The eFuture has already started

The world of mobility is undergoing a significant transformation due to the dynamic development of electric vehicles. Growing awareness of environmental responsibility and the promotion of sustainable energy solutions have made electric cars a permanent fixture in our society. A key component of this development is the wallbox – an indispensable device for any electric car owner and businesses with substantial on-site parking. The intelligent wallbox, which has evolved from the conventional charging station concept, now plays an increasingly important role in this dynamic sector.

But what exactly is an intelligent wallbox?

Intelligent wallboxes are small marvels of technology that use intelligent functions to optimise the charging process for electric cars. From adapting charging power to integration into smart home systems, they offer a wide range of options that go beyond simple charging. Unlike conventional charging stations, intelligent wallboxes can be connected to home Wi-Fi or LAN networks, enabling a variety of smart control and monitoring functions. While some might still think that a wallbox is just an electric car charger, it has in fact already become a central interface within the smart home. It connects photovoltaic systems, heat pumps, electric cars and the power grid in such a way that energy can be utilised and distributed efficiently. There is enormous potential. For OEMs, it’s a key product for positioning themselves in dynamic new markets relating to the energy transition, sector coupling and smart homes. But not every wallbox is suitable for this.

Key features of intelligent wallboxes

Advanced intelligent wallboxes have revolutionised the world of electric vehicle charging. They offer a core charging option but go far beyond this with a range of innovative features. These innovative devices differ from standard charging stations in a number of ways and are specifically designed to meet the needs of today’s electric car owners.

Charging power

One of the intelligent wallbox’s key features is its dynamic charging power. The ability to adapt charging power to the capacity of the electric vehicle in question is crucial for efficient and safe charging. The wallbox automatically recognises how much power the vehicle can take and adjusts the charging speed accordingly. This is particularly important as different electric car models have different charging capacities. The intelligent wallbox also takes into account the availability of domestic power. When more energy becomes available (e.g. solar power from a photovoltaic system), the wallbox can charge faster, while at peak load times it reduces its charging speed to help relieve demand on the electricity grid.


Universal compatibility is another key feature. Intelligent wallboxes are designed to work with a broad spectrum of electric car models. This flexibility is a major advantage for electric vehicle owners as they’re not restricted to one make or model. Universal compatibility also means that they are ready for any future vehicle models, making them a long-term and sustainable investment.


Security is a further important aspect. Intelligent wallboxes are equipped with advanced cyber security features to prevent unauthorised access, e.g. by hackers. Personal data, which is collected during the billing process, is thereby protected. Potential restrictions on the wallbox’s functions as a result of a hacker attack can also be avoided. On top of this, many models offer functions such as remote monitoring and control, which provides users with an extra level of security and convenience.

ISO certification

ISO 15118, titled “Road vehicles – Vehicle to grid communication interface”, is a pioneering set of international standards. This set defines standards for bidirectional communication between electric vehicles and charging stations. A central aspect of this standard is its promotion of the innovative “Vehicle to Grid” concept, which enables seamless energy flow management between vehicles and the electricity grid. ISO 15118 also simplifies the charging process through the implementation of “Plug & Charge”. This function automates the authorisation and billing of charging processes by using vehicle-stored payment data, which results in a smooth and user-friendly charging process.

What’s inside an intelligent wallbox?

Energy efficiency and use of solar power

An impressive feature of intelligent wallboxes is their ability to maximise energy efficiency. The integration of solar power plays a particularly important part in this respect and has significant advantages. Intelligent wallboxes can be connected to photovoltaic (PV) systems to use solar power generated directly on rooftops. This means that electric cars can be charged with environmentally friendly, renewable electricity, which not only brings down electricity costs but also reduces the user’s environmental footprint.

Smart home integration

A further notable advantage of intelligent wallboxes is their seamless integration into smart home systems. This integration allows users to control their wallboxes as part of a connected and automated household. As users can control their wallbox via a smartphone app or even voice assistants such as Alexa, Siri or Google Assistant, they can start, stop or schedule the charging process without having to be physically present at a charging station. As well as offering maximum convenience, this type of connectivity also makes it possible to efficiently integrate the charging process into everyday life. Charging can, for example, be set to take place during hours when demand for electricity is at its lowest or when there is plenty of solar power available, thereby further reducing costs and maximising the use of renewable energy. Integration into smart home systems also offers advanced monitoring and reporting options. Users can get detailed insights into their energy consumption, which in turn helps to improve energy management and save costs in the long term. Users are empowered to make more mindful decisions about their energy use with access to real-time data on charging and energy usage patterns.

Adaptability and the eFuture

The world of electromobility is constantly evolving and smart wallboxes are designed to keep up with developments. Their adaptability is one of the key features that sets them apart from conventional charging stations. Intelligent wallboxes can be updated with the latest features and safety standards through regular software updates, which makes them a future-proof investment. Such upgrades typically include improved charging algorithms, enhanced compatibility with new vehicle models and improved home energy system integration. The ability to adapt to future technologies also means that smart wallboxes are able to keep up with new developments in the automotive and energy industry, such as advances in battery technologies and changes in charging standards. This provides users with the assurance that their investment will remain relevant and valuable for years to come. 

Costs and cost-effectiveness

Incorporating an intelligent wallbox into the home or business environment offers the potential for significant operational cost savings above and beyond the initial purchase cost. These wallboxes allow end users to charge their electric vehicles more efficiently and cost-effectively, especially if used in conjunction with a photovoltaic system. Utilising solar power can substantially reduce the cost of charging an electric car compared to charging with conventional grid electricity. This is an environmentally friendly energy solution and offers financial savings at the same time.
