Case Study: Hanoi EV Charging Equipment Wholesaler Sourcing Success

What started as a request for twenty wall-mounted units from an EV Charging Equipment Wholesaler in Hanoi became a 200-unit pilot after the first OCPP test session. The fleet in Hanoi had been charging e-bikes from wall sockets behind the office, and the landlord issued a warning after the second blown circuit.

Following a three-week sample window, Ahmad Fauzi selected Wanlin Fire as their EV charging equipment manufacturing partner. What closed the deal was a load-bank test report showing every output holding rated current, plus the payment module riders already used.

• Spare support: mainboards, payment modules and enclosures are kept as spares for after-sales replacement
• Payment compliance: QR, RFID, NFC, coin and App payment modules are selected to match local payment habits and regulations
• Payment customization: QR code with local payment gateway, RFID cards, coin acceptor or App billing configured for the target market

The pilot covered a condo tower, a shophouse row and a market stall cluster in Hanoi, and the failure data pointed to one common cause.

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

Before picking a charger supplier, a buyer in Hanoi should compare how each candidate handles rain, voltage swings and payment reconciliation. A delivery operator in Hanoi found that riders left chargers running all day because payment was on trust; session revenue dropped by 43% before QR billing was added.

Field case: A university in Hanoi put a QR station at the bike rack; students scanned and paid with the local wallet, and vandalism of the coin box disappeared with the coin box.

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
• QR billing ties every session to a rider or vendor account, so operators stop guessing who owes what
• Scan-to-charge removes the need for cards, coins or staff at unattended sites in Hanoi

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.

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

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): "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): "Our logo, the App name and the payment gateway were all configured before the first container left the factory."
• Ahmad Fauzi (EV Charging Equipment Wholesaler, Hanoi, Vietnam): "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.
