The invention relates to an energy storage module for an energy storage device, comprising an energy storage cell module which has a storage cell series circuit of at least two energy storage cells, comprising a coupling device, which comprises a plurality of coupling elements and is designed to selectively connect the energy storage cell module into an energy supply line of the energy storage device or to bypass the energy storage cell module in an energy supply line, and comprising a driver module which is designed to generate drive signals for the plurality of coupling elements. The driver module has a first energy supply connection and a second energy supply connection. The first energy supply connection is connected to a first end connection of the energy storage cell module via a first supply line and to a first node point between two energy storage cells of the storage cell series circuit via a second supply line. The second energy supply connection is connected to a second end connection of the energy storage cell module via a third supply line and to a second node point between two energy storage cells of the storage cell series circuit via a fourth supply line. The second node point lies between the first node point and the first end connection.

Internal energy supply of energy storage modules for an energy storage device, and energy storage device with such an internal energy supply

A method for remotely accessing at least one of at least one CAN node arrangement of a CAN bus arrangement associated with the vehicle during vehicle operation, the CAN bus arrangement being associated with a CAN gateway arrangement for coupling to an external network, inn which the method includes the steps of communicating an initialization control message from the CAN gateway arrangement to the at least one CAN node arrangement using the CAN bus arrangement, the initialization control message including a CAN node arrangement identifier code, comparing the CAN node arrangement identifier code with a unique CAN node arrangement identifier code stored at each of the at least one CAN node arrangement for determining a selected CAN node arrangement based on the CAN node arrangement identifier code and the unique CAN node arrangement identifier code, processing the initialization control message using the selected CAN node arrangement, communicating a data addressing message from the CAN gateway arrangement to the selected CAN node arrangement, the data addressing message including at least one memory address of the data to be at least one of accessed, controlled and retrieved, communicating at least one data reply message from the selected CAN node arrangement to the CAN gateway arrangement, in which the at least one data reply message includes a data payload, incorporating at least the data payload of the at least one data reply message using a communication protocol of the external network for communication of the data payload to the remote accessing arrangement, and communicating an end control message from the CAN gateway arrangement to the selected CAN node arrangement using the CAN bus arrangement.

Apparatus, method and system for remotely accessing and/or controlling can node arrangements, including vehicle electronic control units, during vehicle operation

A method and a device for reducing overvoltages is described. A switch and a load are connected in series between a first and a second terminal of a voltage source. The switch is triggered in such a way that the current flow through the load is released if the voltage exceeds a threshold value.
