Definitions
- the present invention relates to a method and to ⁇ order to determine the Ladekapazticians- of the Healthy and ⁇ reasonableness state of an electric energy storage device according to the preamble of claim 1 for the method of claim 3 or for the assembly.
- the charging capacity SOC and the state of health SOH of the battery wherein battery below always for battery as such or for energy storage as such or for battery system, that is for a Batte ⁇ rie or for an energy store with units for the control or regulation of Energyzu- and -abbowen stands are determined during operation by means of so-called ge ⁇ state estimator.
- a state estimator has deposited a given battery model as the basis for his work. This model must be adjusted to ⁇ reason of aging processes in the cells of the battery because of changes Ladekapazticians- and resistance parameters after some time. For this purpose, certain series of measurements are necessary, which are recorded by means of an external, highly accurate battery charger with measured value recording.
- Health status SOH is determined by a very slow charge and discharge cycle.
- the document DE 101 06 505 AI discloses an example of a corresponding method. Another way to determine the current charge capacity and resistance parameters of the cells is the
- Impedance meter By these measurements, the opponent ⁇ articles can be measured, and closed by correlation to the aging of the charge capacity of the battery. The effort, especially for the measuring device, is high.
- the object of the present invention is to provide a method and an arrangement for determining the charging capacity and the charging capacity
- the method according to the invention then has procedural steps according to which a measuring circuit is formed between an AC / DC converter or a DC / DC controller and a battery system connected in each case by providing on the DC side of the AC / DC converter or the A sine-shaped voltage harmonic with a varied frequency or a sinusoidal current with a varied frequency is impressed on the DC / DC controller as a respective measurement signal.
- the respective measurement Sent from the AC / DC converter or the DC / DC controller to the battery system the current response or thepossant ⁇ word determined for each measurement signal on the battery system, acting on the measuring circuit located outside of the battery system tioning capacity or impedance determined in advance ,
- Each current response or each voltage response of the effect of the predetermined capacitances or impedances adjusted, a phase difference from each adjusted current response or each adjusted voltage response determined and parameters for a statement on the charging capacity or the health ⁇ the state of the downstream battery system from the he ⁇ derived phase shifts.
- the arrangement of the invention then comprises a measurement equipment, which form a measuring circuit between ei ⁇ nesammlung on the DC side of the AC / DC converter or the DC / DC actuator under imparting a sinusoidal voltage harmonics with varied frequency or a sinusoidal current with varied frequency as a respective measurement signal which is sent to the battery system, and on the other hand connected to the Batte ⁇ riesystem under determining a current response or a voltage response to each transmitted measurement signal.
- the measuring device is designed for a pre ⁇ abbephin of acting on the loop, to exploiting Dende outside of the battery system capacities or impedances,
- the inventive process respectively the dung OF INVENTION ⁇ arrangement according to have the advantage that the Batteriemo ⁇ dell may be adjusted directly to the battery. Furthermore, from the correlation of the resistances, the health status of the battery can be assessed. This makes it possible to always have the right battery model during operation of the battery. State estimator used to work accurately and it can be difficult to calculate the healthy ⁇ integrated, state of the battery on the state estimator dispensed with. Impedance measurements are no longer performed by an external device or device integrated into the powertrain, but by the already installed AC / DC converter or DC / DC controller. The effectiveness of load capacity and health status determination is increased. The costs for this are reduced, because no maintenance and no removal of the battery or the battery ⁇ system from the current operation are more necessary.
- the battery is connected directly.
- at least one winding system of a connected motor is required.
- the inductance of the motor is needed to let the inverter generate the signals.
- the inverter sends the sinusoidal currents and varies them over a frequency spectrum.
- the voltage sensors on the inverter, on the battery system and on the cells are used to control the To measure voltage response. By measuring the cells, it is even possible to specifically measure a cell.
- the main focus is on the overall resistance of the battery system and on determining the parameters for it. From the recorded frequency spectrum, the resistors can be assigned.
- measuring device ME is not necessarily to be understood as a separate unit, independent of the rest of the components shown, although this may in principle also be the case.
- the measuring device ME is to be regarded as an integral part of the rest of the components shown, where as such already existing suitable components are shared.
- the arrangement shown in the figure shows starting from a generator G a first drive train with an AC / DC converter ADC and a first battery system BS1, wherein a second drive train via a DC / DC controller DDC and a second battery system BS2 leads.
- the respective Batteriesys ⁇ systems BS1 and BS2 are each a
- the compensation circuit resistors could also be real resistors.
- the first voltage VI first consumer VR1 and the second voltage V2 second consumer VR2 are supplied with electrical energy.
- the first te voltage is a 42 volt voltage and the second voltage is a 12v voltage.
- the battery systems BS1 and BS2 have in the present exemplary example in addition to an energy storage device such as a battery as a core component, other components that are used to measure, for example, optionally already Zellimpe ⁇ impedances.
- the batteries battery systems BS1 and BS2 where appropriate, conversely, the battery system BS1 and BS2 can actually composed only of ei ⁇ ner battery alone.
- Corresponding be ⁇ forced components to form the inventive arrangement are then supplement.
- the AC / DC converter ADC which is already prepared in the manner either or prepare that for this inverter in accordance needed to be impressed signals, in particular ⁇ sondere special measuring signals are einschleusbar.
- measuring device ME not necessarily be a separate unit, as indicated in the figure, but a total existie ⁇ -saving device which is embedded in different forms in a starting construct.
- the ge in the figure showed ⁇ figure shows only the basic principle of the inventive arrangement.
- a measuring device ME can come not only to a single one of the drive trains for a set ⁇ ⁇ gleichzei tig but them. In the latter case, it is conceivable that in fact only a single measuring device ME is installed, but in such a way that it measures alternately at intervals in each drive train.
- two battery systems BS1 and BS2 are used, which are respectively connected in a drive train, and that the first battery system BS1 together ⁇ men with an AC / DC converter ADC and the second Batteriesys ⁇ tem BS2 additionally together with a DC / DC controller DDC.
- the battery systems BS1 and BS2 are located after the fi- gur each at a the AC / DC converter ADC or DC / DC controller DDC downstream point.
