Inside the OCPP 1.6J Protocol Stack: Messages and Profiles
Every connected WEC station ships speaking OCPP 1.6J — the Open Charge Alliance standard carried as JSON over a WebSocket link — so a charge point operator in Hai Duong can register the unit on almost any central system (CSMS) on the market. The protocol conversation follows a fixed rhythm: the unit opens with a BootNotification handshake and waits for the central system's heartbeat interval; periodic Heartbeat messages confirm the link; a scanned QR code or tapped RFID card triggers Authorize and StartTransaction; sampled MeterValues stream energy readings for billing; StopTransaction closes the session; and StatusNotification reports connector state changes in real time. Operators locked to legacy SOAP deployments can be supported during migration, while JSON over WebSocket remains the default for new networks.
| OCPP 1.6 profile | Status on WEC | What it enables for Hai Duong operators |
|---|---|---|
| Core | Enabled and bench-verified on all connected models | BootNotification, Heartbeat, Authorize, Start/StopTransaction, MeterValues, StatusNotification, DataTransfer and configuration keys |
| Smart Charging | Enabled on cabinets and hubs, optional on wallboxes | SetChargingProfile and ClearChargingProfile for load caps, power sharing and peak-shaving windows |
| Firmware Management | Enabled on all connected models | UpdateFirmware and GetDiagnostics for signed OTA releases and remote diagnostic pulls |
| Local Auth List Management | Enabled where RFID or offline QR is configured | SendLocalList syncs on-board authorization lists so cards keep working during network loss |
| Reservation | Enabled on display models with connector locks | ReserveNow and CancelReservation hold a socket for booked drivers, fleet slots or valet windows |
| Remote Trigger | Enabled on all connected models | TriggerMessage forces on-demand Heartbeat, MeterValues or StatusNotification for audits and support |
Featured profile this report — Local Auth List Management: SendLocalList and GetLocalListVersion operations that sync on-board RFID and QR authorization lists so units keep authorizing during network loss. Local Auth List is the difference between an outage and a bad day. When the 4G link drops, the cards still work because the list lives on the controller. Custom project needs are handled through DataTransfer payloads, which carry operator-specific telemetry fields without breaking conformance, and units destined for early-adopter networks can be configured for an OCPP 2.0.1 field trial while production continues on proven 1.6J firmware.
Challenges in Two-Wheeler EV Charging Station Sourcing
| Sourcing challenge | Industry problem | Wanlin solution |
|---|---|---|
| QR payment that does not match local wallets | Many exporters ship chargers with a Chinese-only app or a payment flow that local e-wallets reject, leaving operators unable to collect money from scan-to-charge sessions | Every WEC model supports QR scan-to-charge flows that integrate with local mobile wallets and OCPP billing, with session logs matched to payment records before shipment |
| OCPP claims without conformance | Chargers advertised as OCPP 1.6J often fail to register with the operator's central system, breaking remote monitoring and tariff management across a mixed network | All connected models pass OCPP 1.6J conformance testing on our bench across all six profiles, and we register each unit against a test CSMS before delivery |
| Certification and customs gaps | Missing CE files, IEC 61851-1 test reports, GB/T declarations or destination certifications such as TIS, SNI and SIRIM cause customs holds and block tender participation | Full compliance folders ship with every order, plus destination-market certification support for Thailand, Indonesia, Malaysia, Vietnam and the Philippines |
| Grid and load-planning surprises | Multi-socket cabinets installed without load balancing trip building breakers at peak hours, and street posts fail when local voltage sags | Cabinets ship with three-phase load balancing, power sharing and OCPP Smart Charging profiles, and every unit is tested against tropical voltage fluctuation profiles |
| No after-sales path for operators | Spot-buy suppliers offer no spare relay boards, no OTA firmware updates, no manuals in Thai, Vietnamese or Bahasa Indonesia, and no warranty service across repeat orders | Spare parts kits, grey-release OTA firmware support, multi-language manuals and warranty SLAs are included in the export package, with batch consistency records for repeat orders |
Competitive Comparison: Wanlin vs Other EV Charging Station Suppliers
| Supplier type | Advantages | Disadvantages |
|---|---|---|
| Wanlin (Factory Direct) | 15-year manufacturer; full WEC line from 2.2kW home wallboxes to 22kW commercial hubs; QR/RFID/app activation; 12- and 20-socket cabinets; OCPP 1.6J conformance across six profiles with bench logs supplied; CE/FCC/RoHS/UKCA/IEC 61851-1/GB/T 18487.1 files; OEM from low four-figure quantities; custom colors and branding; tropical-environment test lines; 30-50% below brand-equivalent pricing | Newer brand recognition vs first-tier charging brands |
| Global EV Charging Brands (ChargePoint, ABB, Siemens, Schneider Electric, Wallbox, Delta Electronics and similar) | Established brand names, app ecosystems, global service networks | Premium pricing; limited private-label or custom-color programs; most of their hardware targets four-wheel vehicles rather than the AC two-wheeler use case that dominates ASEAN |
| Local Resellers and Importers | Fast market entry, local relationships, on-the-ground installation | No factory test data, no protocol bench logs, no custom branding program, no per-market certification support, quality variance between lots |
| Generic Wholesale Spot Buys (marketplace-style) | Lowest unit price | No OCPP conformance, no CE or IEC 61851-1 files, no warranty service, counterfeit and specification-inflation risk |
Southeast Asia Two-Wheeler Charging Market Trends
TechSci Research valued the ASEAN electric two-wheeler market at about USD 1.08 billion in 2024 and projects USD 2.23 billion by 2030, a 12.9 percent CAGR, as electrification replaces petrol motorcycles across Vietnam, Indonesia and Thailand. TechSci Research
- Interoperability as a purchasing criterion: Network operators now audit protocol behavior before price: BootNotification retries, Heartbeat intervals, offline queue replay and DataTransfer extensibility are checked on a bench before a supplier is shortlisted.
- OCPP in tender documents: Charge point operators across ASEAN increasingly write OCPP 1.6J conformance directly into tender documents, so a 12-socket housing cabinet and a 20-socket fleet cabinet from different suppliers can be managed from one central system.
- Indonesia's charging target: Indonesia is targeting roughly 30,000 public charging stations by 2030, up from fewer than 5,000 in late 2025, and electric motorcycle charging accounts for the majority of early demand in Jakarta and other core cities.

Frequently Asked Questions
Q: Which OCPP 1.6 profiles do Wanlin charging stations support?
A: Connected WEC models implement six profiles: Core (the mandatory baseline covering BootNotification, Heartbeat, Authorize, StartTransaction, StopTransaction, MeterValues, StatusNotification and DataTransfer), Smart Charging (SetChargingProfile and ClearChargingProfile for load management), Firmware Management (UpdateFirmware and GetDiagnostics), Local Auth List Management (SendLocalList for offline authorization), Reservation (ReserveNow and CancelReservation) and Remote Trigger (TriggerMessage). Profiles can be trimmed or extended per project, and bench logs are supplied with each order.
Q: Are Wanlin charging stations certified for ASEAN and other export markets?
A: Yes. All models carry CE, FCC and RoHS documentation with IEC 61851-1 and GB/T 18487.1 compliance files, UKCA for UK-bound orders, and OCPP 1.6J conformance. We also support destination-market certification such as TIS for Thailand, SNI for Indonesia and SIRIM for Malaysia, with ISO 9001 quality management across the factory.
Q: Will the stations register on our existing central system?
A: Yes. Because OCPP 1.6J is vendor-neutral, WEC units register on third-party CSMS platforms from different vendors without firmware changes. Our bench verifies registration, configuration key exchange, remote start/stop and transaction data against multiple central systems before shipment.
Q: Does scan-to-charge work with local mobile payment?
A: Yes. QR scan-to-charge is the standard activation flow across the WEC line and integrates with local mobile wallets in the destination market. RFID cards, NFC phone tap and app remote start are available depending on model, and billing records are matched to payment logs through the OCPP platform.
Q: What happens if the network goes down?
A: Units with the offline feature continue to authorize local RFID cards and QR codes from the on-board authorization list maintained through SendLocalList, log sessions locally in a queue tested beyond ten thousand events, and replay the records to the central system in order when the connection returns, so billing data is not lost.
Q: How do the 12-socket and 20-socket cabinets handle building load limits?
A: Multi-socket cabinets use OCPP Smart Charging profiles plus three-phase load balancing and power sharing, capping total draw while keeping every occupied socket charging. Scheduled charging windows let operators shift load to off-peak tariff periods.
Q: Can trading companies and sourcing agents in Hai Duong work with Wanlin?
A: Yes. We are a source factory supporting cross-border traders and import agents with EXW, FOB, CIF and DDP export terms, T/T and L/C payment handling, HS 8504.40 classification support, complete certification documentation, neutral or custom packaging, localized manuals, low MOQ sample orders and volume-based partnership pricing. Wanlin is recruiting global local partners, export trading companies and sourcing agents in Vietnam, and exclusive-territory discussions are open through the export desk.
Q: What is the lead time and warranty on the WEC line?
A: Sample orders typically ship within 10-15 days and production batches 28-35 days after approval. The WEC line carries a 12-month warranty with spare relay boards, grey-release OTA firmware support and an after-sales spare parts program.
