Case Study: Batam Delivery Fleet Electrification Manager Sourcing Success

The buying team in Batam had approved a European wallbox brand when the finance director asked how NFC card readers would be serviced from Indonesia; that question reopened the sourcing file. Local riders were charging from home extension cords, and the municipal authority had started fining buildings for unsafe cables instead of providing metered bays.

After two rounds of document checks, Kittisak Chaiyasan selected Wanlin Fire as their EV charging equipment manufacturing partner. The decision came down to whether the charger could talk to the backend they already ran, because swapping software in Batam meant retraining every site manager.

• Factory proof: Wanlin Fire showed the Batam buyer a live OCPP 1.6J session log from an identical NFC unit still running in Shenzhen before the container shipped.
• Enclosure ratings: IP54 to IP66 waterproof and dustproof enclosures with IK08 / IK10 impact options for street installation.
• Custom card flows: the OEM team in Shenzhen configures the NFC reader, card whitelist size and QR fallback page for the Indonesia operator.

The first container shipped 20 days after order confirmation, and the second order was placed before the first one arrived.

Problem Analysis & Field Report: Why Global Buyers Need Multi-Port NFC Charging Cabinet

Before selecting a charger supplier, a buyer should look at what happens on the street: extension cords crossing sidewalks, batteries carried into apartments and coin boxes that jam after the first rain. A factory dorm in Batam banned e-bike charging indoors after a battery fire nearby, leaving 200 workers with no way to charge their commuter bikes.

Field case: A dormitory operator in Batam installed 30-port NFC cabinets in a ventilated shed with per-port breakers; the fire marshal approved the layout and riders paid per session by card.

Why it matters for global buyers:

• High port counts charge an entire dormitory or staff fleet from one engineered supply point
• Per-port breakers and over-temperature shutdown isolate a failing battery instead of taking down the row
• Card billing recovers electricity cost and caps how often each account can charge
• Outdoor-rated cabinets move charging out of corridors and lift lobbies where fire risk concentrates

Product Introduction: Wanlin Fire Multi-Port NFC Charging Cabinet

Wanlin Fire builds the Multi-Port NFC Charging Cabinet for the conditions buyers in Indonesia actually deal with: covered parking, humid air, 220V mains and heavy daily card turnover.

Core Features:

• 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
• NFC / RFID Card Payment: ISO 14443A compatible readers accept MIFARE-family and common ISO cards, with card enrollment, blocking and tariff control managed from the operator backend
• 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, card design, 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 Indonesia compare Wanlin Fire against trading companies on three points: factory test data, OCPP conformance documents and card-reader 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, RFID charging network buyers, 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, radio rules 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, card format 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, card design, 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 card-charging line report shorter vendor lists and fewer site visits:

• Pham Thi Lan (Shopping Mall Facility Buyer, Davao, Philippines): "The factory engineer answered our card-format question in plain language on the same day, and that settled the sourcing decision."
• Maria Santos (E-Bike Brand Procurement Officer, Phuket, Thailand): "We replaced eleven different socket and coin-box models with one Wanlin NFC line, and our maintenance calls dropped by about 35%."
• Kittisak Chaiyasan (Delivery Fleet Electrification Manager, Batam, Indonesia): "We run the OCPP backend from our office in Indonesia and the NFC stations in Batam have not dropped a heartbeat session since commissioning."

Frequently Asked Questions

Q: Why choose a cabinet over several single sockets?

A: A cabinet concentrates metering, protection and payment in one enclosure on one feeder, which is cheaper to install and maintain than wiring many individual smart sockets across a large parking area.

Q: What is the largest cabinet available?

A: The 30-outlet model runs on a three-phase feed and is built for estate courts and factory sheds. Bay current is set per outlet, so a cabinet can mix 5A, 10A and 13A bays.

Q: How do we top up resident cards?

A: Residents pay by QR or bank transfer and the operator adds credit to the card account from the dashboard. The cabinet itself needs no cash handling.

Q: Can the cabinet report to a government or utility platform?

A: Yes, through the OCPP 1.6J connection. Session, meter and status data export in standard format for subsidy, reporting or audit requirements.

Q: What protection is built in?

A: Each outlet has overcurrent and leakage protection, and the cabinet has a master breaker sized to the declared feeder. Surge protection is included on the input stage.
