Case Study: Vientiane OEM ODM Sourcing Manager Sourcing Success

A sourcing visit that began with a spreadsheet ended with a field trial. Sell-through data from the region shows the winning listings are the ones with per-port metering and a working payment flow.

Once the field units logged 5,000 charging sessions, Viriya Chanthavong selected Wanlin as their EV charging manufacturing partner. The contract went to the factory that could show RCD trip-time data and sealed enclosures, not the lowest quote.

• every station completes a scripted OCPP session test against a live CSMS before it is boxed
• RCD, surge and overload protection are function-tested on samples from every lot, not by design alone
• Custom color runs as low as 50 units on existing tooling keep first launches affordable

At the condo gate, a rider scanned the QR, watched the socket lock, and plugged in without touching an attendant.

Problem Analysis & Field Report: Why Global Buyers Need E-Bike Fleet Charging Depot

The problem showed up in the field, not in the spec sheet. A delivery hub found 60 riders returning at once overwhelmed the shed wiring, tripping the main breaker every payday week.

Field case: A courier facility in Vientiane deployed the WL-DP20 with fleet card management after a single overhead account hid rider-level costs. The first month of per-rider data reshaped routes, and the facility added a second depot cabinet the next quarter.

Why it matters for global buyers:

• simultaneous plug-ins trip depot breakers without staggered windows
• the fix was per-rider metering with payroll-ready exports
• staggered charging extends rental fleet battery life

Application Scenarios for Global Market

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:

• every station completes a scripted OCPP session test against a live CSMS before it is boxed
• RCD, surge and overload protection are function-tested on samples from every lot, not by design alone

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.

Why Choose Wanlin as Your EV Charging OEM Manufacturer

Against the three suppliers shortlisted, the deciding rows were reliability data and response speed.

EV Charging OEM Process: From Inquiry to Shipment

Moving from first contact to a sealed container took a sequence the buyer could follow in writing. 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
