Case Study: Can Tho Electric Rickshaw Fleet Owner Sourcing Success

The buying team in Can Tho had approved a European wallbox brand when the finance director asked how warranty returns would be handled from Vietnam; that question reopened the sourcing file. The fleet in Can Tho had been charging e-bikes from wall sockets behind the office, and the landlord issued a warning after the second blown circuit.

After comparing four shortlisted factories, Maria Santos 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.

• Spare support: mainboards, payment modules and enclosures are kept as spares for after-sales replacement
• Document pack: certificate files, user manuals, installation guides and wiring diagrams are packed with each export order
• Payment customization: QR code with local payment gateway, RFID cards, coin acceptor or App billing configured for the target market

After a factory audit and sample evaluation, the partner placed a first order of 22 charging points and expanded twice within the year.

Problem Analysis & Field Report: Why Global Buyers Need OCPP 1.6 Smart Wallbox

The real cost of cheap charging equipment shows up after installation: melted sockets, rejected containers and riders who stop trusting the network. A fleet owner in Can Tho could not prove how many kilowatt-hours each rider consumed, so depot cost allocation was a monthly argument.

Field case: A strata committee in Can Tho installed OCPP wallboxes and shared one 63A feeder across 22 charging points; the backend caps total load before the main breaker can trip.

Why it matters for global buyers:

• OCPP 1.6J compliance means the charger works with any CSMS, protecting the buyer from vendor lock-in
• Remote start / stop and configuration changes reduce truck rolls to the site
• Transaction and meter data feed billing, energy monitoring and maintenance logs automatically
• Firmware updates over the network keep the fleet compliant as protocols evolve to OCPP 2.0.1
• OCPP 1.6J gives property teams live status, start and stop control, and exportable session logs for the management office
• Firmware and charging profiles update remotely, so a fleet rule change in Vietnam applies without visiting each unit

Product Introduction: Wanlin Fire OCPP 1.6 Smart Wallbox

Each Wanlin Fire charger pairs a protected AC-DC stage with an OCPP-ready control board, so operators can manage sessions, pricing and diagnostics from one backend instead of five different Apps.

• 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
• 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, 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

Importers in Vietnam 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

The OEM process for a Vietnam importer starts with a voltage 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 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

Operators who standardized on one OCPP-compatible line report shorter vendor lists and fewer site visits:

• Andre Silva (EV Charger Distributor, Sao Paulo, Brazil): "The load test report matched what we measured on site, and that has not happened with the previous two suppliers."
• 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."
• Maria Santos (Electric Rickshaw Fleet Owner, Can Tho, Vietnam): "The first batch for Can Tho arrived with routine test reports inside every carton, which made our customs broker's job much easier."

Frequently Asked Questions

Q: Which OCPP versions does the WL-OC support?

A: The wallbox ships with OCPP 1.6J over WebSocket, which connects to most commercial central systems. Firmware for OCPP 2.0.1 profiles is under test and can be loaded via OTA once validated for the target backend.

Q: Can the WL-OC work without a backend server?

A: Yes. Standalone mode runs auto-start or RFID authentication with local session logs. Connecting a backend later only requires entering the server URL and station ID.

Q: How do you test OCPP compatibility before shipment?

A: Our engineers register the unit on the customer CSMS sandbox, run boot notification, status notification, start / stop transaction and meter value messages, and share the log with the buyer.

Q: What leakage protection does the WL-OC carry?

A: Type A leakage detection with AC 6mA DC smoothing monitoring, plus surge and overvoltage protection. The breaker ratings are matched to the supply voltage at the specification stage.

Q: Is the WL-OC suitable for outdoor installation?

A: With the IP65 enclosure option and IK10 front cover, the wallbox handles rain, dust and curb-side knocks from -30 to 50 degrees Celsius.
