Confirm power control
Check relay, metering, safety cutoff, and charging session rules.
Charging socket control
EV charging socket payment controller for timed power sessions.
Use QuLink when charging sockets, e-bike charging cabinets, or metered power devices need QR payment, timed relay control, power/session data, and server callbacks.

Project fit
For charging and metered power equipment
Buyer signals
- E-bike charging, charging sockets, power banks, and metered power devices.
- Operators that need QR payment or app approval to start a timed session.
- Devices that need metering, stop logic, and session status upload.
- OEM projects that need a board, firmware, and enclosure path.
What to send first
- Machine photo or existing board photo
- Interface or wiring note if available
- Target action after API command or payment
- Whether telemetry or data upload is required
Integration model
Control power output from your server workflow
QuLink maps payment or API approval to relay output, timed run, stop behavior, and session data upload.
- Machine interface
- relay output, metering input, sensor input, serial/RS485 option
- Trigger source
- QR payment, app approval, wallet callback, server command
- Data returned
- session.started, session.completed, metering data, fault, online status
- Project mode
- charging retrofit, metered device rollout, OEM payment controller
Workflow
From machine interface to API-controlled result.
Map session
Define price, duration, stop behavior, and data fields.
Start charging
QuLink triggers the output after payment or API approval.
Upload session
Your server receives duration, result, and optional metering data.
API example
A clear server command or webhook for the machine-side action.
The exact command fields depend on machine interface, firmware profile, and whether payment or your own app triggers the action.

Start the project
Send the first machine details before writing a full spec.
Send the charging device photo, relay/power notes, metering requirement, session rule, and target deployment country.
Useful first message
- Machine type and target country
- Machine photo, board photo, or wiring photo
- Action after API command or payment
- Data upload and estimated quantity
FAQ
Questions buyers usually ask before a sample test.
Can QuLink handle charging safety requirements?
QuLink can handle control and data workflows, but electrical safety design must be confirmed for the specific device and market.
Can it upload metering data?
Yes, if metering data is available through supported inputs, serial, RS485, or an OEM profile.
Can it stop sessions remotely?
Yes, when the machine-side wiring supports stop or relay cutoff behavior.
