As Singapore accelerates its journey toward a greener and cleaner transport system, electric vehicles (EVs) are becoming an increasingly common sight on our roads.

But owning an EV isn’t just about the car — it’s also about how you charge it efficiently, safely, and sustainably.

If you’re considering buying an EV or already own one, here’s a simple step-by-step guide to installing an EV charger at home.

🚗 Step 1: Check Your Home’s Electrical Supply

Every home in Singapore has a different electrical setup.

Before you choose your EV charger, it’s essential to understand what type of power supply your home uses:

Single-phase (32 amps): Supports up to a 7.4 kW charger, ideal for most HDB flats, condominiums, and smaller landed homes.
Three-phase (63 amps): Supports a 22 kW AC charger, common in larger landed properties and suitable for faster charging.

💡 Tip: Not sure what type of supply you have? Your Licensed Electrical Worker (LEW), electrician, or solar installer can confirm this for you.

⚙ Step 2: Choose the Right EV Charger

Select a charger that matches both your vehicle type and your home’s electrical supply.

Here are the most common options in Singapore:

🔌 7.4 kW AC Wall Charger – Perfect for single-phase homes; provides a full charge overnight.
⚡ 11 kW / 22 kW AC Charger – Faster charging for three-phase setups; great for households with multiple EVs or high daily mileage.

💡 Always ensure compliance:

Use LTA-approved chargers that meet TR25:2022 safety standards to avoid electrical or regulatory issues.

🧰 Step 3: Engage a Certified Installer

Installing an EV charger isn’t a DIY project — it must be carried out by a Licensed Electrical Worker (LEW) or certified installer in Singapore.

Your installer will:

Inspect your distribution board (DB) and overall electrical system.
Ensure your home’s supply can handle the additional load safely.
Install all necessary wiring, circuit breakers, and protection devices.
Submit the installation details to SP Group or EMA for approval.

This ensures your EV charger is installed safely, legally, and efficiently.

🌞 Bonus Tip: Power Your EV with Solar Energy

If you already have or plan to install solar panels, you can pair them with your EV charger for maximum sustainability.

Charging your car with solar energy helps you:

Lower your monthly electricity bills
Reduce your carbon footprint
Drive with 100% renewable energy

💡 Imagine your EV powered directly by the sun — clean, free, and future-ready.

⚡ Going Electric, the Smarter Way

With the right setup, installing an EV charger at home is simple, safe, and rewarding.

Together, we can make Singapore’s transport landscape greener — one charge at a time.
