Case Study: Yangon Delivery Fleet Manager Sourcing Success
Most distributors start with price. This one started with a complaint log. 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, Dewi Anggraini 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.
- A 48-hour continuous-load rack cycles every station to catch relay and meter failures early
- UL, PSE and market-specific filing support is available for buyers serving North America and Japan
- OCPP builds support buyer-specified CSMS endpoints, security profiles and custom DataTransfer messages
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 Apartment Complex Charging Station
The problem showed up in the field, not in the spec sheet. A market cooperative found its charging revenue ran through one flat cash box with no record of who charged or how much.
Field case: A school district in Yangon approved the WL-CS20 after a fault-injection test: shorting one port dropped only that port while the other nineteen kept charging. The district rolled the station across six campuses the following term.
Why it matters for global buyers:
- single-rail busbars melt when every socket draws at once
- the fix was twin load groups with per-port breakers
- daily settlement exports turn charging into an auditable revenue line

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:
- A 48-hour continuous-load rack cycles every station to catch relay and meter failures early
- UL, PSE and market-specific filing support is available for buyers serving North America and Japan
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
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:
- 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

Frequently Asked Questions
Q: Why two load groups instead of one?
A: If a fault or overload hits one group, the other ten sockets keep charging, and each group draws against its own feeder cap.
Q: Can we bill riders per kWh?
A: Yes, every socket meters consumption and the station exports daily settlement files for wallet or cash reconciliation.
Q: How many stations can one CSMS manage?
A: There is no fixed limit; each WL-CS20 registers as one charge point with 20 connectors over OCPP 1.6J.
Q: What is the installation footprint?
A: Twin cabinets bolt side by side on a 1.6m wall span or back to back on a pedestal frame.
Q: Can we start with one cabinet and expand later?
A: Yes, the twin-cabinet design ships as one group first, with the second cabinet adding on the same feeder.
