The request that opened the account was a fault report, not a purchase order. Property developers now pre-wire bike sheds for charging because tenants ask before they sign.
Once the field units logged 5,000 charging sessions, Noppadol Wichaidit selected Wanlin as their EV charging manufacturing partner. The contract went to the factory that could show RCD trip-time data and sealed enclosures, not the lowest quote.
At the taxi queue stand, drivers tapped RFID cards while the station logged each session to the cloud.
The problem showed up in the field, not in the spec sheet. A shopfront owner watched sun-faded QR decals send riders to a dead link after one hot season.
Field case: A shopfront chain in Bandung replaced sun-faded stickers with the WL-QR10 UV-laminated per-port QR decals and tamper-proof covers. Scan success stayed above 99% through the hot season, and the chain added a second station at its flagship corner.
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.
Ranked on what caused the previous supplier to lose the account, the factory scored first on every row that mattered.
| 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 |
Moving from first contact to a sealed container took a sequence the buyer could follow in writing. A standard charging station OEM project then follows 8 steps:
The quotes below come from follow-up calls after the first season of uptime data arrived.
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.
