How to Choose an EV Home Charger in Malaysia

So you have bought an EV in Malaysia—perhaps a Tesla Model 3, a BYD Seal, or an Ora Good Cat. Relying entirely on public DC fast chargers is expensive and inconvenient. To truly experience the cost-saving benefits of EV ownership, you need a home charger (also known as an AC Wallbox).

But when you look at the options, you are faced with three main speeds: 7kW, 11kW, and 22kW. Which one is right for your home?

The 7kW EV Charger (Single-Phase)

The 7kW charger is the standard entry-level home charger. It requires a standard single-phase electrical supply, which is what most older or smaller terrace houses in Malaysia are equipped with.

• Charging Speed: Adds roughly 30-40km of range per hour of charging.
• Time to Full (60kWh battery): Approximately 8.5 hours.
• Best For: Homeowners with single-phase power who plug in their cars overnight while they sleep.

Note: If you have a single-phase supply and want to install an 11kW or 22kW charger, you will need to upgrade your home to a 3-phase supply; the cost varies, so ask TNB for a quote.

The 11kW EV Charger (Three-Phase)

For single-phase homes 7kW is enough; choose 11kW only if you have 3-phase supply and a car that accepts 11kW AC. Many newer EVs (including Tesla Model 3) accept 11kW AC, so check your car's onboard charger rating; that is the fastest speed the car can take from a home Wallbox.

• Charging Speed: Adds roughly 50-65km of range per hour.
• Time to Full (60kWh battery): Approximately 5.5 hours.
• Requirement: Your house MUST have a 3-phase electrical supply.
• Best For: Homes with 3-phase power. It provides fast, reliable overnight charging.

The 22kW EV Charger (Three-Phase)

The 22kW is the fastest AC home charger available. However, there is a catch: your car must have a 22kW onboard charger to actually use that speed.

If you plug a standard Tesla Model 3 (which has an 11kW onboard charger limit) into a 22kW Wallbox, it will still only charge at 11kW. You will have paid extra for the 22kW charger but receive zero benefit. Cars that do support 22kW AC charging include the Porsche Taycan (with the optional 22kW upgrade) and the Renault Zoe.

A Good Match: Solar + EV Charging

Charging your EV from the TNB grid will still cost you money (though much less than petrol). But if you integrate your EV charger with a home solar panel system, you can charge your car with your own renewable solar power instead of grid electricity.

Premium smart chargers, like the Autel MaxiCharger or the Wallbox Pulsar Plus (not stocked by Trexon; shown as market references), have "Solar Integration" features. They communicate with your solar inverter and ensure that only excess solar energy—energy that would otherwise be exported to TNB—is sent to your car.
