Case Study: Doha Charging Infrastructure Wholesaler Sourcing Success
Peter Sanderson, a Charging Infrastructure Wholesaler based in Doha, 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.
Once the pilot site data came back, Peter Sanderson selected Wanlin Fire as their EV charging equipment manufacturing partner. The decision came down to OCPP conformance, real certificate files and a factory that would modify the socket count without redesigning the board.
- Source factory: Wanlin Fire runs in-house SMT lines, enclosure assembly and load-bank aging racks for two-wheeler and three-wheeler chargers
- 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
A 60-socket pilot was installed in two condominium basements, and occupancy of the charging bay crossed 19% within three weeks.
Problem Analysis & Field Report: Why Global Buyers Need Twin-Socket Charging Station for E-Bikes
A charging point looks simple until it has to survive humidity, voltage dips, careless riders and an inspector with a checklist. A shopping mall in Doha had 19% of its delivery scooter traffic concentrated in one loading bay, where riders fought over a single charging outlet during lunch peaks.
Field case: A mall in Doha placed two floor-standing piles at the loading dock; queue time dropped from 40 minutes to under 37 minutes because two vehicles charged simultaneously on separate circuits.
Why it matters for global buyers:
- Two independent sockets double site throughput without doubling installation work
- Floor-standing design needs no wall drilling, so rented or heritage sites can install without structural approval
- Per-socket breakers and leakage protection isolate faults instead of killing the whole site
- Session timers prevent overnight overstay and free the socket for the next rider

EV Charger OEM Process: From Inquiry to Shipment
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:
- 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 load test report matched what we measured on site, and that has not happened with the previous two suppliers."
- Priya Nair (E-Rickshaw Fleet Owner, Mumbai, India): "Spare mainboards arrived within three weeks when a storm surge damaged two sites, which kept the network online."
- Peter Sanderson (Charging Infrastructure Wholesaler, Doha, Qatar): "Spare mainboards arrived within three weeks when a storm surge damaged two sites, which kept the network online."
Frequently Asked Questions
Q: What foundation does the WL-FS need?
A: A level concrete pad with four anchor bolts is enough. The base plate template and bolt specification sheet ship with the cabinet, and two workers can complete an installation in under two hours.
Q: Can the WL-FS charge three-wheeled vehicles?
A: Yes. With the 72V socket option and a 3kW channel, the pile covers e-rickshaws and cargo tricycles. Connector type is confirmed at the specification stage before production.
Q: How does the WL-FS share power between the two sockets?
A: Each channel runs independently at its rated power. On the shared-input configuration, dynamic allocation keeps the total draw inside the supply limit without tripping the breaker.
Q: What is the lead time for WL-FS orders?
A: Standard models ship in 15 to 25 days. Custom-branded piles with special connectors need about 35 days including the sample round.
Q: Can we put our own brand on the WL-FS?
A: Yes. Logo printing, custom colors and retail-grade finish are available from 100 units, with artwork files checked by our engineers before printing.
