WALLBOX wall-mounted charging station 22 kW type 2 Doktorvolt 9574 DV-9574-EV

Smart charging at home and at work

The WALLBOX station by Doktorvolt is a compact device for charging electric vehicles and plug-in hybrids, designed for installation on a building wall, a pole, or another load-bearing element. Unlike portable chargers, this model is permanently mounted - meaning you don't have to unpack the equipment or look for a socket every time. Simply connect the cable to the Type 2 socket and start the process with one button.

The housing, with dimensions of 255 × 205 × 112 mm, is made of high-quality plastic resistant to UV radiation. The IP54 protection rating allows for installation both in an enclosed garage and outdoors - under a carport or on a building facade. The grey-black color scheme complements modern property arrangements.

Equipment, control, and operating parameters

The device is equipped with a Type 2 socket (32A, 5-pin) compliant with the IEC 62196-2 standard - this is the current standard in Europe, fitting most electric cars available on the market. The socket does not have a mechanical lock, which means the cable can be plugged in and removed freely.

Communication with the vehicle is handled by an intelligent charging controller. While standard sockets simply deliver current, the WALLBOX actively supervises the entire process - monitoring charging parameters, checking the vehicle's readiness to receive energy, and automatically interrupting charging if an error is detected.

On the front panel, there is a backlit START/STOP button with an integrated LED diode signaling the current operating status of the device.

The maximum power is 22 kW, however, the device is flexible - it also supports lower power levels (from 3.7 kW), adapting to the capabilities of the electrical installation and the parameters of the vehicle itself. The nominal load current is 32A at a voltage of 400V AC. The station operates in Mode-3, which defines normative communication between the charging point and the vehicle - ensuring DC leakage control (RCM module) and continuous data exchange throughout the process.

Built-in protections

The manufacturer has installed two key protective elements inside the housing:

• Type A RCCB (RCD) - protects the user from electric shock in case of insulation failure,
• RCM Module - detects DC leakage (DC leak), which could interfere with the operation of a traditional RCD in the distribution board.

This is particularly important for people who are unsure about the state of the electrical installation in the building. Built-in protections reduce the risk of false trips of the upstream RCD and eliminate the need to install additional protective elements directly at the station.

Operating conditions, certificates, and applications

The operating temperature range is from −5°C to +40°C according to some manufacturer sources (other sites state −20°C to +50°C - the difference may result from different hardware versions). Regardless of which specification is used, the station is suitable for year-round use in the Polish climate.

The manufacturer recommends avoiding installation in places exposed to intense sunlight for long hours - not because of UV radiation (the housing is resistant), but due to the overheating of the internal electronics. The optimal location is a garage, a north-facing carport, or a building wall partially shielded from the sun.

The device holds certificates confirming compliance with European safety standards:

• TÜV SÜD - independent certification from the German Technical Inspection Association,
• CE - authorization for sale within the European Union,
• IEC 61439 - standard regarding low-voltage switchgear and controlgear assemblies,
• EN 62196-2 - standard specifying the dimensions and parameters of Type 2 sockets,
• ISO 9001:2015 - the manufacturer's quality management system.

The WALLBOX station is effective both in single-family homes (EV owners looking for a convenient place for overnight charging) and in commercial facilities: offices and business parks, hotels, shopping centers, public institutions, and guarded parking lots. The installation is stationary - the device is attached to a wall or pole using standard mounting accessories (the PG21 cable gland allows for the connection of the power cable).
