Case Study: Cebu Municipal Project Contractor Sourcing Success
The inquiry arrived on a Tuesday; by Friday a sample was on a plane. Across the market, most charging complaints trace back to unmetered sockets, flat-rate billing and boards with no overload protection.
After a 60-day pilot across three condo basements, Viriya Chanthavong selected Wanlin as their EV charging manufacturing partner. The order followed, but only after the buyer verified three things on the bench.
- SMT lines run three shifts and every charging board gets an automated function test before enclosure
- OCPP 1.6J conformance is verified against a reference CSMS and the log travels with the shipment
- a private label run can start from 50 units on existing tooling with new packaging
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 E-Bike Fleet Charging Depot
It started with one return and grew into a spreadsheet of them. A delivery hub found 60 riders returning at once overwhelmed the shed wiring, tripping the main breaker every payday week.
Field case: A campus rental fleet in Cebu cut battery replacements by a quarter after the WL-DP20 staggered windows stopped all-night 100% charging. Fleet uptime climbed, and the operator renewed the contract without a tender.
Why it matters for global buyers:
- simultaneous plug-ins trip depot breakers without staggered windows
- the fix was per-rider metering with payroll-ready exports
- staggered charging extends rental fleet battery life

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
- OCPP 1.6J conformance is verified against a reference CSMS and the log travels with the shipment
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
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
