OCPP FAQ

WANLIN-002 is the 2-socket wall-mounted model (max 2.2 kW total, ideal for residential bike sheds, one unit per two parking spots). WANLIN-010 is the 10-socket high-density hub (max 10 kW, 4/3/3 phase distribution, LED ring display and voice prompts) for large sheds, campuses and delivery stations. Both run OCPP 1.6J (2.0.1 compatible) over 4G Cat.1 with per···

Yes. Wanlin is a factory-direct manufacturer of OCPP smart sockets and two-wheeler charging stations. OEM/ODM services include branding, housing color, packaging, firmware configuration and CSMS integration support. MOQ is pilot-project friendly - contact us with your target market and deployment scale for a quotation.

Charging continues. Active sessions keep running under the device's local strategy and safety limits; whitelisted cards keep working via the local list. Session records and metering data are stored on-device and automatically back-filled to your CSMS when connectivity returns.

Yes. Each socket outputs AC 220V at 0-1000W adjustable (factory default 800W) with 0.5 A adjustment steps, configurable locally or remotely. The CSMS can also apply OCPP Smart Charging profiles (TxProfile per session, ChargePointMaxProfile for the site) on top of the hardware limits.

Seven protection layers: overload, over-current (4.6 A per socket), short-circuit, leakage (30 mA, response ≤0.1 s with upstream RCD), over-temperature, no-load cut-off and battery abnormality detection. WANLIN-010 adds graded protection with a 100 mA station-level RCD plus 30 mA per socket. Auto stop-on-full ends charging when current stays low for 5 min···

Yes. Users can scan the QR code (WeChat/Alipay mini-program) to pay by duration or amount, or tap a 13.56 MHz IC card / NFC phone. Offline, a 500-card local whitelist keeps card charging working. Property managers can issue cards for unified billing.

Each physical socket is an independent OCPP connector. On WANLIN-002: connectorId 1 = left socket, 2 = right socket. On WANLIN-010: connectorId 1-10 map to sockets 1-10 (1-4 on phase L1, 5-7 on L2, 8-10 on L3). connectorId 0 is the station aggregate. StatusNotification and MeterValues are reported per connector.

Yes. Set your CSMS WebSocket URL, ChargeBoxId and credentials in the device configuration (remotely changeable after first connection). The socket connects over built-in 4G Cat.1, sends BootNotification and reports each physical socket as an independent OCPP connector. Wanlin provides configuration keys, message examples and joint debugging support.

WANLIN-002 and WANLIN-010 support OCPP 1.6J (JSON over WebSocket) as the primary protocol and are compatible with OCPP 2.0.1. Supported 1.6J profiles include Core, Firmware Management, Local Authorization List Management, Reservation, Smart Charging (TxProfile, ChargePointMaxProfile) and Remote Trigger.

OCPP is the Open Charge Point Protocol, the global open standard connecting charging hardware with management platforms (CSMS). For smart sockets it means vendor-independent control: sessions, metering, remote commands and firmware updates all work with any OCPP-compliant platform, so you are never locked to one supplier's cloud.
