Case Study: Chiang Mai 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, Lim Wei Sheng selected Wanlin as their EV charging manufacturing partner. The purchasing manager signed after comparing failure modes, not just port counts and prices.
- A 48-hour continuous-load rack cycles every station to catch relay and meter failures early
- each model folder ships with CE, RoHS and IEC 61851 certificates plus the type-test summary
- Firmware can be customized for tariff logic, load limits, display language and payment flows
The monsoon test bench sprayed the cabinet for an hour and the IP54 gaskets kept the board dry.
Problem Analysis & Field Report: Why Global Buyers Need Floor-Standing Charging Column
It started with one return and grew into a spreadsheet of them. A retail parking row lost a charging post to a slow cart, and the column cracked at the cable entry.
Field case: A hotel in Chiang Mai chose the WL-FS7 for its drive-up bay after the full-circumference LED ring read clearly from the car. Guest complaints about dead ports fell to zero because status was visible before stepping out.
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:
- A 48-hour continuous-load rack cycles every station to catch relay and meter failures early
- each model folder ships with CE, RoHS and IEC 61851 certificates plus the type-test summary
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
Three buyers who ran the same evaluation shared what they told their purchasing committees.
- Somchai Prasert (EV Charging Station Distributor, Bangkok, Thailand): "The sample arrived with the OCPP conformance log in the box. That sounds small until you have integrated a pile without one."
- Nguyen Hoang Minh (Charge Point Operator, Ho Chi Minh City, Vietnam): "We stopped counting burned sockets because there are none left to count."
- Lim Wei Sheng (Delivery Fleet Manager, Chiang Mai, Thailand): "We stopped counting burned sockets because there are none left to count."

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.
