Case Study: Yangon Delivery Fleet Manager Sourcing Success
The inquiry arrived on a Tuesday; by Friday a sample was on a plane. Distributors who bought generic charging boards on price alone spent the season managing burned sockets and billing disputes.
The evaluation stretched over three weekends, Thanin Srisuk 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.
- SMT lines run three shifts and every charging board gets an automated function test before enclosure
- OCPP 1.6J conformance is verified against a reference CSMS and the log travels with the shipment
- custom tariff tables and display languages are flashed at the factory, not left for the buyer to manage
Standing in the depot, the buyer ran a full 12-port load while the site breaker held and the display cycled port statuses.
Problem Analysis & Field Report: Why Global Buyers Need 12-Socket Smart Charging Station
What looked like a price problem turned out to be a reliability problem in disguise. A property manager watched a flat-rate power strip in the bike shed trip the building breaker every evening as riders plugged in after work.
Field case: A facilities company in Yangon replaced scorched generic boards with the WL-CS12 after a fire-safety review. The per-port breakers and RCD passed the review on paper and in a witnessed trip test, and the company standardized the model across its portfolio.
Why it matters for global buyers:
- unmetered flat-rate boards create billing disputes and breaker trips
- the fix was per-port metering plus a firmware load cap matched to the feeder
- property buyers now ask for trip-test records before price lists

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:
- SMT lines run three shifts and every charging board gets an automated function test before enclosure
- OCPP 1.6J conformance is verified against a reference CSMS and the log travels with the shipment
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
Sourcing teams like the process because each gate has a deliverable and a date. A standard charging station OEM project then follows 8 steps:
- 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
- Select a Model Line - our team recommends WL-series platforms for your channel and price band, or works from a reference unit you send
- Verify Documentation - request certificate files, OCPP conformance logs and test reports for the exact model before you commit
- Confirm Customization - cabinet colors, logo, firmware behavior, tariff logic, payment flows and packaging
- Sample Evaluation - verify meter accuracy, load balancing and CSMS integration on real samples before scaling
- Confirm Production - after specifications, commercial terms and OEM details are locked
- Quality Inspection - lot samples are tested and every finished station passes hipot, trip-time and burn-in racks before packing
- Shipment - cartons leave FOB, CIF or DDP according to the agreed logistics terms
Customer Testimonials
Here is what the people who actually ordered said afterward.
- Somchai Prasert (EV Charging Station Distributor, Bangkok, Thailand): "We changed the cabinet color and the decal set and kept the same power core; the line looks new without a new tooling budget."
- Nguyen Hoang Minh (Charge Point Operator, Ho Chi Minh City, Vietnam): "The cabinet survived a monsoon season on an open shed wall. That story sold more units than our ads did."
- Thanin Srisuk (Delivery Fleet Manager, Yangon, Myanmar): "When the first shipment arrived, the certificates were in the same carton as the stations."
Frequently Asked Questions
Q: How does load balancing work on the WL-CS12?
A: The station watches total site current and trims per-port output when the ceiling set in firmware is approached, so old building wiring stays safe.
Q: Can riders pay by scanning a QR code?
A: Yes, each port has its own QR linked to local wallet payment, plus RFID card and app options.
Q: Does it connect to our charging management platform?
A: It speaks OCPP 1.6J over WebSocket and has passed integration with common CSMS platforms used across Southeast Asia.
Q: What happens when the 4G signal drops?
A: Ports finish active sessions on cached tariff rules and the station reconnects automatically; local authorization keeps working offline.
Q: Can we put our brand on the cabinet?
A: Yes, logo printing, cabinet colors and custom port labels start from 50 units.
