Electrical Power & EV Charging Packages

HJ Power & Energy covers electrical distribution, protection, metering, charging and load management. It is an electrical system scope—not ELV—and is assessed, designed, installed, tested and quoted separately under the applicable technical and authority requirements.

Separately Quoted Electrical Packages

Choose distribution, charging or a coordinated electrical scope

The three HJ families define the outcome. Board rating, fault protection, cable capacity, charging demand, load profile, utility interface and authority requirements are confirmed before final design.

Electrical-System Blueprint

How distribution, protection and selected energy functions work together

Power & Energy is a separately assessed electrical scope—not ELV. Board rating, circuits, protection, charging demand and authority responsibilities are confirmed for the site.

Correct Technical Boundary

Keep power design, ELV interfaces and third-party scope explicit

HJ can coordinate electrical power with ELV systems, but the engineering, protection and approval responsibilities remain separate.

Capacity, Protection & Cable Path

Electrical design

Checks demand, supply, board capacity, protective devices, earthing and cable route before equipment is selected.

Best for
Every PowerBoard and EV Charge project.
Complete scope
Available records, measured or calculated load basis, proposed circuits, protection and route constraints.
Confirm before quotation
A charger or board cannot be selected safely from product power rating alone.

Metering, App & Load Management

Optional control

Adds named monitoring or automatic load control when supported by the approved electrical architecture.

Best for
Sites with limited capacity, multiple chargers or energy reporting needs.
Complete scope
Selected meters/controllers, communication path, user roles, thresholds, tests and account handover.
Confirm before quotation
App, cloud, RFID, payment and load-balancing capability vary by platform and may require recurring services.

Authority, Utility & Competent-Person Scope

Compliance boundary

Documents submissions, inspections and external responsibilities applicable to the project.

Best for
Avoiding assumptions about approvals or utility work.
Complete scope
Named submission/inspection boundary, client documents and third-party dependencies where applicable.
Confirm before quotation
Approval, utility upgrade and competent-person services are included only when stated in the quotation.

Verified Scope

Project proof without invented package claims

HJ will attach a named electrical case only after publishable ratings, charging scope, testing and result are verified.

No exact public proof attached

No public named Power & Energy case attached

The current public portfolio does not verify a PowerBoard or EV charging scope. Security and ELV cases are not reused as electrical proof.

Clear Answers

Package selection questions

Use these answers to confirm the system boundary before model selection or quotation.

Is HJ Power & Energy part of ELV?

No. It is electrical power-system work. HJ can coordinate it with an ELV project, but the assessment, design, protection, testing, approval boundary and quotation remain separate.

Can HJ quote an EV charger before checking the electrical supply?

A preliminary budget may be possible, but the final charger, circuit, protection and load-management design require the available supply, maximum demand, cable route and parking location to be assessed.

Does EV Charge include App, RFID or payment?

Only when the selected charger/platform supports the feature and the quotation names the account, network, subscription, payment provider and commissioning scope.

What does Power & Energy Complete include?

It combines only the approved PowerBoard, metering, EV charging and load-management functions. Utility upgrades, solar, backup generation, civil works or third-party services are not implied.

Terminology checked against Suruhanjaya Tenaga EVCS Guidelines. Exact current models, regional availability and supply remain subject to the ISD catalogue.
