Case Study: Ipoh Electric Tuk-Tuk Fleet Operator Sourcing Success

What started as a request for twenty wall-mounted units from an Electric Tuk-Tuk Fleet Operator in Ipoh became a 200-unit pilot after the first OCPP test session. A monsoon-season inspection in Ipoh found rusted pins on three outdoor sockets that had never been rated for rain.

Once the pilot site data came back, Niran Phromma selected Wanlin Fire as their EV charging equipment manufacturing partner. In the end the buyer chose the supplier that could ship CE and IEC 61851 documents with the first container, since customs clearance in Malaysia had stalled two earlier orders.

• Source factory: Wanlin Fire runs in-house SMT lines, enclosure assembly and load-bank aging racks for two-wheeler and three-wheeler chargers
• 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

The pilot covered a condo tower, a shophouse row and a market stall cluster in Ipoh, and the failure data pointed to one common cause.

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

Field reports from fleets show the same pattern: equipment fails where the installation plan ignored protection, grounding and payment management. A coffee chain depot in Ipoh charged 24% of its rider fleet overnight, but single-outlet chargers left a backlog every morning rush.

Field case: A restaurant group in Malaysia put dual-gun chargers in five depot kitchens and cut the morning top-up queue from 15 minutes to zero.

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

For an Electric Tuk-Tuk Fleet Operator in Ipoh, the deciding factor is usually a factory that answers technical questions in writing within one working day.

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): "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): "The load test report matched what we measured on site, and that has not happened with the previous two suppliers."
• Niran Phromma (Electric Tuk-Tuk Fleet Operator, Ipoh, Malaysia): "Riders scan the QR code and pay with the wallet they already use; we stopped explaining how to charge."

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.
