Case Study: Can Tho Electric Tricycle 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. Delivery riders were swapping batteries on the street, and two logistics firms had asked the operator to host a shared charging hub.

After reviewing quotes from three countries, Cheng Han Wei 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.

• In-house testing: every output is soak-tested at rated current, with overcurrent and overvoltage protection verified per unit
• Payment compliance: QR, RFID, NFC, coin and App payment modules are selected to match local payment habits and regulations
• Documentation: user manuals and installation guides in local languages for your market

After a factory audit and sample evaluation, the partner placed a first order of 28 charging points and expanded twice within the year.

Problem Analysis & Field Report: Why Global Buyers Need Swappable Battery Charging Cabinet

Field reports from fleets show the same pattern: equipment fails where the installation plan ignored protection, grounding and payment management. A delivery firm in Can Tho lost 44% of daily trips to charging downtime, because riders had to wait for a charge instead of swapping a pack in seconds.

Field case: A food delivery fleet in Can Tho placed swapping cabinets at 28 hotspots; swap time dropped below 30 minutes and trip completion rose 44% in the pilot month.

Why it matters for global buyers:

• Swapping removes charging downtime from the rider's day entirely
• Cabinets charge packs slowly and safely, extending pack life versus fast top-ups
• Centralized pack charging keeps lithium cells out of apartments and shops
• Cabinet telemetry tracks pack health, cycle counts and replacement timing
• Swapping turns a long charge wait into a quick pack exchange at the busiest hours
• Cabinet slots log pack IDs, which helps operators rotate cells evenly and extend battery life

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

Wanlin Fire positions itself as the manufacturing partner behind local charging brands, offering private label, payment customization and after-sales spare parts rather than a closed hardware box.

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

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): "Riders scan the QR code and pay with the wallet they already use; we stopped explaining how to charge."
• Cheng Han Wei (Electric Tricycle Fleet Owner, Can Tho, Vietnam): "The OCPP conformance statement arrived with the samples, which is what our customs broker asked for on the last shipment."

Frequently Asked Questions

Q: Which battery packs fit the WL-BS?

A: Standard 48V and 60V lithium packs within the slot dimensions. Buyers send the pack drawing or sample, and we confirm slot fit, connector and communication protocol.

Q: How does the WL-BS prevent charging fires?

A: Each slot monitors temperature and cuts its own channel on anomaly, the cavity is fire-retardant with insulation between slots, and smoke detection alarms the platform before escalation.

Q: Can riders swap without an attendant?

A: Yes. The rider scans, the door of a charged slot opens, they place the empty pack in and take the full one. The flow completes in under fifteen seconds and logs to the cloud.

Q: Does the WL-BS integrate with swapping platforms?

A: The cabinet exposes an API for pack management and works with OCPP-style backends. For established swapping networks, our engineers adapt the interface per their documentation.

Q: What power supply does a WL-BS site need?

A: An 8-slot cabinet draws about 3kW at full load; 12-slot units run near 5kW. Sites verify supply capacity before installation, and cabinets can stage charging across slots to flatten demand.
