Published by Wanlin Fire | Last updated: September 03, 2026 | Expertise: two-wheeler and three-wheeler EV charger OEM manufacturing for global markets
Anucha Srisuwan, an EV Charging Equipment Wholesaler in Yangon, walked into a supplier search with three hard requirements: OCPP compatibility, real certificate files and a payment method riders already use. The distributor had lost two container deals because the factory could not provide OCPP conformance statements before the payment deadline.
Once the samples finished a two-week weather test in Yangon, Anucha Srisuwan selected Wanlin Fire as their EV charging equipment manufacturing partner. Documentation decided it: CE / FCC / RoHS files and an OCPP 1.6J conformance statement arrived with the samples, ready for customs.
Field engineers in Yangon mounted the units, tested RFID cards and QR payments, and left the property team with a one-page operating checklist.
Most charging problems in growing cities are not about the vehicle, they are about the socket: wrong voltage, no protection, no payment record and no maintenance plan. A delivery firm in Yangon lost 16% of daily trips to charging downtime, because riders had to wait for a charge instead of swapping a pack in seconds.
Field case: A two-wheeler fleet in Yangon moved to a swap cabinet at the depot entrance and cut turnaround between shifts from 45 minutes to under two.
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 Myanmar actually deal with: covered parking, humid air, 220V mains and heavy daily turnover.

The EV charger OEM process starts with a short qualification call about vehicle types, voltage, site conditions and the payment methods used in your market. A standard OEM project then follows 8 steps:
Buyers who moved from trading-company sourcing to factory-direct charging equipment describe the difference in delivery dates and documentation:
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.
Key result: By working directly with manufacturer Wanlin Fire, Yangon EV Charging Equipment Wholesaler Anucha Srisuwan achieved 37% 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.
