Understanding EV Charger Basics
Before diving into the specific charger types, it’s important to understand some fundamental concepts about EV charging:
Power Output Measurements
EV chargers are typically rated by their power output in kilowatts (kW). The higher the kW rating, the faster your vehicle will charge. For example, a 7.2kW charger will replenish your battery approximately twice as fast as a 3.6kW charger.
Connector Types
Different EVs use different connector types. The most common in India include:
- Type 1 (J1772): Found on some Japanese and American vehicles
- Type 2 (Mennekes): The European standard, common on many vehicles in India
- CCS (Combined Charging System): Supports both AC and DC charging
- CHAdeMO: Used by some Japanese manufacturers
- Bharat Standard: India’s indigenous charging standard
Level 1 Charging: The Entry Point
Level 1 charging refers to using a standard household outlet (10A/15A in India) to charge your electric vehicle.
Key Characteristics:
- Power Output: Typically 1.4kW to 2.3kW
- Charging Speed: Approximately 8-15 km of range per hour of charging
- Installation Requirements: None — simply plug into an existing outlet
- Best For: Hybrid vehicles or EVs with smaller batteries, occasional charging
Advantages of Level 1 Charging:
- Accessibility: Works with any standard household outlet
- Cost-Effective: No installation costs
- Portability: Can be easily transported
Limitations:
- Slow Charging Speed: Full battery charge can take 20+ hours
- Limited Power: May not be sufficient for daily drivers with longer commutes
Level 2 Charging: The Sweet Spot for Home Use
Level 2 chargers are the most popular option for home installation, offering a perfect balance between charging speed and installation complexity.
Key Characteristics:
- Power Output: Typically 3.6kW to 22kW (most home units are 7.4kW)
- Charging Speed: Approximately 30-90 km of range per hour of charging
- Voltage Requirement: 240V supply (similar to air conditioners or large appliances)
- Best For: Daily EV drivers, primary home charging solution
Advantages of Level 2 Charging:
- Significantly Faster: Charge your vehicle overnight with ease
- Wide Availability: Many options on the market
- Moderate Cost: More affordable than DC fast chargers
- Compatibility: Works with nearly all electric vehicles
Our EV chargers come in various power ratings to suit your specific needs.
Popular Level 2 Charger Types
Wall-Mounted Units
Wall-mounted Level 2 chargers are permanently installed on a garage wall or exterior of your home:
- Power Range: Typically 7.4kW to 22kW
- Installation: Requires professional electrical work
- Features: Many include smart features like scheduling and usage monitoring
Portable Level 2 Chargers
These units offer Level 2 charging speeds but can be unplugged and transported:
- Power Range: Usually 3.6kW to 7.4kW
- Installation: Requires a 240V outlet but no permanent wiring
- Advantage: Can be taken with you when traveling
DC Fast Charging: The Speed Champion
DC Fast Chargers (sometimes called Level 3 chargers) provide the fastest charging speeds available by delivering DC power directly to your vehicle’s battery, bypassing the onboard AC/DC converter.
Key Characteristics:
- Power Output: 25kW to 350kW (home units typically 25kW to 50kW)
- Charging Speed: Up to 300 km of range in just 30 minutes (varies by vehicle)
- Installation Requirements: Specialized electrical infrastructure, often requiring three-phase power
- Best For: Quick top-ups, commercial applications, and now increasingly available for home use
Advantages of DC Fast Charging:
- Ultra-Fast Charging: Significantly reduces waiting time
- Convenience: Similar experience to traditional refueling
- High Power: Ideal for larger battery vehicles and long-distance travel
Limitations:
- High Cost: Significantly more expensive to purchase and install
- Complex Installation: Often requires electrical service upgrades
- Not All EVs Support Fast Charging: Vehicle compatibility varies

- Convenience: Monitor and control charging remotely
- Future-Proof: Updates add new features over time
- Grid Integration: Many units support grid services and demand response programs
How Does an EV Charger Work?
Understanding the mechanics behind EV charging helps in selecting the right equipment for your needs.
Basic Charging Process:
- Power Conversion: For Level 1 and Level 2 chargers, AC power from your home is delivered to the vehicle’s onboard charger, which converts it to DC power for the battery. DC fast chargers bypass this step by providing DC power directly.
- Communication Protocol: The charger and vehicle establish a connection and “handshake” to determine:
- The maximum charging rate the vehicle can accept
- Current battery state and temperature
- Safety parameters
- Charging Management: The vehicle’s battery management system regulates the charging rate, typically following this pattern:
- Initial phase: Constant current charging (faster)
- Later phase: Constant voltage charging (slower as battery fills)
- Final phase: Trickle charging (for battery health)
- Thermal Management: Both the charger and vehicle monitor temperatures to prevent overheating during the charging process.
Charging Safety Systems:
- Ground Fault Protection: Prevents electrical shocks
- Thermal Monitoring: Prevents overheating
- Automatic Shutoff: Stops charging when complete or if problems are detected
- Pilot Signal Testing: Ensures proper connection before power flows
Installation Process and Timeline
How Long Does It Take to Install an EV Charger?
The approximate installation timeline varies based on the charger type and your home’s electrical setup:
Level 1 Charging:
- Installation Time: Immediate (plug and play)
- Requirements: Standard 15A socket
Level 2 Charging:
- Assessment & Planning: 1-3 days
- Permit Acquisition(if required): 1-2 weeks
