Paper deals with the construction of the electric-kart as a student project. The project was solved by two master thesis and a few semester thesis. The power of this kart is equal to the kart for rent equipped with the combustion engine. The chassis is equipped with Li-ion batteries and DC-motor.

This paper deals with the construction of the electric kart with LiFeYPO 4 . Electric kart is designed to replace conventional engine karts which are commonly used in karts rent business. It includes also descriptions of chosen parts like LiFeYPO 4 batteries, MOSFET converter, sensors and electronics control system. The topology of electrical equipment is based on a CAN bus and allows further expansions by students projects. Today they, modern LiFeYPO 4 are used as a power source of electric kart. This batteries allows rapid recuperation of the kinetic energy. Terms-Batteries, Battery management systems, converters

In this paper a design method for mechatronic functions in an early design phase under consideration of the requirements of functional safety is proposed [14]. The goal of the method is to discover threats for the safety goals and to prove or optimize the diagnostic mechanisms. At the current design process a lifetime endurance test is performed in a late project phase. In order to avoid unexpected late design changes the method should be applied in an early design phase. The method is an additional way to avoid design failures for E/E functions with special focus on aging in the field of functional safety applications. The method is developed out of three standards VDI 2221 methodology for development and construction of technical systems and products [1]), VDI 2206 design methodology for mechatronic systems [2] and the ISO 26262 road vehicles -Functional Safety [3] by using the V-Model. Furthermore, a core element of the design method is simulating aging effects by applying VHDL -AMS. To demonstrate the design methodology a sensor out of the EGAS function is chosen as a safety relevant automotive system. The limitation is the availability of aging data for electrical components.

The goal of this paper is to describe the hardware for a rail traffic simulator. It has been designed as a teaching aid for the Department of Applied Electronics at the University of West Bohemia. The simulator was developed for verification of the reliability of railway safety algorithms for direct access of the human factor. The simulator consists of: rails, position balises, station units, rail vehicles, a train cabin and a safety application, which is verified. Communication between the elements of the system is based on wireless transmissions. The hardware withstood well during testing by randomly selected people. It fully meets the requirements of the system.
