This process involves charging and discharging the battery to simulate the actual use situation, while monitoring the battery's performance indicators, such as voltage, current, etc., to evaluate the battery's health and service life. During the test, the energy-saving aging equipment recycles the discharged electrical energy to ensure that energy consumption is reduced during the battery pack aging test, thereby improving the energy-saving effect of the battery pack energy-saving aging.

[0073] In one embodiment, Figure 1 As shown, a battery pack energy-saving aging test method is provided, and the method is applied to a terminal as an example for explanation, including the following steps:

[0075] In this embodiment, the terminal responds to the staff's information upload operation to obtain the aging test requirements for the battery pack and the charging and discharging process of the battery pack, wherein the aging test requirements of the battery pack include the charging test requirements and the discharging test requirements of each aging test type, and the aging test types include overcharge and over-discharge test requirements, cycle life test requirements, capacity retention test requirements, internal resistance test requirements, high temperature accelerated life test requirements, electrochemical impedance spectroscopy (EIS) test requirements, dynamic load test requirements, etc. Among them, the charging and discharging process of the battery pack is the electric energy conversion process corresponding to the battery pack in different charging / discharging modes. The charging mode includes a constant voltage charging and discharging mode, a constant current charging and discharging mode, a constant resistance charging and discharging mode, etc. Among them, each charging and discharging mode corresponds to a current input / output range and a voltage input / output range. To adapt to each aging test requirement, the current input / output range and the voltage input / output range corresponding to each charging and discharging mode are the maximum ranges under theoretical conditions. Afterwards, the terminal identifies the current battery status of each battery pack through the battery detection mode. The battery status includes but is not limited to the remaining power, the current actual maximum capacity, and the current capacity range. Finally, the terminal identifies the charge and discharge test information of each aging test type of the battery pack based on the aging test requirements of the battery pack. Among them, each charge and discharge test information includes charge and discharge restriction conditions, sub-charge and discharge ranges in each charge and discharge mode, and battery pack status requirement information of each aging test type. Among them, the charge and discharge restriction conditions are the current limit information of charge and discharge, and the voltage limit information, wherein the current limit information includes the minimum current limit information, the maximum current limit information, or the current fluctuation range limit information. The voltage limit information includes the minimum voltage limit information, the maximum voltage limit information, or the voltage fluctuation range limit information, etc. The state requirement of each battery pack includes the maximum upper limit of the battery pack for each aging test requirement, the required remaining capacity of each battery pack, and the required working state of each battery pack.

[0077] In this embodiment, the terminal identifies the charge and discharge range of the battery pack based on the charge and discharge process of the battery pack, and generates a collaborative energy cycle test strategy for each aging test type and battery pack pre-preparation information for each aging test type based on the charge and discharge test information of each aging test type and the charge and discharge range of the battery pack. Among them, the collaborative energy cycle test strategy is an energy cycle input and output strategy between each battery pack of each aging test type, wherein the energy cycle input and output strategy includes a transmission method in which each battery pack performs sequential energy transmission in a specific order, and the last battery pack in the specific order transmits the energy of the last battery pack to the first battery pack through a current circulation strategy. The specific generation process will be described in detail later.

[0078] Step S103 , randomly selecting a target aging test type among various aging test types, and adjusting the current battery state of each battery pack based on the battery pack pre-preparation information of the target aging test type to obtain each pre-test battery pack of the target aging test type.

[0079] In this embodiment, the terminal randomly selects the target aging test type from each aging test type, and adjusts the current battery state of each battery pack based on the pre-prepared information of the battery pack of the target aging test type to obtain each pre-tested battery pack of the target aging test type. The specific adjustment process will be described in detail later, wherein this scheme selects the first target aging test type by random screening, or determines the first target aging test type by a method preset by the staff.

[0080] Step S104, based on the coordinated energy cycle test strategy of the target aging test type, perform energy-saving aging test processing on each pre-test battery pack to obtain the test result of the target aging test type and the new battery state of each battery pack, and screen the new target aging test type based on the new battery state of each battery pack and the pre-preparation information of the battery pack of each selected aging test type.

[0081] In this embodiment, the terminal performs energy-saving aging test processing on each pre-tested battery pack based on the coordinated energy cycle test strategy of the target aging test type, obtains the test results of the target aging test type and the new battery state of each battery pack, and screens the new target aging test type based on the new battery state of each battery pack and the pre-prepared information of the battery pack for each aging test type to be selected. Among them, the principle of screening the new target aging test type is to screen the aging test type to be selected corresponding to the pre-prepared information of the battery pack with the smallest adjustment degree of each new battery state as the new target aging test type. The specific screening process will be described in detail later.

[0082] Step S105, replace the battery status of each battery group with the new battery status of each battery group, and replace the target aging test type with the new target aging test type, return to execute the battery group pre-preparation information based on the target aging test type, adjust the current battery status of each battery group, and obtain the pre-test battery group steps of the target aging test type until the test results of all aging test types are obtained.

[0083] In this embodiment, the terminal replaces the battery status of each battery group with the new battery status of each battery group, and replaces the target aging test type with the new target aging test type, returns to execute the battery group pre-preparation information based on the target aging test type, adjusts the current battery status of each battery group, and obtains the pre-test battery group steps of the target aging test type until the test results of all aging test types are obtained.

[0084] Based on the above scheme, by identifying the charge and discharge test information of each aging test type and the charge and discharge range of the battery pack, a collaborative energy cycle test strategy for each aging test type is generated, so that through the collaborative energy cycle test strategy, the test process of each battery pack in the aging test type is realized by the way of electric energy cycle transmission between the battery packs, which can not only avoid the inefficiency of the aging test of a single battery pack, but also reduce the electric energy conversion process, and directly transmit electric energy to perform cycle aging tests on each battery pack, thereby reducing the amount of electric energy lost due to the conversion process. In addition, this method not only improves the efficiency of the aging test, but also through the way of electric energy cycle transmission, so that the same electric energy can be cycled to perform aging tests on multiple battery packs, greatly improving the energy-saving effect of the aging test. In addition, this scheme also uses the new battery state of each battery pack after each aging test type is tested, thereby improving the energy-saving effect of each battery pack when replacing different aging test types. Therefore, this solution not only improves the efficient testing effect of the multi-battery pack cyclic aging test, but also improves the energy-saving effect of each battery pack aging test and the energy-saving effect of the replacement execution of each aging test type, thereby comprehensively improving the energy-saving effect of the energy-saving aging test of multiple battery packs.

[0085] Optionally, based on the aging test requirements of the battery pack, the charge and discharge test information of each aging test type of the battery pack is identified, including: splitting the aging test requirements into sub-test requirements of each aging test type, and for each sub-test requirement, identifying the charging test requirements of the sub-test requirements, and the discharge test requirements of each sub-test requirement; based on the charging test requirements, identifying the battery pack status requirements of the aging test type and the charging restriction conditions of the aging test type, and based on the discharge test requirements, identifying the discharge restriction conditions of the aging test type and the discharge frequency requirements of the aging test type; using the battery pack status requirements of the aging test type and the charging restriction conditions of the aging test type as the charging test information of the aging test type, and using the discharge restriction conditions of the aging test type and the discharge frequency requirements of the aging test type as the discharge test information of the aging test type; using the charging test information of the aging test type and the discharge test information of the aging test type as the charging and discharging test information of the aging test type.

[0086] In this embodiment, the terminal splits the aging test requirement into sub-test requirements of each aging test type, and identifies the charging test requirement of each sub-test requirement and the discharging test requirement of each sub-test requirement for each sub-test requirement. The aging test requirement includes a type identifier of each aging test type, and then the terminal splits the aging test requirement into each sub-test requirement based on the type identifier. The type identifier can be a text identifier, a color identifier, a symbol identifier, etc.

[0087] Based on the charging test requirements, the terminal identifies the battery pack status requirements of the aging test type and the charging restrictions of the aging test type. Then, based on the discharge test requirements, the terminal identifies the discharge restrictions of the aging test type and the discharge frequency requirements of the aging test type. The discharge frequency requirements are the discharge frequency requirements of different aging test types, for example, the discharge frequency requirements of different load amounts corresponding to the dynamic load test requirements.

[0088] The terminal uses the battery pack state requirements of the aging test type and the charging restriction conditions of the aging test type as the charging test information of the aging test type, and uses the discharge restriction conditions of the aging test type and the discharge frequency requirements of the aging test type as the discharge test information of the aging test type. Finally, the terminal uses the charging test information of the aging test type and the discharge test information of the aging test type as the charge and discharge test information of the aging test type.

[0089] Based on the above solution, by dividing the aging test requirements into sub-test requirements of each aging test type, the charge and discharge test information of each aging test type is identified respectively, thereby improving the comprehensiveness of the analysis of each aging test type.

[0090] Optionally, based on the charge and discharge process of the battery pack, the charge and discharge range of the battery pack is identified, including: splitting the charge and discharge process of the battery pack into a charging process of the battery pack and a discharging process of the battery pack, and based on the charging process, identifying the current input range corresponding to each charging mode of the battery pack and the voltage input range corresponding to each charging mode of the battery pack; based on the discharging process, identifying the current output range corresponding to each discharging mode of the battery pack and the voltage output range corresponding to each discharging mode of the battery pack; using the current input range corresponding to each charging mode and the voltage input range corresponding to each charging mode as the charging range, and using the current output range corresponding to each discharging mode and the voltage output range corresponding to each discharging mode as the discharging range; using the charging range and the discharging range as the charge and discharge range of the battery pack.

[0091] In this embodiment, the terminal divides the charging and discharging process of the battery pack into the charging process of the battery pack and the discharging process of the battery pack, and identifies the current input range corresponding to each charging mode of the battery pack and the voltage input range corresponding to each charging mode of the battery pack based on the charging process. The current input range and voltage input range corresponding to each charging mode are different, and the current variation range and voltage variation range are different during the charging process of different charging modes.

[0092] Based on the discharge process, the terminal identifies the current output range corresponding to each discharge mode of the battery pack and the voltage output range corresponding to each discharge mode of the battery pack. The current input range and voltage input range corresponding to each discharge mode of the discharge process are different, and the current / voltage change range during the discharge process is different.

[0093] The terminal uses the current input range corresponding to each charging mode and the voltage input range corresponding to each charging mode as the charging range, and uses the current output range corresponding to each discharging mode and the voltage output range corresponding to each discharging mode as the discharging range. Finally, the terminal uses the charging range and the discharging range as the charging and discharging range of the battery pack.

[0094] Based on the above solution, the charging process and discharging process of the battery pack are split and identified, thereby improving the comprehensiveness and granularity of identification.

[0095] Optionally, based on the charge and discharge test information of each aging test type and the charge and discharge range of the battery pack, a collaborative energy cycle test strategy for each aging test type and battery pack pre-preparation information for each aging test type are generated, including: for each aging test type, based on the charging restriction conditions of the aging test type and the sub-charging ranges corresponding to the various charging methods of the battery pack, identifying the interactive charging process of each battery pack corresponding to the aging test type, and based on the battery pack status requirements of the aging test type, identifying the battery pack pre-preparation information of the aging test type; based on the discharge test information of the aging test type and the sub-discharge ranges corresponding to the various discharge methods of the battery pack, identifying the interactive discharge process of each battery pack corresponding to the aging test type and the current cycle strategy of the aging test type, and determining the collaborative energy cycle test strategy of the aging test type based on the interactive charging process of each battery pack corresponding to the aging test type, the interactive discharge process of each battery pack corresponding to the aging test type, and the current cycle strategy of the aging test type.

[0096] In this embodiment, for each aging test type, the terminal identifies the interactive charging process of each battery pack corresponding to the aging test type based on the charging restriction conditions of the aging test type and the sub-charging ranges corresponding to each charging mode of the battery pack, and identifies the pre-preparation information of the battery pack of the aging test type based on the battery pack state requirements of the aging test type. Among them, the interactive charging process is the current transmission process between each battery pack. Since the current / voltage corresponding to the charging mode of the battery pack is different from the current / voltage corresponding to the discharge mode of the battery pack, it is impossible to realize the charge and discharge cycle process of each battery pack by directly connecting the battery packs end to end. Therefore, a charge and discharge regulating device is added between each battery pack to ensure that the current / voltage output by each battery pack is adjusted before being input into another battery pack. Among them, since this method only changes the current / voltage value, not the energy conversion process, this method has extremely small loss of electric energy and is far lower than the electric energy loss value corresponding to the electric energy conversion.

[0097] Based on the discharge test information of the aging test type and the sub-discharge ranges corresponding to the discharge modes of the battery packs, the terminal identifies the interactive discharge process of each battery pack corresponding to the aging test type and the current circulation strategy of the aging test type. Among them, the current circulation strategy is to balance the input ratio value between the circulation current and the current of the grid input battery pack when the last battery pack circulates the electric energy to the first battery pack, so as to ensure that each battery pack can carry out the normal aging test process while ensuring the circulation of electric energy.

[0098] Based on the interactive charging process of each battery pack corresponding to the aging test type, the interactive discharging process of each battery pack corresponding to the aging test type, and the current cycling strategy of the aging test type, a collaborative energy cycling test strategy of the aging test type is determined.

[0099] Based on the above scheme, a coordinated energy cycle test strategy is adopted to ensure that each battery pack can undergo aging test at the same time, and the energy-saving effect of the aging test is improved.

[0100] Optionally, based on the collaborative energy cycle test strategy of the target aging test type, each pre-test battery pack is subjected to an energy-saving aging test to obtain the test result of the target aging test type and the new battery state of each battery pack, including: based on the interactive charging process of each battery pack corresponding to the target aging test type, identifying the required number of battery packs of the target aging test type, and dividing each battery pack based on the battery pack demand data to obtain each charging group; for each charging group, randomly generating a charging progressive sequence of the charging group, and based on the interactive charging process of each battery pack corresponding to the target aging test type, identifying the charging mode of each battery group and the charging start condition of each battery group; based on the interactive discharge process of each battery group corresponding to the target aging test type, Identify the discharge mode of each battery group, and generate an electric energy interactive conversion regulation strategy between each battery group based on the charging progressive sequence, the charging mode of each battery group, the charging start condition of each battery group, and the discharge mode of each battery group; identify the current circulation strategy between the last battery group in the charging progressive sequence and the first battery group in the charging progressive sequence based on the current circulation strategy, charging mode, and charging start condition of the target aging test type; based on the interactive charging process of each battery group and the interactive discharging process of each battery group, perform aging test processing on each battery group according to the charging progressive sequence through each electric energy interactive conversion regulation strategy and current circulation strategy to obtain the test result of the target aging test type and the new battery state of each battery group.

[0101] In this embodiment, the terminal identifies the required number of battery packs of the target aging test type based on the interactive charging process of each battery pack corresponding to the target aging test type, and divides and processes each battery pack based on the battery pack demand data to obtain each charging group. Among them, since different aging test types correspond to different charging and discharging methods, and when the charging and discharging methods are different, too many battery packs will affect the control efficiency and control accuracy of charging and discharging. For example, when the battery pack is subjected to a load test type, due to the change in load, the input / output current value and the input / output voltage value need to be changed efficiently and frequently. In the iterative process, the response of the battery pack in the rear position is affected by the current transmission of the battery pack in the front position. Therefore, limiting a specific number can ensure the response timeliness while improving the simultaneous training effect of multiple battery packs.

[0102] For each charging group, a charging progressive sequence of the charging group is randomly generated, and based on the interactive charging process of each battery group corresponding to the target aging test type, the charging method of each battery group and the charging start condition of each battery group are identified. Among them, the charging start condition is the input control condition when inputting the power of each battery group. When the input control condition is met, the terminal controls the power input to the battery group.

[0103] The terminal identifies the discharge mode of each battery group based on the interactive discharge process of each battery group corresponding to the target aging test type, and generates an electric energy interactive conversion regulation strategy between each battery group based on the charging progressive sequence, the charging mode of each battery group, the charging start condition of each battery group, and the discharge mode of each battery group. Among them, the interactive conversion regulation strategy is the regulation strategy of the charge and discharge regulation device. Then, the terminal identifies the current circulation strategy between the last battery group in the charging progressive sequence and the first battery group in the charging progressive sequence based on the current circulation strategy, charging mode, and charging start condition of the target aging test type. The current circulation strategy is the input ratio value between the balanced circulation current and the current of the power grid input battery group when the last battery group circulates electric energy to the first battery group.

[0104] Finally, based on the interactive charging process and the interactive discharging process of each battery group, the terminal performs aging test on each battery group according to the charging progressive sequence through each electric energy interactive conversion adjustment strategy and the current circulation strategy to obtain the test results of the target aging test type and the new battery status of each battery group.

[0105] Based on the above scheme, by adjusting the number of battery packs corresponding to each aging test type and determining the interactive conversion adjustment strategy and current circulation strategy between different battery packs, the aging test is performed, thereby improving the accuracy and comprehensiveness of the aging test.

[0106] Optionally, based on the new battery status of each battery pack and the pre-preparation information of the battery pack for each aging test type to be selected, a new target aging test type is screened, including: identifying the new battery status of each battery pack and adjusting to the average adjustment amount of the pre-preparation information of the battery pack for each aging test type to be selected; and screening the aging test type to be selected corresponding to the lowest average adjustment amount as the new target aging test type.

[0107] In this embodiment, the terminal identifies the new battery state of each battery pack and adjusts it to the average adjustment amount of the pre-prepared information of the battery pack for each aging test type to be selected. The average adjustment amount includes the average adjustment amount of the capacity and the adjustment amount corresponding to the state adjustment information of the maximum battery operating state. The adjustment amount corresponding to the state adjustment information is the state arrangement order of each battery working state preset by the terminal, wherein the state arrangement order is adjusted from short to long according to the state adjustment time to obtain the arrangement order. The number of interval working states between the arrangement orders is the adjustment amount corresponding to the filling adjustment information. Finally, the terminal selects the aging test type to be selected corresponding to the lowest average adjustment amount as the new target aging test type.

[0108] Based on the above scheme, through the new battery status of each battery pack after each aging test type is tested, a new target aging test model with the minimum battery pack pre-preparation information that needs to be adjusted for each battery pack is screened, thereby improving the energy saving effect of each battery pack when replacing and executing different aging test types.
