Abstract: A positive terminal of a battery may act as an antenna ground plane for communicating battery status information. The positive terminal of the battery may include a first electrically conductive external surface with a first surface area. The negative terminal of the battery may include a second electrically conductive external surface with a second surface area less than the first surface area. An antenna impedance matching circuit may electrically connect to a communication circuit, an antenna, and the positive terminal of the battery. Thus the positive terminal of the battery may act as a ground plane for the antenna.

Abstract: In an electrical device, in which the load is supplied by a battery cascade, the voltages of the batteries of the battery cascade must be measured with high precision in order to start charge equalization and prevent undervoltages or overvoltages, wherein if possible favorable components should be used simultaneously.

Furthermore, the positive pole of the second battery (A2) can be coupled between the resistor (R1) and the capacitor (C2) by way of a second switch (S2).
