Electric vehicles are becoming increasingly common on Indian roads, but one question still confuses many buyers: how exactly do you charge an EV? Unlike petrol or diesel cars that rely on fuel stations, EVs can be charged at home, at workplaces, or at public charging stations. Here’s a quick guide on 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 usually deliver between 3.3 kW and 22 kW, while DC fast chargers can range from 30 kW to over 240 kW. The difference in power directly affects charging time: AC charging can take several hours, whereas DC fast charging can refill most of the battery much faster.

India currently uses several 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 by electric cars, and the Bharat AC-001 charger mainly used for two- and three-wheelers. Power output usually ranges between 3.3 kW and 22 kW.DC fast chargers are designed for quicker charging and are typically found in public charging stations or along 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 deliver between 50 kW and 350 kW, allowing many EVs to charge from 10 to 80 percent in roughly 20–60 minutes depending on battery size and vehicle compatibility.

For most EV owners in India, home charging is the primary method of charging. In fact, many automakers recommend slow charging at home as the best daily charging solution.When you buy an EV, the manufacturer typically provides a home charging unit or wall box charger. These chargers are installed in a parking area and connected to the household electricity supply. Some EVs can even 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 simply plug in the vehicle overnight and start the next day with a full battery. Charging at home is also usually cheaper because electricity tariffs for households are lower than commercial rates.

Public charging stations are designed for situations where drivers need a quicker recharge. These stations are commonly 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 depend on the operator and charger type, but fast charging usually carries a premium because of the higher equipment and electricity costs.Public chargers, on the other hand, are helpful for long-distance travel or emergency top-ups, especially on highways where fast charging can quickly add range.As EV adoption increases and more chargers are installed nationwide, the gap between electric and conventional refuelling convenience is expected to narrow significantly over the next few years.
