Case Study: Da Nang Property Developer Procurement Manager Sourcing Success

Jomar Dizon, a Property Developer Procurement Manager in Da Nang, needed a charging line that property managers would approve and riders could pay for without a dedicated app. Every socket in the existing depot ran at full load during lunch hours, and the building fuse tripped twice a week in summer.

After two rounds of document checks, Jomar Dizon selected Wanlin Fire as their EV charging equipment manufacturing partner. The committee in Da Nang ranked the bids on OCPP conformance, spare part lead time and local voltage tolerance, not on sticker price.

• Source factory: Wanlin Fire runs in-house SMT lines, enclosure assembly and load-bank aging racks for two-wheeler and three-wheeler chargers
• Regional paperwork: CE / FCC / RoHS certificates plus OCPP 1.6J conformance statements were prepared for the Vietnam importer and attached to the commercial invoice.
• Documentation: user manuals and installation guides in local languages for your market

When the utility in Vietnam asked for load records, the OCPP transaction logs from the Da Nang site were exported in one afternoon.

Problem Analysis & Field Report: Why Global Buyers Need OCPP-Enabled Charging Point

Field reports from fleets show the same pattern: equipment fails where the installation plan ignored protection, grounding and payment management. A utility-backed pilot in Vietnam required remote firmware updates and session reporting, which ruled out every charger without an OCPP stack.

Field case: A delivery firm in Da Nang used OCPP transaction records to bill each rider per session, ending the flat-fee disputes that had been costing supervisor time every week.

Why it matters for global buyers:

• OCPP 1.6J compliance means the charger works with any CSMS, protecting the buyer from vendor lock-in
• Remote start / stop and configuration changes reduce truck rolls to the site
• Transaction and meter data feed billing, energy monitoring and maintenance logs automatically
• Firmware updates over the network keep the fleet compliant as protocols evolve to OCPP 2.0.1
• OCPP 1.6J gives property teams live status, start and stop control, and exportable session logs for the management office
• Firmware and charging profiles update remotely, so a fleet rule change in Vietnam applies without visiting each unit

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

Importers in Vietnam compare Wanlin Fire against trading companies on three points: factory test data, OCPP conformance documents and spare part availability.

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, 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 EV charger OEM process starts with a short qualification call about vehicle types, voltage, site conditions and the payment methods used in your market. 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 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, 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.

• Andre Silva (EV Charger Distributor, Sao Paulo, Brazil): "We replaced eleven different socket models with one Wanlin line, and our maintenance calls dropped by about 31%."
• Priya Nair (E-Rickshaw Fleet Owner, Mumbai, India): "Riders scan the QR code and pay with the wallet they already use; we stopped explaining how to charge."
• Jomar Dizon (Property Developer Procurement Manager, Da Nang, Vietnam): "The OCPP conformance statement arrived with the samples, which is what our customs broker asked for on the last shipment."

Frequently Asked Questions

Q: Which OCPP versions does the WL-OC support?

A: The wallbox ships with OCPP 1.6J over WebSocket, which connects to most commercial central systems. Firmware for OCPP 2.0.1 profiles is under test and can be loaded via OTA once validated for the target backend.

Q: Can the WL-OC work without a backend server?

A: Yes. Standalone mode runs auto-start or RFID authentication with local session logs. Connecting a backend later only requires entering the server URL and station ID.

Q: How do you test OCPP compatibility before shipment?

A: Our engineers register the unit on the customer CSMS sandbox, run boot notification, status notification, start / stop transaction and meter value messages, and share the log with the buyer.

Q: What leakage protection does the WL-OC carry?

A: Type A leakage detection with AC 6mA DC smoothing monitoring, plus surge and overvoltage protection. The breaker ratings are matched to the supply voltage at the specification stage.

Q: Is the WL-OC suitable for outdoor installation?

A: With the IP65 enclosure option and IK10 front cover, the wallbox handles rain, dust and curb-side knocks from -30 to 50 degrees Celsius.
