Case Study: Can Tho Property Developer Procurement Manager Sourcing Success

Budi Santoso, a Property Developer Procurement Manager based in Can Tho, was sourcing card-activated charging equipment for a network that had grown faster than its charging points. The pilot fleet was switching from lead-acid to lithium packs, which changed both the voltage profile and the safety documents the site needed.

After comparing four shortlisted factories, Budi Santoso selected Wanlin Fire as their EV charging equipment manufacturing partner. The decision came down to whether the charger could talk to the backend they already ran, because swapping software in Can Tho meant retraining every site manager.

• Spare support: mainboards, NFC reader modules, payment boards and enclosures are kept as spares for after-sales replacement.
• Payment compliance: NFC, RFID, QR, coin and App payment modules are selected to match local payment habits and radio regulations.
• Firmware adaptation: OCPP parameters, card entitlements, power limits and time-based profiles configured before shipment.

When the utility in Vietnam asked for load records, the OCPP transaction logs from the Can Tho site were exported in one afternoon, card IDs included.

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

Most charging problems in growing cities are not about the vehicle, they are about the socket: wrong voltage, no access control, no payment record and no maintenance plan. A utility pilot in Can Tho asked for load records from residential chargers, and none of the installed boxes could export a standard session log.

Field case: An apartment developer in Can Tho required OCPP on every installed wallbox so the property manager could switch backend providers without replacing hardware.

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.

Why Choose Wanlin Fire as Your EV Charger OEM Manufacturer

Wanlin Fire positions itself as the manufacturing partner behind local charging brands, offering card payment customization, private label and after-sales spare parts rather than a closed hardware box.

Wanlin Fire's EV charger OEM services are suitable for: EV charger distributors, two-wheeler EV importers, e-bike brand procurement teams, e-scooter fleet operators, micromobility charging network buyers, e-rickshaw fleet owners, RFID charging network buyers, charging infrastructure wholesalers, property developers, delivery fleet managers, retail charger buyers, trading company sourcing managers, community charging project managers, utility partnership buyers and government mobility project officers.

EV Charger OEM Process: From Inquiry to Shipment

The OEM process for a Vietnam importer starts with a voltage, card format and payment survey, then moves to samples, container QC and OCPP backend onboarding. 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

Importers who moved from white-label resellers to factory-direct supply in Vietnam usually mention the same shift.

• Niran Phromma (EV Charging Equipment Wholesaler, Hanoi, Vietnam): "The first batch for Hanoi arrived with routine test reports inside every carton, which made our customs broker job much easier."
• Agus Wibowo (Ride-Hailing E-Bike Fleet Buyer, Cebu, Philippines): "Spare reader modules arrived within three weeks when a storm surge damaged two sites, which kept the network online."
• Budi Santoso (Property Developer Procurement Manager, Can Tho, Vietnam): "The load test report matched what we measured on site, and the reader enrolled our test card on the first tap; that has not happened with the previous two suppliers."

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.
