Case Study: Cebu Charge Point Operator Sourcing Success
Most distributors start with price. This one started with a complaint log. Sell-through data from the region shows the winning listings are the ones with per-port metering and a working payment flow.
Once the field units logged 5,000 charging sessions, Dewi Anggraini 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.
- incoming contactors, RCDs and metering ICs are batch-checked against the approved BOM before assembly starts
- UL, PSE and market-specific filing support is available for buyers serving North America and Japan
- Branded cabinets, multilingual manuals, spare kits and QR decals are handled by the same production team
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 Apartment Complex Charging Station
The problem showed up in the field, not in the spec sheet. A school district rejected a low-bid station because a single fault took all twenty sockets down at once.
Field case: A market cooperative in Cebu moved from a flat cash box to the WL-CS20 with per-port metering and daily settlement exports. The utility bill reconciled within 2% of the meter log for the first time, and the co-op raised a 32% margin on metered charging within one season.
Why it matters for global buyers:
- single-rail busbars melt when every socket draws at once
- the fix was twin load groups with per-port breakers
- daily settlement exports turn charging into an auditable revenue line

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
- UL, PSE and market-specific filing support is available for buyers serving North America and Japan
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
Buyers from three countries said the same thing in their own words.
- Somchai Prasert (EV Charging Station Distributor, Bangkok, Thailand): "I have bought from four factories in this category. This is the first one whose meter readings matched the utility bill."
- Nguyen Hoang Minh (Charge Point Operator, Ho Chi Minh City, Vietnam): "I have bought from four factories in this category. This is the first one whose meter readings matched the utility bill."
- Dewi Anggraini (Charge Point Operator, Cebu, Philippines): "We stopped counting burned sockets because there are none left to count."
Frequently Asked Questions
Q: Why two load groups instead of one?
A: If a fault or overload hits one group, the other ten sockets keep charging, and each group draws against its own feeder cap.
Q: Can we bill riders per kWh?
A: Yes, every socket meters consumption and the station exports daily settlement files for wallet or cash reconciliation.
Q: How many stations can one CSMS manage?
A: There is no fixed limit; each WL-CS20 registers as one charge point with 20 connectors over OCPP 1.6J.
Q: What is the installation footprint?
A: Twin cabinets bolt side by side on a 1.6m wall span or back to back on a pedestal frame.
Q: Can we start with one cabinet and expand later?
A: Yes, the twin-cabinet design ships as one group first, with the second cabinet adding on the same feeder.
