Case Study: Chiang Mai Electric Tuk-Tuk Fleet Operator Sourcing Success
Lim Wei Jie runs charging procurement for a group that operates in Chiang Mai and two neighbouring provinces, so grid voltage and rain protection mattered more than the lowest quote. Property managers across Chiang Mai were banning battery packs in lifts after a hallway fire in a nearby condo, which pushed residents toward supervised charging bays.
Once the pilot site data came back, Lim Wei Jie selected Wanlin Fire as their EV charging equipment manufacturing partner. A factory video walkthrough of the SMT line and aging racks removed the last hesitation about volume capacity.
- Source factory: Wanlin Fire runs in-house SMT lines, enclosure assembly and load-bank aging racks for two-wheeler and three-wheeler chargers
- Document pack: certificate files, user manuals, installation guides and wiring diagrams are packed with each export order
- Private label: your brand on the enclosure, LCD screen boot logo, packaging and the mobile App name
After the sample evaluation, the buyer in Chiang Mai ran a two-week trial with ten units under a covered car park and logged every session in the OCPP backend.
Problem Analysis & Field Report: Why Global Buyers Need QR Payment Charging Pile for E-Scooters
The fastest way to filter suppliers in Thailand is to ask for an OCPP session log and a routine test report, not a brochure. A market association in Chiang Mai wanted scooter charging for stall holders, but nobody wanted to collect coins or read meters at closing time.
Field case: An operator in Chiang Mai switched a 40-socket pilot to QR billing with time-based pricing; usage reports showed peak loads shifted 30% away from dinner hours within two weeks.
Why it matters for global buyers:
- QR payment works with the wallets riders already use, removing the barrier of a new App or card
- Session records give operators clear revenue data for revenue sharing with site owners
- Time-based or tiered pricing shifts demand away from peak grid hours
- No cash on site means no coin-box theft and fewer maintenance visits
- QR billing ties every session to a rider or vendor account, so operators stop guessing who owes what
- Scan-to-charge removes the need for cards, coins or staff at unattended sites in Chiang Mai

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:
- 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
- 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, 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
Importers who moved from white-label resellers to factory-direct supply in Thailand 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 30%."
- Priya Nair (E-Rickshaw Fleet Owner, Mumbai, India): "The load test report matched what we measured on site, and that has not happened with the previous two suppliers."
- Lim Wei Jie (Electric Tuk-Tuk Fleet Operator, Chiang Mai, Thailand): "Spare mainboards arrived within three weeks when a storm surge damaged two sites, which kept the network online."
Frequently Asked Questions
Q: How does the revenue settlement work for the WL-QR?
A: Payments go to the gateway account bound to the station owner. The cloud dashboard records every session, and settlement follows the agreement between the operator and the payment provider - Wanlin does not touch the funds.
Q: What happens if the 4G network drops on the WL-QR?
A: The station keeps charging and logs sessions locally, then syncs to the cloud when the connection returns. Offline mode keeps the QR payment fallback active for up to 72 hours.
Q: Does the WL-QR have fire protection?
A: Each outlet has its own fuse, leakage protector and temperature cut-off. The cabinet alarms on tamper or overheat events and pushes notifications to the management dashboard.
Q: Can the WL-QR be mounted on an existing pole?
A: Yes. The cabinet ships with wall brackets and pole clamps for 60 to 114mm diameter poles, so street-light poles and parking posts can be reused without new civil work.
Q: How are the WL-QR units packed for export?
A: Each station is wrapped, corner-protected and packed one per carton with the mounting kit and manual, four cartons per outer crate for sea freight.
