Standards for EV Chargers in India – Electric Vehicle Charging Protocol – CCS, CHAdeMO, GB/T…


Different segment of vehicles (2W, 3W, PVs, CVs) may require a different type of charging standard (& connector), however, the charging infrastructure, at least at public places, should be common to the extent possible to reduce the infra cost.

Energy companies (like IOCL, HPCL, IGL etc.) may invest in providing a charging network, especially the fast charging stations at inter-city routes like state and national highways. This could also be based on renewable electricity source.

Automotive Industry Standard – AIS 138 Part 1 (both slow charging standard and fast charging standard) is suitable for all vehicle segments as an AC charging standard and may be notified. AIS 138 Part 2 could be finalized after considering the following requirements/provisions.

For 2/3 Wheelers: A new standard unified connector is being considered which could be used both for AC and DC charging to alleviate the need for two separate slots on the vehicle for AC and DC charging respectively. IEC 62196-2 Connector (commonly known as Type-2) is one of the proposals being evaluated.

For 4-wheelers with system voltage not exceeding ~ 100 V: GB/T connector, as per the specs are given under BEVC DC-001 (Bharat EV Charger DC-001), is suitable.

For 4-wheelers with system voltage exceeding ~ 100 V deployment of “publicly available or public” DC fast chargers in the country the recharging points at such charging stations may be equipped at least with protocol and connector of the combined charging system CCS-2 (as described in the Annex-C of AIS 138 Part-2).

Further, the charging station/point installed by any private entity or individual for private purpose or for specified users, DC charging standard as described in Annex-A of AIS 138 Part-2 (i.e. Chademo) shall also be permissible

Standards for EV Chargers in India

  • ARAI had published these standards in 2016 and the DHI invited Industry response to the same
  • DHI along with NitiAyog has proposed standards for EV Chargers in India
  • The details of these standards could be found in the link[1]
Some key points on the EV Chargers
  • The charging equipment must be CE Certified
  • The charging equipment must come with a comprehensive extended on-site warranty and AMC package for 5 years from the date of commissioning and must have a design life of 10 years
  • The charging equipment before delivery, should be type tested as per AIS 138 at ARAI (Automotive Research Association of India) and IIT Madras
