How to Choose a DC Fast EV Charger in India: 30 kW to 400 kW (2026 Guide)
A practical guide for fleets, fuel stations, hotels, real estate developers and charge point operators. Pick the right power, the right features and the right partner, with a free sizing tool.
Choose a DC fast charger by matching its power to how long your vehicles stay: 30–60 kW for offices, dealerships and city sites where cars stay an hour or more; 120–180 kW for fuel stations, highways and taxi fleets; and 240–400 kW for electric buses, trucks and busy highway hubs. In India, insist on a CCS2 connector, OCPP 1.6J or 2.0.1 support, remote diagnostics, load management and local service.
Key terms in 30 seconds
- DC fast charger
- A charger that converts grid AC to DC itself and feeds the battery directly, much faster than an AC charger.
- CCS2
- The DC charging connector used by electric cars sold in India. Type 2 is the matching AC connector.
- OCPP
- Open Charge Point Protocol. Lets a charger work with any compatible management software, so you are not locked in.
- ISO 15118 Plug & Charge
- Lets the car identify itself and start a paid session just by plugging in.
- CSMS
- Charging Station Management System: the software that monitors chargers, sets tariffs and handles billing.
- Uptime
- The share of time a charger is working and available. The single best measure of a charging network.
Which DC charger power do you need?
The right power depends on how long vehicles stay and how much energy they need, not on buying the biggest charger available. A car only charges as fast as its own battery allows.
| Power | Best for | Typical stay | Teslavolts model |
|---|---|---|---|
| 30 kW | Offices, dealerships, retail, small fleets | 1–2 hours | DC Mini 30 kW |
| 60 kW | City hubs, malls, taxi fleets | 45–90 min | DC Pro 60 kW |
| 120–180 kW | Fuel stations, highways, busy city sites | 20–45 min | DC Pro 120 / 180 kW |
| 240 kW | Highway hubs, fleet depots, buses | 15–30 min | DC Pro 240 kW |
| 320–400 kW | E-truck and bus depots, multi-gun hubs | Fast turnarounds | DC Premier Plus 320 / 360 / 400 kW |
Free sizing tool: how much charging does your site need?
Move the sliders to match your site. The tool suggests a charger power and how many charging points you need.
Assumes 90% charging efficiency and up to 75% use of each point across operating hours. A site survey confirms the final design.
10-point checklist before you buy
Tick what your shortlisted charger offers. Anything below 8 out of 10 deserves a hard question to the supplier.
Tick the features your charger offers.
What drives the cost of a DC charging station
DC chargers are quoted per site because the total depends on more than the charger itself:
- Charger hardware: rises with power and number of guns.
- Grid connection: transformer, cabling and DISCOM approvals. IEEFA notes upstream grid work can be up to 50% of a public station’s cost.
- Civil and installation: foundations, canopy, cable trenches, safety.
- Software: CSMS for monitoring, tariffs and billing.
- Operations: AMC, uptime monitoring and driver support.
Government support can cut the bill. Under PM E-DRIVE, eligible public sites can get 80% or more of upstream infrastructure costs covered.
How to set up a DC charging station, step by step
- Site survey. Check space, traffic, available power and the likely users.
- Size the load. Choose charger power and number of points with the tool above.
- Apply to your DISCOM. Get the connection or load increase approved.
- Pick the charger and software. Use the 10-point checklist; confirm OCPP compatibility.
- Install and commission. Civil work, electrical work, testing and safety checks.
- Operate and monitor. Track uptime, sessions and faults from day one.

Frequently asked questions
Which DC fast charger is best for a fuel station in India?
Most fuel stations and highway sites are best served by 120–240 kW DC chargers with two guns and CCS2 connectors, so cars can add useful range during a 20–30 minute stop.
What is the difference between AC and DC EV chargers?
An AC charger supplies AC power and the car’s onboard charger converts it, which limits speed to about 3.5–22 kW. A DC charger converts power itself and feeds the battery directly, at 30 kW to 400 kW.
What connector do DC chargers use in India?
DC fast chargers in India use the CCS2 connector, which is fitted to electric cars sold in India. AC chargers use Type 2.
Why does OCPP matter when buying an EV charger?
OCPP lets a charger work with any compatible management software, so you can switch software or join other networks without replacing hardware.
Who manufactures DC fast chargers in India?
Teslavolts designs and manufactures DC fast chargers from 30 kW to 400 kW at its HyperCharger factory in Noida, with an AI controller and cloud that detect and fix most faults remotely.
Can I get a charging station without paying upfront?
Yes. Under Teslavolts’ charging-as-a-service model, Teslavolts invests in, installs and operates chargers at suitable sites and shares the revenue with the property owner.
