Electric vehicles (EV) are becoming ubiquitous everywhere in the world thanks in part to awareness of global warming and pollution effects. As electric cars, e-rickshaws, e-scooters become common place, so will the necessity for EVSE (Electric Vehicle Supply Equipment) or EV chargers. Since R&D is happening rampantly in many companies all around the world, standards, regulation and compliance is going for a toss.

We are implementing a standards based full-stack technology stack for connecting all stakeholders in the EV ecosystem. We have tentatively named it “Bharat EV Cloud”.

Currently, different standards exist for BEV (Battery Electric Vehicle), FCV (Fuel Cell Vehicle), EREV (Extended Range Electric Vehicle) and PHEV (Plug-in Hybrid Electric Vehicle). Charging standards vary mainly by two types:

  • slow (Level 1 and Level 2) and
  • fast chargers (AC-3Ph, DC, Superchargers)

Connector types mainly used are:

  • SAE J1772 (Type 1, 2, 3)
  • ChaDeMo
  • Combined Charging System (CCS)

Last but most important is the communication between EV, EVSE, CPO, Clearing House, eMSP and the DSO. For this, there are many interfaces, including, SAE J1772, P1901 power line communication, CHAdeMo (CAN bus protocol).

The communication protocols include:

  • OSCP
  • OpenADR
  • OCPI v0.4
  • IEEE 2030.5
  • OCPP
  • IEC 61850-90-8
  • OCHP
  • OCHPDirect
  • OCPI 2.1
  • OICP
  • eMIP
  • IEC 61851-1
  • ISO/IEC 15118

Since, the whole gamut of the protocols existing is overwhelming, standardization is required before they are adopted to the local Indian market. But, since, the vehicle manufacturers adhere to their own standards, it is necessary and essential for us to create a framework that complies and interoperates with all or most of these protocols that exist now or something that might come up in the future, including, later versions and revisions and totally new ones.

Our full-stack framework will help solve the problem of dealing with the overwhelming number of standards, protocols and various stakeholders in the ecosystem. This will be of great help to the EV industry in terms of maintaining either an exhaustive list of standards or a cloud database which could work with any of the existing or future protocol standards that might enter the EV market.


We are also working on a prototype of an EV charging station that is standards-compliant. We intend to integrate multiple standards into the same charger to create something like a Universal charging station that will comply to the Bharat EV standard specification. The proposed universal charger and the Cloud solution will have multiple connector standards according to the local market usage, multiple protocols based communication network for interoperability between

  • Charging station operators
  • eMobility providers
  • Electric supply providers
  • Payment gateways
  • Banks and
  • Other stakeholders

We are currently looking for working with Automotive OEMs, Banks and other stakeholders in the EV ecosystem for collaboration and integration. Please reach out to us to talk about our capabilities and offerings for EV Cloud solutions. Please watch out for our full solution offering @ Coming soon!!
