Case Study: Bandung Property Developer Sourcing Success

It looked like a routine RFQ until the buyer mentioned what the last batch cost them. The quiet shift in the category is buyers moving from flat-rate power strips to metered, OCPP-connected stations.

The pilot ran for two full months of monsoon weather, Chhay Sophal selected Wanlin as their EV charging manufacturing partner. By the time the container was booked, the decision had already been validated by real riders.

• Enclosure gaskets are spray-rig tested to verify IP54 sealing on samples from every lot
• Per-port metering accuracy is verified against a class-1 reference meter, not marketing estimates
• Custom color runs as low as 50 units on existing tooling keep first launches affordable

The bike shed had a row of scorched sockets and a handwritten notice telling riders to bring their own timers.

Problem Analysis & Field Report: Why Global Buyers Need OCPP 1.6J Compliant Charging Pile

The failure was intermittent, which made it expensive to ignore. A utility pilot rejected a charging brand because heartbeat timeouts made 30% of its piles appear offline in the control room.

Field case: An e-mobility startup in Bandung shipped the WL-OP16 after its previous supplier implemented only half the core profile and broke remote start for riders. Full profile coverage plus signed firmware won the startup its first municipal contract.

Why it matters for global buyers:

• OCPP claims without conformance logs stall utility tenders
• the fix was full profile coverage tested against a reference CSMS
• heartbeat and reconnection behavior decides control-room trust

Application Scenarios for Global Market

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:

• Enclosure gaskets are spray-rig tested to verify IP54 sealing on samples from every lot
• 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

Ranked on what caused the previous supplier to lose the account, the factory scored first on every row that mattered.

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:

1. 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
2. Select a Model Line - our team recommends WL-series platforms for your channel and price band, or works from a reference unit you send
3. Verify Documentation - request certificate files, OCPP conformance logs and test reports for the exact model before you commit
4. Confirm Customization - cabinet colors, logo, firmware behavior, tariff logic, payment flows and packaging
5. Sample Evaluation - verify meter accuracy, load balancing and CSMS integration on real samples before scaling
6. Confirm Production - after specifications, commercial terms and OEM details are locked
7. Quality Inspection - lot samples are tested and every finished station passes hipot, trip-time and burn-in racks before packing
8. Shipment - cartons leave FOB, CIF or DDP according to the agreed logistics terms
