A method, device, and computer-readable medium for operating an electrical energy store is provided. The electrical energy store includes a storage cell for storing electrical energy and a control unit. State variables of the electrical energy store are detected. The state variables are transmitted to a computation unit outside of the electrical energy store. The electrical energy store is operated based on operating parameters provided by the computation unit.

Method for operating an electrical energy store

A method for determining a resistance parameter value of an electrical energy storage unit is disclosed, comprising the following steps:

Method for determining a resistance parameter value of an electrical energy storage unit, and corresponding device, computer program, machine-readable storage medium and electrical energy storage unit

A battery housing including at least one interior space for accommodating at least one battery, and including at least one contact element which, in a connection position, establishes a connection to a counter-contact element, the connection passing through the battery housing out of the interior space and/or into the interior space, the connection being cut off in an out-of-contact position with the counter-contact element, the counter-contact element being situated on an insulation component movable relative to the battery housing, which is movable from a first position, in which the counter-contact element and the contact element are in the connection position, into a second position, in which the counter-contact element and the contact element are in the out-of-contact position, the contact element being thermally insulated in the out-of-contact position by the insulation component.

A method is provided for transmitting measured data from cells of a battery system, having a plurality of individual cells, to a control device, comprising the steps of identifying a first individual cell for which measured data are to be furnished at a first measured-data quality; identifying at least one further individual cell or which measured data are to be furnished at a second measured-data quality; the first measured-data quality being higher than the second measured-data quality; identifying the first-quality measured data; identifying the second-quality measured data; transferring the first-quality measured data to a control device using a data connection; and transferring the second-quality measured data after the first-quality measured data have been transferred.

Method for data transmission on battery systems having a plurality of cells

A method for connecting battery cells in a battery is provided, the battery including at least one measuring battery cell and at least one standard battery cell in a series connection, the standard battery cell having at least a nominal capacity which is greater than a nominal capacity threshold, the measuring battery cell having a nominal capacity which is less than the nominal capacity threshold, the measuring battery cell having a switchable bypass, the method including: monitoring a state of charge of the at least one measuring battery cell; and bypassing the at least one measuring battery cell using the switchable bypass if the state of charge of the at least one measuring battery cell drops below a predefined state of charge threshold.
