Case Study: Da Nang Trading Company Sourcing Manager Sourcing Success
Chanrithy Meas, a Trading Company Sourcing Manager based in Da Nang, was rebuilding a charging rollout after an earlier batch of non-standard sockets failed inspection. Delivery riders were swapping batteries on the street, and two logistics firms had asked the operator to host a shared charging hub.
After reviewing quotes from three countries, Chanrithy Meas selected Wanlin Fire as their EV charging equipment manufacturing partner. A factory video walkthrough of the SMT line and aging racks removed the last hesitation about volume capacity.
- Factory proof: Wanlin Fire showed the Da Nang buyer a live OCPP 1.6J session log from an identical unit still running in Shenzhen before the container shipped.
- Enclosure ratings: IP54 to IP65 waterproof and dustproof enclosures with IK08 / IK10 impact options for street installation
- Firmware adaptation: OCPP parameters, power limits and time-based profiles configured before shipment
The first container shipped 20 days after order confirmation, and the second order was placed before the first one arrived.
Problem Analysis & Field Report: Why Global Buyers Need Battery Swapping Cabinet
The real cost of cheap charging equipment shows up after installation: melted sockets, rejected containers and riders who stop trusting the network. A delivery operator in Vietnam was writing off swollen batteries early because riders had no way to rotate packs evenly.
Field case: A food delivery fleet in Da Nang placed swapping cabinets at 26 hotspots; swap time dropped below 35 minutes and trip completion rose 31% in the pilot month.
Why it matters for global buyers:
- Swapping removes charging downtime from the rider's day entirely
- Cabinets charge packs slowly and safely, extending pack life versus fast top-ups
- Centralized pack charging keeps lithium cells out of apartments and shops
- Cabinet telemetry tracks pack health, cycle counts and replacement timing
- Swapping turns a long charge wait into a quick pack exchange at the busiest hours
- Cabinet slots log pack IDs, which helps operators rotate cells evenly and extend battery life

EV Charger OEM Process: From Inquiry to Shipment
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:
- Tell Us Your Target Market - Southeast Asia, South Asia, Africa, Latin America, Middle East or Europe; different markets may require different voltage, certification and payment configurations
- Select a Model Line - our team recommends suitable WL-series models according to your vehicle types (48V / 60V / 72V), site conditions and target customers
- Verify Documentation - for certified models, request and verify the relevant certificate, OCPP conformance and enclosure rating documentation files
- Confirm OEM Requirements - color, logo, payment modules, voltage, socket count, packaging and accessories
- Sample Evaluation - samples can be evaluated before mass production according to the agreed commercial terms
- Confirm Production - after specifications, commercial terms and OEM details are confirmed, the project can proceed to production
- Quality Inspection - chargers are inspected and tested with load-bank and aging procedures according to applicable production and quality-control standards
- Shipment - products are prepared for shipment FOB, CIF or DDP according to the agreed logistics requirements
Customer Testimonials
Buyers who moved from trading-company sourcing to factory-direct charging equipment describe the difference in delivery dates and documentation:
- Andre Silva (EV Charger Distributor, Sao Paulo, Brazil): "The OCPP conformance statement arrived with the samples, which is what our customs broker asked for on the last shipment."
- Priya Nair (E-Rickshaw Fleet Owner, Mumbai, India): "We run the OCPP backend from our office in Vietnam and the wallboxes in Da Nang have not dropped a heartbeat session since commissioning."
- Chanrithy Meas (Trading Company Sourcing Manager, Da Nang, Vietnam): "The factory's engineer answered our voltage question in plain language on the same day, and that settled the sourcing decision."
Frequently Asked Questions
Q: Which battery packs fit the WL-BS?
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.
Q: How does the WL-BS prevent charging fires?
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.
Q: Can riders swap without an attendant?
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.
Q: Does the WL-BS integrate with swapping platforms?
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.
Q: What power supply does a WL-BS site need?
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.
