Planning to install an EV charger at your home, apartment complex, or business in India? This guide covers everything — from electrical requirements and DISCOM approvals to costs and choosing the right installer. No licence is needed, and the process is simpler than you think.
Before You Start: Key Questions
- Where will the charger be installed? — Garage wall, apartment parking bay, commercial lot, or outdoor post?
- What's your electrical capacity? — Check your sanctioned load with your DISCOM. Most homes have 3–5 kW; you may need an upgrade.
- How far is the distribution board? — Longer cable runs increase wiring costs.
- Which vehicle(s) will you charge? — All modern Indian EVs (Tata Nexon EV, MG ZS EV, Mahindra XEV 9e, etc.) use Type 2 / CCS2.
- Single or multiple chargers? — Businesses and apartment complexes typically need multiple units with load management.
Understanding Electrical Requirements
Home Installation (Level 2 AC- 7.5kW/11kW/22kW)
| Specification | Requirement |
|---|---|
| Voltage | 230V single-phase (standard Indian supply) |
| Circuit breaker | 40A 2 pole/20A 4 pole/40A 4 pole dedicated MCB along with Surge Protection device |
| Wire gauge | 6sq mm Copper (3 core)/6 sqmm Copper (5 core), if distance is higher than 25-30 meters, opt for 10sqmm to avoid power loss |
| Earthing | Proper earth connection mandatory (Type B RCCB recommended) |
| Load Planning | Home equipment load + Charger's power requirement < Total Sanctioned load |
Commercial / Public Installation (Level 2 AC 7.5kW/22kW)
| Specification | Requirement |
|---|---|
| Voltage | 230V single-phase or 415V three-phase |
| Circuit per charger | 40A 2 pole for 7.5kW and 4 pole for up to 22kW |
| Distribution board | Dedicated DB with MCBs per charger recommended |
| Networking | Wi-Fi, 4G SIM, or Ethernet for smart features |
| Mounting | Wall-mount, pedestal, or floor-standing |
DC Fast Charging
DC fast chargers have significantly higher requirements:
- 415V three-phase power mandatory
- 100A–300A per unit depending on charger capacity
- May require a dedicated HT/LT transformer from your DISCOM
- DISCOM approval and load sanction essential
- Professional installation by certified electrical contractor mandatory
The Installation Process: Step by Step
Step 1: Site Survey (Optional)
An electrician or installer visits your site to:
- Check the existing electrical panel and sanctioned load
- Measure distance from DB to charger location
- Assess earthing quality and recommend upgrades if needed
- Determine mounting location and cable routing
- Check if load enhancement is needed from DISCOM
Step 2: DISCOM Approval (3–15 days)
If your existing sanctioned load is insufficient:
- Apply to your local DISCOM (BSES, Tata Power, BESCOM, MSEDCL, etc.) for load enhancement
- Submit application online or at the local office
- For home chargers (7.5 kW): Typically need 8–10 kW sanctioned load
- For commercial: May need to apply for a new commercial connection or HT supply
Cost: ₹500–₹5,000 for load enhancement (varies by DISCOM and load required).
Note: As per Ministry of Power guidelines, no separate licence is required to install or operate an EV charging station in India. Only DISCOM approval for electrical load is needed.
Step 3: Electrical Work (2–4 hours for home; 1–2 days for commercial)
- Install dedicated MCB & SPD in the distribution board
- Run cabling from DB to charger location (through conduit/trunking)
- Install earthing if not adequate (pipe earthing or plate earthing as per IS 3043)
- Mount the charger on wall or pedestal
- Connect wiring and ensure proper connections from main line to charger
- Test the circuit — verify voltage, earth resistance etc.
Step 4: Charger Configuration (10 min-30 min)
For smart/networked chargers:
- Connect to Wi-Fi or insert 4G SIM card
- Register on the charging management platform (e.g., Zevpoint)
- Configure settings: max power, access control, pricing
- Set up payment options: UPI, RFID cards, or app-based
- Run a test charging session with a vehicle
Step 5: Go Live
Once tested, your charger is ready for use. For public/commercial installations, list your charger on google and discovery apps like Plugshare so EV drivers can discover it.
Cost Breakdown

|---|---|
| AC charger (7–22 kW) | ₹35,000 – ₹45,000 |
| DC fast charger (60 kW) | ₹ 6,00,000 – ₹8,00,000 |
|
Electrical infrastructure (varies if separate transformer required) |
₹50,000 – ₹4,00,000 |
| Civil work & signage | ₹15,000 – ₹25,000 |
| Networking & software setup | ₹4000-5000 |
Installing in Apartments and Housing Societies
This is one of the most common scenarios in urban India. Here's how to navigate it:
For Individual Flat Owners
- Your parking bay, your right: As per the Model Building Bye-Laws 2016 and various state guidelines, flat owners have the right to install EV chargers in their dedicated parking spots
- Write to your RWA/AOA informing them of your plan — you don't need their permission, only intimation
- Individual meter: Your charger should be connected to your flat's electricity meter, not the common supply
- Cable routing: Work with an electrician to route cabling from your meter to your parking bay
For RWAs / Societies (Common Charging)
- Install shared chargers in visitor parking or common areas
- Use a smart platform with per-user billing (Mobile app) so each resident pays for their own usage
- Load management ensures chargers don't overload the society's common supply
- Many state DISCOMs offer separate EV tariff connections for societies
Common Installation Mistakes to Avoid
- Skipping proper earthing — Poor earthing is dangerous and can damage the charger and vehicle. Ensure earth resistance is below 5 ohms.
- Undersizing cables — Use the correct cable gauge for the charger's rated current. Undersized cables overheat and are a fire risk.
- No dedicated circuit — Never share a circuit between an EV charger and other heavy appliances. Always install a dedicated MCB.
- Ignoring future needs — Run conduit for additional chargers now, even if you're only installing one.
- Not applying for load enhancement — If your sanctioned load is inadequate, your main breaker will trip. Apply to DISCOM before installation.
- Poor waterproofing for outdoor installs — Ensure IP65-rated chargers and weatherproof enclosures for outdoor parking.
Key Takeaways
- No licence required — Only DISCOM load approval needed
- Home installation costs ₹35,000–₹40,000 and takes less than half a day
- Proper earthing and dedicated MCB are non-negotiable safety requirements
- Apartment owners have the right to install chargers in their parking bays
- Load management is essential, allowing you to adjust charging speed as per need
- Smart chargers with OCPP give you remote monitoring, billing, and load management
