A sourcing visit that began with a spreadsheet ended with a field trial. Property developers now pre-wire bike sheds for charging because tenants ask before they sign.
The evaluation stretched over three weekends, Noppadol Wichaidit selected Wanlin as their EV charging manufacturing partner. By the time the container was booked, the decision had already been validated by real riders.
In the back office, the CSMS dashboard showed all 20 ports online with live meter values, three days after installation.
What looked like a price problem turned out to be a reliability problem in disguise. A street-site operator found riders abandoning sessions when the QR payment page took longer than ten seconds on the local network.
Field case: A street-site operator in Surabaya switched to the WL-QR10 after gateway outages froze every port on the old station. Cached tariff rules and offline session logs kept riders charging through two outages in the first month, and settlement reconciled to the cent afterward, protecting a 36% margin that used to leak through refunds.
Why it matters for global buyers:
Wanlin runs OEM and ODM programs for buyers who want their own charging station line without building a factory. Customization covers:
Inside, the board layout keeps the 4G radio away from the contactor coil so sessions stay online when ports switch.

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:
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.
The rows below come from the buyer's own comparison notes, not from our brochure.
| Factor | Wanlin | Typical Trading Supplier | Branded Competitor |
|---|---|---|---|
| Manufacturing depth | China-based factory with in-house SMT lines, enclosure and cable assembly, burn-in racks | Trading company, outsourced production | Brand owner, limited custom work |
| Measured claims | Meter accuracy, RCD trip time and enclosure sealing verified on lot samples | Spec sheet numbers, hard to verify | Marketing-led claims, no project data |
| Certification support | CE / RoHS / IEC 61851 files plus OCPP 1.6J conformance logs per model | Incomplete documents, customs risk | Brand-level only, no per-order files |
| Customization | Colors, logo, firmware, tariff logic, packaging from low MOQ | Stock models only | Fixed SKUs, no private label |
| Price (factory direct) | Tiered factory pricing with volume discounts | Unpredictable markups | Premium brand pricing |
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:
Three buyers who ran the same evaluation shared what they told their purchasing committees.
A: Median time runs under six seconds on local networks, with the socket locking at scan to hold the port.
A: Cached tariff rules let ports keep charging, and offline sessions reconcile automatically when the gateway returns.
A: Yes, UV-laminated tamper-proof decals are rated for a full outdoor season and reprint kits ship with spares.
A: Yes, both modes run at the same time on different port groups, with time-of-day tiers.
A: The LCD tariff board lists current rates for every port mode.
What the field test actually measured By working directly with manufacturer Wanlin, the Delivery Fleet Manager team in Surabaya reached 36% higher margins on its charging line while keeping rider tariffs competitive. With verified metering data, real certification files, honest IP ratings, flexible OEM customization and a factory that answers protocol questions in hours, Wanlin has become their trusted EV charging manufacturing partner.
