Case Study: Chiang Mai Delivery Fleet Manager Sourcing Success
The first message asked for a catalog. The real question surfaced two weeks later. Property developers now pre-wire bike sheds for charging because tenants ask before they sign.
Once the field units logged 5,000 charging sessions, Maria Dela Cruz selected Wanlin as their EV charging manufacturing partner. By the time the container was booked, the decision had already been validated by real riders.
- SMT lines run three shifts and every charging board gets an automated function test before enclosure
- 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
The burned-socket shelf in the maintenance room had shrunk to zero after the old boards were swapped out.
Problem Analysis & Field Report: Why Global Buyers Need Electric Rickshaw Charging Station
Nobody flagged it at the packing station; the market flagged it first. A tuk-tuk rank operator found chargers rated for scooter packs overheating when three-wheeler batteries drew full current for hours.
Field case: A rank operator in Chiang Mai moved from flat overnight fees to per-kWh metering on the WL-TK3. Drivers paid for exactly what they drew, disputes stopped, and the operator opened a second rank on the strength of the first season.
Why it matters for global buyers:
- three-wheeler packs draw full current for hours, not minutes
- the fix was multi-stage curves, heavy-duty sockets and per-socket fuses
- per-kWh metering ends flat-rate billing disputes at ranks

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
- 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
The workflow below is the same one every Wanlin OEM order follows, from sample to dock. 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
Here is what the people who actually ordered said afterward.
- 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): "Our support line used to get billing-dispute calls weekly. That queue has gone quiet."

Frequently Asked Questions
Q: What voltages does the WL-TK3 support?
A: 48V, 60V or 72V DC configurations, matched to the pack the fleet actually runs.
Q: Does it suit both lead-acid and lithium packs?
A: Yes, multi-stage curves switch by profile so both chemistries charge correctly.
Q: Why only three sockets?
A: Three-wheeler packs draw heavy current for hours; three sockets keep the feeder, fuses and cables inside their ratings.
Q: How do drivers pay?
A: Per-kWh billing through QR wallet, or a coin option for cash ranks.
Q: Is the cable fire-safe?
A: Fire-retardant cable, per-port fuses and an overheat sensor are standard.
