Case Study: Can Tho Ride-Hailing E-Bike Fleet Buyer Sourcing Success

Jose Rafael Cruz, a Ride-Hailing E-Bike Fleet Buyer based in Can Tho, spent a year buying two-wheeler chargers from three suppliers before one tender in Vietnam made him rewrite the whole shortlist. The pilot fleet was switching from lead-acid to lithium packs, which changed both the voltage profile and the safety documents the site needed.

Following a three-week sample window, Jose Rafael Cruz 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.

• Factory proof: Wanlin Fire showed the Can Tho buyer a live OCPP 1.6J session log from an identical NFC unit still running in Shenzhen before the container shipped.
• Payment compliance: NFC, RFID, QR, coin and App payment modules are selected to match local payment habits and radio regulations.
• Local language firmware: Thai, Vietnamese, Bahasa Indonesia and Khmer button prompts and error screens are part of the ODM option.

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 Scan-to-Charge EV Charging Station

The real cost of cheap charging equipment shows up after installation: melted sockets, rejected containers and riders who stop trusting the network because the payment reader failed twice. A hotel in Can Tho tried QR-only charging, but the older regular guests without mobile wallets could not start a session.

Field case: A shopping district in Can Tho installed QR plus NFC stations and saw the share of uncollectable charging drop because every session ended with either a card ID or a wallet receipt.

Why it matters for global buyers:

• Dual QR and NFC acceptance covers residents with cards and visitors with phones in one station
• Mobile wallet payment removes the need to issue cards to one-off users
• Both channels write to the same backend, so revenue reports do not split across systems
• Visitors who cannot use the local card system can still pay, which raises utilization

Product Introduction: Wanlin Fire Scan-to-Charge EV Charging Station

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 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.

• Putu Arimbawa (Electric Motorcycle Importer, Kuala Lumpur, Malaysia): "We replaced eleven different socket and coin-box models with one Wanlin NFC line, and our maintenance calls dropped by about 30%."
• Aung Ko Min (Electric Tuk-Tuk Fleet Operator, Cebu, Philippines): "Our logo, the App name, the card design and the payment gateway were all configured before the first container left the factory."
• Jose Rafael Cruz (Ride-Hailing E-Bike Fleet Buyer, Can Tho, Vietnam): "Spare reader modules arrived within three weeks when a storm surge damaged two sites, which kept the network online."

Frequently Asked Questions

Q: Why offer both QR and NFC on one station?

A: Local riders in most Southeast Asian cities pay by e-wallet QR code, while residents, staff and tourist renters often hold an NFC card. Supporting both on one reader row lets one station serve walk-in and registered users without two devices.

Q: How does the QR payment flow work?

A: The rider scans the printed QR code, the local payment gateway opens with the outlet number, and charging starts once payment clears. A receipt with kWh and duration is returned to the phone.

Q: Can we rebrand the QR landing page for our market?

A: Yes. The OEM team points the QR code to your local e-wallet landing page and can brand the page with your logo before the first batch ships.

Q: What happens when a rider taps an NFC card?

A: The card is checked against the whitelist and a prepaid or postpaid account, then the same outlet logic runs as a QR session. Both paths report to the same OCPP backend.

Q: Which markets suit the WL-QNH best?

A: It fits markets where QR wallets dominate but cards still matter, such as Indonesia, Vietnam, the Philippines and Malaysia, plus tourist-heavy areas where foreign visitors carry cards instead of local wallets.
