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

Sok Dara, an Electric Tuk-Tuk Fleet Operator from Da Nang, compared charger factories after riders kept queueing at the only working sockets in the neighbourhood and coins jammed the old meter box. The first quotes he received were for car chargers that needed 380V input, while his depots only had 220V single-phase supply and riders paid with cards, not coins.

After comparing four shortlisted factories, Sok Dara selected Wanlin Fire as their EV charging equipment manufacturing partner. The buyer picked Wanlin Fire because the quote included IP65 enclosures and an ISO 14443A card reader as standard, not as a paid add-on.

• 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.
• Certification transparency: CE / FCC / RoHS / UKCA documentation is provided for applicable models, with IEC 61851 aligned design and card-reader frequency compliance files.
• Custom card flows: the OEM team in Shenzhen configures the NFC reader, card whitelist size and QR fallback page for the Vietnam operator.

The pilot covered a condo tower, a shophouse row and a market stall cluster in Da Nang, and the failure data pointed to one common cause: no card control and no per-session metering.

Problem Analysis & Field Report: Why Global Buyers Need App and NFC EV Charger for Rentals

Field reports from fleets show the same pattern: equipment fails where the installation plan ignored protection, grounding and payment management. A ride-hailing operator in Da Nang had drivers charging at home on domestic sockets; half the fleet arrived with low batteries because homes could not recharge fast enough between shifts.

Field case: A ride-hailing base in Da Nang installed 8 NFC bays and assigned each driver a card; average fleet readiness at shift start rose by 26% within a month.

Why it matters for global buyers:

• Multiple bays charge a full shift cohort between peaks instead of relying on home sockets
• Card identity links every charge to a driver account, which supports per-rider allowances
• Fast-charge bays with proper cabling cut turnaround time compared with domestic chargers
• Backend scheduling staggers bays to stay inside the site supply limit during shift changeover

Product Introduction: Wanlin Fire App and NFC EV Charger for Rentals

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

Buyers who compare factories on price alone usually find the difference in the failure rate; Wanlin Fire competes on tested output, card-reader reliability, protection hardware and documents that survive customs inspection.

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 EV charger OEM process starts with a short qualification call about vehicle types, voltage, site conditions and the card or wallet payments 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, 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

Operators who standardized on one OCPP-compatible card-charging line report shorter vendor lists and fewer site visits:

• Chanrithy Meas (Condo Strata Charging Project Manager, Bandar Seri Begawan, Brunei): "Riders tap the NFC card or scan the QR code and pay with the wallet they already use; we stopped explaining how to charge."
• Sithat Inthavong (E-Bike Brand Procurement Officer, Penang, Malaysia): "Spare reader modules arrived within three weeks when a storm surge damaged two sites, which kept the network online."
• Sok Dara (Electric Tuk-Tuk Fleet Operator, Da Nang, 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: How does the WL-NRH handle shift-change rushes?

A: Bays are sized for 15-minute top-ups, and the management page can set peak-hour caps so the rush is spread across drivers instead of becoming a queue at one socket.

Q: Can drivers pay through the ride-hailing app balance?

A: Where the operator runs its own wallet, charging credit can be deducted from the same balance. The hub exports session data that the finance team reconciles with trip earnings.

Q: What happens if a driver unplugs early?

A: The bay detects the load drop and closes the session at that point, so the driver is billed for the energy actually delivered, not a fixed window.

Q: How many bikes can one hub cycle per day?

A: An 8-bay hub with 15-minute top-ups can serve several hundred short sessions per day, while overnight charging on the same bays prepares the morning fleet.

Q: Is the hub expandable later?

A: Yes. The hub connects to the feeder through a bus that supports adding bays, so an operator can start with four bays and expand as the rider base grows.
