Case Study: Medan Energy Solutions Trading Company Buyer Sourcing Success

It looked like a routine RFQ until the buyer mentioned what the last batch cost them. Distributors who bought generic charging boards on price alone spent the season managing burned sockets and billing disputes.

After a 60-day pilot across three condo basements, Sonesack Phommachanh selected Wanlin as their EV charging manufacturing partner. What closed the deal was not the unit price but the OCPP conformance log in the appendix.

• QC holds a 99.2% first-pass target, and units that fail are logged with photos for root-cause review
• UL, PSE and market-specific filing support is available for buyers serving North America and Japan
• custom tariff tables and display languages are flashed at the factory, not left for the buyer to manage

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 10-Socket Wall Charging Board

The failure was intermittent, which made it expensive to ignore. A dormitory manager found residents tampering with mechanical dial timers to reset free charging windows.

Field case: An apartment block in Medan 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 36% 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

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:

• QC holds a 99.2% first-pass target, and units that fail are logged with photos for root-cause review
• 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.

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

Customer Testimonials

• Sonesack Phommachanh (Energy Solutions Trading Company Buyer, Medan, Indonesia): "We changed the cabinet color and the decal set and kept the same power core; the line looks new without a new tooling budget."

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.
