Case Study: Hanoi Charge Point Operator Sourcing Success

Putu Arimbawa, a Charge Point Operator in Hanoi, started with a single pilot site and needed a supplier that could scale from 10 card sockets to 300 without changing platform. The pilot fleet was switching from lead-acid to lithium packs, which changed both the voltage profile and the safety documents the site needed.

After reviewing quotes from three countries, Putu Arimbawa 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 Vietnam had stalled two earlier orders.

• 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.
• Certification transparency: CE / FCC / RoHS / UKCA documentation is provided for applicable models, with IEC 61851 aligned design and card-reader frequency compliance files.
• Local language firmware: Thai, Vietnamese, Bahasa Indonesia and Khmer button prompts and error screens are part of the ODM option.

When the utility in Vietnam asked for load records, the OCPP transaction logs from the Hanoi site were exported in one afternoon, card IDs included.

Problem Analysis & Field Report: Why Global Buyers Need NFC Fleet Depot Charging Hub

A charging point looks simple until it has to survive humidity, voltage dips, careless riders, cloned cards and an inspector with a checklist. A delivery fleet in Hanoi grew from 20 to 80 e-bikes faster than its charging points; the depot ended up with riders fighting over sockets and batteries not fully charged before the morning shift.

Field case: A food delivery operator in Hanoi moved from loose chargers to a card-gated hub and cut charging-related rider complaints to zero in 30 days.

Why it matters for global buyers:

• A hub concentrates high-power charging on a designed circuit instead of spreading risk across domestic boards
• NFC card identity assigns every session to a rider or shift, ending blame disputes over dead batteries
• Scheduled start times shift load to off-peak hours and cut the depot electricity bill
• One backend view of all outlets replaces walking the depot counting which bikes are actually charging

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

Buyers who compare factories on price alone usually find the difference in the failure rate; Wanlin Fire competes on tested output, card-reader reliability, protection hardware and documents that survive customs inspection.

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

The EV charger OEM process starts with a short qualification call about vehicle types, voltage, site conditions and the card or wallet payments used in your market. 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 Vietnam usually mention the same shift.

• Le Quoc Bao (EV Charging Equipment Wholesaler, Chonburi, Thailand): "Spare reader modules arrived within three weeks when a storm surge damaged two sites, which kept the network online."
• Maria Santos (Utility Partnership Charging Officer, Singapore, Singapore): "We run the OCPP backend from our office in Singapore and the NFC stations in Singapore have not dropped a heartbeat session since commissioning."
• Putu Arimbawa (Charge Point Operator, Hanoi, Vietnam): "The OCPP conformance statement and card-reader documentation arrived with the samples, which is what our customs broker asked for on the last shipment."

Frequently Asked Questions

Q: How many riders can the WL-FDH handle per shift?

A: A two-row hub with 12 bays can cycle roughly 100 to 150 e-bikes per shift when riders exchange bikes at shift change, because each bay serves several bikes per night.

Q: How do we link a rider card to the payroll or incentive system?

A: Each card maps to a rider ID in the backend. Session logs export with timestamps and kWh, so the operations team can reconcile charging credit against shift output.

Q: What happens if one bay fails during the night?

A: The hub isolates the faulty bay and keeps the rest online. The management page flags the bay for maintenance, and spare bay modules are stocked for fast replacement.

Q: Can the depot hub charge different bike models?

A: Yes. Bay outlet current is set per bay, and mixed 48V and 60V fleets can be assigned to different rows with matching connectors.

Q: Is a master breaker included?

A: Yes, the hub ships with a master breaker and per-bay residual current and surge protection, sized for the feeder you declare at ordering.
