Description

The invention relates to a mobile energy supply system for battery-powered tools, in particular a portable tool supply system according to claim 1. In current technology, separate battery chargers are typically used on construction sites and in workshops, each designed for a specific battery system from a particular tool manufacturer. With a mixed fleet of machines, this necessitates operating multiple chargers in parallel, resulting in increased space requirements, extensive cabling, and a cluttered device layout. Mobile power distribution units are also known, providing multiple mains sockets in a portable housing. However, these power distribution units are generally not designed for directly charging tool batteries and lack integrated, manufacturer-specific battery charging units. Furthermore, portable charging or power boxes are known that integrate additional functions such as USB charging ports or lighting. These known solutions, however, usually represent merely a collection of individual functions without providing a modular, manufacturer-independent battery charging capability or a system architecture designed for the simultaneous operation of multiple functional units. The existing systems therefore have several disadvantages. In particular, the logistical effort required by multiple separate chargers is high, mobility on construction sites is limited by extensive cabling, and flexible adaptation to different battery systems is only possible to a limited extent or not at all. Furthermore, simultaneous operation of battery charging functions and external power supply is often only possible to a limited degree, while additional functions such as lighting or media playback are either missing or not integrated into a technically coordinated overall system. Based on this prior art, the invention aims to provide a mobile power supply system for battery-powered tools that enables flexible and manufacturer-independent power supply and charging of multiple tool batteries, while simultaneously providing an external power output for other electrical consumers and featuring a compact, clear, and portable design. Furthermore, the system should enable the simultaneous and safe operation of several functional units within a common housing, and should be particularly suitable for professional use on construction sites and in workshops. A solution to this problem is described by the features of claim 1. Accordingly, the inventive mobile power supply system for battery-powered tools is designed as a portable, lockable tool supply system and comprises a housing with a main body and a lid that closes it. This housing design provides protected accommodation for all functional units, making the system suitable for mobile use in harsh working environments, particularly on construction sites or in workshops. The lockability of the housing contributes to safe transport and protects the integrated electrical components from external influences. The system has at least one mains-side power supply for connection to an external AC power grid. This ensures a continuous and stable power supply to the system, regardless of the charge level of individual batteries. The mains-side power supply allows, in particular, the simultaneous operation of several energy-intensive functional units without any loss of performance or mutual interference. An energy distribution unit is arranged within the housing, which distributes the supplied mains power to the individual functional units. This central power distribution unit ensures a structured, reliable power supply to the connected modules and enables a clear functional separation between power input, power distribution, and energy consumers. This allows for reliable parallel operation of multiple consumers. The housing is designed to accommodate several functionally and mechanically separate units. This functional and mechanical separation allows individual units to be operated, maintained, or replaced independently without affecting the operation of the other units. Simultaneously, mutual thermal or electrical interference is reduced, increasing the operational reliability of the overall system. The functional units include at least two, preferably three, modular battery charging units, each designed as interchangeable charging slots. The modular design of the battery charging units provides high system flexibility, as different manufacturer-specific charging units can be used. This makes it possible to charge batteries from various tool manufacturers within a single system, eliminating the need for multiple separate chargers and significantly reducing space and cabling requirements. Furthermore, At least two, preferably three, externally located mains sockets are provided, enabling the external power supply of additional electrical devices. The external arrangement of the mains sockets allows direct access without having to open the housing. This allows the system to be used not only
