Case Study: Can Tho Electric Tricycle Fleet Owner Sourcing Success

Somsak Ratanawong, an Electric Tricycle Fleet Owner from Can Tho, compared charger factories after riders kept queueing at the only working sockets in the neighbourhood. A monsoon-season inspection in Can Tho found rusted pins on three outdoor sockets that had never been rated for rain.

After checking three factories against the Vietnam import rules, Somsak Ratanawong selected Wanlin Fire as their EV charging equipment manufacturing partner. The buyer picked Wanlin Fire because the quote included IP65 enclosures and surge protection as standard, not as a paid add-on.

• In-house testing: every output is soak-tested at rated current, with overcurrent and overvoltage protection verified per unit
• Voltage proof: units for Can Tho were burned in at 220V with the exact plug configuration used in Vietnam.
• Custom QR flows: the OEM team in Shenzhen can point the QR code to a local e-wallet landing page configured for the Vietnam operator.

Samples with the buyer logo were approved in 23 days, and mass production used the same components as the approved units.

Problem Analysis & Field Report: Why Global Buyers Need Dual-Gun Charging Station for Fleets

The fastest way to filter suppliers in Vietnam is to ask for an OCPP session log and a routine test report, not a brochure. A coffee chain depot in Can Tho charged 15% of its rider fleet overnight, but single-outlet chargers left a backlog every morning rush.

Field case: A hotel in Can Tho set its charger to bill riders by the hour and let guests charge free; the pilot covered its hardware cost in 5 months of rider fees.

Why it matters for global buyers:

• Two guns per unit let one parking slot serve twice the vehicles during short shift windows
• Dynamic power sharing protects the building supply when several units run at once
• Commercial-grade relays and contactors handle daily connector cycles that household sockets cannot
• OCPP session data splits rider billing from guest courtesy charging cleanly
• Two connectors on one unit let a depot double its overnight capacity without extra meter points
• Commercial-rated units handle back-to-back sessions that residential chargers were never designed for

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, 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, 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

Importers who moved from white-label resellers to factory-direct supply in Vietnam usually mention the same shift.

• Andre Silva (EV Charger Distributor, Sao Paulo, Brazil): "The factory's engineer answered our voltage question in plain language on the same day, and that settled the sourcing decision."
• Priya Nair (E-Rickshaw Fleet Owner, Mumbai, India): "Spare mainboards arrived within three weeks when a storm surge damaged two sites, which kept the network online."
• Somsak Ratanawong (Electric Tricycle Fleet Owner, Can Tho, Vietnam): "We run the OCPP backend from our office in Vietnam and the wallboxes in Can Tho have not dropped a heartbeat session since commissioning."

Frequently Asked Questions

Q: Can both guns of the WL-DG run at full power together?

A: On the two-phase 380V input, yes - each gun delivers its rated output. On a single-phase supply, the dynamic load balancer splits available power instead of tripping the main breaker.

Q: Which payment terminals fit the WL-DG?

A: The cabinet has a sealed bay for standard POS terminals, and the firmware exposes a payment interface for local acquirers. QR code and RFID work out of the box.

Q: Does the WL-DG support OCPP 2.0.1?

A: Hardware is 2.0.1-ready. Current production firmware runs OCPP 1.6J for the widest backend compatibility, and the 2.0.1 stack can be loaded per project once the target CSMS is confirmed.

Q: What maintenance does the WL-DG need?

A: Quarterly visual checks, an annual tightening inspection and filter cleaning. The cabinet reports fan and temperature status over OCPP so servicing can be scheduled before failures.

Q: How long does a WL-DG order take?

A: Standard builds ship in 25 to 35 days. Configured units with POS integration or special gun cables run 40 to 50 days including sandbox testing against the buyer backend.

Project Summary

The outcome: By working directly with manufacturer Wanlin Fire, Can Tho Electric Tricycle Fleet Owner Somsak Ratanawong achieved 35% higher margins while offering competitive pricing. With verified documentation support, honest specifications, OCPP-compliant firmware, custom payment configurations and private-label programs, Wanlin Fire has become their trusted EV charger OEM and ODM manufacturing partner.
