Slow charger: A game-changer for the adoption of EV in India

As a signatory of the Paris agreement, India has taken many significant steps to decarbonise its energy system. One of the recommendations of the Paris agreement is to use electricity as fuel to run the transport sector. Responding to this recommendation, India is embarking aggressively to transform its transport sector. Today, India is the second-largest populated county with a population of 1.2 billion people and will reach 1.5 billion by 2030. Thanks to rapid urbanization, 40% of the urban population will settle in metropolitan areas, putting massive stress on public transport. In this context, Electric mobility can be boon for India as it will bring down reliance on hydrocarbon from transportation and facilitate the integration of renewables to the grid and fight air pollution.

India has the potential to lead the world in EV adoption, but lack of charging infrastructure and longer charging time are two major bottlenecks for the mass adoption of EV. To address these bottlenecks, India needs to apply a unique strategy for deploying charging infrastructure to mainstream the EV in the transport sector. Compared to other developed nations, India has a unique automobile market both in passenger vehicles and freight vehicle segments. Globally, four-wheelers are the dominant mode for transportation, but in India, two-wheelers and three-wheelers are the dominant modes of transportation. Only 12% of vehicles plying on the Indian roads are mass cars, including shared mobility cars. In contrast, 2% of vehicles are in the luxury segment. Due to this unique market condition in India, EV policy regarding charging cannot be one fit for all the segments. But the charging infrastructure must be ubiquitous and must address a specific need of each segment in terms of convenience and must be aligned into the user’s daily routine, keeping in mind parking time, parking place, and total km driving.

Types of charger

Chargers are defined based on the time duration taken to charge a vehicle’s battery fully. If the charging takes four to eight hours, it is referred to as a slow charger. If the charging takes one hour, it is referred to as a fast charger, and if the charging time is less than 30 minutes, it is usually referred to as the super-fast charger. Charging at home is more predictable while charging at a public place is more ad-hoc and for shorter periods. Charging at home or charging at the workplace or charging at a public place, or charging on the highway. In most cases, private car use for the planned journey, whether to market or workplace or leisure in that sense charging at home or public place is preferred. In case of unplanned or emergency long journey charging on highway come to picture. Due to grid limitations in the Indian context, DC fast charging can’t be installed at home. Furthermore, India is a densely populated country and there can’t be the indiscriminate installation of EV chargers at residential areas too. So keeping in mind, grid capacity both slow chargers should be installed at home and fast chargers should be installed at highways. Many Indian companies have taken the initiative to provide AC Chargers in India. Verdemobility, a division of System level solutions, is one of the pioneering companies to serve these niches in (Bharat AC 001) 3.3 kV and type2 AC EV Chargers in 7.4- 22 kV categories.
