A mobile transport system includes a drive unit having a first drive wheel rotatable about a first drive axis and a second drive wheel rotatable about a second drive axis, the drive axes extending in a transverse direction. The drive unit includes a swivel and a drive frame. The drive frame is pivotable about a steering axis relative to the swivel. The drive unit includes a marking carrier that is disposed in a stationary manner relative to the drive frame, and on which optically detectable markings are applied. The drive unit includes a camera for detecting the markings and is disposed in a stationary manner relative to the swivel.

Mobile transport system

A mobile transport system includes a vehicle frame, first and second pairs of support wheels, first and second drive wheels, and a swing frame pivotable about an swing axis relative to the vehicle frame. The first support wheels are disposed on the vehicle frame, and the second support wheels are disposed on the swing frame. A drive unit including a drive frame is disposed on the swing frame. The first drive wheel is rotatably supported on a first swing arm pivotable about a first swing axis relative to the drive frame, and the second drive wheel is rotatably supported on a second swing arm pivotable about a second swing axis relative to the drive frame. The drive frame is pivotable about a steering axis relative to the swing frame.

In a method for operating an electric vehicle, including a first energy storage device (e.g., a rechargeable battery storage device), a second energy storage device (e.g., a double-layer capacitor device), an energy supply unit which provides energy, for charging the first and/or second energy storage device, and a first electrical consumer connected to the second energy storage device via an intermediate circuit, the first energy storage device is connected to the energy supply unit via a bidirectional converter unit, the second energy storage device is connected to the energy supply unit, a first power flows from the first energy storage device to the second energy storage device if an intermediate circuit voltage falls below a definable voltage, and a second power flow from the second to the first energy storage device is prevented.

Method of operating an electric vehicle and electric vehicle

In a method for operating an electric vehicle, including an electrical drive device for driving the vehicle, a control device for controlling the driving of the vehicle, a first energy storage device for supplying the control device with a first DC voltage, a second energy storage device for supplying the drive device with a second DC voltage, and an energy supply unit providing an output DC voltage, the first energy storage device is connected to the energy supply unit via a converter device, the second energy storage device is connected to the energy supply unit, the converter device converts the output DC voltage into the first DC voltage, a first power flow from the first energy storage device to the second energy storage device is prevented and a second power flow from the second energy storage device to the first energy storage device is prevented.

Method for operating an electric vehicle and electric vehicle

In a transport system and method for operating a transport system the transport system includes a first mobile component and a second mobile component as well as a transport rack. Bearing rollers for moving the transport rack on a driving surface are disposed on the transport rack, in particular, the mobile component is drivable on the driving surface. Each mobile component has a linear axle and a control as well as wheels driven by an electric motor. The first mobile component is able to drive underneath the transport rack in a first region of the transport rack, and the second mobile component is able to drive underneath the transport rack in another, i.e. second, region of the transport rack. The transport rack is able to be raised by extending the linear axles of the mobile components, in particular is able to be raised in such a way that the bearing rollers of the transport rack lose physical contact with the driving surface. A communications channel is provided between the first and the second mobile components, the communications channel serving as a transmission channel for data of at least one master-slave control, the first mobile component acting as a master and the second mobile component acting as a slave.
