The invention relates to a method for controlling the service life of an energy storage module (1), wherein a state of health (SoH) of the energy storage module (1) is known at different times (t). In order to improve the control of the service life of an energy storage module (1), it is proposed that a speed of ageing (vSoH) is determined from a first known state of health (SoH1), in which the energy storage module (1) is at a first time (t1), and a second state of health (SoH2), in which the energy storage module (1) is at a second time (t2), wherein a time (tEND_calc) of a determined end of service life is calculated from the speed of ageing (vSoH) and from one of the states of health (SoH), wherein depending on the time (tEND_calc) of the determined end of service life a measure for changing the service life of the energy storage module (1) is applied.

The invention relates to a hybrid driving system for a vehicle comprising a generator connected to an internal combustion engine (1) which is linked to an electric driving motor (6) by means of a generator frequency converter, an intermediate voltage circuit and a motor frequency converter. An energy-storage reservoir (7) is connected to the intermediate voltage circuit. According to said invention, the intermediate voltage circuit is divisible into two partial intermediate circuits (3, 4) by means of a first switch (8). Each partial intermediate circuit comprises at least one driving motor (5, 6, 12) connected by means of the corresponding motor frequency converter. The aim of said invention is to adjust the hybrid driving system. For this purpose, when the voltage (U3) in the energy-storage reservoir (7) is lower than the voltage of the corresponding intermediate voltage circuit, the first switch (8) arranged between two intermediate circuits (3, 4) switches off the link and the first switch (8) becomes an open conductor only.

The invention relates to a hybrid drive system for a vehicle; comprising an intermediate circuit (3) and an energy accumulator (5). According to the invention, the energy accumulator (5) is connected to the intermediate circuit (3) by means of a diode (6), whereby a transistor (7) enabling current to flow in an opposite direction is connected parallel thereto. The transistor (7) is placed in a blocking position in order to discharge the energy accumulator (5) and the diode (6) enables current to pass. If the energy accumulator (5) is not used, the diode (6) is also blocked by increasing the voltage (8) of the intermediate circuit (3) with the aid of the voltage (14) on the energy accumulator (5). In order to charge the energy accumulator (5), the transistor (7) is conductingly switched. The diode (6) does not allow the current to pass in this direction.

The invention relates to a control system for a hybrid system consisting of at least one energy accumulator (1) and one energy source (2), wherein the control system determines accumulation power (P3) supplied or received by the at least one energy accumulator (1) and a source power (P2) to be supplied by the energy source (2) on the basis of a charged state (Z) of the at least one energy accumulator (1), a set operating point (P11) of the energy source (2) and a momentary system power (P1) to be supplied according to at least one optimization criterion. In order to obtain a particularly flexible control system, the invention provides that at least one charge limiting value (P4, P7, P8) and at least one discharge limiting value (P5, P9, P10) for the at least one energy accumulator (2) are also considered for determining the accumulation power (P3) and the source power (P2) and that the at last one charge limiting value (P4, P7, P8), the at least one discharge limiting value (P5, P9, P10), the power limiting value (P12) and the set operating point (P11) can be parameterized through an interface (5) of the control system.

A process and device are disclosed for compensating a fault voltage (U fault 2) of a pulse-controlled inverter that supplies an induction machine, the fault voltage being due to a locking time (Tv) and to on-state voltages (UF) of the current rectifying valves of said pulse-controlled inverter. The load angle (εi) and the current sector in which the current space vector (i*s) is located at any given moment are determined depending on the current components (i*d),i*g) and the intensity of the fault voltage (UKLF) is determined depending on parameters (Tv, TP, UZK, Uf) of the pulse-controlled inverter. The position of the fault voltage space vector (U fault 2) is calculated from the determined current sector and the determined fault voltage vector (U fault 2) is added to the set value of the stator space vector (U*s). The fault voltages generated by the pulse-controlled inverter are thus easily compensated.
