Case Study: Siem Reap Shopping Mall Facility Buyer Sourcing Success

What started as a request for twenty NFC card units from a Shopping Mall Facility Buyer in Siem Reap became a 200-unit pilot after the first OCPP test session with the local card whitelist. The fleet in Siem Reap had been charging e-bikes from wall sockets behind the office, and the landlord issued a warning after the second blown circuit.

After checking three factories against the Cambodia import rules, Agus Wibowo selected Wanlin Fire as their EV charging equipment manufacturing partner. The committee in Siem Reap ranked the bids on OCPP conformance, card-reader spare parts and local voltage tolerance, not on sticker price.

• Spare support: mainboards, NFC reader modules, payment boards and enclosures are kept as spares for after-sales replacement.
• Enclosure ratings: IP54 to IP66 waterproof and dustproof enclosures with IK08 / IK10 impact options for street installation.
• Firmware adaptation: OCPP parameters, card entitlements, power limits and time-based profiles configured before shipment.

After a factory audit and sample evaluation, the partner placed a first order of 18 charging points and expanded twice within the year.

Problem Analysis & Field Report: Why Global Buyers Need Smart EV Charging Station with OCPP

Field reports from fleets show the same pattern: equipment fails where the installation plan ignored protection, grounding and payment management. A logistics company in Siem Reap bought wallboxes from three vendors, then discovered each ran its own phone App and the fleet office had to check three dashboards for one night of charging.

Field case: A charge point operator in Siem Reap standardized on OCPP 1.6J wallboxes and moved the whole network to one open-source CSMS; adding a new site took hours instead of a vendor visit.

Why it matters for global buyers:

• OCPP 1.6J gives operators a standard session, transaction and error log that proprietary Apps cannot export
• Owners can change charging software providers without replacing the wallbox hardware
• Backend control covers pricing, card enrollment, remote start-stop and firmware updates in one place
• Standard logs satisfy utility and government requests for charging load data

Product Introduction: Wanlin Fire Smart EV Charging Station with OCPP

Wanlin Fire builds charging stations around three things riders and operators actually measure: reliable output under load, payment methods people already use and certificate files that clear customs.

Core Features:

• China-Based Manufacturing: Wanlin Fire is based in Shenzhen, China and focuses on two-wheeler and three-wheeler EV charging equipment, with in-house SMT production, enclosure assembly and per-unit load-bank and aging tests
• Certification Transparency: Real documentation for applicable certified models - instead of simply stating a product is "certified", buyers can verify the certificate and OCPP conformance documents for the exact model they intend to purchase
• NFC / RFID Card Payment: ISO 14443A compatible readers accept MIFARE-family and common ISO cards, with card enrollment, blocking and tariff control managed from the operator backend
• OCPP-Ready Control: chargers run OCPP 1.6J compliant firmware with 2.0.1 upgrade paths, so operators connect to their own CSMS instead of a closed vendor cloud
• Private Label Support: color, logo, card design, payment module, voltage, packaging, manuals and firmware parameters customized according to project requirements
• Global Market Experience: we work with distributors, operators and fleet owners worldwide and understand export steps, certification questions, local payment habits, labeling preferences and tender submission needs

Application Scenarios for Global Market

Certified EV Charger Manufacturing for Global Markets

Certification is one of the most important considerations when sourcing EV charging equipment for export. Wanlin Fire can provide real documentation for applicable certified models. Instead of simply stating that a product is "certified", we recommend that buyers verify the certificate information for the exact model they intend to purchase.

For customers exporting EV chargers, Wanlin Fire supports CE, FCC, RoHS and UKCA documentation with per-model files, and for projects where additional testing applies, the relevant documentation and testing path can be arranged for any represented model before ordering. Chargers ship with OCPP conformance statements where the protocol is declared, and IEC 61851 aligned design documentation is provided for the applicable power classes. Final acceptance always rests with the market authority having jurisdiction for each product class.

EV Charger OEM Process: From Inquiry to Shipment

A typical Wanlin Fire OEM project begins with the target market, because voltage, certification, radio rules and payment habits decide the hardware configuration. A standard OEM project then follows 8 steps:

1. Tell Us Your Target Market - Southeast Asia, South Asia, Africa, Latin America, Middle East or Europe; different markets may require different voltage, certification, card format and payment configurations
2. Select a Model Line - our team recommends suitable WL-series models according to your vehicle types (48V / 60V / 72V), site conditions and target customers
3. Verify Documentation - for certified models, request and verify the relevant certificate, OCPP conformance and enclosure rating documentation files
4. Confirm OEM Requirements - color, logo, card design, payment modules, voltage, socket count, packaging and accessories
5. Sample Evaluation - samples can be evaluated before mass production according to the agreed commercial terms
6. Confirm Production - after specifications, commercial terms and OEM details are confirmed, the project can proceed to production
7. Quality Inspection - chargers are inspected and tested with load-bank and aging procedures according to applicable production and quality-control standards
8. Shipment - products are prepared for shipment FOB, CIF or DDP according to the agreed logistics requirements

Customer Testimonials

Buyers who moved from trading-company sourcing to factory-direct card-activated charging equipment describe the difference in delivery dates and documentation:

• Nur Aisyah Hassan (RFID Charging Network Buyer, Bandung, Indonesia): "We run the OCPP backend from our office in Indonesia and the NFC stations in Bandung have not dropped a heartbeat session since commissioning."
• Raj Kumar Pillai (Government E-Mobility Project Officer, Singapore, Singapore): "The factory engineer answered our card-format question in plain language on the same day, and that settled the sourcing decision."
• Agus Wibowo (Shopping Mall Facility Buyer, Siem Reap, Cambodia): "We replaced eleven different socket and coin-box models with one Wanlin NFC line, and our maintenance calls dropped by about 40%."

Frequently Asked Questions

Q: Which OCPP operations does the WL-NOC support?

A: The wallbox supports the OCPP 1.6J core profile plus Smart Charging and Firmware Management: BootNotification, Heartbeat, Authorize, StartTransaction, StopTransaction, MeterValues, SetChargingProfile, ReserveNow and UpdateFirmware.

Q: Can we test the wallbox against our own CSMS before ordering?

A: Yes. Send the CSMS endpoint details and our engineers run a conformance session against the test environment, then share the logs before the container ships.

Q: Does the WL-NOC work when the server is unreachable?

A: Yes. With the local auth list enabled, approved NFC cards start sessions offline and the wallbox uploads the transactions when the connection returns.

Q: How do we update pricing or charge profiles remotely?

A: Through OCPP ChangeConfiguration and SetChargingProfile messages, or the wallbox management page. No site visit is needed for tariff changes.

Q: What is the minimum order for a branded WL-NOC?

A: OEM branding with logo and packaging starts at 100 units; standard neutral-brand units start at 50 units and samples of one to five units are available first.
