India is a densely populated country and has a unique automobile market and usage pattern compares to other developed countries. In that sense, India needs an innovative approach to mainstream EV, particularly in the four-wheeler car segment. Unlike ICE (Internal combustion engine) vehicle, where people have only the option to go to a gas station to refill their fuel, In the case of EV(Electrical vehicle), electricity is ubiquitous. And it can be tapped at the street or home or the mall or public place. As EV is run by a Li-ion battery similar to the smartphone, charging can be done at home or workplace, or a public place.

To popularize the adoption of EV in the Indian context, deploying fast chargers (22-50kW) that can full charge battery within (45 minutes to three hours) on a public place and across the highway can be considered as prevalent globally. But India cannot replicate this strategy due to its unique market size and composition. Furthermore, indiscriminate deployment of fast chargers does not make economic sense as it is costly and has distribution network-related limitations. Furthermore, fast charging may reduce battery capacity over time. Keeping in mind the drawbacks of fast charging in the Indian context, cost-effective slow charging can be explored which preserves battery integrity for much longer.

The predominant usage of the car is planned travelling for daily commuting for work or occasional unplanned travelling for leisure or shopping or unplanned emergency travelling. In that sense, the dwelling time of the car, either at home or at the workplace, or public place, can be utilized to charge the car. Private cars are usually parked overnight(8 hrs) at home and parked during the daytime at the workplace(7-8 hrs), and parked at the mall, or public place sporadically or in case of an emergency travel stops in the mid-journey on the highways. So in the privately-owned car segment, the speed of charging is only needed when emergency travelling is needed. So, car owners who have enough space at their home or residential area can opt for home charging.

Home charging is relatively slow but offers convenience, cost-effectiveness, and within the owner's daily routine, and they don't need to spare extra time to recharge their car. It is possible to fully charge the battery using 3-7 kW (Type 2 AC EV Chargers)slow chargers hence home charging is preferable to fast charging in public places or highways. Compared to another mode of EV charging, providing a slow charger at residence can be a real game-changer for the Indian market. In this context, several Indian companies such as Verde Mobility has taken an initiative to provide a wide range of (Type 2 AC EV Chargers)slow chargers in 3.3kw and 7.4 KW category in the residential category.
