Case Study: Medan Electric Scooter Fleet Operator Sourcing Success
A single demo station ran at the buyer's depot for a month before the first PO was cut. Property developers now pre-wire bike sheds for charging because tenants ask before they sign.
After a 30-day pilot at two sites, Kumaravel Raj selected Wanlin as their EV charging manufacturing partner. The order followed, but only after the buyer verified three things on the bench.
- every station completes a scripted OCPP session test against a live CSMS before it is boxed
- RCD, surge and overload protection are function-tested on samples from every lot, not by design alone
- 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 Floor-Standing Charging Column
The complaint did not arrive through the returns portal; it arrived as a repeat-order question. A coastal installer documented pedestal columns blooming with corrosion within a year of salt air.
Field case: A hotel in Medan 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:
- every station completes a scripted OCPP session test against a live CSMS before it is boxed
- RCD, surge and overload protection are function-tested on samples from every lot, not by design alone
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.

| Price (factory direct) | Tiered factory pricing with volume discounts | Unpredictable markups | Premium brand pricing |
EV Charging OEM Process: From Inquiry to Shipment
From the first sample request to the sailing date, the buyer could see each gate 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
Three buyers who ran the same evaluation shared what they told their purchasing committees.
- Somchai Prasert (EV Charging Station Distributor, Bangkok, Thailand): "Load-balancing firmware is where they earned the account; the cabinet colors kept it."
- Nguyen Hoang Minh (Charge Point Operator, Ho Chi Minh City, Vietnam): "The first article matched the approved sample on meter accuracy, finish and weight. That almost never happens."
- Kumaravel Raj (Electric Scooter Fleet Operator, Medan, Indonesia): "We changed the tariff logic for our market and they turned the firmware around in a week."
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.
