Case Study: Bangkok Facility Management Company Buyer Sourcing Success
The inquiry arrived on a Tuesday; by Friday a sample was on a plane. Two-wheeler registrations climb across the region every quarter, but the charging hardware under bike sheds has barely changed in a decade.
After the operator's own four-week load-balance logging test, Nguyen Hoang Minh selected Wanlin as their EV charging manufacturing partner. The purchasing manager signed after comparing failure modes, not just port counts and prices.
- incoming contactors, RCDs and metering ICs are batch-checked against the approved BOM before assembly starts
- Per-port metering accuracy is verified against a class-1 reference meter, not marketing estimates
- Branded cabinets, multilingual manuals, spare kits and QR decals are handled by the same production team
In the back office, the CSMS dashboard showed all 20 ports online with live meter values, three days after installation.
Problem Analysis & Field Report: Why Global Buyers Need Coin-Operated Charging Station
The failure was intermittent, which made it expensive to ignore. A roadside stand owner documented jammed coin slots after the rainy season, with no way to refund stranded riders.
Field case: A market operator in Bangkok replaced a mechanical slot board with the WL-CN6 after string tricks ran months of free charging. The anti-string acceptor and per-kWh mapping ended the losses, and the operator held a 30% margin on the first season of honest coin revenue.
Why it matters for global buyers:
- mechanical slots lose revenue to strings, jams and prying
- the fix was anti-string acceptors with dual-lock cash boxes
- coin-to-kWh mapping must be adjustable in the field

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
- Per-port metering accuracy is verified against a class-1 reference meter, not marketing estimates
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.
Why Choose Wanlin as Your EV Charging OEM Manufacturer

EV Charging OEM Process: From Inquiry to Shipment
The workflow below is the same one every Wanlin OEM order follows, from sample to dock. 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
The notes below are from follow-up calls after the first containers sold through.
- Somchai Prasert (EV Charging Station Distributor, Bangkok, Thailand): "The first 60 stations sold out in a month and the repeat order came before the first container cleared customs."
- Nguyen Hoang Minh (Charge Point Operator, Ho Chi Minh City, Vietnam): "The station we field-tested through the rainy season is the station we sell; our listing says IP54 and the field record proves it."
- Nguyen Hoang Minh (Facility Management Company Buyer, Bangkok, Thailand): "I have bought from four factories in this category. This is the first one whose meter readings matched the utility bill."
Frequently Asked Questions
Q: How does the WL-CN6 stop coin tricks?
A: The acceptor uses anti-string mechanics plus a tamper log, and the cash box sits behind dual locks in an anti-pry cabinet.
Q: Can we change the coin-to-kWh rate ourselves?
A: Yes, the mapping adjusts in the field without a technician visit, so utility rate changes do not eat the margin.
Q: What happens if a socket faults after coins are inserted?
A: The station refunds automatically before charging starts when a port reports a fault.
Q: Which coins does it accept?
A: Single-coin and multi-coin acceptors are configured to the local currency at order time.
Q: Does it need a network connection?
A: No, coin operation runs fully standalone with local counters and a tamper log.
