Case Study: Da Nang Electric Tuk-Tuk Fleet Operator Sourcing Success

Putu Arimbawa, an Electric Tuk-Tuk Fleet Operator based in Da Nang, was rebuilding a charging rollout after an earlier batch of non-standard sockets failed inspection, and card billing was the part that had to work first. A monsoon-season inspection in Da Nang found rusted pins on three outdoor sockets that had never been rated for rain, while the card readers on the newer posts were still dry.

Once the samples finished a two-week weather test in Da Nang, Putu Arimbawa selected Wanlin Fire as their EV charging equipment manufacturing partner. In the end the buyer chose the supplier that could ship CE and IEC 61851 documents with the first container, since customs clearance in Vietnam had stalled two earlier orders.

• In-house testing: every NFC reader is enrolled, tapped and read-tested, and every output is soak-tested at rated current with overcurrent and overvoltage protection verified per unit.
• Voltage proof: units for Da Nang were burned in at 220V with the exact plug configuration used in Vietnam.
• Documentation: user manuals, card-enrollment guides and installation guides in local languages for your market.

Field engineers in Da Nang mounted the units, enrolled the first batch of NFC cards, tested QR fallback payment, and left the property team with a one-page operating checklist.

Problem Analysis & Field Report: Why Global Buyers Need NFC Fleet Depot Charging Hub

Before picking a card-activated charger supplier, a buyer in Da Nang should compare how each candidate handles rain, voltage swings, card security and payment reconciliation. A delivery fleet in Da Nang grew from 20 to 80 e-bikes faster than its charging points; the depot ended up with riders fighting over sockets and batteries not fully charged before the morning shift.

Field case: A courier company in Da Nang deployed a 24-outlet NFC hub with scheduled charging windows; the fleet left the depot at 31% average state of charge instead of the previous mixed results.

Why it matters for global buyers:

• A hub concentrates high-power charging on a designed circuit instead of spreading risk across domestic boards
• NFC card identity assigns every session to a rider or shift, ending blame disputes over dead batteries
• Scheduled start times shift load to off-peak hours and cut the depot electricity bill
• One backend view of all outlets replaces walking the depot counting which bikes are actually charging

Product Introduction: Wanlin Fire NFC Fleet Depot Charging Hub

Each Wanlin Fire charger pairs a protected AC-DC stage with an OCPP-ready control board and a card reader, so operators can manage cards, sessions, pricing and diagnostics from one backend instead of five different Apps.

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

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

• Sok Dara (RFID Charging Network Buyer, Cebu, Philippines): "Spare reader modules arrived within three weeks when a storm surge damaged two sites, which kept the network online."
• Tan Kah Hoe (EV Charging Equipment Wholesaler, Medan, Indonesia): "Riders tap the NFC card or scan the QR code and pay with the wallet they already use; we stopped explaining how to charge."
• Putu Arimbawa (Electric Tuk-Tuk Fleet Operator, Da Nang, Vietnam): "We replaced eleven different socket and coin-box models with one Wanlin NFC line, and our maintenance calls dropped by about 31%."

Frequently Asked Questions

Q: How many riders can the WL-FDH handle per shift?

A: A two-row hub with 12 bays can cycle roughly 100 to 150 e-bikes per shift when riders exchange bikes at shift change, because each bay serves several bikes per night.

Q: How do we link a rider card to the payroll or incentive system?

A: Each card maps to a rider ID in the backend. Session logs export with timestamps and kWh, so the operations team can reconcile charging credit against shift output.

Q: What happens if one bay fails during the night?

A: The hub isolates the faulty bay and keeps the rest online. The management page flags the bay for maintenance, and spare bay modules are stocked for fast replacement.

Q: Can the depot hub charge different bike models?

A: Yes. Bay outlet current is set per bay, and mixed 48V and 60V fleets can be assigned to different rows with matching connectors.

Q: Is a master breaker included?

A: Yes, the hub ships with a master breaker and per-bay residual current and surge protection, sized for the feeder you declare at ordering.
