Case Study: Medan Shopping Mall Facility Buyer Sourcing Success

Sok Dara runs charging procurement for a group that operates in Medan and two neighbouring provinces, so card payment reliability and rain protection mattered more than the lowest quote. 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, Sok Dara selected Wanlin Fire as their EV charging equipment manufacturing partner. The buyer picked Wanlin Fire because the quote included IP65 enclosures and an ISO 14443A card reader as standard, not as a paid add-on.

• Source factory: Wanlin Fire runs in-house SMT lines, enclosure assembly, card-reader test benches and load-bank aging racks for two-wheeler and three-wheeler chargers.
• OCPP conformance: chargers ship OCPP 1.6J ready with a conformance statement, and OCPP 2.0.1 upgrade paths can be confirmed per project.
• Documentation: user manuals, card-enrollment guides and installation guides in local languages for your market.

After the sample evaluation, the buyer in Medan ran a two-week trial with ten units under a covered car park and logged every card session in the OCPP backend.

Problem Analysis & Field Report: Why Global Buyers Need App and NFC EV Charger for Rentals

Every failed charger in Medan had one thing in common: nobody checked the IP rating or the payment module against the installation site before ordering. A bike-sharing startup in Medan swapped depleted batteries manually for months; rider wait times grew as the fleet expanded and the manual system stopped scaling.

Field case: A ride-hailing base in Medan installed 8 NFC bays and assigned each driver a card; average fleet readiness at shift start rose by 30% within a month.

Why it matters for global buyers:

• Multiple bays charge a full shift cohort between peaks instead of relying on home sockets
• Card identity links every charge to a driver account, which supports per-rider allowances
• Fast-charge bays with proper cabling cut turnaround time compared with domestic chargers
• Backend scheduling staggers bays to stay inside the site supply limit during shift changeover

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 card payment customization, private label 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, 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

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

• Dewi Lestari (EV Charger Distributor, Phuket, Thailand): "The first batch for Phuket arrived with routine test reports inside every carton, which made our customs broker job much easier."
• Jomar Dizon (Shopping Mall Facility Buyer, Manila, Philippines): "The OCPP conformance statement and card-reader documentation arrived with the samples, which is what our customs broker asked for on the last shipment."
• Sok Dara (Shopping Mall Facility Buyer, Medan, Indonesia): "We replaced eleven different socket and coin-box models with one Wanlin NFC line, and our maintenance calls dropped by about 30%."

Frequently Asked Questions

Q: How does the WL-NRH handle shift-change rushes?

A: Bays are sized for 15-minute top-ups, and the management page can set peak-hour caps so the rush is spread across drivers instead of becoming a queue at one socket.

Q: Can drivers pay through the ride-hailing app balance?

A: Where the operator runs its own wallet, charging credit can be deducted from the same balance. The hub exports session data that the finance team reconciles with trip earnings.

Q: What happens if a driver unplugs early?

A: The bay detects the load drop and closes the session at that point, so the driver is billed for the energy actually delivered, not a fixed window.

Q: How many bikes can one hub cycle per day?

A: An 8-bay hub with 15-minute top-ups can serve several hundred short sessions per day, while overnight charging on the same bays prepares the morning fleet.

Q: Is the hub expandable later?

A: Yes. The hub connects to the feeder through a bus that supports adding bays, so an operator can start with four bays and expand as the rider base grows.
