Published by Wanlin Fire | Last updated: September 03, 2026 | Expertise: two-wheeler and three-wheeler EV charger OEM manufacturing for global markets
What started as a request for twenty wall-mounted units from an EV Charging Equipment Wholesaler in Hanoi became a 200-unit pilot after the first OCPP test session. The distributor had lost two container deals because the factory could not provide OCPP conformance statements before the payment deadline.
After two rounds of document checks, Anucha Srisuwan selected Wanlin Fire as their EV charging equipment manufacturing partner. The committee in Hanoi ranked the bids on OCPP conformance, spare part lead time and local voltage tolerance, not on sticker price.
Samples with the buyer logo were approved in 26 days, and mass production used the same components as the approved units.
The real cost of cheap charging equipment shows up after installation: melted sockets, rejected containers and riders who stop trusting the network. A logistics hub in Hanoi handled 60 electric motorcycles per shift with 20% of them needing a charge before the next dispatch, but the depot had only four domestic sockets.
Field case: A courier hub in Hanoi installed dual-gun commercial chargers with load balancing; the depot charged 30 bikes per night without upgrading the incoming supply.
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.
The Dual-Gun Commercial Charger is assembled in the Shenzhen factory with IP54-level sealing as standard, which is why property teams in Hanoi install it in open car parks.

The OEM process for a Vietnam importer starts with a voltage and payment survey, then moves to samples, container QC and OCPP backend onboarding. A standard OEM project then follows 8 steps:
Operators who standardized on one OCPP-compatible line report shorter vendor lists and fewer site visits:
A: On the two-phase 380V input, yes - each gun delivers its rated output. On a single-phase supply, the dynamic load balancer splits available power instead of tripping the main breaker.
A: The cabinet has a sealed bay for standard POS terminals, and the firmware exposes a payment interface for local acquirers. QR code and RFID work out of the box.
A: Hardware is 2.0.1-ready. Current production firmware runs OCPP 1.6J for the widest backend compatibility, and the 2.0.1 stack can be loaded per project once the target CSMS is confirmed.
A: Quarterly visual checks, an annual tightening inspection and filter cleaning. The cabinet reports fan and temperature status over OCPP so servicing can be scheduled before failures.
A: Standard builds ship in 25 to 35 days. Configured units with POS integration or special gun cables run 40 to 50 days including sandbox testing against the buyer backend.
Net result: By working directly with manufacturer Wanlin Fire, Hanoi EV Charging Equipment Wholesaler Anucha Srisuwan achieved 35% 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.
