The present invention relates to an actuating apparatus for triggering at least one pyrofuse, comprising a supply voltage connection for connection to a supply voltage, at least one triggering output for connecting the at least one pyrofuse and applying a triggering current to the pyrofuse, a signal input for receiving a triggering signal which indicates a state which extends the triggering, and at least one actuating circuit, which can be connected to the supply connection, for providing the triggering current at the triggering outlet in accordance with the received triggering signal, wherein said actuating circuit comprises a field-effect transistor stage for connecting the supply voltage through to the triggering output in accordance with the received triggering signal.

Actuating apparatus for triggering at least one pyrofuse, and energy storage device comprising a pyrofuse of this kind

The present invention relates to an energy storage device, comprising a switchgear cabinet housing in which a plurality of receiving spaces are provided, in which receiving spaces at least one control device and a variable number of electrical storage blocks are accommodated in an exchangeable manner, wherein the storage blocks can be selectively interconnected in series or in parallel and are connected to power connections by means of a current controller. Therefore, it is initially proposed to form the control device which is installed in the switchgear cabinet housing and the associated power electronics components themselves in a reconfigurable or variable manner in order to allow the controller and power electronics to be matched to another mode of operation or another application, without having to exchange the control and power electronics module and provide corresponding wiring for this purpose.

Energy storage device

The invention relates to a bus-capable device having an input interface and an output interface for connecting to a serial bus, particularly a CAN bus, wherein the input interface and the output interface each have at least one signal line connection, and further having a terminating resistor for terminating the bus and a switch apparatus for switching the terminating resistor active as a function of the connection status of the input and output interfaces, wherein the input interface and the output interface each having a supply voltage connection for providing a supply voltage to the output and/or input interfaces of a respective next bus-capable device and a feedback connection for receiving the supply voltage from an output and/or input interface of a respective next bus-capable device, wherein the switch apparatus has an evaluation circuit for determining the presence of the supply voltage at the feedback connections of the input and output interfaces and an activation circuit for switching the terminating resistor active when the supply voltage is found by the evaluation circuit to be absent from the feedback connection of the input interface and/or from the feedback connection of the output interface.

Bus-capable device arrangement having a switchable terminating resistor

The present invention relates to an energy storage device, comprising power terminals for connecting to a voltage circuit of power electronics of a drive system, which drive system can be controlled by an external system controller as well as at least one electrical storage block; at least one power converter for connecting the voltage circuit of the power electronics of the drive system to an internal voltage circuit of the storage block; and a control device for controlling the at least one power converter. Said control device has a controller board having output and/or feed-in control means for controlling the power converter for the outputting of current from/feeding of current into the storage block, and/or voltage closed-loop and/or open-loop control means for the closed-loop and/or open-loop control of the output voltage of the energy storage device. According to the invention, said control device has an adaptation board, which is connected to the controller board. The adaptation board comprises a plurality of connection terminals for differently designed external system controllers, at least one communication interface for communicating with the controller board of the control device, and at least one adaptation circuit for adapting and transferring signals between the connection terminals of the adaptation board and the controller board.
