How much does it cost to fully charge an EV at home in India?

For a mid-size EV with a 50 kWh battery on a ₹7/unit domestic tariff, a full charge costs around ₹385 — or roughly ₹0.80 per km. Costs are 20–30% lower on dedicated EV tariffs available in Delhi, Maharashtra, Karnataka and Telangana.

Is home charging cheaper than public DC fast chargers?

Yes. Home AC charging costs ₹5–10/unit. Public DC fast chargers charge ₹18–25/unit. Home charging is 2–4× cheaper per km, even after accounting for the AC charger's installation cost.

Do I need a separate electricity connection for EV charging?

Not mandatory, but strongly recommended if your state has a separate EV tariff. Delhi, Maharashtra, Karnataka and Telangana DISCOMs offer EV-only connections at rates 25–35% lower than general domestic tariff.

When is the cheapest time to charge an EV in India under ToD?

Between 10 PM and 6 AM (off-peak) or 10 AM and 4 PM (solar hours). Avoid 6 PM to 10 PM — the peak window carries a 20% surcharge under the mandatory ToD tariff.

EV Home Charging Cost in India — 2026

2026-04-22

With EV sales crossing 20 lakh units in India in FY2026, the question nearly every new EV owner asks in the first week is: "What does it actually cost to charge this thing at home?". Here's the honest 2026 answer, with numbers you can cross-check on your bill.

The basic math

Cost per charge = Battery size (kWh) × domestic unit rate (₹/unit) ÷ charger efficiency. Home AC chargers are typically 88–92% efficient, so multiply battery kWh by about 1.1.

Real 2026 numbers for popular EVs

Assuming a domestic tariff of ₹7/unit (national median in 2026):

Tata Tiago EV (24 kWh, ~250 km range): ₹185 per full charge = ₹0.74/km.
Tata Nexon EV MR (30 kWh, ~325 km): ₹230/charge = ₹0.71/km.
MG ZS EV (50.3 kWh, ~460 km): ₹387/charge = ₹0.84/km.
Mahindra BE 6 (59 kWh, ~550 km): ₹454/charge = ₹0.82/km.
Hyundai Creta Electric (51 kWh, ~470 km): ₹392/charge = ₹0.83/km.
BYD Atto 3 (60 kWh, ~520 km): ₹462/charge = ₹0.89/km.

Compared to ₹6.5–8/km for petrol at ₹100/litre — EV home charging is 8–10× cheaper per km.

State-wise EV tariffs (much cheaper than domestic)

Several states have introduced dedicated EV charging tariffs below general domestic rates:

Delhi: ₹4.50/unit on a separate EV meter (single-part tariff).
Maharashtra: ₹6.02/unit EV tariff.
Karnataka: ₹5/unit via BESCOM's EV tariff.
Tamil Nadu: ₹6.65/unit for public charging, home charging on domestic slab.
Telangana: ₹6.40/unit on a registered EV connection.

Check if your DISCOM offers a separate EV meter. The ₹5,000–12,000 installation cost pays back in months for anyone driving 1,500+ km/month.

ToD hacks for EV owners

Under the new ToD tariffs (see our ToD tariff guide), charging between 10 PM and 6 AM applies the off-peak rate; between 10 AM and 4 PM, the discounted solar rate. Schedule your EV to charge in those windows via the car's app — you save 20–40% vs plugging in at 7 PM.

Solar + EV: the best of both

A 3 kW rooftop solar system generates ~12 kWh/day. A 20 km/day commuter uses ~3 kWh/day. The solar pays for the EV's entire fuel cost — and enough to cover AC and refrigeration. Payback for the combined system: 4–5 years.
