Home EV Charger Installation in Malaysia: Landed Homes, Condos, Costs and Tax Relief
Charging at home is the cheapest and most convenient way to run an EV in Malaysia. This guide covers which charger suits your home, the rules from TNB and Suruhanjaya Tenaga, what condo owners need from the JMB, and what installation really costs.
Which charger size do you need?
| Charger | Supply needed | Power | Roughly adds per hour of charging* |
|---|---|---|---|
| Portable "granny" cable from a 13A socket | Single-phase | about 2.3 kW | 10–15 km |
| Wall charger 32 A | Single-phase | about 7.4 kW | 35–50 km |
| Wall charger 16 A × 3 | Three-phase | 11 kW | 50–70 km |
| Wall charger 32 A × 3 | Three-phase | 22 kW | Limited by the car's onboard charger (many cars accept only 7–11 kW AC) |
*Range per hour depends on the car's efficiency (typically 14–20 kWh per 100 km). These are rough estimates for planning.
For most homes, a 7.4 kW single-phase charger fully recharges a typical EV overnight. A 60 kWh battery from 20% to 80% (36 kWh) takes about 5 hours at 7.4 kW.
Do not rely on a normal 13A socket for daily charging. TNB states that Mode 1 charging (plugging a car directly into a socket without a control and protection device) is not allowed (Motorist). Portable chargers with built-in protection (Mode 2) are for occasional use only; a 13A socket circuit is not designed for hours of continuous full load.
Do you need TNB approval?
According to the myTNB FAQ, you do not need TNB approval to install a home charger. You only need to apply to TNB if adding the charger takes your home's total load above 10 kW, in which case you upgrade to three-phase supply (myTNB FAQ). See upgrading to three-phase.
A quick way to check your supply: look at the TNB meter. Single-phase homes have 2 incoming wires; three-phase homes have 4.
What the installation must include
The charger must be installed by an electrical contractor registered with Suruhanjaya Tenaga, and the work tested and certified. A proper installation includes:
- A load check of your existing supply and DB, so the charger does not overload the main switch.
- A dedicated circuit from the DB to the charger, sized for continuous load. A 32 A charger normally needs at least 6 mm² cable; longer runs may need larger cable.
- Its own protective device and residual current protection. Many chargers need a Type A RCD with built-in DC fault detection, or a Type B RCD; follow the charger manufacturer's requirement. ST's domestic wiring guideline lists Type B and Type F RCDs as recommended where inverter-type equipment is used (GP/ST/No.39/2024, section 7.3).
- Earthing checked and tested.
- A charger with the ST-SIRIM approval where required, mounted at a suitable height, protected from rain if outdoors.
- Testing and Borang G/H on completion.
ST has also published dedicated guidance on EV charging systems. Industry sources refer to an updated ST guideline issued in 2025; ask your contractor which edition they follow, and check the ST website for the current version.
Installing an EV charger in a condo
Condo installations need more planning because the parking bay is common or accessory property:
- JMB or MC consent. Get written approval before any work, under the building's by-laws and the Strata Management Act framework.
- Building load check. The management or its electrical consultant confirms the building's supply can take more chargers.
- Cable route and metering. The cable runs from your unit's DB, or from a separate supply with a sub-meter, to your bay. Long runs in car parks increase cost.
- Approved contractor. Many JMBs require an ST-registered contractor with insurance and a method statement.
Bring a simple proposal to your JMB: charger model, cable route, how electricity is billed, and the contractor's ST registration. We can prepare the documents for you.
How much does it cost?
| Item | Luco Group price |
|---|---|
| Site assessment and load check | RM150 (fully deducted if you proceed) |
| 7.4 kW charger installation, cable up to 10 m, charger not included | RM1,480 |
| Extra cable | RM38 per metre |
| Dedicated sub-DB for the charger (if needed) | RM480 |
| Full package including a smart charger | from RM4,280 |
For comparison, EvGuru advertises single-phase installations from RM1,590 (EvGuru). Condo installations usually cost more because of longer cable routes in the car park.
The RM2,500 EV charger tax relief
Malaysia offers individual income tax relief of up to RM2,500 a year for the purchase, installation, rental or subscription of EV charging equipment, available until year of assessment 2027 (MIDA; MGTC). Keep your invoice and receipt in your name. Check LHDN's current relief list when you file, as eligibility details can change.
Frequently asked questions
Can I use the charger that came with the car? The portable cable is fine occasionally. For daily charging, a wall charger on a dedicated circuit is safer and much faster.
Will charging at home make my bill much higher? A car driven 1,500 km a month at about 15 kWh per 100 km uses about 225 kWh. At around 44 sen per kWh before surcharges, that is roughly RM100 a month. See how your TNB bill is calculated.
Does my DB need upgrading? If your DB has no spare way, no RCCB, or an old main switch, it may need upgrading first. We check this during the site assessment.
Can I install an 11 kW charger on single-phase? No. 11 kW and 22 kW chargers need three-phase supply.
