摘要:
A method is used for monitoring a battery pack to check claims under guarantee that could possibly be invalid due to incorrect opening of the battery pack. The battery pack includes at least one electrochemical cell. When the battery pack is monitored, whether the battery pack has been opened is detected and any details relating to an event of opening are recorded in a non-erasable storage medium.

An arrangement includes at least one electrochemical cell, a housing, and a closure device. The housing is configured to contain the at least one electrochemical cell. The arrangement is configured such that removal or unregistered removal of one or more of the at least one electrochemical cell from the housing is prevented when the closure device is locked.

摘要:
A method for monitoring the conditions of driving systems can be used in particular to control driving systems in hybrid vehicles with particular consideration given to the exhaust emission. The method monitors the conditions of driving systems that comprise an internal combustion engine and an electric motor with an energy source. A first power value for operating the internal combustion engine and a second power value for describing the power that can be provided by the energy source are ascertained, and the first and second power values are compared with each other to monitor the conditions of the driving system. The driving system is controlled dependent on the result of the comparison.
摘要:
A method to diagnose an exhaust gas sensor disposed in the exhaust gas region of an internal combustion engine, wherein provision is made for a comparison of a measurement for at least one exhaust gas component with a measurement of the exhaust gas component, which is ascertained on the basis of an exhaust gas sensor signal, and a device to implement the method are proposed. The diagnosis is only implemented if a change in at least one operating parameter of the internal combustion engine and/or at least one parameter of the exhaust gas is detected during the running operation of the internal combustion engine. Provision is made in the diagnosis for an averaging of the measurement for at least the one exhaust gas component as well as of the measurement for the exhaust gas component, which is provided by the exhaust gas sensor. Provision is additionally made for a subsequent comparison of the two averages and for an error signal to be provided if the difference of the two averages exceeds a difference threshold value. The procedural approach allows for the diagnosis to occur without a diagnostic intervention into the operation of the internal combustion engine and without an intervention into an open-loop control, which if need be is present, for the metering of a reagent substance, which is introduced into the exhaust gas region of the internal combustion engine to convert at least one exhaust gas component.
摘要:
A method for operating an internal combustion engine and a device for executing the method provide for diagnostics of the exhaust system in which an exhaust-gas treatment device for converting at least one undesirable exhaust gas component is situated. A measure for the conversion is determined from the exhaust gas component, ascertained upstream from the exhaust-gas treatment-device and measured downstream from the exhaust-gas treatment device and compared to a predefinable threshold value. An error signal is issued when the threshold is not met. The approach makes it possible in particular to detect a manipulation in the exhaust system such as the use of a dummy in the exhaust-gas treatment device or, for example, a deliberately defective lining of a component situated in the exhaust-gas treatment device.
摘要:
The disclosure relates to a method for determining at least one state of a plurality of spatially combined battery cells connected to each other by circuitry. The state is determined by observing battery cells by means of at least one observer structure. A subset of a plurality of battery cells is observed and the state derived from the observation is determined for more battery cells than for the observed battery cells. The disclosure further relates to a battery comprising a battery management system, which is configured such that the method according to the disclosure can be carried out thereby. The disclosure also relates to a motor vehicle comprising a battery according to the disclosure.
摘要:
A method for operating a catalytic converter used for purifying the exhaust gas of an internal combustion engine, and a device for implementing the method, which provide for an open-loop or closed-loop control of the reagent fill level in the catalytic converter to a predefined storage setpoint value. The targeted stipulation of the storage setpoint value ensures, on one hand, that in non-stationary states of the internal combustion engine, there is a sufficient quantity of reagent available for the completest possible removal of at least one unwanted exhaust-gas component, and on the other hand, a reagent slip is avoided.
摘要:
A method for monitoring a component situated in an exhaust gas region of an internal combustion engine in which the low pass behavior, which is determined by the heat capacity of the component, is monitored by a valuation of a measure of a first exhaust gas temperature, which appears upstream of the component that is to be monitored, and of a second exhaust gas temperature, which is recorded by a second temperature sensor downstream from the component to be monitored.
