If you can charge where you park overnight, you'll rarely think about public charging again. The trick is choosing a charger that matches your car's on-board charger and your home's electrical supply — buying more power than either can use is wasted money.
Why charge at home?
Home charging is cheaper per unit than most public stations, and it's effortless: your car is “full” every morning. For the vast majority of daily driving in India — commutes, school runs, errands — an overnight charge is more than enough. You only need public or fast charging for long trips.
Quick recommendation
- Two-wheeler or occasional top-ups: a 3.3 kW smart charging socket.
- Most car owners: a 7.4 kW single-phase AC charger — the sweet spot.
- Big battery + three-phase supply: 11 kW or 22 kW for faster charging.
Which power rating do you need?
Charger power decides how fast you refill. But remember the ceiling is your car's on-board charger — a vehicle limited to 7.4 kW won't charge any faster on a 22 kW unit.
| Charger | Supply | Range / hour* | Ideal for |
|---|---|---|---|
| 3.3 kW smart socket | Single-phase | ~15–20 km | Two-wheelers, light daily top-ups |
| 7.4 kW AC | Single-phase | ~40 km | Most homes & cars |
| 11 kW AC | Three-phase | ~60 km | Larger batteries, faster overnight |
| 22 kW AC | Three-phase | ~120 km | Cars that support 22 kW AC |
*Approximate for a typical passenger EV; actual speed depends on the car.
Single-phase vs three-phase
Most Indian homes have a single-phase connection, which comfortably supports a 7.4 kW charger. Three-phase connections (common in larger homes and commercial buildings) unlock 11 kW and 22 kW charging — but only if your car also accepts three-phase AC. If you're unsure, a 7.4 kW unit is the safe, universal choice.
Smart features worth having
“Smart” shouldn't mean gimmicky. The features that genuinely help:
- WiFi monitoring: see charging status and energy used from your phone.
- Scheduling: start charging automatically during cheaper off-peak hours.
- Load balancing: the charger backs off when other heavy appliances run, so it never trips your main supply.
- Energy tracking: know exactly what each charge costs.
The best home charger is the one you never have to think about — it just works every night, safely, at a cost you can see.
Safety essentials
An EV draws high current for hours, so charging hardware and installation must be done properly. Look for:
- Built-in overcurrent, earth-leakage (RCD) and surge protection.
- An IP54 or better enclosure if the charger is outdoors.
- Proper earthing and a dedicated circuit sized for the charger.
- Installation by a qualified electrician — never charge through ordinary extension cords.
All Chargisthan home chargers ship with these protections built in and are rated for Indian conditions — heat, dust, and voltage variation.
Installation & running costs
Installation cost depends on the distance from your meter to the parking spot, cabling, and any supply upgrade. Running cost is simply your electricity tariff per unit (kWh) times the energy your car needs — charging overnight on a domestic tariff is typically far cheaper than public fast charging.

Frequently asked questions
How long does it take to charge an EV at home?
On a 7.4 kW charger, most cars gain about 40 km of range per hour, so an overnight charge easily covers daily driving. A 3.3 kW socket is slower and better for two-wheelers or light top-ups.
Do I need a three-phase connection?
No — a 7.4 kW charger runs on a standard single-phase supply and suits most homes. Three-phase 11/22 kW only helps if both your car and wiring support it.
Is home charging safe?
Yes, with a proper EV charger and a qualified installation. Look for overcurrent, earth-leakage and surge protection, an IP-rated enclosure outdoors, and correct earthing.
