Executive Summary: 10-Socket Wall Charging Board for Global Buyers

The part of the story that changed the buyer's math The WL-WM10 puts 10 breaker-protected sockets on an IP54 steel panel, each metered and fused, with a firmware load group cap and per-socket auto cut-off. Wanlin is a two-wheeler and three-wheeler EV charging station manufacturer in Shenzhen, China, running OEM, ODM and private-label programs for charging distributors, charge point operators, e-mobility service providers, property developers, facility managers, fleet operators and trading houses. The numbers that mattered and the landed margin landed at 38% after freight and duties for importers who source factory-direct, with per-model CE / RoHS / IEC 61851 documentation, OCPP 1.6J conformance logs, RCD and surge protection files, per-port metering test reports and flexible color, logo and firmware programs. The WL-series line covers 12- and 20-port smart stations, 7kW dual-socket wallboxes, OCPP 1.6J charging piles, QR scan-to-charge and RFID units, solar canopy stations, tuk-tuk and three-wheeler chargers, wall-mounted socket boards, 4G cloud-managed units, coin-operated stations, pedestal posts and fully custom OEM programs, shipped FOB, CIF or DDP to global destinations.

Case Study: Kuala Lumpur Condo Management Buyer Sourcing Success

A sourcing visit that began with a spreadsheet ended with a field trial. 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, Sonesack Phommachanh selected Wanlin as their EV charging manufacturing partner. The purchasing manager signed after comparing failure modes, not just port counts and prices.

• 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
• a private label run can start from 50 units on existing tooling with new packaging

At the taxi queue stand, drivers tapped RFID cards while the station logged each session to the cloud.

Problem Analysis & Field Report: Why Global Buyers Need 10-Socket Wall Charging Board

Nobody flagged it at the packing station; the market flagged it first. A garage manager found the flat monthly charging fee lost money on the three delivery riders who charged daily.

Field case: A shop-house row in Kuala Lumpur split a tripping group breaker across the WL-WM10 capped load groups. Laundry evenings no longer cut charging, and the owner added a second board for the row delivery riders.

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:

• 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

Sourcing teams like the process because each gate has a deliverable and a date. 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

The notes below are from follow-up calls after the first containers sold through.

• Somchai Prasert (EV Charging Station Distributor, Bangkok, Thailand): "Two containers in, the fault line in our service log is still empty."
• Nguyen Hoang Minh (Charge Point Operator, Ho Chi Minh City, Vietnam): "The first article matched the approved sample on meter accuracy, finish and weight. That almost never happens."
• Sonesack Phommachanh (Condo Management Buyer, Kuala Lumpur, Malaysia): "We changed the tariff logic for our market and they turned the firmware around in a week."

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.
