EV Charging in Kolkata

Public charging directories list around 57 public charging points across Kolkata as of 2026. That is smaller than Delhi NCR or Bengaluru, but it is growing, and West Bengal policy targets a vehicle to public charge point ratio of 8 alongside rapid chargers roughly every 25 km on inter-city green routes. Because a listed station is not always working, live availability in an app is a better guide than a directory count.

The densest cluster is Alipore and the southern belt, with Tata Power and IOCL sites on Belvedere Road, Judges Court Road and Alipore Road. New Town and Rajarhat have newer CESL points including Eco Park. IOCL fuel station forecourts across the city are useful for quick DC top-ups, and rapid chargers are being added along inter-city routes such as Kolkata to Asansol and Kolkata to Digha. Check live status before setting out.

West Bengal offers a purchase subsidy for four-wheelers of roughly ₹10,000 per kWh of battery capacity, capped at ₹1.5 lakh per vehicle, generally applied at the point of purchase by authorised dealers. Battery electric vehicles also receive road tax exemption, registration fee waivers, SGST reimbursement and parking fee exemptions. The original policy was notified in 2021 with a five-year term, so confirm the current status and any successor policy with your dealer before purchase.

Tata Power, IOCL and the government-backed CESL operate the largest shares of Kolkata’s public charging, alongside dealer networks such as MG and Hyundai. Because the network is split across operators, drivers often need a different app and wallet for each. EV roaming is designed to remove that, letting one account and one payment method work across networks.

Kolkata carries a wide mix. CCS2 is the DC fast charging standard used by most electric cars sold in India today and appears at the Tata Power and IOCL sites. Bharat AC-001 and Bharat DC-001 feature on CESL points and suit smaller batteries. AC Type 2 is common at dealer and destination locations, and a few older sites use GB/T or plain 3-pin sockets. Setting your vehicle in a charging app means the map only shows points that fit.

Public charging is billed per kilowatt hour consumed rather than per minute. Cost depends on how much energy your battery takes, whether the charger is AC or DC, and which operator runs the site. DC fast charging is quicker but priced higher per unit than AC. For Kolkata’s large electric three-wheeler fleet, where per-trip margins are thin, choosing AC charging during idle hours rather than paying for fast charging makes a material difference to daily earnings.

West Bengal policy explicitly encourages battery swapping kiosks serving two and three-wheelers, which suits Kolkata given the size of its e-rickshaw fleet. Swapping removes charging downtime by exchanging a depleted battery for a charged one in minutes, which matters most for commercial operators whose income depends on vehicle uptime. Availability varies by area and operator, so check what is running near your route before depending on it.

Start with electrical capacity. The sanctioned load at your site decides how many chargers you can run and at what power, and insufficient load is the most common reason a project stalls. You will need load approval from your distribution company, which in Kolkata means CESC or WBSEDCL depending on your area, and the state’s EV Accelerator Cell exists to speed up these approvals. You then need the right hardware mix, software to handle sessions, tariffs, payments and invoicing, and a maintenance arrangement.
