Case Study: Dhaka Micromobility Charging Network Buyer Sourcing Success

Hannah Whitlock, a Micromobility Charging Network Buyer in Dhaka, walked into a supplier search with three hard requirements: OCPP compatibility, real certificate files and a payment method riders already use. Local riders were charging from home extension cords, and the municipal authority had started fining buildings for unsafe cables.

After reviewing quotes from three countries, Hannah Whitlock 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.

• Export experience: the factory ships charging equipment to Southeast Asia, South Asia, Africa, Latin America and the Middle East
• Payment compliance: QR, RFID, NFC, coin and App payment modules are selected to match local payment habits and regulations
• Firmware adaptation: OCPP parameters, power limits and time-based profiles configured before shipment

The operator ran a two-month trial with 29% of riders scanning QR codes on the first day, before committing to a full rollout.

Problem Analysis & Field Report: Why Global Buyers Need E-Rickshaw Charging Station

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 city in Dhaka introduced electric three-wheelers for school routes, but the operator could not find charging equipment that matched a 72V lithium bank with a safe charge profile.

Field case: A school transport operator in Dhaka ran a 20-rickshaw route on six 72V charging sockets; pre-trip dead batteries dropped from three per week to zero in 2 months.

Why it matters for global buyers:

• Correct voltage matching (48V / 60V / 72V) protects controllers and battery packs from overvoltage damage
• Charge profiles with CC-CV stages extend pack life compared with uncontrolled rectifiers
• Rickshaw fleets convert daytime idle time into revenue when charging is available at stands
• Metered sockets end the flat-fee fights between drivers who do different daily mileage

Product Introduction: Wanlin Fire E-Rickshaw Charging Station

Wanlin Fire builds charging stations around three things riders and operators actually measure: reliable output under load, payment methods people already use and certificate files that clear customs.

Core Features:

• China-Based Manufacturing: Wanlin Fire is based in Shenzhen, China and focuses on two-wheeler and three-wheeler EV charging equipment, with in-house SMT production, enclosure assembly and per-unit load-bank and aging tests
• Certification Transparency: Real documentation for applicable certified models - instead of simply stating a product is "certified", buyers can verify the certificate and OCPP conformance documents for the exact model they intend to purchase
• OCPP-Ready Control: chargers run OCPP 1.6J compliant firmware with 2.0.1 upgrade paths, so operators connect to their own CSMS instead of a closed vendor cloud
• Private Label Support: color, logo, payment module, voltage, packaging, manuals and firmware parameters customized according to project requirements
• Global Market Experience: we work with distributors, operators and fleet owners worldwide and understand export steps, certification questions, local payment habits, labeling preferences and tender submission needs

Application Scenarios for Global Market

Certified EV Charger Manufacturing for Global Markets

Certification is one of the most important considerations when sourcing EV charging equipment for export. Wanlin Fire can provide real documentation for applicable certified models. Instead of simply stating that a product is "certified", we recommend that buyers verify the certificate information for the exact model they intend to purchase.

For customers exporting EV chargers, Wanlin Fire supports CE, FCC, RoHS and UKCA documentation with per-model files, and for projects where additional testing applies, the relevant documentation and testing path can be arranged for any represented model before ordering. Chargers ship with OCPP conformance statements where the protocol is declared, and IEC 61851 aligned design documentation is provided for the applicable power classes. Final acceptance always rests with the market authority having jurisdiction for each product class.

Why Choose Wanlin Fire as Your EV Charger OEM Manufacturer

Wanlin Fire positions itself as the manufacturing partner behind local charging brands, offering private label, payment customization and after-sales spare parts rather than a closed hardware box.

Wanlin Fire's EV charger OEM services are suitable for: EV charger distributors, two-wheeler EV importers, e-bike brand procurement teams, e-scooter fleet operators, micromobility charging network buyers, e-rickshaw fleet owners, charging infrastructure wholesalers, property developers, delivery fleet managers, retail charger buyers, trading company sourcing managers, community charging project managers, utility partnership buyers and government mobility project officers.

EV Charger OEM Process: From Inquiry to Shipment

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:

1. 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
2. Select a Model Line - our team recommends suitable WL-series models according to your vehicle types (48V / 60V / 72V), site conditions and target customers
3. Verify Documentation - for certified models, request and verify the relevant certificate, OCPP conformance and enclosure rating documentation files
4. Confirm OEM Requirements - color, logo, payment modules, voltage, socket count, packaging and accessories
5. Sample Evaluation - samples can be evaluated before mass production according to the agreed commercial terms
6. Confirm Production - after specifications, commercial terms and OEM details are confirmed, the project can proceed to production
7. Quality Inspection - chargers are inspected and tested with load-bank and aging procedures according to applicable production and quality-control standards
8. 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): "Spare mainboards arrived within three weeks when a storm surge damaged two sites, which kept the network online."
• Priya Nair (E-Rickshaw Fleet Owner, Mumbai, India): "The OCPP conformance statement arrived with the samples, which is what our customs broker asked for on the last shipment."
• Hannah Whitlock (Micromobility Charging Network Buyer, Dhaka, Bangladesh): "We replaced eleven different socket models with one Wanlin line, and our maintenance calls dropped by about 29%."

Frequently Asked Questions

Q: Which battery voltages does the WL-3W support?

A: 48V, 60V and 72V lead-acid and lithium packs. The output voltage is fixed per unit at ordering, and dual-voltage versions are available for mixed fleets.

Q: Can the WL-3W recover a deeply discharged lead-acid rickshaw battery?

A: The pre-charge stage slowly lifts heavily discharged packs before full current flows, which is what most roadside chargers skip and why batteries die early.

Q: How does the WL-3W prevent overcharge?

A: The control board tracks the charge curve and drops to a float stage automatically. On the timer version, the session ends at the set time and the outlet powers down.

Q: Is the WL-3W safe in the rain?

A: The enclosure is IP54 and the output sockets sit under a molded drip shield, so open-air rickshaw stands can install it without extra roofing.

Q: What plug does the WL-3W use?

A: Standard fleets usually bring their own connector drawing and we match it. Common three-wheeler plug types are stocked, and custom molds run from 500 units.
