Case Study: Chiang Mai Charge Point Operator Sourcing Success
Raj Kumar Pillai, a Charge Point Operator from Chiang Mai, compared charger factories after riders kept queueing at the only working sockets in the neighbourhood and coins jammed the old meter box. The pilot fleet was switching from lead-acid to lithium packs, which changed both the voltage profile and the safety documents the site needed.
Once the pilot site data came back, Raj Kumar Pillai selected Wanlin Fire as their EV charging equipment manufacturing partner. What closed the deal was a load-bank test report showing every outlet holding rated current, plus the NFC reader enrolling the buyer test card during the factory visit.
- 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.
- Documentation: user manuals, card-enrollment guides and installation guides in local languages for your market.
Load testing at the factory showed every outlet holding rated current for four hours, which became the deciding factor in the audit report.
Problem Analysis & Field Report: Why Global Buyers Need QR Code and NFC EV Charging Station
Every failed charger in Chiang Mai had one thing in common: nobody checked the IP rating or the payment module against the installation site before ordering. A tourist parking area in Chiang Mai served both local riders with cards and visiting riders with nothing but cash; the operator could not take payment from either group cleanly.
Field case: An airport parking operator in Chiang Mai offered NFC cards to frequent staff and QR codes to passengers, doubling the usable session rate of the previous coin-only machines.
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

EV Charger OEM Process: From Inquiry to Shipment
A typical Wanlin Fire OEM project begins with the target market, because voltage, certification, radio rules and payment habits decide the hardware configuration. A standard OEM project then follows 8 steps:
- 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
- Select a Model Line - our team recommends suitable WL-series models according to your vehicle types (48V / 60V / 72V), site conditions and target customers
- Verify Documentation - for certified models, request and verify the relevant certificate, OCPP conformance and enclosure rating documentation files
- Confirm OEM Requirements - color, logo, card design, payment modules, voltage, socket count, packaging and accessories
- Sample Evaluation - samples can be evaluated before mass production according to the agreed commercial terms
- Confirm Production - after specifications, commercial terms and OEM details are confirmed, the project can proceed to production
- Quality Inspection - chargers are inspected and tested with load-bank and aging procedures according to applicable production and quality-control standards
- 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:
- Cheng Han Wei (Government E-Mobility Project Officer, Manila, Philippines): "The first batch for Manila arrived with routine test reports inside every carton, which made our customs broker job much easier."
- Nguyen Van Hai (Condo Strata Charging Project Manager, Bandung, Indonesia): "We replaced eleven different socket and coin-box models with one Wanlin NFC line, and our maintenance calls dropped by about 28%."
- Raj Kumar Pillai (Charge Point Operator, Chiang Mai, Thailand): "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: 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.
