There are different types of EV chargers based on the power or voltage level they operate at and the time required for charging.

The slowest chargers are level 1 chargers which operate on normal 120V household current. These can fully charge an EV battery in 20-30 hours. Level 2 chargers operate at higher voltage between 208-240V and can charge an EV battery in 4-8 hours. These are commonly installed in homes and workplaces for overnight or opportunistic charging.

Level 3 or DC fast chargers have the highest power level and can charge an EV battery to 80% within 30-45 minutes. They operate at higher voltages between 400-600V and require special cables and connectors to deliver high power levels quickly. Fast chargers are suitable for public charging along highways to enable long distance travel in EVs.

Charging Infrastructure Development in India

Driven by pollution concerns and India's commitment to reduce carbon emissions, EV adoption is steadily growing in the country. However, limited availability of public charging stations continues to be a key hurdle hampering wider EV adoption.

As per estimates, India requires about 4,00,000 public EV charging stations by 2026 to support the anticipated EV fleet. Currently there are only around 2,800 public chargers across India.

To accelerate EV infrastructure development, the government has launched the Faster Adoption and Manufacturing of Hybrid and Electric Vehicles (FAME) scheme. Several startups and major oil companies are also setting up public charging networks across major cities and highways.

Some key initiatives include Tata Power setting up 100 DC fast chargers across major highways. IOC's plans to set up 7,000 EV charging stations across the country in the next 3 years. BPCL and Fortum Charge & Drive are also progressively expanding their public charging footprint.

State governments are proactively working to develop state-specific EV policies with focus on charging infrastructure. Many have also notified changes in rules and regulations to enable setting up of public Electric Vehicle Charger stations.

Challenges of Developing Public Charging Stations

While initiatives are underway, developing public charging infrastructure in India continues to face unique operational and economic challenges:

- Space constraints in populated cities makes it difficult to install chargers without disrupting traffic or encroaching on scarce public space. This leads to higher installation costs.

- Fluctuating power supply and frequent outages in many parts of the country affect reliable operation of chargers. This necessitates installation of expensive backup energy solutions like batteries.

- Low EV penetration currently results in under-utilization of charging assets, affecting the economics for investors. Charging operators have to subsidize costs initially to achieve scale.

- Absence of standards and protocols for identification, authentication, payment and roaming across different charging networks creates confusion for users.

- Right of Way (RoW) approvals from different government agencies and integration with multiple utility systems leads to delayed roll-out of charging projects.

- Ensuring 24x7 security and maintenance of equipment installed in public places is another operational challenge faced by charging companies.

Innovation and Partnerships - The Way Ahead

As India pushes to expedite the green mobility transition, adoption of innovative and collaborative approach will be critical to deal with infrastructure challenges.

Focus is needed on standardized ultra-fast charging technologies, renewable energy integration and localized energy storage solutions. Smaller modular charging units with flexible installation will help optimize city infra utilization.

Partnerships between private and public entities leveraging their respective capabilities hold promise. State agencies can provide land parcels while private firms handle technical and operational aspects.

Charging operators also need open platforms to facilitate seamless roaming and payments across networks. Over-the-air system upgrades will increase reliability of equipment operation.

With concerted efforts across all stakeholders, India's charging infrastructure capabilities can match global benchmarks to accelerate e-mobility transition and meet its environmental responsibilities. The coming years will be transformative as partnerships and innovations help build a robust Electric Vehicle Charger ecosystem.
