EV Charging for Property Developers in Malaysia: The EV-Ready Design Brief
If you’re designing a new office, mall or mixed-use development in Malaysia, put EV charging bays, electrical headroom and cable routes on the drawings now. Install enough chargers for opening demand, and leave a clear route to expand. A future bay with an empty conduit is useful, but it is not a working charging bay or proof that there is power to serve it.
The 60-Second Answer: Design for the Final Site, Install for Day One
Agree on two numbers before the M&E layout is locked: the number of active ports at opening and the number the infrastructure should be able to serve later. Keep them separate in the brief and budget. In this guide, 'EV-ready' means provisioned for later installation; your submitting consultant should use the local authority’s definitions on the actual drawings.
What Goes Into the Tender Before Concrete Is Poured?
Design item | Specify before tender | Evidence at handover |
|---|---|---|
Bay schedule | Show active ports and future routes separately; allow room for car doors, cable reach and circulation | Marked-up bay plan and identification labels |
Electrical design | Document coincident building load, EV power cap, feeder and distribution-board provisions | Single-line diagram, test records and configured settings |
Civil works | Reserve routes, pull points, plinth space and fire-rated penetrations where required | As-built route drawings and photo records before closure |
Connectivity and metering | Define network coverage, metering boundary, access, and billing ownership | Live connection test, meter reconciliation and operator access |
Expansion | Name what is installed now, what is provisioned, and who can approve a later connection | Costed phasing schedule and clear exclusions |
Resolve responsibilities early. The architect and civil team coordinate location and routes; the electrical consultant designs the supply and protection; the operator defines access, billing and support. Put the handover documents in the tender so they are deliverables, not extras discovered at practical completion.
How Much Power Should Phase One Reserve?
Illustrative scenario | Shared EV power | What it means |
|---|---|---|
8 active 11 kW AC ports, unrestricted | Up to 88 kW | Equipment nameplate total; do not assume the building can spare it |
8 active ports sharing 44 kW | 44 kW design cap | At full overlap, an even share is 5.5 kW per port on average |
16 active ports sharing the same 44 kW | 44 kW design cap | At full overlap, an even share is 2.75 kW per port on average; model waiting or longer sessions |
A quick check: eight vehicles each needing 18 kWh at the battery over a four-hour window need about 40 kW average grid input at an assumed 90% AC efficiency. A 44 kW cap only just clears that average; uneven arrivals, phase limits, minimum charger current and vehicle limits can still make some sessions miss their target. Run a timed scenario against expected dwell before specifying the cap.
The one mistake to avoid: treating a load cap as a promise that every occupied bay will charge at the same speed. Specify what happens when the available current is too low, what happens if the network or meter goes offline, and how the operator can see delayed or paused sessions.
Which EvGuru Charging Setup Fits Your Development?
Typical use | Hardware or system to assess | Tender question |
|---|---|---|
Offices and longer-stay mixed-use bays | Guru Swift Advance Type 2 AC wallbox, with a suitable AC design and confirmed integration | Which power and access controls are available on the selected version? |
Shared commercial AC or a pilot bay | EO Genius 2 Type 2 socketed AC, subject to stock and compatibility | Does the selected back office support the required access, metering and failure behaviour? |
Short-turn visitor or fleet bays | Guru Agility 30/40 kW DC option where dwell and demand justify it | What input, civil provision and recurring costs does the DC option add? |
For the AC proposal, compare the Guru Swift Advance and EO Genius 2. The EO listing is for an individual unit; confirm availability before specifying it for multiple bays. For a site that needs fast turnover, see the Guru Agility DC range.
Ask for a separate project quote for hardware, electrical and civil works, connectivity, and operation. EvGuru’s commercial charging service can assess the site and compare AC and DC mixes. Assign responsibility for metering, tariff changes, faults and reporting before you sign.
Which Checks Belong at Each Project Stage?
Stage | Who to involve | Decision to capture |
|---|---|---|
Concept and planning | Developer, submitting consultant and PBT | Which local planning path applies, and which bays count toward any applicable requirement |
Detailed design | M&E consultant, competent electrical professionals, utility and fire advisers as applicable | Power, protection, route, fire-safety coordination and whether a supply change is needed |
Procurement | Developer, electrical contractor and proposed charge-point operator | Equipment specification, billing ownership and who checks any licensing requirements |
Commissioning and expansion | Competent person, facility team and operator | Approved settings, safety and load tests, as-builts and the trigger for adding ports |
PLANMalaysia’s GPP EVCB addresses new and existing developments and incorporates fire-safety coordination with Jabatan Bomba dan Penyelamat Malaysia (JBPM). The Energy Commission’s GP/ST/No. 54/2025 covers EVCS electrical and competent-person requirements. The submitting team should confirm the local authority (PBT) process and the operator should confirm applicable licensing before finalising public access or charging fees.
FAQ
Do we need to install chargers on every future EV bay at handover?
Only count bays that meet the applicable project approval and its definitions. A phased approach can make sense for additional demand, but a future bay with a duct alone should not be counted as an operational charger. Ask the submitting consultant to show both counts separately.
Can dynamic load management avoid a TNB supply upgrade?
It can help where there is usable headroom and drivers stay long enough. Compare the EV energy needed during the actual parking window with the building load and allowable current on each phase. If that cannot meet the agreed service level, change the plan or investigate a supply upgrade.
Who should own the EV charging meter and billing account?
Decide before tender. The developer, future management body and operator need to agree which account pays the electricity bill, who bills drivers, and who reconciles metered use. Mixed-use sites may need different access and billing rules for tenants, residents and visitors.
Is 22 kW AC necessary on every bay?
No. For many all-day or overnight bays, a lower allocated charging rate can deliver the energy drivers need. Shorter dwell times, the car’s onboard AC limit and the building’s spare capacity should decide where faster equipment earns its cost.
What should we send EvGuru for an early assessment?
Share a parking layout, the latest single-line diagram or incoming supply information, expected active and future bay counts, and who will use the chargers. If you have a building load profile, share it too. State whether the site will charge a fee or offer public access.
Sources & Assumptions

All shared-load examples are illustrative. They assume a site-wide cap, 90% AC wall-to-battery efficiency where specified, and an even average allocation for comparison. They are not a design approval or a utility tariff estimate.
Still before tender? Request an EvGuru site assessment and share the concept plan. We can help identify what to allow for now and what to price as a later phase.
