Abstract: The invention relates to a drive (1) having an energy storage device and a method for storing brake energy. A drive (1) has an energy storage device having a hydrostatic piston engine (9) and a storage element (11) which is connected thereto. In a high-pressure storage line (10), an adjustable throttle location (15) is arranged between the piston engine (9) and the storage element (11). During the braking operation, the adjustable throttle location (15) is adjusted in accordance with a detected requested brake torque. The pressure medium is conveyed from the hydrostatic piston engine (9) via the adjustable throttle location (15) into the storage element (11).

Abstract: A method for ascertaining operating parameters of an electrochemical storage battery, taking into account electrolyte stratification. The method including a) determining a first functional relationship between no-load voltage and state of charge as a value for the withdrawable charge in relation to nominal capacity of the storage battery, which is obtained in the state having electrolyte stratification in a discharge phase using the charge conversion since a prior no-load phase or pre-charge; b) determining a second functional relationship between no-load voltage and state of charge as a value for the withdrawable charge in relation to nominal capacity of the storage battery, obtained in the state having electrolyte stratification in a discharge phase using an accumulated charge conversion; and c) ascertaining operating parameters from the point of intersection of the first and second functional relationships and/or the slope of straight lines for describing the first and/or second functional relationships.

Abstract: Provided is a method for charging a battery that dynamizes the charging phase of the battery, thereby enabling optimum charging. The dynamization of the charging phase is intended to achieve effective mixing of the battery acid and/or depolarization of the electrodes and ultimately result in improved receiving of the charging current. In this context, the charging method can be carried out according to at least two different methods. In a first method, targeted discharges result in depolarization of the electrodes due to locally decreasing acid density, and in a second method the battery acid is reliably mixed as a result of temporary increasing of the charging voltage via the so-called gassing voltage of the battery. Both methods result in improved battery charging. In an embodiment of the method, the two methods are combined.
