electrical equipment);
- assemblies intended to be installed and used in market squares, marinas, camping sites and other similar sites accessible to the public including temporary installations;
- assemblies intended for charging stations for electric vehicles (AEVCS) for Mode 3 and Mode 4. They are designed to integrate the functionality and additional requirements for electric vehicle conductive charging systems according to IEC 61851-1:2017.

4. Safety / security
EVs require rigorous safety testing. The same safety standards required for conventional vehicles also apply to EVs. The safety standard covers a wide range of specific details pertaining to information management, privacy, installation, occupant injury prevention, and insulation against electric shock. The safety issues of EVs are largely covered by the international standard ISO 6469. This standard has three parts:
On-board electrical energy storage, i.e., the battery
Functional safety means protection against failures
Protection of persons against electrical hazards
