Case Study: Chonburi Ride-Hailing E-Bike Fleet Buyer Sourcing Success
Raj Kumar Pillai, a Ride-Hailing E-Bike Fleet Buyer in Chonburi, started with a single pilot site and needed a supplier that could scale from 10 sockets to 300 without changing platform. A monsoon-season inspection in Chonburi found rusted pins on three outdoor sockets that had never been rated for rain.
After reviewing quotes from three countries, Raj Kumar Pillai 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.
- In-house testing: every output is soak-tested at rated current, with overcurrent and overvoltage protection verified per unit
- Certification transparency: CE / FCC / RoHS / UKCA documentation is provided for applicable models, with IEC 61851 aligned design
- Local language firmware: Thai, Vietnamese, Bahasa Indonesia and Khmer button prompts and error screens are part of the ODM option.
The operator ran a two-month trial with 27% of riders scanning QR codes on the first day, before committing to a full rollout.
Problem Analysis & Field Report: Why Global Buyers Need Fleet Depot Charging Hub
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 company in Chonburi had 19 bikes and a depot with no organized charging; riders charged wherever they found a socket, and battery warranty claims were rising.
Field case: A delivery hub in Chonburi consolidated scattered chargers into a numbered bay row with a master breaker; morning dispatch now leaves with every pack topped.
Why it matters for global buyers:
- A structured depot hub centralizes charging under supervision instead of scattering it across informal sockets
- OCPP charge profiles shift depot load to off-peak tariffs automatically
- Session logs give fleet managers per-vehicle energy data for maintenance and cost allocation
- Standardized connectors and cabinets reduce battery damage from mismatched adapters
- Hub layouts group chargers, breakers and cabling into one serviceable zone instead of daisy-chained adapters
- Per-bay labelling and session logs let depot managers see which bikes actually charged overnight

Product Introduction: Wanlin Fire Fleet Depot Charging Hub
Wanlin Fire builds the Fleet Depot Charging Hub for the conditions buyers in Thailand actually deal with: covered parking, humid air, 220V mains and heavy daily turnover.

EV Charger OEM Process: From Inquiry to Shipment
The OEM process for a Thailand 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
Operators who standardized on one OCPP-compatible line report shorter vendor lists and fewer site visits:
- Andre Silva (EV Charger Distributor, Sao Paulo, Brazil): "The factory's engineer answered our voltage question in plain language on the same day, and that settled the sourcing decision."
- Priya Nair (E-Rickshaw Fleet Owner, Mumbai, India): "The load test report matched what we measured on site, and that has not happened with the previous two suppliers."
- Raj Kumar Pillai (Ride-Hailing E-Bike Fleet Buyer, Chonburi, Thailand): "Riders scan the QR code and pay with the wallet they already use; we stopped explaining how to charge."
Frequently Asked Questions
Q: How does the WL-FD manage total depot power?
A: The hub meters every outlet and follows an allocation profile. When total demand approaches the depot supply limit, lower-priority rows slow down instead of tripping the main breaker.
Q: Can riders be billed individually on the WL-FD?
A: Yes. Each RFID card maps to a rider account, and the CSMS exports per-rider energy totals for payroll deduction or recharge-card settlement.
Q: What fire safety measures does the WL-FD include?
A: Cabinet and trunking sensors watch temperature, and any outlet exceeding the threshold is cut off with an alarm pushed to the dashboard - a single fault never takes down the row.
Q: How are WL-FD hubs installed?
A: Wall frames carry rack rows of outlets with top-mounted trunking. A 30-outlet depot typically installs in one day with two electricians, and the commissioning checklist ships with the kit.
Q: Does the WL-FD work with our existing fleet software?
A: OCPP 1.6J connects to standard fleet and CSMS platforms. For custom APIs, our engineers review the interface document and confirm feasibility before the order.
