Case Study: Yangon Charge Point Operator Sourcing Success
It looked like a routine RFQ until the buyer mentioned what the last batch cost them. The margin squeeze in the category pushes buyers toward factory-direct programs with type-test evidence.
After the operator's own four-week load-balance logging test, Aung Kyaw Moe selected Wanlin as their EV charging manufacturing partner. The buyer admitted the deciding factor was a supplier who answered protocol questions in hours, not weeks.
- incoming contactors, RCDs and metering ICs are batch-checked against the approved BOM before assembly starts
- CE, RoHS and IEC 61851-1 documentation ships with every commercial order
- Branded cabinets, multilingual manuals, spare kits and QR decals are handled by the same production team
At the taxi queue stand, drivers tapped RFID cards while the station logged each session to the cloud.
Problem Analysis & Field Report: Why Global Buyers Need OCPP 1.6J Compliant Charging Pile
Nobody flagged it at the packing station; the market flagged it first. A network operator watched reservation and remote-start features silently fail on piles that only implemented half the core profile.
Field case: A utility program in Yangon required a witnessed OCPP conformance log before any pile could join the pilot. The WL-OP16 arrived with the log and a scripted session transcript, cleared the review in one pass, and the pilot expanded from 20 to 200 piles.
Why it matters for global buyers:
- OCPP claims without conformance logs stall utility tenders
- the fix was full profile coverage tested against a reference CSMS
- heartbeat and reconnection behavior decides control-room trust

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:
- incoming contactors, RCDs and metering ICs are batch-checked against the approved BOM before assembly starts
- CE, RoHS and IEC 61851-1 documentation ships with every commercial order
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
Here is the step-by-step path the order took, with the checkpoints that kept quality on track. 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
