Description

P133057NL00
Title: System and method for controlling a battery pack
FIELD
The invention relates to systems and methods for controlling a battery pack for powering an electric drive, particularly to a modular battery pack and control methods therefor.
BACKGROUND
Battery packs for powering electric vehicles generally include a set battery cells, which are spatially arranged and electrically interconnected to provide the battery pack with a desired shape and power characteristics. A control unit is typically arranged for controlling various functions of the battery pack, such as a temperature and/or its maximum output power when the battery pack is connected to a load.
The control unit may be configured to determine a state of charge of the battery pack to control the battery pack accordingly, and to inform a user on the level of charge of the battery pack relative to its capacity.
Traditional approaches to state of charge estimation, involve open-circuit voltage measurements and Coulomb counting. More modern methods are model-based and obtain an estimate of the state of charge algorithmically from a dynamic model of the battery pack, such as by Kalman filtering. The dynamic model is typically an electrical equivalent circuit model of the battery pack. While electrochemical processes based models may provide a more accurate description of the battery pack cells, they are often too computationally demanding for real-time application in a battery pack.
Equivalent circuit models however, have some disadvantages. Model parameter estimation for the equivalent circuit models is for example not straightforward, and may result in initial modeling errors. Furthermore, the modeling error may increase over time, as the electrodynamics of the battery pack may change over time, depending on the particular usage of the battery pack.
SUMMARY
It is an aim to provide a method and system for controlling a battery system, particularly a modular battery system. It is more particularly an aim to provide an accurate estimation of a state of health of a battery pack, and/or of a state of charge of the battery pack. In a more general sense it is an object to overcome or ameliorate at least one of the disadvantages of the prior art, or at least provide alternative processes and structures that are more effective than the prior art. At any rate it is at the very least aimed to offering a useful choice and contribution to the existing art.
According to an aspect, a method for controlling a battery pack is provided. The method comprises obtaining, by a processing unit, usage data representative of usage of the battery pack and/or usage of one or more further battery packs; determining, by the processing unit, updated control parameters based on the obtained usage data; transmitting the updated control parameters over a long range link from the processing unit to the battery pack; and controlling the battery pack, by a control unit of the battery pack, based on the updated control parameters. The battery pack can be used for storing electric power, e.g. for powering an electric drive, e.g. of a vehicle.
The electrochemical dynamics of the battery pack may change over time, for example depending on how the battery pack is used. The method may accordingly account for these dynamics changes, without having to implement computationally heavy models, and dedicated expensive hardware therefor, on the battery pack. The battery pack and/or the one or more further battery packs may for example transmit, e.g. wirelessly, the usage data to the processing unit. The processing unit may be remote from the battery pack. At the processing unit, more sophisticated and computationally demanding models can be used to determine a change of a state of health of the battery pack, based on the usage data of the battery pack and insights obtained therefrom and/or from other resources.
The updated control parameters may be determined based only on the usage data from the battery pack. Usage data of the battery pack itself may however not be required for the determination of the updated control parameters. The updated control parameters may instead be determined based on the usage data from the one or more further battery packs. A change in the electrodynamics of the battery pack may for example be inferred from the usage data of the one or more further battery packs, and the updated control parameters for the battery pack may be determined accordingly. The updated control parameters may particularly be determined based on the usage data of a plurality of battery packs, optionally including the battery pack itself. The method may hence include obtaining data from a plurality of battery packs, optionally including the battery pack. The usage data from the plurality of battery packs can be used to improve models and algorithms, e.g. by the processing unit, for determining the updated control parameters for each individual battery pack.
The updated control parameters may be pack-specific. Hence, based on the usage data from the battery pack and/or the one or more further battery packs, pack-specific updated control parameters may be determined for use in controlling the battery pack.
The usage data is representative of a usage of a battery pack, and provides information on the circumstances of use of the battery pack. The usage data for example provides information on how, when, where, how long, and what for the battery pack is used and under what environmental conditions. The usage data may be acquired from, or determined based on, sensor data from sensors. The sensors may be part of the battery pack, one or more further battery packs and/or other devices such as the coupled electric drive or charger. The sensor data may for example include information on charge- and discharge cycles, in- and output powers, operating and ambient temperatures etc.
The battery pack and/or the one or more further battery packs may send the usage data with a communication unit to the processing unit. The communication unit may be configured to communicate wirelessly and/or wiredly over a long range link. The communication unit may additionally or alternatively be configured to communicate wirelessly and/or wiredly over a short rang link. The battery pack may receive, e.g. with the communication unit, e.g. over the long range link, the updated control parameters from the processing unit. The battery pack may for example store the update control parameters in a memory, e.g. by overwriting the currently stored equivalent control parameters, and control the battery pack based on the updated control parameters.
It will be appreciated that the processing unit may be at a geographically remote location from the battery pack. The updated control parameters determined by the processing unit may particularly account for a usage-dependent change in electrodynamics of the battery pack, and hence allow the control unit to optimally control the battery pack in conformity with the usage of the battery pack.
A battery pack may for example be provided comprising a set of battery cells, and a control unit that includes a wireless communication unit for wireless long range communication, and a memory configured to store control parameters. The control unit may be configured for controlling the battery pack based on the control parameters stored in the memory. The control parameters may be updated dependent on the usage of the battery pack and/or based on usage of the one or more further battery packs. The control unit may record the usage data of the battery pack, e.g. from sensors of the battery pack, and transmit the usage data, with the wireless communication unit, over the long range link, to the processing unit. The control unit may, e.g. in return, receive, with the wireless communication unit, over the long range link, the updated control parameters from the processing unit. 5 The usage data may be obtained with various sensors. The usage data may for example be obtained from sensors of the battery pack, and optionally includes one or more of charge- and discharge-cycle information, temperature information regarding the battery cells and/or the battery pack environment, mechanical stress information, geographical information. The usage data can more generally include e.g. measured by sensors, a current, a voltage, an impedance, an inductance, a capacitance, a temperature, a humidity, an electric power, for example as a function of time.
The control unit of the battery pack may for example determine various battery pack state parameters, based on the updated control parameters and sensor data obtained from the various sensors, including one or more a state of heath, a state of function, a state of charge, a state of power, a state of energy, and depth of charge, and may communicate those state parameters to a user of the battery pack. The control unit may also control various battery pack variables based on the control parameters and sensor data obtained from various sensors, such as an discharge power and a charge power, a temperature, charge balance between the battery cells and/or between battery modules, etc. The memory may for example store an equivalent circuit model representative of the electrodynamics of the battery pack, or parts thereof.
Optionally, the control parameters include model parameters of a model of the battery pack. The control parameters may for instance include model parameters for an equivalent circuit model of the battery pack, or parts thereof, stored in the memory, e.g. algorithm parameters, model structure parameters, impendence parameters, inductance parameters, and capacitance parameters.
Optionally, the control parameters include a usage constraint.
Based on the recorded usage of the battery pack, and the determined associated change in the state of health of the battery pack, it may be preferred to bound or inhibit a particular use of the battery pack. For example, when the state of health of a battery pack deteriorates over time due to a particular use or misuse of the battery pack, the processing unit may send a usage constraint to the battery pack, to limit particular functionalities of the battery pack, e.g. for safety reasons or for optimizing the Lifetime of the battery pack. The usage constraint for example bounds the charging and/or discharging power of the battery pack, particularly depending of the state of health of the battery pack.
Optionally, the battery pack includes a plurality of electrically interconnected battery modules, wherein each battery module has a module housing holding a subset of the set of battery cells. Optionally, the one or more further battery packs includes a plurality of electrically interconnected battery modules, wherein each battery module has a module housing holding a subset of the set of battery cells. The battery pack and the one or more further battery packs may both be modular, and may be based on the same or similar battery module.
Optionally, the updated control parameters are module-specific, wherein the battery modules are controlled based on the respective module- specific control parameters. Each battery module may hence be controlled respectively based on module-specific control parameters. Battery modules may evolve and wear independent from each other, for example due to small physical differences originating from manufacturing, as well as due to different loading conditions between the modules. Operating temperatures of the different battery modules may for example vary depending on the relative spatial arrangement of the modules. Battery modules at a periphery of the battery pack may for example operate at different temperatures than centrally located battery modules. The module-specific updated control parameters may hence account for such differences between the battery modules of the battery pack. It will be appreciated that the module-specific control parameters may also be pack-specific. The battery pack may hence receive updated control parameters, that are adapted to each of its battery modules.
Optionally, the usage data includes module-specific usage data representative of usage of each battery module respectively, wherein the, e.g. module-specific, updated control parameters are determined based on the module specific usage data. The module-specific usage data may be from the battery pack and/or from the one or more further battery packs. Hence, usage of the individual modules can be monitored, and a control strategy for the modular battery pack may be adapted accordingly. The module-specific usage data may expose differences in usage between the battery modules of a battery pack and/or the one or more further battery packs, and the updated control parameters may be determined to account for that. The module-specific usage data may for example be wirelessly transmitted, e.g. with the wireless communication unit, over the long range link to the processing unit. The processing unit may determine, based on the module- specific usage data, a change in a state of health for each battery module.
The processing unit may for example determine module-specific control parameters, and send the module-specific control parameters to the battery pack. It will be appreciated that the updated control parameters for the battery pack may be determined based on the module-specific usage data of the battery pack and/or on module-specific usage data of the one or more further battery packs.
The processing unit may more particularly determine a change in a state of health of individual battery cells, and/or individual clusters of battery cells within each battery module, e.g. based on the module-specific usage data.
Optionally, the usage data includes cell cluster-specific or cell- specific usage data representative of usage of individual cells or cell clusters of a battery module. Hence, the usage-data may be specific to a level of individual cell clusters or individual cells of the battery module. Optionally, updated control parameters are cell cluster-specific and/or cell-specific.
Hence, each battery module may be controlled, e.g. with a module controller, on a level of the individual cell-clusters or individual cells within the battery module. The processing unit may for example determine a change in a state of health of individual battery cells, and/or individual clusters of battery cells within each battery module, e.g. based on the cell cluster-specific and/or cell-specific usage data. The cell cluster-specific and/or cell-specific updated control parameters may for example be determined based on the cell cluster-specific and/or cell-specific usage data.
Optionally, the control unit includes a plurality of module controllers each configured for controlling a respective one of the battery modules, wherein the method comprises controlling the battery modules with the respective module controllers based on the respective module- specific control parameters. Each module controller may for example have an associated memory, storing a module-specific equivalent circuit model of the respective battery module with associated module-specific parameters.
Each module controller may record the module-specific usage data for its associated battery module.
Optionally, the method comprises recording, with the respective module controllers, module-specific usage data.
Optionally, the control unit includes a pack controller communicatively connected via the long range link to the processing unit, and communicatively connected via a short range link to each of the plurality of module controllers. It will be appreciated that the short range link can be used for internal communications over short distances, e.g. in the order of meters, between components of the battery pack, and that the long range link can be used for external communications over large distances, e.g. in the order of kilometers, with geographically remote external stations. Communications of the short range link may be transmitted according to a short range communication protocol, whereas communications over the long range link may be transmitted according to a long range communication protocol.
Optionally, the method comprises transmitting, over the short range link, the module-specific control parameters to the respective battery modules.
Optionally, the method comprises receiving, by the pack controller, the updated module-specific control parameters over the long range link, and transmitting, over the short range link, the updated module-specific control parameters from the pack controller to the respective battery modules. The pack controller may collect the module-specific usage data and transmit the module-specific usage data, e.g. with a wireless communication unit, over the long range link to the processing unit. The pack controller may also receive the module-specific control parameters, e.g. with the wireless communication unit, and send the module-specific control parameters via the short range link to the respective module controllers.
Optionally, the method comprises transmitting, over the short range link, the module-specific usage data from each module controller to the pack controller, and transmitting the module-specific usage data over the long range link from the pack controller to the processing unit.
It will be appreciated that the method as described herein may be a computer-implemented method.

BRIEF DESCRIPTION OF THE DRAWINGS
Embodiments of the present invention will now be described in detail with reference to the accompanying drawings in which:
Figure 1 shows a schematic example of a battery pack; and
Figure 2 shows a schematic example of a system including the battery pack.
DETAILED DESCRIPTION
Figure 1 shows an example of a battery pack 10. The battery pack 10 is in this example modular, and includes multiple distributed electrically interconnected battery modules 11, 12, 13. Each battery module 11-13 houses a plurality of battery cells. The battery modules are in turn housed by a pack housing 19. The battery pack 10 is in this example electrically connected to an electric drive 2, such as an electromotor of an electric vehicle. The battery pack may hence be referred to as a modular or distributed battery pack 10.
The battery pack 10 comprises a pack controller 14, configured for controlling the battery pack 10. The pack controller 14 is communicatively connected to module controllers 16, 17, 18, of the battery modules 11, 12, 13 respectively, here over a short-range communication link 7. The short range link 7 may for example be a wired communication channel, such as common communication bus.
Each module controller 11-13 is here configured to control a respective battery module, based on control parameters. The control parameters are stored in a memory. Each battery module 11-13 here includes a memory, but it will be appreciated that a common memory may alternatively be used. The control parameters include, for example, a model structure and model parameters, for reflecting dynamics of a battery model.
The module controllers 16-18 may particularly control a battery module 11- 13 based on a module-specific equivalent circuit model of the battery module 11-13 and associated model parameters, stored in the memory.
The pack controller 14 includes a wireless communication unit 15 configured for communication over a long-range communication link 8 with a remote processing unit. The wireless communication unit 15 is particularly configured to send usage data representative of a use of the battery pack 10 to a remote processing unit. The remote processing unit 1s geographically remote from the battery pack 10. The usage data may for example be recorded by the individual module controllers 16-18, and sent over the short-range communication link 7 to the pack controller 14. The usage data may hence be module-specific and representative of a use of the individual battery modules 11-13. The module-specific usage data may be collected by the pack controller 14, and transmitted over the long-range link 8 to the remote processing unit, for further processing of the usage data. The long-range communication link 8 between the battery pack 10 and the remote processing unit may be established via known wireless communication standards and protocols. The usage data may for example be send to the remote processing unit at preset time intervals.
The wireless communication unit 15 is furthermore configured for receiving, e.g. in return, updated control parameters from the remote processing unit over the long-range link. The updated control parameter may for instance overwrite the control parameters stored in memory. The updated control parameters are particularly determined based on the usage data send by the battery pack 10. The updated control parameters can accordingly account for a change in the state of health of the battery pack 10, dependent on how the battery pack 10 is used. The updated control parameters are particularly module-specific. The pack controller 14 may be configured to distribute the module-specific control parameters to the respective battery modules 11-13, over the short-range link 7.
Figure 2 schematically shows a system 100 comprising the battery pack 10, here as shown in figure 1, connected over the long-range link 8 with the remote processing unit 50. Here, the system 100 comprises multiple battery packs, particularly three battery packs 10, 20, 30. The battery packs 10, 20, 30 may be used at different geographical locations and may power a different electric drives 2, 3, 4. Each battery pack 10-30 comprises a respective pack housing 19, 29, 39 holding a respective set of battery modules 11-13, 21-22, 31-33 and associated module controllers. Each battery pack 10-30 also includes a respective pack controller 14, 24, 34, and wireless communication unit 15, 25, 35.
The battery packs 10, 20, 30 are, in this example, adapted for different applications, and therefor differ from each other, e.g. in size, capacity and maximum output power. Here, the modularity of the battery packs 10, 20, 30 provides for easy adaptability and scalability in the design of the battery packs, in view of the intended application. In this example, the battery pack 20 includes less interconnected battery modules 21, 22 than battery packs 10 and 30. Here, the battery modules also vary between the different battery packs 10, 20, 30. In particular, in this example, the battery modules 31-33 are smaller in size and capacity than the battery modules 11-13 and 21-22.
The remote processing unit 50 is here configured to receive and process pack-specific usage data, and determine pack-specific updated control parameters for each battery pack 10-30 based on the collective usage data from the battery packs 10-30. The remote processing unit 50 is here particularly configured to receive and process module-specific usage data, and determine module-specific updated control parameters for each battery module 11-13, 21-22, 31-33 of each battery pack 10-30, based on the collective module-specific usage data from the battery packs 10-30. It will be appreciated that the updated control parameters, e.g. being pack- and/or module-specific, can be determined despite the mutually different configurations of the battery packs 10-30 and modules 11-13, 21-22, 31-33.
Herein, the invention is described with reference to specific examples of embodiments of the invention. It will, however, be evident that various modifications and changes may be made therein, without departing from the essence of the invention. For the purpose of clarity and a concise description features are described herein as part of the same or separate embodiments, however, alternative embodiments having combinations of all or some of the features described in these separate embodiments are also envisaged.
However, other modifications, variations, and alternatives are also possible. The specifications, drawings and examples are, accordingly, to be regarded in an illustrative sense rather than in a restrictive sense.
In the claims, any reference signs placed between parentheses shall not be construed as limiting the claim. The word ‘comprising’ does not exclude the presence of other features or steps than those listed in a claim.
Furthermore, the words ‘a’ and ‘an’ shall not be construed as limited to ‘only one’, but instead are used to mean ‘at least one’, and do not exclude a plurality. The mere fact that certain measures are recited in mutually different claims does not indicate that a combination of these measures cannot be used to an advantage.
