Case Study: Ho Chi Minh City Facility Management Company Buyer Sourcing Success

A sourcing visit that began with a spreadsheet ended with a field trial. Two-wheeler registrations climb across the region every quarter, but the charging hardware under bike sheds has barely changed in a decade.

Once the first 200 charging sessions reported back, Nguyen Hoang Minh selected Wanlin as their EV charging manufacturing partner. Two factors closed it: the test report matched the samples, and the answers arrived within a day.

• Enclosure gaskets are spray-rig tested to verify IP54 sealing on samples from every lot
• each model folder ships with CE, RoHS and IEC 61851 certificates plus the type-test summary
• Cabinet colors, logo printing and port labels can be changed without touching the power core

The burned-socket shelf in the maintenance room had shrunk to zero after the old boards were swapped out.

Problem Analysis & Field Report: Why Global Buyers Need RFID Card Charging Station for Fleets

What looked like a price problem turned out to be a reliability problem in disguise. A fleet yard operator documented charging losses after drivers swapped cards and the board logged nothing.

Field case: A rider co-op in Ho Chi Minh City tested the WL-RF8 offline behavior by pulling the network for a weekend. The local authorization list kept every card working and queued the logs, and the co-op ordered stations for two more depots.

Why it matters for global buyers:

• shared punch cards and keyed sockets defeat any charging audit
• the fix was a card-per-rider local list with offline authorization
• logs must queue and upload after outages, not vanish

Certified EV Charging Manufacturing for Global Markets

Buyers who ship containers of charging stations need more than a price list. The production and QC flow below is what lets a distributor open a carton and trust what is inside:

• Enclosure gaskets are spray-rig tested to verify IP54 sealing on samples from every lot
• each model folder ships with CE, RoHS and IEC 61851 certificates plus the type-test summary

Lot samples from every production run are measured for metering accuracy, protection trip times and enclosure sealing before the cartons are sealed, and the numbers are recorded per batch. A buyer can request those records with any order.

EV Charging OEM Process: From Inquiry to Shipment

The workflow below is the same one every Wanlin OEM order follows, from sample to dock. A standard charging station OEM project then follows 8 steps:

1. Tell Us Your Target Market - Southeast Asia, the Middle East, Europe, North America, Africa or Latin America; each market may require different certifications, socket standards, voltage classes and manual languages
2. Select a Model Line - our team recommends WL-series platforms for your channel and price band, or works from a reference unit you send
3. Verify Documentation - request certificate files, OCPP conformance logs and test reports for the exact model before you commit
4. Confirm Customization - cabinet colors, logo, firmware behavior, tariff logic, payment flows and packaging
5. Sample Evaluation - verify meter accuracy, load balancing and CSMS integration on real samples before scaling
6. Confirm Production - after specifications, commercial terms and OEM details are locked
7. Quality Inspection - lot samples are tested and every finished station passes hipot, trip-time and burn-in racks before packing
8. Shipment - cartons leave FOB, CIF or DDP according to the agreed logistics terms

Customer Testimonials

Three buyers who ran the same evaluation shared what they told their purchasing committees.

• Somchai Prasert (EV Charging Station Distributor, Bangkok, Thailand): "We listed the same station under our house brand and the uptime held above 99%."
• Nguyen Hoang Minh (Charge Point Operator, Ho Chi Minh City, Vietnam): "The first article matched the approved sample on meter accuracy, finish and weight. That almost never happens."
• Nguyen Hoang Minh (Facility Management Company Buyer, Ho Chi Minh City, Vietnam): "The sample arrived with the OCPP conformance log in the box. That sounds small until you have integrated a pile without one."
