Case Study: Phnom Penh Parking Lot Operator Buyer Sourcing Success
Most distributors start with price. This one started with a complaint log. Importers are consolidating charging SKUs with fewer factories that can document OCPP conformance and IP ratings.
Once the first 200 charging sessions reported back, Aung Kyaw Moe selected Wanlin as their EV charging manufacturing partner. The purchasing manager signed after comparing failure modes, not just port counts and prices.
- QC holds a 99.2% first-pass target, and units that fail are logged with photos for root-cause review
- The production line follows ISO9001 procedures with incoming, in-process and outgoing inspection records
- OCPP builds support buyer-specified CSMS endpoints, security profiles and custom DataTransfer messages
The buyer opened a cabinet, checked the RCD rating against the invoice, and asked for the OCPP conformance log before powering up.
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: A dormitory in Phnom Penh swapped dial timers for the WL-WM10 after residents kept resetting free windows. Firmware timers behind lock covers ended the tampering, and the operator energy bill reconciled with the socket log for the first time.
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:
- QC holds a 99.2% first-pass target, and units that fail are logged with photos for root-cause review
- The production line follows ISO9001 procedures with incoming, in-process and outgoing inspection records
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
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): "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."
- Aung Kyaw Moe (Parking Lot Operator Buyer, Phnom Penh, Cambodia): "The sample arrived with the OCPP conformance log in the box. That sounds small until you have integrated a pile without one."
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.
