Case Study: Hanoi Electric Rickshaw Fleet Owner Sourcing Success
Nguyen Van Hai, an Electric Rickshaw Fleet Owner in Hanoi, needed a charging line that property managers would approve and riders could pay for with a card or a wallet, without a dedicated app for every site. Delivery riders were swapping batteries on the street, and two logistics firms had asked the operator to host a shared card-gated charging hub for the neighbourhood.
Following a three-week sample window, Nguyen Van Hai 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.
- Factory proof: Wanlin Fire showed the Hanoi buyer a live OCPP 1.6J session log from an identical NFC unit still running in Shenzhen before the container shipped.
- Voltage proof: units for Hanoi were burned in at 220V with the exact plug configuration used in Vietnam.
- Local language firmware: Thai, Vietnamese, Bahasa Indonesia and Khmer button prompts and error screens are part of the ODM option.
Field engineers in Hanoi mounted the units, enrolled the first batch of NFC cards, tested QR fallback payment, and left the property team with a one-page operating checklist.
Problem Analysis & Field Report: Why Global Buyers Need OCPP 1.6 NFC Smart Wallbox
Field reports from fleets show the same pattern: equipment fails where the installation plan ignored protection, grounding and payment management. A logistics company in Hanoi bought wallboxes from three vendors, then discovered each ran its own phone App and the fleet office had to check three dashboards for one night of charging.
Field case: A charge point operator in Hanoi standardized on OCPP 1.6J wallboxes and moved the whole network to one open-source CSMS; adding a new site took hours instead of a vendor visit.
Why it matters for global buyers:
- OCPP 1.6J gives operators a standard session, transaction and error log that proprietary Apps cannot export
- Owners can change charging software providers without replacing the wallbox hardware
- Backend control covers pricing, card enrollment, remote start-stop and firmware updates in one place
- Standard logs satisfy utility and government requests for charging load data

EV Charger OEM Process: From Inquiry to Shipment
The OEM process for a Vietnam importer starts with a voltage, card format and payment survey, then moves to samples, container QC and OCPP backend onboarding. A standard OEM project then follows 8 steps:
- 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
- Select a Model Line - our team recommends suitable WL-series models according to your vehicle types (48V / 60V / 72V), site conditions and target customers
- Verify Documentation - for certified models, request and verify the relevant certificate, OCPP conformance and enclosure rating documentation files
- Confirm OEM Requirements - color, logo, card design, payment modules, voltage, socket count, packaging and accessories
- Sample Evaluation - samples can be evaluated before mass production according to the agreed commercial terms
- Confirm Production - after specifications, commercial terms and OEM details are confirmed, the project can proceed to production
- Quality Inspection - chargers are inspected and tested with load-bank and aging procedures according to applicable production and quality-control standards
- Shipment - products are prepared for shipment FOB, CIF or DDP according to the agreed logistics requirements
