Abstract: The present invention provides methods and apparatuses for determining a liquid level inside a container by using an effective capacitance associated with one or more sense electrodes that are located inside the container. Embodiments may support different types of liquids, including water, and support different electrical appliances, including electric kettles, coffee makers, and water treatment appliances having a non-transparency housing such as stainless steel and black color Lucite or glass that cannot directly indicate the water level. A value of capacitance characteristic associated with a sensing electrode is determined. The water level may be displayed to the user on any kind of electronic panel, e.g., liquid crystal display (LCD), light emitting diode (LED) display, or vacuum fluorescent display (VFD). Also, a correction factor may be applied to a determined capacitance associated with a sensing electrode to compensate for the operating temperature of the sensor electrode and the liquid.

Abstract: A method for controlling the temperature of at least one battery element, a battery, and a motor vehicle that has the battery includes specifying a temperature value, and determining the cool-down behavior of the at least one battery element beginning at a first temperature. A first point in time, at which the battery temperature will have reached or fallen below the temperature value, is determined by evaluating the cool-down behavior. Subsequently, a second point in time for a beginning of the charging or discharging of the at least one battery element is determined. If tmin<t_end, heat is applied to the at least one battery element in such a manner that the battery temperature at the second point in time is higher than or equal to the temperature value. The method can be used to avoid damage to the battery element during charging and discharging of the battery element.

Each of said fuel cells comprises a cathode-electrolyte-anode unit (7) and a perforated film (1) which distributes a combustible gas across the first electrode surface thereof, supports the cathode-electrolyte-anode unit (7), and is combined into a cassette (4) that is provided with a hollow space along with an additional structure (3). The combustible gas reaches the first electrode (7A) via said cassette (4).

Abstract: A fuel cell includes a cathode-electrolyte-anode unit, and a perforated foil structure distributes fuel gas over an electrode surface thereof. Longitudinal axes of at least some of the holes forming perforations in the foil are inclined differently relative to the foil surface such that, near a fuel gas feed, the outlet openings of the holes facing the electrode are oriented at least slightly toward the area of the fuel gas outlet from the fuel cell. Near a fuel gas outlet, the inlet openings of the holes facing the electrode are oriented at least slightly to the area of the fuel gas feed. However, holes whose inlet openings facing away from the electrode are oriented toward the fuel gas feed, and holes whose outlet openings facing away from the electrode are oriented toward the fuel gas outlet, may also be arranged alternately side-by-side.
