    Test and test bench system for at least partially electrified engines
    The invention relates to a test and test bench system for at least partially electrified engines, in particular for hybrid or fully electrified vehicles, comprising a test automation system with measurement technology and interfaces, as well as a battery emulator that supplies a Leistungselektnonik or an electric motor and a battery model, the current voltage values at the DC Output calculated to the vehicle electronics. The development of hybrid (HEV) and fully electrified vehicles (EV) requires appropriate test and test rig systems. An important component of such a test and Prüstandssystems represents the battery emulation (battery simulation), which simulates the behavior of a real battery (high-voltage memory) so that test cycles are reproducible or that tests are even possible, if only battery prototypes are present, the development not available. Important in this simulation are above all the electrical and thermal behavior as well as the state of charge. Furthermore, the behavior for charge and discharge differs for a real battery.
    The object of the present invention was therefore a test and test bench system in which the tests of, in particular traction batteries can run even more realistic.
    To achieve this object, the invention provides that the battery emulator simulates the different charging and discharging behavior of real batteries.
    A first exemplary embodiment for this is characterized in that the battery model is defined by an electrical equivalent circuit diagram whose components are assigned different values for the charging or discharging process.
    It may also be provided that the battery model for the charging or discharging process is parameterized differently or has additional properties.
    Advantageously, a further embodiment of the invention is characterized in that the battery module contains a state of charge calculation and / or a model for simulating temperature influences.
    An inventive system may also include the features that a higher-level automation system specifies test cycles, wherein the battery emulator values for state of charge and temperature are specified.

    In the following description, the invention will be explained by way of example and with reference to the accompanying drawings.
    1 shows a schematic representation of a test bench topology with battery emulator, and FIG. 2 is a diagram showing the different behavior of a battery for charging or discharging.
    A test and test bench system according to the present invention and as shown by way of example in FIG. 1 consists of a test automation system 1 with corresponding measurement technology 2 and interfaces, as well as the battery emulator 3 with connection point. The battery emulator 3 supplies the power electronics (inverter) 4 or the electric motor 5 and / or further electrical or electronic loads, as represented by the symbolic line 5a parallel to the electric motor 5. A higher-level automation system can specify test cycles, whereby the battery emulator 3 is given values for state of charge and temperature.
    The battery emulator 3 calculates the current voltage values at the DC output 6 to the power electronics 4 via a corresponding battery model. A control unit 7 is connected, preferably via CAN bus, to both the battery emulator 3 and the power electronics 4.
    The battery model generally consists of an electrical equivalent circuit diagram with corresponding component values and further preferably comprises a state of charge calculation and a model for simulating temperature influences.
    The electrical equivalent circuit diagram in the context of the battery model thereby defines the behavior of the simulated battery as a function of the load, i. the current load through the inverter / E-Nlotor combination 4, 5. This equivalent circuit diagram may contain a different number of components, in the simplest case depending on the current direction different resistance or for more complex replicas a number of RC networks in series and also in series with again a depending on the current direction different resistance. In principle, the component values of all RC networks can also be designed differently for different current directions. The replica can go from models of a cell to models for whole battery modules or -Packs. On a specific selection of the components in the electrical equivalent circuit diagram of the battery model and the mentioned corresponding determination of the component values, i.

This behavior is illustrated schematically in FIG. 2 as a hysteresis-like waveform of the voltage-the upper curve representing the conditions of the charging process and the lower curve that of the discharging process-over the load condition. In the model, a distinction must be made between the current direction and the values used to calculate the DC output voltage. 164) 3-2012
