Abstract: A system includes a battery and a plurality of integrated circuits. The battery includes a plurality of battery cells. Each integrated circuit of the plurality of integrated circuits is coupled to a respective battery cell of the plurality of battery cells. Each integrated circuit includes at least one sensor configured to determine one or more operational characteristics of the battery cell coupled to the integrated circuit, and a transceiver configured to output a signal indicative of the one or more operational characteristics of the battery cell.

Abstract: Methods and devices for detecting electrical arcs are provided. A first wavelet transformation with a first mother wavelet is applied to a chronological sequence of current measurements (80) of a current through a lead, to obtain first wavelet coefficients. In addition, a second wavelet transformation with a second mother wavelet different from the first mother wavelet is applied to the chronological sequence in order to obtain second wavelet coefficients. On the basis of the first wavelet coefficients and the second wavelet coefficients, it is then determined whether an arc (10; 11; 24) is present.

Abstract: Techniques for monitoring an internal pressure of a battery cell, whereby a membrane that is part of an outer shell of the battery cell is used as an element of capacitive-based or inductive-based sensor circuitry in order to measure a change of capacitance or inductance under deformation of the membrane from the internal pressure of the battery cell. The change of capacitance or inductance may in turn be used to derive a value for the internal pressure of the battery cell.
