A modern 22kW charger for semi-public and home use is the ideal solution for powering electric vehicles in company parking lots, residential community parking spaces, and private garages. The Defenzo Wallbox AC22 Pro Smart model, with a rated power of 22 kW, combines exceptional alternating current (AC) efficiency, advanced authorization systems, and full integration with smart home systems. It was created for locations where the device must operate reliably, quickly, and under the full control of the manager or owner.
Quick connection and modern design with LCD screen
The Defenzo Wallbox Pro Smart AC22 stands out with its elegant black housing, modern look, and dimensions of 250 × 250 × 90 mm. A key element of the front panel is the color LCD display, which presents the most important charging parameters in real-time, such as:
- current amperage,
- mains voltage,
- duration of the current session,
- current energy consumption.
Additionally, the current operating status of the device is signaled by colored LED backlighting around the screen and the illuminated Defenzo logo.
The device is designed for simple implementation into existing three-phase infrastructure (operating voltage 3 phases; 380-440V, frequency 50/60Hz, input current 32A). The wallbox features a red CEE power plug, which allows for quick connection to the installation without the need for complicated assembly work. Power transmission to the vehicle is provided by an integrated 5-meter cable terminated with a universal TYPE 2 (IEC 62196) female connector.
Safety and access control in shared spaces
When a 22kW charger for semi-public use operates in a publicly accessible area, protecting it against unauthorized power consumption becomes crucial. Defenzo Wallbox AC Pro Smart solves this problem through two integrated authorization methods: session initiation can be done via a mobile app or through the built-in RFID reader, which allows access to charging only to selected users who possess a card.
Managing operating parameters is also facilitated by the charging delay function and a physical current intensity change button located directly on the device housing. The construction features an IP54 protection class, ensuring full resistance to mechanical damage and moisture. This allows for the installation of the wallbox in demanding environments – from underground multi-space garages to open outdoor parking lots. The device operates reliably at temperatures from -30°C to 50°C and at relative humidity from 5% to 95% (non-condensing), even at altitudes up to 2000 meters above sea level.
Smart Home features and mobile application
Both in home and commercial applications, a huge advantage of the device is the free Defenzo mobile application (available in the App Store and Google Play for Android / iOS systems). The device works with popular platforms like Tuya Smart and Smart Life, which allows for easy integration with the smart home ecosystem, including Google Home and Amazon Alexa systems.
The mobile application gives full control over the vehicle charging process and allows for:
- Charging control: remote start and stop, selection of startup mode (automatic upon connection, manual via app, or unlocking with an RFID card), and adjustment of charging current (amperage) directly from the phone.
- Charging schedule: setting exact start and end times for sessions, defining the target battery charge level, and limiting the maximum session time (an ideal solution for cost optimization and charging during cheaper night tariffs).
- Monitoring and safety: constant insight into session history, preview of currently available power, current charger temperature indicator, and access to the history of saved errors and warnings.
Multi-level electrical protection system
Working with such high rated power requires uncompromising protection of the electrical installation. This advanced station from Defenzo has extensive circuits protecting the device, the installation, and the user.
The basis of protection is the built-in RCD Type B residual current circuit breaker (30mA AC + 6mA DC) with a residual current detection module, which effectively protects against AC and DC leakage currents. The device’s electronics monitor the network in real-time, protecting against overvoltage (protection value is 465V) and voltage drops below the standard (limit value 330V).
The system also reacts immediately to overload (when parameters reach or exceed 110%) and overheating – the charging process is automatically interrupted when the internal temperature reaches 85°C. Furthermore, in the event of detecting a lack of or irregularities in grounding or improper power frequency (50/60Hz), charging is automatically blocked, guaranteeing the highest level of reliability confirmed by a 2-year manufacturer’s warranty.
Choose a proven 22kW charger for semi-public use
The Defenzo Wallbox AC22 Pro Smart is a universal and versatile charging station. Thanks to advanced RFID authorization functions, full integration with Tuya and Smart Life apps, and high 22 kW power, it is an excellent choice for companies, residential communities, and demanding home users looking for reliable equipment for years to come.
