Abstract: An electric vehicle includes an electric drive device, first and second energy storage devices, and a bidirectional DC converter. The drive device, the DC converter, and the second energy storage device are connected to each other via a common intermediate circuit. The intermediate circuit includes an intermediate circuit voltage, the first energy storage device includes a storage voltage and is connected to the intermediate circuit via the DC converter. The drive device is supplied with drive energy by the first and/or second energy storage device. The intermediate circuit voltage is converted into the storage voltage in a first converter direction by the DC converter. The storage voltage is converted into the intermediate circuit voltage in a second converter direction by the DC converter. The first converter direction is activated when charging the second energy storage device and is deactivated when discharging the second energy storage device.

Abstract: A U-shaped shoeing for horses comprises a running surface and a hoof contact surface has reinforcing layers embedded in a plastic matrix. The reinforcing layers longitudinally extend and follow the U-shaped curvature of the shoeing. Reinforcing layers extend transversally to their longitudinal extension from the running surface towards the hoof contact surface. Reinforcing layers are arranged on the hoof contact surface side, parallel to the hoof contact surface, parallel to the hoof contact surface, or parallel to the hoof contact surface and penetrate in the matrix as far as below the hoof contact surface or form the hoof contact surface. The reinforcing layers may be in the form of textile tube structures produced from fiber strands containing a multiplicity of fibers. The invention also relates to a production method for such a shoeing.

Abstract: A horseshoe for horses, in particular for racehorses when taking part in competitions. The horseshoe is produced from thermoplastic polymer material or from fiber-reinforced thermoplastic polymer material. The thermoplastic polymer material is selected from thermoplastic polycarbonates or fiber-reinforced thermoplastic polycarbonates. The horseshoe may be constructed from a core of fiber-reinforced plastic material, which is sheathed in a functional layer made of plastic. The core may also be formed from a fiber-reinforced thermoplastic polymer material, such as a fiber-reinforced thermoplastic, and the functional layer may be formed from a thermoplastic polycarbonate material or a fiber-reinforced thermoplastic polycarbonate material, such as a thermoplastic or a fiber-reinforced thermoplastic. The horseshoe may be produced by thermoplastic injection molding methods.

Abstract: There is shown and described a shoeing for horses, in particular for racehorses being used in competition, constructed from a core made of fiber-reinforced plastic material which is surrounded by a functional layer made of plastic. According to the invention it is provided that the core is formed substantially from a fiber-reinforced thermoplastic polymer material (i.e. a fiber-reinforced thermoplastic) and the functional layer is formed substantially from a thermoplastic polycarbonate material or a fiber-reinforced thermoplastic polycarbonate material (i.e. a thermoplastic or a fiber-reinforced thermoplastic). Furthermore there is shown and described a thermoplastic injection molding method for producing the shoeing.
