What is an EV charger
An EV charger is the equipment that supplies electrical energy from the grid (or directly from renewable sources) to charge the battery of an electric vehicle. EV chargers come in several categories distinguished by power level, AC vs DC delivery, plug standards and intelligence (smart charging features).
For Indian EV charging, multiple standards coexist:
- Bharat AC-001 (3.3 kW): designed for two and three-wheelers
- Bharat DC-001 (10-15 kW): for early-generation four-wheelers
- Type 2 AC (3.3 to 22 kW): for passenger cars
- CCS-2 (50 to 350 kW DC): for fast charging passenger cars
- CHAdeMO (50 kW DC): older fast-charging standard
Solar integration is increasingly common, with solar carport installs, rooftop solar paired with EV charging and smart chargers that schedule charging to match solar generation.
Why EV chargers matter
EV adoption. Without charging infrastructure, EV adoption stalls.
Grid integration. Smart EV charging supports grid balancing.
Solar synergy. Daytime EV charging matches solar generation profile.
ESG contribution. Zero-emission mobility supports corporate sustainability targets.
National mission. FAME II, PM e-DRIVE and state EV policies drive deployment.
EV charger types
| Type | Power | Voltage | Use |
|---|---|---|---|
| Bharat AC-001 | 3.3 kW | 230 V single-phase | Two and three-wheelers |
| Bharat DC-001 | 10 to 15 kW | 48/72 V | Older 4W |
| Type 2 AC | 3.3 to 22 kW | 230/400 V | Passenger cars |
| CCS-2 DC | 50 to 350 kW | 200 to 1000 V | DC fast charging |
| CHAdeMO | 50 kW | up to 500 V | Older standard |
| Tesla Supercharger | 250 kW | 800 V | Tesla-specific (limited India) |
Technical deep dive
AC vs DC charging
AC charging:
- AC from grid through EV charger socket.
- Vehicle’s on-board charger (OBC) converts AC to DC.
- DC charges battery.
- Speed limited by OBC capacity (typically 3.3 to 22 kW).
DC fast charging:
- AC from grid through DC charger.
- DC charger converts AC to high-voltage DC.
- DC directly charges battery, bypassing OBC.
- Speed limited by battery acceptance rate (typically 50 to 350 kW).
Indian EV charging power levels
| Level | Power | Charging time (40 kWh battery) |
|---|---|---|
| Bharat AC-001 | 3.3 kW | 12+ hours |
| Type 2 AC home | 7.4 kW | 5 to 6 hours |
| Type 2 AC commercial | 22 kW | 2 hours |
| CCS-2 DC fast | 50 kW | 45 minutes |
| CCS-2 DC ultra-fast | 150-350 kW | 15-30 minutes |
Solar integration
| Approach | Description |
|---|---|
| Daytime charging matched to solar | Smart charger schedules to solar window |
| Net metering shared with EV | Solar offsets EV consumption via meter |
| Dedicated solar carport | Carport-integrated chargers |
| Battery buffer | Solar + battery + charger for high-power charging |
Homeowners planning a dedicated setup can follow a full solar inverter for EV charging buildout guide, and a licensed residential solar installer can size the system to the charging load. Sites using a battery buffer for high-power charging typically start from a battery sizing exercise before selecting a lithium-ion battery bank.
