India's transition to electric mobility depends heavily on a reliable charging network. While vehicle sales are growing, the supporting infrastructure faces multiple hurdles that affect both consumers and automakers. This article examines the current state of EV charging infrastructure in India, the key challenges, and what needs to be done to build a robust ecosystem.
Current status of charging infrastructure
As of early 2025, India has over 26,000 public charging stations, a significant increase from around 5,000 in FY22. However, this still translates to only one public charger for every 235 electric vehicles on the road. The distribution remains heavily skewed toward urban centers, leaving highways and rural areas underserved. Most public chargers are slow AC units below 22 kW, while fast DC chargers above 50 kW are limited. The three-wheeler segment dominates EV sales at 66 percent, followed by two-wheelers at 30 percent, while four-wheelers account for only 4 percent of the EV fleet. This vehicle mix influences the type of charging infrastructure needed.
Grid integration and power supply challenges
Integrating EV charging loads into the distribution grid is a major technical challenge. Most Indian distribution networks were designed for conventional domestic loads, not the concentrated, high-power demand from EV chargers. Studies by IIT Bombay and distribution utilities like BSES and CESC show that uncontrolled charging can cause transformer overloading, voltage fluctuations, and increased line losses. In Delhi, case studies revealed that high EV penetration increased transformer overloading instances by 35 percent. Smart charging and battery energy storage systems can mitigate these impacts, but they require advanced metering, communication infrastructure, and grid observability that are still lacking in many areas. The National Smart Grid Mission aims to replace 25 crore conventional meters with smart meters, but progress has been slow with only about 15 lakh installed as of 2021.
Standards and interoperability issues
India has developed multiple charging standards including Bharat AC-001, Bharat DC-001, IS 17017 series, and AIS 138. However, most two-wheelers and three-wheelers use proprietary connectors and charge via standard 15A sockets, making them incompatible with public chargers. Four-wheelers from Tata, Hyundai, and MG use CCS2 connectors, while the Bharat DC-001 standard supports only sub-100V systems that are becoming obsolete. The lack of a unified connector standard for light electric vehicles creates confusion for charge point operators and users. The recently released IS 17017 Part 22 for LEV AC charging recommends industrial IEC 60309 sockets, which require adapters for most existing vehicles. Interoperability and e-roaming between different charge point operators' networks remain limited due to absent communication standards between operators and distribution utilities.
Policy and regulatory gaps
The FAME II scheme allocated 10 percent of its INR 10,000 crore budget for charging infrastructure, sanctioning 2,877 stations across 62 cities. However, allocation was not aligned with actual EV demand. For example, Delhi with around 3,000 four-wheel EVs received only 72 stations under FAME II, while Chandigarh with just 100 four-wheel EVs got 70 stations. Most states have notified EV policies, but few address home and workplace charging, grid upgrades, or provide incentives for battery swapping. Building bye-law amendments from 2019 mandating 20 percent EV-ready parking in new constructions have seen poor adoption by state governments. There is no single-window clearance for charging station approvals, and land availability in suitable locations remains a constraint. The Ministry of Power's revised 2022 guidelines delicensed public charging and capped service charges, but implementation varies across states.
Financial viability and business models
Setting up fast-charging stations requires significant capital for equipment, transformers, civil works, and grid upgrades. A 50 kW DC charger costs around INR 11 lakh, while a 150 kW unit costs INR 15 lakh. Distribution transformer upgrades add further costs. Charge point operators face low utilization rates in the early market, with industry averages around 5-6 percent, making revenue recovery difficult. High electricity tariffs and demand charges in many states worsen the economics. The Ministry of Power has capped public charging tariffs at the average cost of supply until March 2025, but many states set EV tariffs higher than residential rates. Private investment remains limited without viable business models, and most infrastructure deployment has been led by public sector entities.
The chicken-and-egg problem
Automakers hesitate to launch new EV models without charging infrastructure, while charge point operators wait for higher EV penetration to ensure utilization. This deadlock particularly affects the four-wheeler segment where battery capacities of 30-45 kWh require fast charging for practical long-distance travel. Consumer surveys in Delhi show that long charging times and lack of private charging access are top barriers to EV adoption. Fleet operators and ride-hailing services are the primary users of existing fast chargers, but they represent a small fraction of total vehicle sales. Without a critical mass of EVs that can use public fast chargers, infrastructure investments remain risky.
State-level initiatives showing progress
Some states have demonstrated effective approaches. Delhi offers 100 percent subsidy for private charging equipment up to INR 6,000 per point, mandates EV-ready parking in new buildings, and targets a charger within 3 km anywhere in the city. Karnataka provides capital subsidies for fast chargers and battery swapping stations, and has installed chargers at metro and bus depots. Maharashtra's 2021 policy offers 60 percent subsidy for slow public chargers and 50 percent for fast chargers, with city-wise targets. Tamil Nadu leverages its renewable energy capacity to offer preferential green power for charging. Goa provides concessional land and capital subsidies for solar-powered stations. These models show how state-level action can complement national schemes.
The role of battery swapping
Battery swapping addresses range anxiety and long charging times for two and three-wheelers. The government allowed sale of EVs without batteries in 2020 to reduce upfront costs. Several operators like Sun Mobility, Lithion Power, and ChargeUp are building swapping networks. However, standardization of battery packs across OEMs remains a challenge. GST on standalone batteries at 18 percent versus 5 percent on complete EVs creates a tax disincentive. FAME II subsidies are linked to battery size, complicating incentives for battery-less vehicles. A draft battery swapping policy released in April 2022 aims to address these issues.
Vehicle-to-grid and renewable integration
EVs can support grid stability through vehicle-to-grid (V2G) services like frequency regulation and peak shaving. Pilot projects in Bengaluru and West Bengal have demonstrated solar-powered charging with battery storage, reducing grid dependence and emissions. However, no EV models with bidirectional charging are currently sold in India. Regulatory frameworks for aggregating EVs as virtual power plants are absent. The Central Electricity Regulatory Commission's 2021 draft ancillary services regulations could enable EV participation, but implementation is pending. Time-of-day tariffs for EV charging exist in only a few states like Delhi, Maharashtra, and Kerala.
Workforce and consumer awareness gaps
India lacks adequate trained personnel for EV charger installation, maintenance, and grid integration. The Automotive Research Association of India and various skill development agencies offer training programs, but coverage is limited. Consumer awareness about charging options, costs, and benefits remains low. Many potential buyers are unaware of home charging feasibility or government incentives. Digital platforms for real-time charger location, availability, and payment are still evolving, with the first unified app EV Plugs launched only in 2021.
The challenges facing EV charging infrastructure in India are interconnected and require coordinated action across policy, regulation, technology, and finance. Grid upgrades, standardized connectors, aligned subsidies, viable business models, and consumer awareness must advance together. State governments play a crucial role in land allocation, tariff design, and building bye-law enforcement. The next few years will determine whether India can build a charging network that keeps pace with its EV ambitions.
