Home charger · Malaysia

Your EV decides the charging speed. Not the EV charger.

Nearly every EV sold in Malaysia caps its AC charging at 7 kW or 11 kW. Our home EV charger handles up to 22 kW — but we commission it at the output your car can actually draw, so you are not paying TNB for a three-phase supply that adds nothing. Tell us your model and we’ll size the box, the cable and the breaker to it.

01 — The sizing test nobody runs for you

Will a 22 kW EV charger charge your EV any faster?

Every EV has an onboard AC charger, and it is a hard ceiling. A 22 kW EV charger feeding a car with a 7 kW onboard charger delivers 7 kW — no more. Pick your model and see the real overnight numbers before anyone quotes you for a supply upgrade.

11 kW is your ceiling

Worth 11 kW — but 22 kW adds nothing.

This car accepts 11.0 kW. If you already have three-phase supply, commissioning at 11 kW cuts the charge from 5h 46m to 3h 53m. Going to 22 kW saves a further zero minutes, because the car caps first.

Bar length = time taken; shorter is faster. A hatched bar means the wallbox is being throttled by the car, not the other way round. Assumes ~92% AC conversion efficiency and steady supply voltage; the last 10% tapers on most packs.

02 — One EV charger, three ways to commission it

The hardware is the same. The wiring is the decision.

Our Autel and Archon home EV chargers are rated to 22 kW and can be commissioned single-phase or three-phase. Which one you want depends on your TNB supply first, and your car second.

Single-phase 230 V
7.4kW

Right for most Malaysian homes. BYD Atto 3, Dolphin Standard, Ora Good Cat, and every PHEV.

  • Needs a 40 A spare way in your DB
  • Adds roughly 35–40 km of range per hour
  • Charges 20→90% overnight on every car listed above
  • No TNB supply application at all
Most common outcome
Three-phase 400 V
11kW

Worth it if you already have three-phase supply and an 11 kW car: Tesla Model 3/Y, BYD Seal, Proton e.MAS 7, Volvo EX30.

  • Requires three-phase at your meter
  • Roughly 55–60 km of range per hour
  • Cuts a large-battery charge by about a third
  • Same wallbox, different commissioning
Good, if supply exists
Three-phase 400 V
22kW

Genuinely used by a short list — smart #1/#3, Renault Zoe, some Zeekr and Porsche variants. For everything else it is a number on a box.

  • Requires three-phase plus a 32 A×3 way
  • Delivers 22 kW only if the car accepts it
  • Upgrading supply for it can cost more than the charger
  • We will tell you when it is not worth it
Rarely the answer
03 — Before you commit

Two numbers people forget to ask about

Neither of these appears on a quotation, and both change what a home charger really costs you over the years you own it.

RM 2,500

Personal income tax relief on EV charging facility cost — purchase, installation, rental or subscription. Legislated through YA 2027. Claimable once; confirm your own eligibility with LHDN.

~RM 7

Roughly what 100 km costs charging at home, at about 16 kWh/100 km on a 40–57 sen/kWh domestic block under the July 2025 TNB tariff. The same 100 km on petrol is around RM 25.

What we will not quote you for

  • A three-phase supply upgrade your car cannot use.
  • A charger with no local spare parts or firmware support.
  • An install without a Chargeman’s certificate — that is not a saving, it is an insurance problem.
  • Cable sized to the quote instead of to the run.
04 — Six steps, in order

From first message to first charge

This sequence is set by regulation, not by us — Chargeman certification and TNB notification are legally required on a fixed EV charging installation in Malaysia.

STEP 01

Send photos of your DB

Your distribution board and meter tell us your supply type and whether a spare way exists. Most quotes are settled from three photos.

Same day
STEP 02

Free on-site survey

We measure the real cable run, check earthing and the incoming main, and agree where the box goes. Fixed price is issued after this — never before.

2–4 days
STEP 03

Written fixed quote

Wallbox, cable, protection, labour and certification, itemised. Valid 30 days, with no variation on install day.

24 hours
STEP 04

TNB application, if needed

Only for three-phase upgrades or a dedicated EV meter. We prepare and submit; TNB sets the timeline.

3–8 weeks
STEP 05

Install & commissioning

An ST-registered Chargeman wires it, tests earth loop impedance and RCD trip time, then commissions the unit against your own car.

4–6 hours
STEP 06

Certificate & app handover

You get the completion certificate, test results, and your ChargeSini app paired — home charging and 2,400+ public charging points under one account.

On the day
05 — Questions we actually get asked

Straight answers

Do I need 22 kW to be future-proof?
Almost certainly not. Onboard AC chargers have not been getting faster — manufacturers put their money into DC fast charging instead. Your next EV is more likely to accept 11 kW than 22 kW. And using 22 kW at home needs three-phase supply, which is usually the expensive half of the project. Buy the home EV charger that matches the car in your porch, and use public DC when you need speed.
How long does a home charge actually take?
On 7.4 kW single-phase, a typical 60 kWh EV goes from 20% to 90% in roughly six hours — comfortably overnight. On 11 kW, about four. Anything faster than that at home is solving a problem most drivers do not have, because the car sits still for eight hours anyway.
Can I install a charger in a condominium?
Yes, but it starts as a management process rather than an electrical one: written JMB or MC approval, a cable route from the riser to your bay, and usually a dedicated sub-meter so the charging is billed to you. Expect longer lead times than a landed home. Ask us for the JMB submission pack.
Is charging from a 13 A wall socket safe?
A portable charger pulls around 2.3 kW continuously for eight to twelve hours. Household socket outlets and their wiring were not designed for that duty cycle, and the failure mode is heat at the plug. Fine as an occasional backup; not a home charging solution.
Does the installation have to be certified?
Yes. A fixed EV charging installation must be wired and certified by a competent person registered with Suruhanjaya Tenaga. An uncertified job is what an insurer will point at after a fire, and it can complicate a property sale. Certification is included in every ChargeSini quote.
Will home charging trip my main fuse?
It can, if your incoming supply is modest and the aircon, water heater and oven are all running. That is what dynamic load management is for — a CT clamp on the incoming main lets the wallbox back off automatically instead of tripping the house. We fit it whenever the survey shows headroom is tight.
Can I charge on off-peak rates?
If you are on a Time-of-Use domestic tariff, yes — schedule the session in the app and the car charges in the cheap window. Whether ToU is worth switching to depends on your whole household’s daytime consumption, not just the EV, so we will run the numbers with you rather than assume.
What is the warranty?
Two years on every AC and DC EV charger we supply, with spare parts held locally and support through the same team that runs our public network. Ask any supplier where their replacement stock physically sits before you buy.

Send three photos. Get a fixed price.

Your distribution board, your meter, and where you park. That is enough for us to tell you which home EV charger you need and roughly what it will cost — before anyone visits.

Charging times are estimates based on manufacturer onboard AC charger ratings and assume approximately 92% conversion efficiency; real sessions vary with battery temperature, state of charge and supply voltage. Verify your variant’s AC rating against its own specification sheet. Tax relief reflects legislation current at publication — confirm eligibility with LHDN. Tariff figures follow the TNB domestic schedule effective July 2025.
