Case Study: Batam Electric Tuk-Tuk Fleet Operator Sourcing Success

The buying team in Batam had approved a European wallbox brand when the finance director asked how warranty returns would be handled from Indonesia; that question reopened the sourcing file. Property managers across Batam were banning battery packs in lifts after a hallway fire in a nearby condo, which pushed residents toward supervised charging bays.

After comparing four shortlisted factories, Maria Santos selected Wanlin Fire as their EV charging equipment manufacturing partner. In the end the buyer chose the supplier that could ship CE and IEC 61851 documents with the first container, since customs clearance in Indonesia had stalled two earlier orders.

• Spare support: mainboards, payment modules and enclosures are kept as spares for after-sales replacement
• Document pack: certificate files, user manuals, installation guides and wiring diagrams are packed with each export order
• Payment customization: QR code with local payment gateway, RFID cards, coin acceptor or App billing configured for the target market

After a factory audit and sample evaluation, the partner placed a first order of 11 charging points and expanded twice within the year.

Problem Analysis & Field Report: Why Global Buyers Need Coin and App Payment Timer Charger

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 motorcycle shop in Indonesia offered charging as a side service but lost money because customers left bikes plugged in overnight.

Field case: A market in Batam installed coin-and-App chargers; riders without wallets used coins, tourists scanned, and utilization reached 17% across both groups in the first month.

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

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.

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.

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

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 first batch for Batam arrived with routine test reports inside every carton, which made our customs broker's job much easier."
• Priya Nair (E-Rickshaw Fleet Owner, Mumbai, India): "The factory's engineer answered our voltage question in plain language on the same day, and that settled the sourcing decision."
• Maria Santos (Electric Tuk-Tuk Fleet Operator, Batam, Indonesia): "The load test report matched what we measured on site, and that has not happened with the previous two suppliers."

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.
