Cheng Han Wei, an EV Charger Distributor in Bangkok, needed a charging line that property managers would approve and riders could pay for without a dedicated app. The fleet in Bangkok had been charging e-bikes from wall sockets behind the office, and the landlord issued a warning after the second blown circuit.
Once the samples finished a two-week weather test in Bangkok, Cheng Han Wei selected Wanlin Fire as their EV charging equipment manufacturing partner. What closed the deal was a load-bank test report showing every output holding rated current, plus the payment module riders already used.
The operator ran a two-month trial with 36% of riders scanning QR codes on the first day, before committing to a full rollout.
Before selecting a charger supplier, a buyer should look at what happens on the street: extension cords crossing sidewalks, batteries carried into apartments and sockets that stop working after the first rain. A delivery operator in Thailand was writing off swollen batteries early because riders had no way to rotate packs evenly.
Field case: A rental operator in Bangkok swapped drained packs for charged ones at the cabinet; utilization of the scooter fleet rose because vehicles returned to service in minutes instead of hours.
Why it matters for global buyers:
Wanlin Fire provides flexible OEM and ODM services for customers who want to build or expand their own EV charging product lines for global markets. Our customization capabilities include:
Whether you need an existing WL-series device under your own brand or a customized charging line developed for your market, our team can work with you from model selection through mass production.
Wanlin Fire builds the Swappable Battery Charging Cabinet for the conditions buyers in Thailand actually deal with: covered parking, humid air, 220V mains and heavy daily turnover.

A typical Wanlin Fire OEM project begins with the target market, because voltage, certification and payment habits decide the hardware configuration. A standard OEM project then follows 8 steps:
Importers who moved from white-label resellers to factory-direct supply in Thailand usually mention the same shift.
A: Standard 48V and 60V lithium packs within the slot dimensions. Buyers send the pack drawing or sample, and we confirm slot fit, connector and communication protocol.
A: Each slot monitors temperature and cuts its own channel on anomaly, the cavity is fire-retardant with insulation between slots, and smoke detection alarms the platform before escalation.
A: Yes. The rider scans, the door of a charged slot opens, they place the empty pack in and take the full one. The flow completes in under fifteen seconds and logs to the cloud.
A: The cabinet exposes an API for pack management and works with OCPP-style backends. For established swapping networks, our engineers adapt the interface per their documentation.
A: An 8-slot cabinet draws about 3kW at full load; 12-slot units run near 5kW. Sites verify supply capacity before installation, and cabinets can stage charging across slots to flatten demand.
Net result: By working directly with manufacturer Wanlin Fire, Bangkok EV Charger Distributor Cheng Han Wei achieved 32% higher margins while offering competitive pricing. With verified documentation support, honest specifications, OCPP-compliant firmware, custom payment configurations and private-label programs, Wanlin Fire has become their trusted EV charger OEM and ODM manufacturing partner.
