Definitions

  • the present invention relates to a control method for controlling an output power of a battery device and an operating power of a fuel cell system, a control device for carrying out such a method, and a hybrid drive system with such a control device.
  • hybrid drive systems are to be used in order to drive modern vehicles with an electric drive device. For this it is necessary to supply the electrical drive device with electrical energy. In such hybrid drive systems, this takes place from a battery device and a fuel cell system. Depending on the power requirement in the respective operating situation of the hybrid drive system, a different composition of the output power and the operating power can meet the current power requirement.
  • a disadvantage of the known solutions is that when combining the output power and the operating power to meet the power requirement, only the current situation is considered. At most, it is known that individual damage mechanisms of the battery device and/or the fuel cell system are taken into account in order to avoid or reduce corresponding damage to the individual components. However, this can mean that although the damage to one of the two components is reduced, the other component with normal or increased damage does not achieve the desired service life for the hybrid drive system.
  • the object of the present invention to at least partially eliminate the disadvantages described above.
  • a control method serves to control an output power of a battery device and an operating power of a fuel cell system for an electric drive device of a hybrid drive system.
  • Such a control procedure is characterized by the following steps:
  • a control method is based on the assumption that the operating performance of the fuel cell system and the output power of the battery device are not only recorded over a longer recording period during operation of the hybrid drive system, but are also stored. For example, the electrical power output and the electrical operating power can be monitored, recorded and stored over a period of several hours, several days or even several weeks. In particular, this makes it possible to determine the damage status, which will be explained later, for the fuel cell system and the battery device. men and to take into account.
  • An essential component is that a future prognosis for the battery device and the fuel cell system can now be determined on the basis of the past observation and the stored values for the operating power and the output power.
  • a damage model for the battery device and a further damage model for the fuel cell system, which is equipped with the recorded and stored values for the operating power and/or the output power.
  • a prognosis can be made as to how the damage to the battery device and the fuel cell system will continue to develop in the future.
  • Such a damage prognosis can, for example, contain a correlation to a desired minimum service life of the hybrid drive system.
  • other damage predictions for example a reduction in the maximum possible output power and/or operating power, a maximum storage capacity of the battery device or the like, are also conceivable individually or in combination.
  • the core idea of the present invention is that a future analysis is carried out by, for example using one or more damage models, determining a battery damage prognosis for the battery device and a fuel cell damage prognosis for the fuel cell system.
  • a future analysis is carried out by, for example using one or more damage models, determining a battery damage prognosis for the battery device and a fuel cell damage prognosis for the fuel cell system.
  • the core idea according to the invention will now carry out a control method according to the invention in addition to detecting the current power requirement.
  • the control method will take into account the recorded and stored operating performance and output performance of the past in order to determine a battery damage prognosis and a fuel cell damage prognosis.
  • the control and in particular the specification of the target output power and the target operating power can now be based on the result of these damage forecasts.
  • the battery damage prognosis currently determined is such that there is a certain probability that the battery device will not reach the desired minimum service life, then despite the increased efficiency when the increased power requirement from the battery device is met, the output power of the battery device is not increased, but rather a reduction in efficiency Purchase taken, so that the performance requirement is met by an increased operating performance of the fuel cell system and at the same time the specific battery damage forecast is taken into account in order to increase the probability of reaching the minimum service life for the battery device.
  • the more frequently a control method according to the invention is used to meet performance requirements in a hybrid drive system, the higher the probability that all subcomponents of the hybrid drive system will also reach the minimum service life in the desired way.
  • the detection periods for the detection and storage of the operating power and the output power are preferably of the same length and are preferably continuous or essentially continuous, that is to say uninterrupted, over the respective operating times. Storage over the course of time is therefore carried out.
  • other operating parameters and/or damage parameters for the fuel cell system and/or the battery device can also be recorded and also stored.
  • a vehicle for example a truck
  • a desired target service life with a high degree of probability. If, for example, a desired target service life of 1.5 million operating kilometers is specified for a truck, the control method according to the invention can, at least with regard to the individual components of the hybrid drive system, take into account the future prognosis for the damage situation of the fuel cell system and the battery device, so that the probability increases that this target service life is actually achieved to reach or even exceed.
  • damage models can be used for forming and determining the respective damage prognosis.
  • Such damage models can be determined, for example, on test benches for the battery device, the fuel cell system and/or the hybrid drive system.
  • neural networks or artificial intelligences of a different design can also be used.
  • the balance of the fuel cell damage prognosis and the battery damage prognosis is taken into account in a control method according to the invention for the specification of the target output power and the specification of the target operating power.
  • normalization is particularly advantageous for the fuel cell damage prognosis and the battery damage prognosis.
  • a balance ie an equalization, can be taken into account, which results in the damage mechanisms damaging the fuel cell system and the battery device quantitatively and uniformly during operation of the hybrid drive system.
  • a compensation can take place in this way in order to compensate for increased damage to one component by protecting it over a certain period of time and compensating for increased damage to the other component.
  • a balance of the damage or a balance of the damage that actually occurs is possible for the future by balancing the damage forecasts for the fuel cell system and the battery device.
  • a battery damage status for the current damage situation of the battery device and a fuel cell damage status for the current damage situation of the fuel cell system are determined and taken into account for the specification of the target output power and/or the target operating power. It is thus possible, in particular in a quantitative and/or normalized manner, to determine how severe the current damage situation is in the form of the damage status for the battery device and the fuel cell system. In other words, a view of the past is combined with a view of the future, so that the current damage situation as a result of the operating mode in the past is correlated with the damage prognosis to be expected in the future.
  • a minimum service life is specified until a maximum battery damage status is reached and until a maximum fuel damage status is reached. If the two damage statuses are normalized, then the maximum battery damage status represents 100% damage and the maximum fuel cell damage status also represents 100% damage to the fuel cell system. This makes it possible to specify the minimum service life and, for example, with regard to the desired kilograms meter performance, a desired hourly performance or the like, based on a control method according to the invention.
  • the setpoint operating power and the setpoint output power are specified taking into account remaining battery damage and/or remaining fuel cell damage.
  • the residual damage can also be used in a normalized manner, based on kilometers and/or operating hours, or in an absolute manner.
  • the battery damage prognosis and/or the fuel cell damage prognosis are normalized in a control method according to the invention .
  • a normalization can, for example, take place in a dimensionless manner.
  • a percentage normalization to a hundred percent fulfillment for example a minimum service life, a minimum number of operating hours and/or a minimum mileage, is also conceivable here within the meaning of the present invention.
  • the normalization makes it even easier and simpler to carry out the control with regard to balancing the different damage mechanisms of components and/or subcomponents.
  • the battery damage forecast and/or the fuel cell damage forecast have partial component damage forecasts.
  • a division into partial damage forecasts can be possible in order to also provide partial residual damage and/or partial damage status.
  • damage mechanisms for the membranes contained therein, catalyst materials used or the like are contained in a fuel cell system.
  • the use of sub-component damage forecasts means that an even more detailed detection of the individual damage mechanisms is possible here, in order to carry out even more precise balancing at the sub-component level using a control method according to the invention.
  • a damage model is used in a control method according to the invention for determining the battery damage prognosis and/or the fuel cell damage prognosis.
  • a characteristic diagram, an algorithm and/or the use of an artificial intelligence can be provided underneath, for example.
  • Separate damage models for the fuel cell system and the battery device are also necessary.
  • partial damage models for partial components of the fuel cell system and/or for partial components of the battery device can also be used.
  • the damage model is improved based on recorded and stored operating performance, based on recorded and stored output power and/or based on other damage parameters.
  • This evaluation also makes it possible to provide a conclusion in the form of a self-learning system in the damage model, so that incorrect forecasts from the past can be taken into account for future forecasts, which in turn future forecasts become more and more accurate with the ongoing use of a control method according to the invention.
  • a replacement of the battery device, the fuel cell system, a component of the battery device and/or a component of the fuel cell system is instructed in the event of a negative battery damage prognosis and/or a negative fuel cell damage prognosis.
  • This is therefore to be understood as a signaling when a negative damage prognosis is interpreted in such a way that reaching the minimum service life is not guaranteed.
  • the damage prognosis can contain the information that the desired minimum service life cannot be achieved even with maximum protection and/or use of regeneration situations.
  • an exchange of a sub-component can be made available at an early stage in order to to avoid a sudden replacement with a standstill of the hybrid drive system in the future.
  • this signaling is selected in such a way that a component that can be replaced particularly easily and inexpensively is selected, which can now be subjected to maximum stress at an early stage while protecting the remaining components and avoiding any protection.
  • a further subject matter of the present invention is a control device for controlling an output power of a battery device and an operating power of a fuel cell system for an electric drive device of a hybrid drive system.
