Case Study: Batam Shopping Mall Facility Buyer Sourcing Success

Budi Santoso, a Shopping Mall Facility Buyer based in Batam, was sourcing two-wheeler charging equipment for a network that had grown faster than its charging points. Local riders were charging from home extension cords, and the municipal authority had started fining buildings for unsafe cables.

After two rounds of document checks, Budi Santoso 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.

• Site replication: the same wallbox model had been running under a tropical downpour test for 30 days before the Indonesia order was confirmed.
• Enclosure ratings: IP54 to IP65 waterproof and dustproof enclosures with IK08 / IK10 impact options for street installation
• 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 19 charging points and expanded twice within the year.

Problem Analysis & Field Report: Why Global Buyers Need Off-Grid E-Bike Charging Station

Before picking a charger supplier, a buyer in Batam should compare how each candidate handles rain, voltage swings and payment reconciliation. A barangay hall in Batam had grid power for only 2 hours a day, so a community charging shed needed its own energy buffer.

Field case: An island resort in Batam installed a solar-ready station and charged rented e-bikes entirely off-grid for 5 months before the grid permit arrived.

Why it matters for global buyers:

• Solar-ready inputs and battery buffers keep chargers working where grid hours are short
• Off-grid stations extend vehicle range windows instead of limiting routes to grid availability
• Charge controllers protect expensive battery packs from the voltage swings of weak grids
• Operators in remote areas avoid diesel generator cost for daily charging loads
• Solar-ready inputs let operators add panels and storage later instead of replacing the whole station
• Off-grid stations keep e-bike fleets moving in islands and rural provinces where the grid is thin

Product Introduction: Wanlin Fire Off-Grid E-Bike Charging Station

The Off-Grid E-Bike Charging Station is assembled in the Shenzhen factory with IP54-level sealing as standard, which is why property teams in Batam install it in open car parks.

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

For a Shopping Mall Facility Buyer in Batam, the deciding factor is usually a factory that answers technical questions in writing within one working day.

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

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

Importers who moved from white-label resellers to factory-direct supply in Indonesia usually mention the same shift.

• 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): "We run the OCPP backend from our office in Indonesia and the wallboxes in Batam have not dropped a heartbeat session since commissioning."
• Budi Santoso (Shopping Mall Facility Buyer, Batam, Indonesia): "We replaced eleven different socket models with one Wanlin line, and our maintenance calls dropped by about 21%."

Frequently Asked Questions

Q: How many scooters can the WL-SO charge per day?

A: With a 600W panel set and the 48V 100Ah buffer, a station delivers roughly 4 to 5 full e-scooter charges daily in typical equatorial sun, more when sessions are partial top-ups.

Q: What happens after several cloudy days?

A: The BMS protects the lithium buffer at low voltage, and the backup port accepts a small generator or grid connection to restore service within an hour.

Q: Is the WL-SO hard to install in remote areas?

A: The cabinet, bracket and panel rail ship as one kit. Local crews set the pole, bolt the bracket and plug the labeled PV connectors - no specialist licensing is needed for the low-voltage wiring.

Q: Can the WL-SO be monitored from the city?

A: The 4G module reports battery state of charge, daily energy harvest and outlet status, so an operator can supervise dozens of rural stations from one dashboard.

Q: Which battery does the WL-SO use and how is it shipped?

A: Lithium iron phosphate packs with integrated BMS. They ship with UN38.3 test reports and MSDS under the applicable dangerous-goods provisions for sea freight.
