Electric vehicle on-board charger EMC Requirements

Electric vehicle on-board charger EMC requirements for conductive

connection to an AC/DC supply:

This is a part of IEC gives requirements for conductive connection of an electrical vehicle (EV) to an AC or DC supply. It applies only to onboard charging units either tested on the complete vehicle or tested on the entire charging system component level (ESA – electronic sub assembly)

Specific safety requirements that apply to equipment on the vehicle during charging are treated in separate documents as indicated in the corresponding clause of this document. Electric vehicle (EV) includes pure electric vehicles as well as plug-in hybrid electric vehicles with additional combustion engine.

REESS:

Rechargeable energy storage system that provides electric energy for electric propulsion of the vehicle

On-board EV charging system:

All equipment in the charge power suppl y chain inside the vehicle.

Electrical /electronic sub-assembly ESA:

Electrical and/or electronic device or set(s) of devices intended to be part of a vehicle, together with an y associated electrical connections and wiring, which performs one or more specialized functions.

Low voltage (LV):

Operating DC voltage below 60V. (Nominal voltages of 12V, 24V,48V)

Low voltage harness with operating voltages below 60V.

High voltage (HV)

Operating voltages of 60V to 1000V, HV+ an d HV- are abbreviations for the positive and negative terminal line, respectively.

Function performance criteria:

Performance criterion A: The vehicle shall not be set in motion. The charging function shall continue to operate as intended during and after the test. No degradation of performance or loss of function is allowed.

Performance criterion B: The vehicle shall not be set in motion. The charging function shall continue to operate as intended after the test. During the test temporary loss of charging function is allowed provided the charging function is restored automatically without user interaction.

Performance criterion C: The vehicle shall not be set in motion. Temporary loss of function is allowed provided the function can be restored by simple operations of the controls and without the use of tools, by the user of the equipment or operator from remote position.


Electrifying India: Electric Vehicle Charging Station

Currently, Indian roads are dominated by conventional vehicles and have approximately 0.4 million electric two-wheelers and a few thousand electric cars only. In this regard, Ministry of Power has issued “Guidelines and Standards- Electric vehicle charging station” mentioning the roles and responsibilities of various stakeholders at Central & State level, for expediting the development of public Electric vehicle charging station in India.

As more and more businesses and homeowners are steadily turning to electric vehicles, the charging stations are getting more and more popular across the Country.

The Government of India felt the need for a permanent agency (Consultant) to expedite the publication of standards and development of test facilities in parallel when the work of preparation of standards is going on, as the development of improved safety critical parts can be undertaken only after the Verification of the standard and commissioning of test facilities.

Indian Government have undertaken multiple initiatives to promote manufacturing and adoption of electric vehicles in India. With support of the Government, electic vehicle charger have started penetrating in the Indian automobile Market. However, availability of adequate Charging Infrastructure is one of the key requirements for accelerated adoption of electric vehicles in India. It is proposed to encourage this by laying down an enabling framework.

Objective:

  • To enable faster adoption of electric vehicles in India by ensuring safe, reliable, accessible and affordable Charging Infrastructure and eco-system.
  • To promote affordable tariff chargeable from EV owners and Charge Stations Operators/Owners
  • To generate employment/income opportunities for small entrepreneurs
  • To proactively support creation of EV Charging Infrastructure in the initial phase and eventually create market for EV Charging business
  • To encourage preparedness of Electrical Distribution System to adopt electric charging station.
