Types of EV Chargers Explained: How They Work & Which One You Need

Types of EV Chargers Explained

There are three main types of EV chargers Level 1 (AC, home socket), Level 2 (AC, faster wall box), and Level 3/DC fast charging (public, rapid). EV charging works by feeding electricity from a power source through a charger into your car’s battery, and since batteries store direct current (DC) but most power sources supply alternating current (AC), your vehicle’s onboard charger (or the DC charger itself) handles that conversion. Which charger is “valid” for your EV comes down to one thing: connector compatibility, not charger speed India’s passenger EVs mostly use Type 2 (AC) and CCS2 (DC) connectors, though CHAdeMO, GB/T, and the government-backed Bharat AC001/DC001 standards also exist.

This guide breaks down exactly how charging works, the different charger levels, every connector type you’ll encounter in India, and most importantly a compatibility table so you can check which charger actually fits your car.

How EV Charging Actually Works

What happens when you plug in

When you connect your EV to a charger, electricity flows from the power source a wall socket, a home wall box, or a public charging station through a cable into your car’s battery. This equipment is technically called EVSE (Electric Vehicle Supply Equipment), and it doesn’t just “push” power blindly: a communication system between the charger and your car’s computer manages voltage, current, and safety limits throughout the session.

AC vs. DC why your car has an onboard charger

Here’s the part that confuses most new EV owners: your battery can only store direct current (DC), but most home and public charging points supply alternating current (AC). To bridge that gap, every EV has an onboard charger (OBC) a component that converts incoming AC into DC before it reaches the battery.

DC fast chargers skip this step entirely. They convert AC to DC inside the charging station itself and feed DC directly to your battery, bypassing your car’s onboard charger which is exactly why DC fast charging is so much quicker.

What determines charging speed

Three things decide how fast your car charges:

  1. The charger’s power rating (measured in kW)
  2. Your car’s onboard charger capacity (a car with a 7.2 kW OBC won’t charge faster than that, even on a 22 kW AC charger)
  3. Your battery’s size and current charge level (charging slows down as the battery approaches 100%, which is why most guidance recommends charging to 80% for daily use)

Types of EV Chargers by Level

Level 1: The starting point

Most new EV owners in India begin here charging through a standard 15A household socket using the portable cable that comes with the car. It’s the slowest option, but it needs no installation and works anywhere you have a normal power outlet.

Level 2: The everyday upgrade

This is what people usually mean by “installing a home EV charger.” A wallbox unit delivers significantly more power than a wall socket, cutting charging time dramatically. It’s the standard choice for home charging, workplace parking, and increasingly, housing societies allocating charging slots to residents.

Level 3 / DC Fast Charging: For when time matters

Found at highway charging corridors and public fast-charging stations, DC fast chargers can take a battery from empty to 80% in well under an hour. They’re designed for intercity travel and quick top-ups rather than daily overnight charging and because they bypass your car’s onboard charger, they need to be a public station rather than something installed at home.

EV Charger Connector Types in India

Connector type determines whether a charger can physically plug into your car separate from charging speed or level.

Type 2 (AC)

The default AC connector for passenger EVs in India. Nearly every EV launched after 2021 supports Type 2 for home, workplace, and public AC charging.

CCS2 (DC)

CCS2 (Combined Charging System Combo 2) charger plug

The dominant DC fast-charging standard in India, used by most major EV brands including Tata, Mahindra, Hyundai, Kia, MG, and BYD. If you’re using a public DC fast charger, this is the connector you’ll most often encounter.

CHAdeMO (DC)

CHAdeMO

An older Japanese DC fast-charging standard, mainly associated with earlier Nissan models. Its presence in India is now limited as CCS2 has become the dominant standard.

GB/T (AC/DC)

GB/T Charger socket

Widely used in China, GB/T shows up on a smaller number of EVs in the Indian market with Chinese origins or components.

Bharat AC001 / Bharat DC001

India’s own government-promoted charging standards, developed to reduce dependence on international connector standards and support indigenous EV infrastructure. Bharat AC001 handles AC charging, while Bharat DC001 covers DC fast charging both are increasingly specified in government and fleet charging deployments, even though Type 2 and CCS2 remain more common for private passenger vehicles today.

Which Charger Type Is Valid for Your EV?

     
EV Brand/Model AC Connector DC Fast Charging Connector
Tata Nexon EV / Punch EV / Tiago EV Type 2 CCS2
Mahindra XUV400 Type 2 CCS2
Hyundai Kona Electric / Ioniq 5 Type 2 CCS2
MG ZS EV / Comet EV Type 2 CCS2
Kia EV6 Type 2 CCS2
BYD Atto 3 / Seal Type 2 CCS2
Electric two-wheelers (Ather, Ola, TVS) Proprietary/Type 2 variants Typically no DC fast charging check manufacturer specs

Note: CCS2 has become the near-universal DC standard for Indian passenger EVs, but always confirm your specific model’s connector in the owner’s manual before relying on a public fast charger especially for two-wheelers and older imported models, which sometimes use different standards.

How to Find a Compatible Charging Station

Once you know your connector type, the next step is finding a station that actually supports it not every public charger offers every connector type, and showing up to a CHAdeMO-only station with a CCS2 car wastes time you don’t have.

Frequently Asked Questions

How do I know which charger type my EV uses?

Check your car’s owner’s manual or the charging port itself most Indian passenger EVs use Type 2 for AC charging and CCS2 for DC fast charging, but always confirm your specific model.

 No CCS2 combines the Type 2 AC pins with two additional DC pins, but it requires a car built to accept CCS2 DC charging. A pure Type 2 AC-only vehicle cannot use a CCS2 DC fast charger.

No, they are different connector standards. Bharat AC001 is India’s own government-promoted AC connector, developed separately from the internationally used Type 2 standard, though both serve the same AC charging purpose.

 It depends on the charger level: roughly 8–12 hours on Level 1, 4–8 hours on Level 2, and 20–60 minutes to reach 80% on a DC fast charger actual time also depends on your battery size and current charge level.

Occasional DC fast charging is generally fine for modern EV batteries, which include thermal management and battery management systems (BMS) to regulate the process safely. However, most manufacturers recommend using Level 1 or Level 2 charging for daily use and reserving DC fast charging for longer trips, since frequent fast charging can contribute to faster battery degradation over time.
