This growth is propelled by the low total cost of ownership (TCO) and an increasing number of models available in the market.

Types of EV charging stations in India

Electric Vehicle (EV) charging stations are categorized into three main types: Level 1, Level 2, and Level 3 (also known as DC fast charging). Each level represents a different charging speed, power output, and intended use case, from slow and convenient charging to rapid charging setups designed for quick top-ups.

Level 1 Chargers are the most basic form of EV charging. They use a standard 120-volt AC outlet, the kind found in every household. Level 1 charging is slow, generally adding about 4 to 5 miles of range per hour of charging. Due to its lower charging speed, Level 1 charging is most suitable for overnight use at home or for topping up at work during a full day.

Level 2 Chargers step up the charging capability significantly by using a 240-volt AC supply. They can add about 10 to 60 miles of range per hour of charging, depending on the vehicle and the power output of the charger. Level 2 chargers are what you typically find at public charging stations, workplaces, and homes where a faster charging option is desired. Installing a Level 2 charger at home may require electrical upgrades to support the higher voltage.‍

Level 3 Chargers, or DC fast chargers, are the quickest charging solution available. These chargers use a direct current (DC) supply to charge an EV much faster than AC chargers can. Depending on the vehicle's capacity and the charger's output, DC fast chargers can add 60 to 100 miles of range in as little as 20 minutes. These chargers are typically located along highways and in public charging stations to facilitate long-distance travel.

Public vs. Home Charging for Electric Vehicles: A Comprehensive Comparison

The distinction between public charging stations and home charging setups is primarily based on their location, accessibility, and charging speed. Public charging stations, which can include Level 2 and Level 3 chargers, are accessible to all EV drivers and are often strategically placed in locations such as shopping centers, parking lots, and along major highways to support drivers when they are away from home. These stations are crucial for the widespread adoption of EVs as they ensure drivers can find convenient, fast charging options while on the go.

Home charging setups, on the other hand, typically consist of Level 1 or Level 2 chargers. These private chargers provide the convenience of charging an EV overnight or during the day at home, ensuring the vehicle is ready to go when needed. Home charging is considered the foundation of EV charging infrastructure since it covers the daily charging needs of most drivers.

The expansion and accessibility of EV charging stations, both public and private, are critical to supporting the growing number of electric vehicles on the road. As the network of charging stations expands, drivers can enjoy greater flexibility and convenience, further encouraging the adoption of electric vehicles.

Infrastructure requirements for setting up EV charging stations in India

Establishing electric vehicle (EV) charging stations in India requires careful consideration of several key infrastructure components, location decisions, and electrical supply prerequisites, all geared toward supporting the growing adoption of EVs.
