This simple guide helps builders, project owners and businesses understand electric vehicle charging standards, different EV charging connector types, and basic charger safety. It also covers how to prepare for possible EV charger repairs.

Why EV Charging Standards Are Important

Standards are rules that help keep things safe and working properly. For EV chargers, these standards make sure:

  • Chargers work safely and don't harm users or vehicles.

  • Chargers match with different kinds of EV cars.

  • Buildings follow government rules.

  • Buildings stay modern and useful for a long time.

Without following these electric vehicle charging standards, chargers might become unsafe or outdated.

Common EV Charging Connector Types in India

Different EV cars use different types of plugs or connectors. Projects must pick connectors that work with most EV cars today and in the future.

Here are common EV charging connector types used in India:

Connector Type

Charging Type

Where It’s Used

Cars it Supports

Type 2 (AC)

Slow Charging

Homes, offices

All electric cars sold in India

CCS2 (DC)

Fast Charging

Public areas, highways

All electric cars, trucks & buses sold in India

Bharat AC001

Slow Charging

Basic, low-power setups

Older electric cars, e-scooters / bikes

Bharat DC001

Medium-Fast Charging

Public areas, some roads

Older electric cars

Projects should choose connectors like Type 2 and CCS2, as they are most common and future-friendly.

Simple Guide to EV Charger Standards & Specifications

To set up good EV charging stations, you need to know these basic things:

Specification

Meaning

Why It Matters

Power (kW)

Speed of charging

Helps you decide how fast cars can charge

Voltage & Current

Electric power details

Matches building electrical infrastructure to avoid problems

Ingress Protection Rating (IP)

Weather & dust resistance

Protects chargers installed outdoors

Impact Protection Rating (IK)

Toughness

Keeps chargers safe in busy places

Mounting Type

How it’s installed (wall/pedestal)

Fits well with your parking design

Communication

Smart control features

Helps users manage charging easily

Certification (BIS, ARAI)

Safety approval

Makes sure chargers follow safety rules

Important Safety Features Every EV Charger Should Have

Safety always comes first. Good chargers should have these safety features:

  • Over Current Protection – Stops damage from too much electricity.

  • Over / Under Voltage Protection - Stops charging if input voltage is outside the safe range.

  • Surge Protection – Protects charger & EV from sudden electrical spikes.

  • Short Circuit Protection – Safely shuts off power during problems with the electrical supply or switchgear.

  • Ground Fault Protection – Stops charging if electricity leaks or if ground wire is disconnected.

  • Overtemperature Protection – Shuts down if charger or the connecter get too hot.

  • Communication Fault Detection - Takes required action if communication with EV fails.

  • Internal Checks - Takes required action if the charger detects any internal fault with a component, such as relay weld or isolation failure.

  • Plug-Out Protection – Stops charging when plug is removed.

Knowing these safety points also helps in planning better EV charger repairs if problems ever occur.

Important Indian EV Charger Standards to Follow

Builders must follow these main electric vehicle charging standards in India:

  • Bharat AC001/DC001 – India’s early basic charger standards.

  • IS 17017 (Parts 1–24) – India's main EV charger standard (like international IEC standards).

  • ARAI & BIS Certification – Official approval needed for chargers in India.

  • OCPP Protocol – Smart charger communication to manage charging online.

Key Points to Remember

  • Follow government-approved EV charger standards to keep things safe and legal.

  • Pick connectors that most EV cars can use now and in the future.

  • Make safety your top priority when installing chargers.
