Case Study: Vientiane Two-Wheeler EV Charging Network Operator Sourcing Success

Chanrithy Meas, a Two-Wheeler EV Charging Network Operator in Vientiane, walked into a supplier search with three hard requirements: OCPP compatibility, real certificate files and a payment method riders already use. Electric motorcycle registrations in Laos were climbing faster than the utility could approve new meter points, so shared charging rows became the practical answer.

Once the samples finished a two-week weather test in Vientiane, Chanrithy Meas selected Wanlin Fire as their EV charging equipment manufacturing partner. The decision came down to OCPP conformance, real certificate files and a factory that would modify the socket count without redesigning the board.

• Export experience: the factory ships charging equipment to Southeast Asia, South Asia, Africa, Latin America and the Middle East
• Certification transparency: CE / FCC / RoHS / UKCA documentation is provided for applicable models, with IEC 61851 aligned design
• OEM / ODM depth: custom enclosure colors, logo silk-screening, voltage ranges (48V / 60V / 72V) and socket counts

Load testing at the factory showed every socket holding rated current for four hours, which became the deciding factor in the audit report.

Problem Analysis & Field Report: Why Global Buyers Need App Payment Timer Charger for E-Bikes

Before selecting a charger supplier, a buyer should look at what happens on the street: extension cords crossing sidewalks, batteries carried into apartments and sockets that stop working after the first rain. A motorcycle shop in Laos offered charging as a side service but lost money because customers left bikes plugged in overnight.

Field case: A market operator in Vientiane set a timer charger at a flat rate per hour; the hogging problem disappeared and the bay turned over 15 times a night.

Why it matters for global buyers:

• Dual coin and App payment covers users with and without smartphone wallets
• Timer countdowns end overstay and make socket turnover predictable
• Coin operation works during power or network outages when App payment cannot reach the server
• Session logs reconcile coin drops with App records for operators and auditors
• Timer control caps each session, so one rider cannot occupy a public bay for the whole evening
• Coin and app options suit markets where cash is still common and riders without smartphones are regulars

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

Importers in Laos compare Wanlin Fire against trading companies on three points: factory test data, OCPP conformance documents and spare part availability.

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, 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

A typical Wanlin Fire OEM project begins with the target market, because voltage, certification and payment habits decide the hardware configuration. 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 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, 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 charging equipment describe the difference in delivery dates and documentation:

• Andre Silva (EV Charger Distributor, Sao Paulo, Brazil): "Riders scan the QR code and pay with the wallet they already use; we stopped explaining how to charge."
• Priya Nair (E-Rickshaw Fleet Owner, Mumbai, India): "The OCPP conformance statement arrived with the samples, which is what our customs broker asked for on the last shipment."
• Chanrithy Meas (Two-Wheeler EV Charging Network Operator, Vientiane, Laos): "We replaced eleven different socket models with one Wanlin line, and our maintenance calls dropped by about 15%."

Frequently Asked Questions

Q: Why keep coin payment on the WL-TM?

A: In many markets a large share of two-wheeler riders still pay cash. The dual-flow design keeps those riders served while the QR option captures card and wallet users.

Q: How is the coin box emptied and audited?

A: The box sits behind a security lock. The counter log records total coins per day, so the collection tally can be checked against physical coins in minutes.

Q: Can pricing differ by outlet on the WL-TM?

A: Coin pricing is set per cabinet, while app pricing can differ per outlet. Operators commonly run uniform coin pricing and time-based app tiers.

Q: What happens when the timer ends?

A: The outlet powers off and the LED goes dark, freeing the slot for the next rider. The vehicle cannot keep drawing current once the session closes.

Q: Does the WL-TM replace old resistor-panel stations?

A: Yes. It mounts on the same wall footprint and reuses the existing supply in most retrofits, which is why property managers choose it for legacy upgrades.
