Case Study: Singapore Electric Motorcycle Importer Sourcing Success
Jomar Dizon, an Electric Motorcycle Importer based in Singapore, was rebuilding a charging rollout after an earlier batch of non-standard sockets failed inspection. Electric motorcycle registrations in Singapore were climbing faster than the utility could approve new meter points, so shared charging rows became the practical answer.
After two rounds of document checks, Jomar Dizon 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.
- Site replication: the same wallbox model had been running under a tropical downpour test for 30 days before the Singapore order was confirmed.
- 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 42% of riders scanning QR codes on the first day, before committing to a full rollout.
Problem Analysis & Field Report: Why Global Buyers Need Coin-Operated Timer Charging Pile
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 street vendor market in Singapore had riders who carried no smartphone wallet and tourists who carried no local coins; one payment method excluded half the users.
Field case: A market operator in Singapore set a timer charger at a flat rate per hour; the hogging problem disappeared and the bay turned over 13 times a night.
Why it matters for global buyers:
- Dual coin and App payment covers users with and without smartphone wallets
- Timer countdowns end overstay and make socket turnover predictable
- Coin operation works during power or network outages when App payment cannot reach the server
- Session logs reconcile coin drops with App records for operators and auditors
- Timer control caps each session, so one rider cannot occupy a public bay for the whole evening
- Coin and app options suit markets where cash is still common and riders without smartphones are regulars

Product Introduction: Wanlin Fire Coin-Operated Timer Charging Pile
Each Wanlin Fire charger pairs a protected AC-DC stage with an OCPP-ready control board, so operators can manage sessions, pricing and diagnostics from one backend instead of five different Apps.

- 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

EV Charger OEM Process: From Inquiry to Shipment
The OEM process for a Singapore 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."
- Jomar Dizon (Electric Motorcycle Importer, Singapore, Singapore): "The OCPP conformance statement arrived with the samples, which is what our customs broker asked for on the last shipment."
Frequently Asked Questions
Q: Why keep coin payment on the WL-TM?
A: In many markets a large share of two-wheeler riders still pay cash. The dual-flow design keeps those riders served while the QR option captures card and wallet users.
Q: How is the coin box emptied and audited?
A: The box sits behind a security lock. The counter log records total coins per day, so the collection tally can be checked against physical coins in minutes.
Q: Can pricing differ by outlet on the WL-TM?
A: Coin pricing is set per cabinet, while app pricing can differ per outlet. Operators commonly run uniform coin pricing and time-based app tiers.
Q: What happens when the timer ends?
A: The outlet powers off and the LED goes dark, freeing the slot for the next rider. The vehicle cannot keep drawing current once the session closes.
Q: Does the WL-TM replace old resistor-panel stations?
A: Yes. It mounts on the same wall footprint and reuses the existing supply in most retrofits, which is why property managers choose it for legacy upgrades.
