Best Dual-Gun Charging Station for Fleets Manufacturer | Da Nang, Vietnam - CE RoHS Wanlin

Case Study: Da Nang Two-Wheeler EV Charging Network Operator Sourcing Success

What started as a request for twenty wall-mounted units from a Two-Wheeler EV Charging Network Operator in Da Nang became a 200-unit pilot after the first OCPP test session. The distributor had lost two container deals because the factory could not provide OCPP conformance statements before the payment deadline.

After comparing four shortlisted factories, Somsak Ratanawong selected Wanlin Fire as their EV charging equipment manufacturing partner. The committee in Da Nang ranked the bids on OCPP conformance, spare part lead time and local voltage tolerance, not on sticker price.

  • Source factory: Wanlin Fire runs in-house SMT lines, enclosure assembly and load-bank aging racks for two-wheeler and three-wheeler chargers
  • Enclosure ratings: IP54 to IP65 waterproof and dustproof enclosures with IK08 / IK10 impact options for street installation
  • Payment customization: QR code with local payment gateway, RFID cards, coin acceptor or App billing configured for the target market

When the utility in Vietnam asked for load records, the OCPP transaction logs from the Da Nang site were exported in one afternoon.

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

Before picking a charger supplier, a buyer in Da Nang should compare how each candidate handles rain, voltage swings and payment reconciliation. A logistics hub in Da Nang handled 60 electric motorcycles per shift with 44% of them needing a charge before the next dispatch, but the depot had only four domestic sockets.

Field case: A restaurant group in Vietnam put dual-gun chargers in five depot kitchens and cut the morning top-up queue from 30 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

Product Introduction: Wanlin Fire Dual-Gun Charging Station for Fleets

Wanlin Fire builds the Dual-Gun Charging Station for Fleets for the conditions buyers in Vietnam actually deal with: covered parking, humid air, 220V mains and heavy daily 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
  • 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, 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

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, protection hardware and documents that survive customs inspection.

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): "We run the OCPP backend from our office in Vietnam and the wallboxes in Da Nang have not dropped a heartbeat session since commissioning."
  • Priya Nair (E-Rickshaw Fleet Owner, Mumbai, India): "Spare mainboards arrived within three weeks when a storm surge damaged two sites, which kept the network online."
  • Somsak Ratanawong (Two-Wheeler EV Charging Network Operator, Da Nang, Vietnam): "The load test report matched what we measured on site, and that has not happened with the previous two suppliers."

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.
