Commercial EV Charging with OCPP Billing
You own the parking and the chargers. For hotels, petrol stations, malls, condos, and offices, Trexon designs and quotes AC + DC charging with OCPP billing, priced per project after a site review (DC units are selected per project, not stocked). Pairs with rooftop solar.

Site types we serve
Any commercial site with parking and a TNB supply can host EV charging. We engineer for all six site categories.
Hotels & Resorts
Overnight charging for guests — AC Type 2 at every bay. EV charging is an amenity that supports ESG reporting.
Petrol Stations
DC fast charging alongside fuel pumps. Capture the EV driver who will spend 15–20 minutes in your convenience store while charging.
Shopping Malls & Retail
Dwell-time charging lets a mall bill drivers per kWh while they shop.
Condos & Strata
Resident-only AC charging with RFID access, installed by the management corporation as a common-area system. We prepare the JMB/MC proposal and paperwork. DC charging at a strata site is likewise installed as a commercial common-area system.
Office Towers
Employee benefit charging. Supports sustainability reporting (Scope 3 reduction), GBI certification, and talent attraction for ESG-conscious employers.
Highway Rest Stops
Ultra-fast DC for inter-city EV travel. R&R operators can bill per kWh dispensed. We coordinate with the site owner and highway operator.
Why an OCPP-managed charging setup
A DC fast charger is a significant capital item. Trexon quotes the chargers, installation and billing set-up as one project, and every route starts with a booking of 20% of the system price, capped at RM20,000, credited in full.
Owned Hardware, Managed Billing
You own the hardware — chargers, cabling, protection, switchgear and signage. The OCPP billing platform handles access, tariffs and session reports.
Remote Diagnostics
Remote diagnostics via OCPP 1.6J/2.0.1, with maintenance and on-site service terms set out in your agreement.
Open OCPP Protocol — No Single-Vendor Lock-In
Every charger runs OCPP-compliant firmware, so you are not tied to a single network or software vendor.
Billing From the First Session
As soon as the charger is live, billing works: per-kWh charges are collected through your OCPP platform, with session-level reports.
Typical charger tiers (DC quoted per project, not stocked)
Three charger tiers matched to your site's dwell time and throughput requirement. Our stocked charger is the Schneider Charge Pro AC (7 and 22 kW); DC tiers are selected and quoted per project.
Slow
AC Type 2 — 7 to 22 kW
Hotels, condos, offices — overnight parking
Standard IEC 62196 Type 2 connector. 7kW single-phase or 22kW three-phase. Ideal for 4–8 hour dwell times. Integrates with building AMI meter.
Schneider Charge Pro AC stocked · Per-kWh billing
Fast
DC Fast — 60 to 120 kW
Petrol stations, highway rest stops
CCS2 + CHAdeMO combo output. 60kW adds roughly 200km of range in 30 minutes for a compatible car. The 120kW version roughly halves that time for high-throughput sites.
Not stocked — quoted per project
Ultra-Fast
Ultra-Fast — 180 to 240 kW
Premium retail flagship, EV destination hubs
Liquid-cooled cable handles full 250A output without heat limitation. Power-sharing across 4 bays from a single cabinet. Brand-premium option for luxury retail.
Not stocked — quoted per project
Billing options
You own the chargers and set the tariff. Billing runs through an OCPP platform with session-level reporting.
Per kWh
Billing Model
High-Traffic Site
Charge drivers per kWh dispensed. Suits petrol stations, shopping malls and highway rest stops with high session volume.
Per minute
Billing Model
Medium-Traffic Site
Charge per minute or per session, or link charging to parking fees. Suits office towers, condominiums and hotels with moderate but predictable session volume.
Amenity
Included Charging
Premium Location
Hotels, offices and prime sites that offer charging to guests, tenants or staff as an amenity at no charge to the driver.
Solar integration
Combine EV charging with rooftop solar to use daytime solar on site for charging. Under the Solar ATAP framework, solar-to-EV lets you use solar on site that would otherwise be exported to TNB at the lower export credit rate. Generation and charging data can support your own ESG reporting.
Solar + EV self-consumptionGeneration and charging data
From site review to live charging in 4 steps
Timelines depend on TNB supply capacity and the site works required.
01
Site Review + Demand Estimate
We review your site plan, parking bays and TNB supply capacity, and estimate likely charging demand from your parking and footfall data.
02
Proposal + Booking
Proposal accepted and the commercial booking paid (20% of the system price, capped at RM20,000, credited in full). We prepare the TNB application, the required EV charger approvals, and any JMB/MC strata paperwork.
03
Install
Civil, electrical, and charger installation, planned bay-by-bay to limit disruption to parking. TNB commissioning follows installation.
04
Live + Billing
Chargers go live on your OCPP billing platform. You receive session reports showing session counts and kWh dispensed.
Compare ways to put chargers on a site
Chargers can be bought outright or paired with solar and storage. What suits you depends on the number of bays, how long vehicles stay and who should carry the operating risk, so it is worth comparing the options. Our commercial EV charging overview explains how electrical capacity, charger mix and load management are planned, and the charger product range covers the equipment.
Site-specific guides cover hotel EV charging, shopping mall EV charging, petrol station DC fast charging and condo EV charging. Where a site has a suitable roof or carport, charging can also be paired with solar carports.
