Case Study: Rayong Electric Tuk-tuk Fleet Operator Sourcing Success
The request that opened the account was a fault report, not a purchase order. Importers are consolidating charging SKUs with fewer factories that can document OCPP conformance and IP ratings.
Once the field units logged 5,000 charging sessions, Chhay Sophal 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.
- SMT lines run three shifts and every charging board gets an automated function test before enclosure
- each model folder ships with CE, RoHS and IEC 61851 certificates plus the type-test summary
- OCPP builds support buyer-specified CSMS endpoints, security profiles and custom DataTransfer messages
At the condo gate, a rider scanned the QR, watched the socket lock, and plugged in without touching an attendant.
Problem Analysis & Field Report: Why Global Buyers Need Wall-Mounted Charging Socket Board
What looked like a price problem turned out to be a reliability problem in disguise. A dormitory manager found residents tampering with mechanical dial timers to reset free charging windows.
Field case: An apartment block in Rayong fitted the WL-WM10 after swollen battery packs traced back to all-night charging on timer-less boards. Per-socket auto cut-off stopped the cooking, and the building committee recovered a 37% margin by switching the garage from flat fees to per-socket kWh billing.
Why it matters for global buyers:
- unattended overnight charging swells packs without per-socket cut-off
- the fix was firmware timers behind lock covers
- load groups stop one appliance evening from killing every socket

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:
- SMT lines run three shifts and every charging board gets an automated function test before enclosure
- 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.
Why Choose Wanlin as Your EV Charging OEM Manufacturer
The buyer compared five candidates on the metrics that caused their previous failures.
| Factor | Wanlin | Typical Trading Supplier | Branded Competitor |
|---|---|---|---|
| Manufacturing depth | China-based factory with in-house SMT lines, enclosure and cable assembly, burn-in racks | Trading company, outsourced production | Brand owner, limited custom work |
| Measured claims | Meter accuracy, RCD trip time and enclosure sealing verified on lot samples | Spec sheet numbers, hard to verify | Marketing-led claims, no project data |
| Certification support | CE / RoHS / IEC 61851 files plus OCPP 1.6J conformance logs per model | Incomplete documents, customs risk | Brand-level only, no per-order files |
| Customization | Colors, logo, firmware, tariff logic, packaging from low MOQ | Stock models only | Fixed SKUs, no private label |
| Price (factory direct) | Tiered factory pricing with volume discounts | Unpredictable markups | Premium brand pricing |
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
The quotes below come from follow-up calls after the first season of uptime data arrived.

Frequently Asked Questions
Q: How does the WL-WM10 stop overnight overcharging?
A: Each socket runs a timer with auto cut-off, so packs stop drawing at the set time or full-charge signal.
Q: Can the load cap match our building wiring?
A: Yes, the group ceiling is set in firmware to the feeder rating the building actually has.
Q: What prevents residents from resetting timers?
A: Timer settings sit behind a lockable cover; riders only see socket status and QR.
Q: Is billing per socket or per board?
A: Per socket, with QR payment and kWh logs exported for building management.
Q: Can it mount on an outdoor shed wall?
A: Yes, the IP54 panel handles shed and column mounting with the included anchor kit.
