Electric vehicles are becoming increasingly common on Indian roads, but one question still baffles many buyers: How do you charge an EV? Unlike petrol or diesel cars that rely on fuel stations, EVs can be charged at home, workplaces, or public charging stations. Here’s a quick guide to home vs public charging.
How EV Charging Works
EV chargers are broadly classified into AC chargers (slow or normal) and DC fast chargers. AC chargers typically deliver between 3.3 kW and 22 kW, while DC fast chargers can range from 30 kW to 240 kW. The difference in power directly affects charging time: AC charging can take several hours, while DC fast charging can refill most batteries much faster.
Types of EV Chargers Used in India
India currently uses multiple charging standards to support different types of vehicles. AC chargers are the most common type and are usually installed in homes, offices and residential complexes. These include the Type-2 AC charger, which is widely used in electric cars, and the Bharat AC-001 charger, mainly used for two- and three-wheelers. The power output is usually between 3.3 kW and 22 kW.DC fast chargers are designed for fast charging and are usually found at public charging stations or on highways. These include standards such as CCS2, which is currently the dominant fast charging system for electric cars in India. High-power DC chargers can provide between 50 kW and 350 kW, allowing many EVs to charge from 10 to 80 percent in about 20-60 minutes, depending on battery size and vehicle compatibility.
Home charging: The most common option
For most EV owners in India, home charging is the primary method of charging. In fact, many vehicle manufacturers recommend slow charging at home as the best daily charging solution.When you buy an EV, the manufacturer usually provides a home charging unit or wall box charger. These chargers are installed in the parking area and connected to the household power supply. Some EVs can also charge through a standard 15-amp plug socket, although a dedicated wall charger is usually faster and safer.The biggest advantage of home charging is convenience. Owners bus the vehicle overnight and start the next day with a full battery. Charging at home is also generally cheaper because residential electricity rates are lower than commercial rates.
Public charging: Useful for travel and quick top-ups.
Public charging stations are designed for situations where drivers need to charge quickly. These stations are usually located at shopping malls, office parking areas, petrol pumps, highways and dedicated EV charging hubs. However, public charging often costs more than charging at home. Charging rates vary depending on the operator and type of charger, but faster charging usually carries a premium due to higher equipment and power costs.On the other hand, public chargers are helpful for long-distance trips or emergency top-ups, especially on highways where fast charging can increase range quickly.As EV adoption increases and more chargers are installed across the country, the gap between electric and traditional refueling facilities is expected to narrow significantly over the next few years.
