The present invention relates to the parameterization of an energy supply device.
A parameterizable energy supply device such as a universal voltage supply unit or a universal current supply unit frequently has a predetermined, non-adjustable output characteristic, e.g. a voltage/current output characteristic. If the energy supply device is for example designed as a universal voltage supply unit, an amplitude value of the parameterizable energy supply device output voltage can frequently be regulated but not, however, the amplitude value of the corresponding output current and thus the voltage/current output characteristic of the parameterizable energy supply device.
The task on which the present disclosure is based is that of specifying an efficient concept for the setting of a parameterizable energy supply device output characteristic.
The subject matter solves this task by means of the features of the independent claims. Examples of the principles of this disclosure constitute the subject matter of the figures, the description and the dependent claims.
According to a first aspect of the disclosure, the task is solved by a parameterizable energy supply device comprising: a communication interface for receiving parameterizing data via a communications network; and a processor which is designed to set an output characteristic of the parameterizable energy supply device on the basis of the received parameterizing data. This thereby achieves the advantage of being able to provide a parameterizable energy supply device having a configurable output characteristic.
The parameterizable energy supply device can be an electrical energy supply device such as a voltage supply unit or a current supply unit having at least one configurable output characteristic. The parameterizable energy supply device can further comprise an electronically adjustable potentiometer for setting an amplitude value of an output voltage or an output current of the parameterizable energy supply device.

If the parameterizable energy supply device 100 is configured as a voltage source, the output voltage U is set to a no-load output voltage U0 for the voltage/current output characteristic 400 in a no-load condition of the parameterizable energy supply device 100 and there is no flow of output current I. Upon the output current I increasing, the output voltage U decreases linearly at a first gradient until reaching a nominal load output voltage UNOM. When the output voltage U reaches the nominal load output voltage UNOM, the output current I has risen to a nominal load output current INOM. This state can correspond to a preferential operating state of the parameterizable energy supply device 100. If the output current I increases further, the output voltage U then decreases linearly at a second gradient, wherein the second gradient is greater than the first gradient in terms of absolute value. Upon the output current I reaching a short-circuit output current ISC, the output voltage U reaches a minimum value. E.g. the minimum value is 0.0001 V, 0.001 V, 0.01 V, 0.1 V, 1 V or 10 V. The current limitation of the output current I to the short-circuit output current ISC can correspond to a hard short circuit at which there is a flow of output current I.
The no-load output voltage U0 can correspond to an output voltage U under no-load conditions. The nominal load output voltage UNOM can further correspond to an output voltage U at nominal load. The nominal load output current INOM, can correspond to an output current limit value at nominal voltage. The short-circuit output current ISC can further correspond to an output current I in short-circuit state.
If the parameterizable energy supply device 100 is configured as a voltage source, the output voltage U is set to a no-load output voltage U0 for the voltage/current output characteristic 400 in a no-load condition of the parameterizable energy supply device 100 and there is no flow of output current I. Upon the output current I increasing, the output voltage U increases linearly at a third gradient until reaching a nominal load output voltage which can be higher than the nominal load output voltage UNOM of the voltage/current output characteristic 400. When the output voltage U reaches the nominal load output voltage, the output current I has risen to a nominal load output current which can be lower than the nominal load output current INOM of the voltage/current output characteristic 400. This state can correspond to a preferential operating state of the parameterizable energy supply device 100. If the output current I increases further, the output voltage U then decreases linearly at a fourth gradient. Upon the output current I reaching a short-circuit output current ISC, the output voltage U reaches a minimum value. E.g. the minimum value is 0.0001 V, 0.001 V, 0.01 V, 0.1 V, 1 V or 10 V. The current limitation of the output current I to the short-circuit output current ISC can correspond to a hard short circuit at which there is a flow of output current I.
According to one example, the no-load output voltage U0, the nominal load output voltage UNOM, the nominal load output current INOM, the short-circuit output current ISC and/or the respective gradient can be regulated in order to set the output characteristic.
According to a further example, output characteristic parameters of the output characteristic can be freely expanded. For example, an output current can adjustably render a voltage drop. A current limitation can furthermore be set as a function of the output voltage U.
According to a further example, a fuse mode output characteristic can correspond to the output characteristic progression of one of the voltage/current output characteristics 400, 401. If, however, the output current I exceeds a predetermined current limit value or the output voltage U falls short of a predetermined voltage limit value, the parameterizable energy supply device 100 can turn off automatically after a predetermined interval of time. A user can, for example, manually reset or switch the parameterizable energy supply device 100 back on again.
According to a further example, the parameterizable energy supply device 100 can be designed as a power source. In this case, the voltage/current output characteristics 400, 401 can likewise be progressed as described above. Only the voltages and currents need to be interchanged.
If the parameterizable energy supply device 100 is configured as a voltage source, the output voltage U is set to a no-load output voltage U0 in a no-load condition of the parameterizable energy supply device 100 and there is no flow of output current I. Upon the output current I increasing, the output voltage U decreases linearly at a first gradient until reaching a nominal load output voltage UNOM. When the output voltage U reaches the nominal load output voltage UNOM, the output current I has risen to a nominal load output current INOM. The output voltage U and the output current I decrease linearly at a second gradient as the process continues, wherein the second gradient is greater than the first gradient in terms of the absolute value. Upon the output current I reaching a short-circuit output current ISC, the output voltage U reaches a minimum value. E.g. the minimum value is 0.0001 V, 0.001 V, 0.01 V, 0.1 V, 1 V or 10 V. The current limitation of the output current I to the short-circuit output current ISC can correspond to a hard short circuit at which there is a flow of output current I.
According to one example, the nominal load output voltage UNOM can be higher than the no-load output voltage U0. In this case, upon an increase in the output current I, the output voltage U increases linearly at a further gradient from the no-load output voltage U0 until reaching the nominal load output voltage UNOM.
According to one example, the no-load output voltage U0, the nominal load output voltage UNOM, the nominal load output current INOM, the short-circuit output current ISC and/or the respective gradient can be regulated in order to set the output characteristic.
According to a further example, the parameterizable energy supply device 100 can be operated in voltage regulation until reaching the nominal load output current INOM or a current limit value. As the process continues, the parameterizable energy supply device 100 can be operated under current limitation until reaching a hard short circuit. The nominal load output current INOM or the current limit value can be reduced upon decreasing output voltage U in order to reduce cable loading upon overload.
According to a further example, the parameterizable energy supply device 100 can be designed as a power source. In this case, the foldback output characteristic 500 can likewise be progressed as described above. Only the voltages and currents need to be interchanged.
If the parameterizable energy supply device 100 is configured as a voltage source, the output voltage U is set to a no-load output voltage U0 in a no-load condition of the parameterizable energy supply device 100 and there is no flow of output current I. Upon the output current I increasing, the output voltage U decreases linearly at a first gradient until reaching a nominal load output voltage UNOM. When the output voltage U reaches the nominal load output voltage UNOM the output current I has risen to a nominal load output current INOM. As the process continues, the output voltage U decreases while the output current I remains constant at the nominal load output current INOM. Once the output voltage U drops below an output voltage threshold value UHI, the parameterizable energy supply device 100 is switched off for a first time interval tHIOFF and thereafter restarted. If no valid output variable is reached in the further course of the process after a second interval of time tHION, the restart can be aborted and then restarted again after the end of the first time interval tHIOFF. This process can be repeated if necessary.
According to one example, the nominal load output voltage UNON can be higher than the no-load output voltage U0. In this case, upon an increase of the output current I, the output voltage U increases linearly at a further gradient from the no-load output voltage U0 up to the nominal load output voltage UNOM.
According to one example, the no-load output voltage U0, the nominal load output voltage UNON, the output voltage threshold value UHI, the nominal load output current INOM, the respective gradient, the first time interval tHIOFF and/or the second time interval tHION can be regulated in order to set the output characteristic.
According to a further example, the parameterizable energy supply device 100 can be operated in voltage regulation until reaching the nominal load output current INOM or a current limit value. As the process continues, the parameterizable energy supply device 100 can be operated under voltage or current regulation until reaching a voltage limit value or a current limit value.
According to a further example, the parameterizable energy supply device 100 can be designed as a power source. In this case, the hiccup mode output characteristic 600 can likewise be progressed as described above. Only the voltages and currents need to be interchanged.
If the parameterizable energy supply device 100 is configured as a voltage source, the output voltage U is set to a no-load output voltage U0 in a no-load condition of the parameterizable energy supply device 100 and there is no flow of output current I. Upon the output current I increasing, the output voltage U decreases linearly at a predetermined gradient until reaching a nominal load output voltage UNOM. When the output voltage U reaches the nominal load output voltage UNOM, the output current I has risen to a nominal load output current NNOM. As the process continues, the output current I can increase to a dynamic output current IDYN- for one interval of time tDYN while the output voltage U remains set at the nominal load output voltage UNOM. The increase in the output current I can be discontinued as the process continues and the further progression of the output characteristic 700 with dynamic boost can correspond to that of a foldback output characteristic 500, a fuse mode output characteristic or a hiccup mode output characteristic 600.
The dynamic output current IDYN can be a time-dependent dynamic output current.
According to one example, the nominal load output voltage UNOM can be higher than the no-load output voltage U0. In this case, upon an increase in the output current I, the output voltage U increases linearly at a further gradient from the no-load output voltage U0 up to the nominal load output voltage UNOM.
According to one example, the no-load output voltage U0, the nominal load output voltage UNOM, the nominal load output current INOM, the short-circuit output current ISC, the dynamic output current IDYN, the predetermined gradient and/or the time interval tDYN can be regulated in order to set the output characteristic.
According to a further example, the parameterizable energy supply device 100 can be operated in voltage regulation until reaching the dynamic output current IDYN. After time interval tDYN, the increase in current can be reset and the output current I can be reset to the nominal load output current INOM or a current limit value. As the process continues, the further limiting procedure can correspond to that of a foldback output characteristic 500, a fuse mode output characteristic or a hiccup mode output characteristic 600.
According to a further example, the parameterizable energy supply device 100 can be designed as a power source. In this case, the output characteristic 700 with dynamic boost can be likewise progressed as described above. Only the voltages and currents need to be interchanged.
The charging characteristic 800 can be associated with a constant current and constant voltage charging procedure, such as an IUU charging procedure, for a storage medium like a lead-acid battery. In a first charging phase of the charging characteristic 800, the parameterizable energy supply device 100 charges the storage medium at a constant output current I. In order to keep the output current I constant, the output voltage U of the parameterizable energy supply device 100 is continuously increased as a function of time. Upon the output voltage U reaching a charging output voltage Ur at a first time point tIMODE, the parameterizable energy supply device 100 switches into a second charging phase at a constant output voltage U. The output voltage U is hereby set to the charging output voltage U1. The output current I decreases continuously in the second charging phase. Upon reaching the second time point tU2MODE, the parameterizable energy supply device 100 switches into a third charging phase at a lower constant output voltage U so as to hold the storage medium charge. The output voltage U is hereby set to an end-of-charge output voltage U2.
The charging output voltage U1 can be a high output voltage after the first charging phase ends or a constant current charge. Furthermore, the first charging phase or the constant current charging phase can be limited in time by the first time point tIMODE. The end-of-charge output voltage U2 can be a float voltage or an end-of-charge voltage for the continuous charging of the storage medium,
According to one example, the charging output voltage U, the end-of-charge output voltage the second time point tU2MODE and/or the time interval between time points tIMODE and tU2MODE can be regulated in order to set the output characteristic.
According to one example, the limiting procedures shown in
