This diploma thesis deals with the design and implementation of a new generation of charging station in order to create a portable device of compact dimensions. The device is placed in a tool box of size 396 x 296 x 187 mm and load capacity 20 kg. The LiFePO4 battery with a capacity of 512 Wh can be charged from the mains or be connected up to five photovoltaic panels via a junction box. Information about the current status is displayed on the LCD using the buttons. There are output sockets on both sides, namely USB-A, USB-C, 12 V and 230 V. The whole device is designed to be waterproof with a degree of protection IP 54 and has active air cooling. The result of this work is a functional charging station that can get by comparisons with products sold on the market. At the same time, the work shows that making a similar product is not technologically demanding and can serve as a guide if someone would like to build a similar device.
