Case Study: Medan Delivery Fleet Electrification Manager Sourcing Success

Sok Dara, a Delivery Fleet Electrification Manager in Medan, needed a charging line that property managers would approve and riders could pay for without a dedicated app. A monsoon-season inspection in Medan found rusted pins on three outdoor sockets that had never been rated for rain.

After checking three factories against the Indonesia import rules, Sok Dara selected Wanlin Fire as their EV charging equipment manufacturing partner. What closed the deal was a load-bank test report showing every output holding rated current, plus the payment module riders already used.

• In-house testing: every output is soak-tested at rated current, with overcurrent and overvoltage protection verified per unit
• Enclosure ratings: IP54 to IP65 waterproof and dustproof enclosures with IK08 / IK10 impact options for street installation
• OEM / ODM depth: custom enclosure colors, logo silk-screening, voltage ranges (48V / 60V / 72V) and socket counts

The first container shipped 23 days after order confirmation, and the second order was placed before the first one arrived.

Problem Analysis & Field Report: Why Global Buyers Need App Payment Timer Charger for E-Bikes

Field reports from fleets show the same pattern: equipment fails where the installation plan ignored protection, grounding and payment management. A night market in Medan had stall holders and delivery riders sharing two sockets, with no way to stop one person hogging the bay all evening.

Field case: A hostel in Medan set timer-based pricing on its charger; the front desk stopped policing sockets, and the nightly dispute queue disappeared.

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 App Payment Timer Charger for E-Bikes

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.

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

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:

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

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.
