Case Study: Bangkok Electric Scooter Fleet Operator Sourcing Success
The buyer had already shortlisted three factories before this conversation started. Property developers now pre-wire bike sheds for charging because tenants ask before they sign.
The evaluation stretched over three weekends, Lim Wei Sheng 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.
- Every finished station is hipot-tested, RCD trip-time verified and powered through a full-port burn-in before packing
- OCPP 1.6J conformance is verified against a reference CSMS and the log travels with the shipment
- Branded cabinets, multilingual manuals, spare kits and QR decals are handled by the same production team
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 Floor-Standing Charging Column
Nobody flagged it at the packing station; the market flagged it first. A coastal installer documented pedestal columns blooming with corrosion within a year of salt air.
Field case: A coastal installer in Bangkok standardized on the WL-FS7 after salt air ate two rival columns within a year. Marine-grade coating and sealed cable entries passed the second-year inspection untouched, and the installer specified the model for all waterfront work.
Why it matters for global buyers:
- pedestals live in the impact zone of vans and carts
- the fix was aluminum columns with bollard guards and sealed entries
- status must be readable from the driver seat, not up close

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 finished station is hipot-tested, RCD trip-time verified and powered through a full-port burn-in before packing
- 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
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
Customer Testimonials
Different markets, same conclusion, in the words of the buyers themselves.

Frequently Asked Questions
Q: Why aluminum instead of plastic?
A: Pedestals live in the impact zone of vans and carts; the aluminum column with a bollard guard survives hits that crack plastic shells.
Q: Can it read status from a distance?
A: The full-circumference LED ring shows port state from the vehicle, so nobody walks to a dead port.
Q: How is the cable routed?
A: Through a trench entry in the bolt-down base, keeping the column sealed to IP54.
Q: Does one post serve two vehicles?
A: Yes, two metered sockets with independent authorization and billing.
Q: Can it stand coastal air?
A: Marine-grade coating and sealed entries carry the warranty in salt-air locations.
