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

Raj Kumar Pillai, a Two-Wheeler EV Charging Network Operator in Da Nang, started with a single pilot site and needed a supplier that could scale from 10 sockets to 300 without changing platform. The fleet in Da Nang had been charging e-bikes from wall sockets behind the office, and the landlord issued a warning after the second blown circuit.

Once the pilot site data came back, Raj Kumar Pillai 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.

• Site replication: the same wallbox model had been running under a tropical downpour test for 30 days before the Vietnam order was confirmed.
• OCPP conformance: chargers ship OCPP 1.6J ready with a conformance statement, and OCPP 2.0.1 upgrade paths can be confirmed per project
• OEM / ODM depth: custom enclosure colors, logo silk-screening, voltage ranges (48V / 60V / 72V) and socket counts

The operator ran a two-month trial with 37% of riders scanning QR codes on the first day, before committing to a full rollout.

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

A charging point looks simple until it has to survive humidity, voltage dips, careless riders and an inspector with a checklist. A food delivery depot in Da Nang had 37% of riders finishing shifts with less than half a battery, but no space to charge them before the next wave.

Field case: A logistics depot in Da Nang built a charging hub with scheduling; energy costs dropped 37% after moving most sessions to off-peak hours through the OCPP charge profile.

Why it matters for global buyers:

• A structured depot hub centralizes charging under supervision instead of scattering it across informal sockets
• OCPP charge profiles shift depot load to off-peak tariffs automatically
• Session logs give fleet managers per-vehicle energy data for maintenance and cost allocation
• Standardized connectors and cabinets reduce battery damage from mismatched adapters
• Hub layouts group chargers, breakers and cabling into one serviceable zone instead of daisy-chained adapters
• Per-bay labelling and session logs let depot managers see which bikes actually charged overnight

Product Introduction: Wanlin Fire Fleet Depot Charging Hub

Wanlin Fire builds the Fleet Depot Charging Hub 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

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 a Two-Wheeler EV Charging Network Operator in Da Nang, 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

The OEM process for a Vietnam importer starts with a voltage and payment survey, then moves to samples, container QC and OCPP backend onboarding. 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): "Spare mainboards arrived within three weeks when a storm surge damaged two sites, which kept the network online."
• Priya Nair (E-Rickshaw Fleet Owner, Mumbai, India): "Riders scan the QR code and pay with the wallet they already use; we stopped explaining how to charge."
• Raj Kumar Pillai (Two-Wheeler EV Charging Network Operator, Da Nang, Vietnam): "We replaced eleven different socket models with one Wanlin line, and our maintenance calls dropped by about 37%."

Frequently Asked Questions

Q: How does the WL-FD manage total depot power?

A: The hub meters every outlet and follows an allocation profile. When total demand approaches the depot supply limit, lower-priority rows slow down instead of tripping the main breaker.

Q: Can riders be billed individually on the WL-FD?

A: Yes. Each RFID card maps to a rider account, and the CSMS exports per-rider energy totals for payroll deduction or recharge-card settlement.

Q: What fire safety measures does the WL-FD include?

A: Cabinet and trunking sensors watch temperature, and any outlet exceeding the threshold is cut off with an alarm pushed to the dashboard - a single fault never takes down the row.

Q: How are WL-FD hubs installed?

A: Wall frames carry rack rows of outlets with top-mounted trunking. A 30-outlet depot typically installs in one day with two electricians, and the commissioning checklist ships with the kit.

Q: Does the WL-FD work with our existing fleet software?

A: OCPP 1.6J connects to standard fleet and CSMS platforms. For custom APIs, our engineers review the interface document and confirm feasibility before the order.
