AC or DC: which charger should you use for your EV in India

AC for every day, DC for the trip

Use AC charging for your daily top up and save DC fast charging for when you are on a trip and short on time. That is the practical answer. The two differ in how much power they push into the car, what they cost you per unit, and how much of that cost actually comes from the electricity itself.

Statiq, one of India's largest charge point operators, describes its own hardware range this way: Level 2 AC chargers run from 3.3 kW up to 22 kW depending on the installation, while its DC fast chargers range from 60 kW all the way to 360 kW. That gap in power is the whole story. A home or society AC charger trickles electricity in over several hours. A DC fast charger pushes current straight into the battery pack, skipping the car's onboard charger, which is why ChargeZone's own guide to charging costs in India says a DC session typically gets a car charged "in 30 to 45 minutes" rather than overnight.

What each actually costs you

That speed costs money. ChargeZone's published guide puts public AC charging at ₹15 to ₹18 per unit in India, against ₹20 to ₹25 per unit for DC fast charging, with home charging cheaper still at ₹6 to ₹10 per unit. Part of that gap is set by Delhi, not by any one operator. The Ministry of Power's EV charging guidelines cap the service charge a network can add on top of the electricity cost, and that cap is wide apart for the two: ₹3 per unit for AC charging in solar hours (9 am to 4 pm) rising to ₹4 per unit outside those hours, against ₹11 per unit for DC fast charging in solar hours rising to ₹13 per unit outside them, according to Mercom India's reporting on the guidelines. Those ceilings exclude GST and land cost and hold until March 2028.

So a DC fast charger is allowed to add three to four times the margin an AC charger can, on top of a power bill that is itself higher because DC chargers draw far more current. That is a fair amount of what you are paying for when you choose speed.

The Bengaluru angle

Karnataka does this differently from the national solar hour framework. Under the Karnataka Electricity Regulatory Commission's combined tariff order, BESCOM and the state's other four ESCOMs, MESCOM, CESC Mysuru, HESCOM and GESCOM, all charge EV charging stations a flat ₹4.50 per unit under a dedicated category called LT 6(c), with no time of day variation, for both AC and DC connections, locked in through FY2027 to 28.

That has a direct effect on what you pay at a Bengaluru charger. Because the electricity itself costs the same ₹4.50 per unit whether the station is AC or DC, almost the entire price difference you see between an AC and a DC session in the city comes from the operator's service fee, the same fee the Ministry of Power caps nationally at a much higher level for DC. If you are weighing a slow charger in your apartment basement against a fast charger on Outer Ring Road, the electricity is not what is driving the gap. The speed premium the operator charges is.

The buyer's call

For a daily commute in Bengaluru, an AC wallbox at home or in a society parking slot is cheaper and gentler on the car, and the ₹4.50 flat Karnataka rate makes the arithmetic simple. Save DC fast charging for highway runs to Mysuru or Chennai, where the extra ₹9 or so per unit over AC buys you a battery that goes from low to usable in under an hour instead of overnight.
