Case Study: Dhaka Hotel and Mall Facility Buyer Sourcing Success

Emma Hartfield, a Hotel and Mall Facility Buyer from Dhaka, compared charger factories after riders kept queueing at the only working sockets in the neighbourhood. Local riders were charging from home extension cords, and the municipal authority had started fining buildings for unsafe cables.

After comparing four shortlisted factories, Emma Hartfield selected Wanlin Fire as their EV charging equipment manufacturing partner. Documentation decided it: CE / FCC / RoHS files and an OCPP 1.6J conformance statement arrived with the samples, ready for customs.

• Capacity control: production slots are confirmed before the order, and pre-shipment inspection photos are shared batch by batch
• Certification transparency: CE / FCC / RoHS / UKCA documentation is provided for applicable models, with IEC 61851 aligned design
• OEM / ODM depth: custom enclosure colors, logo silk-screening, voltage ranges (48V / 60V / 72V) and socket counts

After a factory audit and sample evaluation, the partner placed a first order of 30 charging points and expanded twice within the year.

Problem Analysis & Field Report: Why Global Buyers Need Scan-to-Charge QR Code Station

Field reports from fleets show the same pattern: equipment fails where the installation plan ignored protection, grounding and payment management. A community in Dhaka set a flat fee for charging, but residents argued about fairness because heavy users paid the same as light users.

Field case: An operator in Dhaka switched a 40-socket pilot to QR billing with time-based pricing; usage reports showed peak loads shifted 30% away from dinner hours within two weeks.

Why it matters for global buyers:

• QR payment works with the wallets riders already use, removing the barrier of a new App or card
• Session records give operators clear revenue data for revenue sharing with site owners
• Time-based or tiered pricing shifts demand away from peak grid hours
• No cash on site means no coin-box theft and fewer maintenance visits

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 private label, payment customization 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, 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 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): "The OCPP conformance statement arrived with the samples, which is what our customs broker asked for on the last shipment."
• Priya Nair (E-Rickshaw Fleet Owner, Mumbai, India): "The OCPP conformance statement arrived with the samples, which is what our customs broker asked for on the last shipment."
• Emma Hartfield (Hotel and Mall Facility Buyer, Dhaka, Bangladesh): "Riders scan the QR code and pay with the wallet they already use; we stopped explaining how to charge."

Frequently Asked Questions

Q: How does the revenue settlement work for the WL-QR?

A: Payments go to the gateway account bound to the station owner. The cloud dashboard records every session, and settlement follows the agreement between the operator and the payment provider - Wanlin does not touch the funds.

Q: What happens if the 4G network drops on the WL-QR?

A: The station keeps charging and logs sessions locally, then syncs to the cloud when the connection returns. Offline mode keeps the QR payment fallback active for up to 72 hours.

Q: Does the WL-QR have fire protection?

A: Each outlet has its own fuse, leakage protector and temperature cut-off. The cabinet alarms on tamper or overheat events and pushes notifications to the management dashboard.

Q: Can the WL-QR be mounted on an existing pole?

A: Yes. The cabinet ships with wall brackets and pole clamps for 60 to 114mm diameter poles, so street-light poles and parking posts can be reused without new civil work.

Q: How are the WL-QR units packed for export?

A: Each station is wrapped, corner-protected and packed one per carton with the mounting kit and manual, four cartons per outer crate for sea freight.
