Main product properties

Smart EV charging station for residential charging environments

Single-phase or three-phase device

Maximum charging power

Single-phase installation: 7.4 kW (1 × 32 A; 230 V~) *

• Three-phase installation: 22 kW (3 × 32 A; 230/400 V~) *
  * The maximum charging current may be reduced by a temperature derating functionality of the charging station when an over-limit temperature inside the station is detected.

Charging outlet type

• Type 2 (IEC 62196-2)

  • socket

  • socket with shutters (IEC 62196-1)

  • tethered charging cable (available in 5 m and 7 m)

Device power consumption (depends on configuration and operating mode)

• Standby: 3–5 W

• Max: 10–15 W

User identification: None, INCH Core app, RFID

User interface: LED and sound signals, touch button, INCH Core (mobile) app (iOS, Android)

Material: Polycarbonate reinforced with glass fibers, TPE gasket

Colour: Light grey (RAL 7001)

Modularity – the charging station consists of three modules – enables simple and fast product delivery and installation:

• Module 1 – Dock (wall mount)

• Module 2 – Output socket / Output socket with shutter / Output cable (5 or 7 m)

• Module 3 – Main unit

Power cable entrance direction: from the back, bottom, or top

Setting up of the charging station, as well as upgrading the firmware (FW), can be done locally or remotely, in compliance with the predefined access levels.

Level of protection

• Impact protection: IK10 protection against external mechanical impacts to enclosure (IEC 62262)

• Ingress protection: IP56 protection against dust and liquid penetration (IEC 60529)

• Overvoltage category: OVC III, when the device is protected by up-stream SPD

• Overheating Prevention: built-in temperature derating function reduces charging power if over-limit temperatures are detected inside the charging station, limiting the maximum charging current to prevent overheating. Temperature derating functionality helps preserve intact charging station functionality and safety in extreme conditions.

Electrical protection

• Built-in

  • Software overcurrent protection: based on measuring the supplied currents and checking if they are within the permitted limits. It stops charging if the load (EV) does not follow the current setpoint and thus prevents circuit breaker outage.

  • DC fault protection in accordance with IEC 62955: based on the measurement of DC leakage current by the integrated DC leakage current sensor.

  • PEN fault protection (UK): feature based on measuring the voltage between the phase conductors and calculation of the neutral voltage.

External

• According to IEC 61851, the following protection is required to be installed externally upstream of the charging station:

  • Surge and overvoltage protection (Surge Protection Device (SPD), Type 1+2), U_p(L-PE, N-PE) < 2.5 kV; I_n > 5 kA,  

  • Overcurrent protection (MCB, I_n = 40 A, characteristic C),

  • Differential protection (RCD type A (IEC 62955), I_n = 40 A, I_Δ = 30 mA).

Communication technologies – allow communication with INCH Core System, BEMS (Building Energy Management System), cloud integration, and ensure communication stability.
