[0030] The application will be described in greater detail with reference to specific embodiments. The following embodiments are presented by way of example only and are not intended to limit the application in any form. It should be noted that, for those of ordinary skill in the art, without departing from the concept of the application, a number of modifications and improvements can be made. These all belong to the protection scope of the application.

[0031] It should be understood that when used in the specification and appended claims of the present application, the term "comprising" indicates the presence of described features, integers, steps, operations, elements, and / or components, but does not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof.

[0033] In the description of the specification and the appended claims of the present application, the terms "first", "second", "third", etc. are only used for differentiation and cannot be understood as indicating or implying relative importance.

[0034] In the description of the specification and the appended claims of the present application, the reference "one embodiment" or "some embodiments" means that the specific features, structures or characteristics described in connection with the embodiment are included in one or more embodiments of the present application. Therefore, the statements "in one embodiment", "in some embodiments", "in other some embodiments", "in further some embodiments" and the like appearing in different places in the specification are not necessarily all referring to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized. The terms "including", "containing", "having" and their variants mean "including but not limited to", unless otherwise specifically emphasized.

[0035] In addition, "a plurality of" mentioned in the embodiments of the present application should be interpreted as two or more.

[0036] In the current vehicle damage assessment and claim settlement process of new energy vehicles, no link collects the battery pack data of the vehicle and assesses the damage of the battery pack. The damage assessor does not know the internal failure of the battery pack and cannot master the actual situation of the damage of the battery pack, resulting in inaccurate damage assessment of the battery pack, which further leads to excessive compensation and expansion of the loss.

[0037] Based on the above problems, the embodiments of the present application determine whether the battery pack is damaged according to the battery data of the battery pack and the corresponding preset conditions, and output different claim settlement information when the battery pack is damaged and not damaged.

[0038] Figure 1 FIG. 1 is a flowchart of a method for determining loss and claim of a vehicle battery pack according to an embodiment of the present application.

[0039] As shown in FIG. 1, the method according to an embodiment of the present application can include the following steps. Figure 1

[0040] Step 101: Obtain a plurality of battery data of a battery pack of a vehicle.

[0041] The battery data represents the state of the battery pack. The plurality of battery data of the battery pack can be obtained by connecting a vehicle detection device to a battery pack special interface and positive and negative poles of the battery pack.

[0042] Step 102: Determine whether the battery pack is damaged according to each battery data and a corresponding preset condition.

[0043] The battery pack includes a plurality of battery pack monomers. Each battery data is a state of charge (SOC) of the battery pack, a state of health (SOH) of the battery pack, a number of times of charging and discharging, a temperature of the battery pack, a voltage of the battery pack, a temperature of each battery pack monomer, and a voltage of each battery pack monomer.

[0044] In one possible implementation, step 102 can specifically include the following steps.

[0045] S1: Determine whether each battery data satisfies a corresponding preset condition.

[0046] S2: If any of the above battery data satisfies the corresponding preset condition, determine that the battery pack is damaged.

[0047] Optionally, S1 can specifically include the following steps.

[0048] Determine whether the state of charge is less than a preset state of charge. Determine whether the state of health is less than a preset state of health. Determine whether the number of times of charging and discharging is greater than a preset number of times of charging and discharging. Determine whether the temperature of the battery pack is outside a preset temperature range. Determine whether the voltage of the battery pack is outside a preset voltage range.

[0049] Determine a battery pack monomer whose temperature is within a preset monomer temperature range as a first battery pack monomer, and determine a battery pack monomer whose voltage is within a preset monomer voltage range as a second battery pack monomer.

[0050] Determine whether a first ratio of the number of the first battery pack monomers to the number of all battery pack monomers is less than a first preset ratio. Determine whether a second ratio of the number of the second battery pack monomers to the number of all battery pack monomers is less than a second preset ratio. ​

[0051] For example, the preset temperature range is a normal temperature range of the battery pack, and the preset voltage range is a normal voltage range of the battery pack.

[0052] Optionally, the preset single battery temperature range is a normal temperature range of the single battery of the battery pack, and the first ratio is a proportion of the single battery of the battery pack in the normal temperature range to all single batteries of the battery pack. The preset single battery voltage range is a normal voltage range of the single battery of the battery pack, and the second ratio is a proportion of the single battery of the battery pack in the normal voltage range to all single batteries of the battery pack. If the determination result of any one of the seven determinations is yes, that is, the battery data corresponding to the any one determination satisfies the corresponding preset condition, it is determined that the battery pack is damaged.

[0053] In step 103, if the battery pack is damaged, compensation information for replacing the entire battery pack is output.

[0054] In step 104, if the battery pack is not damaged, single battery data of the battery pack is obtained, and compensation information for replacing damaged single batteries in the battery pack is output according to the single battery data of the battery pack.

[0055] In a possible implementation, in step 104, the compensation information for replacing the damaged single batteries in the battery pack is output according to the single battery data of the battery pack, and specifically can include:

[0056] According to the state data of each single battery, the damaged single battery is determined.

[0057] The compensation information for replacing the damaged single batteries in the battery pack and the corresponding numbers of the damaged single batteries are output.

[0058] Optionally, the single battery data is used to indicate whether the single battery is damaged, and the single battery data includes the state data of each single battery. According to the state data of each single battery, whether the single battery is damaged can be determined, and the numbers of the damaged single batteries are output together with the compensation information for replacing the damaged single batteries in the battery pack, so that the staff can replace and repair the damaged single batteries in the battery pack according to the numbers of the damaged single batteries.

[0059] In a possible implementation, in order to further determine the loss of the battery pack and better repair and process the replaced battery pack, the residual value of the battery pack can also be estimated. Specifically, the vehicle battery pack loss determination and compensation method provided by the embodiment of the application can further include:

[0060] In step 105, a residual value ratio is determined according to the plurality of battery data.

[0061] In step 106, the residual value of the battery pack is determined according to the residual value ratio.

[0062] Optionally, the residual value ratio is determined according to the plurality of battery data, and the residual value of the battery pack is determined according to the residual value ratio.Figure 2 Step 105 may specifically include:

[0063] S11. Calculate the deviation of the battery pack temperature from the preset temperature range; calculate the deviation of the battery pack voltage from the preset voltage range.

[0064] S12. Determine whether the deviation of the battery pack temperature is greater than the preset temperature deviation, or whether the deviation of the battery pack voltage is greater than the preset voltage deviation.

[0065] S13. If so, then the residual ratio is determined to be 0.

[0066] S14. If not, calculate the first residual value ratio based on the preset initial residual value ratio, the remaining battery capacity, and the preset remaining battery capacity adjustment coefficient; if the first residual value ratio is greater than 1, correct the first residual value ratio to 1.

[0067] S15. Calculate the second residual value ratio based on the first residual value ratio, battery health, and preset battery health adjustment coefficient; when the second residual value ratio is greater than 1, correct the second residual value ratio to 1.

[0068] S16. Calculate the third residual value ratio based on the second residual value ratio, the number of charge-discharge cycles, and the preset charge-discharge cycle adjustment coefficient; when the third residual value ratio is greater than 1, correct the third residual value ratio to 1.

[0069] S17. Calculate the fourth residual value ratio based on the third residual value ratio, the first ratio, and the first preset adjustment coefficient; when the fourth residual value ratio is greater than 1, correct the fourth residual value ratio to 1.

[0070] S18. Calculate the fifth residual value ratio based on the fourth residual value ratio, the second ratio, and the second preset adjustment coefficient; when the fifth residual value ratio is greater than 1, correct the fifth residual value ratio to 1.

[0071] S19. Use the fifth residual value ratio as the residual value ratio.

[0072] For example, when the deviation of the battery pack temperature is less than or equal to a preset temperature deviation, and the deviation of the battery pack voltage is less than or equal to a preset voltage deviation, the formula for calculating the residual value ratio is:

[0073] V r1 =V r0 ×P SOC ×C SOC

[0074] In the formula, V r1 V is the first residual value ratio. r0 To preset the initial residual ratio, P SOC C represents the remaining battery power. SOC This is a preset battery remaining capacity adjustment coefficient. When V r1V r1 = 1.

[0075] V r2 = V r1 × P SOH × C SOH

[0076] V r2 is a second residual value ratio, SOH is a battery health, C sOH is a preset battery health adjustment coefficient. When V r2 > 1, V r2 = 1.

[0077] V r3 = (1 - P CN / C CN1 ) × C CN2

[0078] V r3 is a third residual value ratio, CN is a number of times of charging and discharging, C CN1 is a total number of times of charging and discharging supported by the battery pack, i.e., a rated number of times of charging and discharging, C CN2 is a preset number of times of charging and discharging adjustment coefficient. When V r3 > 1, V r3 = 1.

[0079] V r4 = r3 × P mtd × C mtd

[0080] V r4 is a fourth residual value ratio, mtd is a first ratio, i.e., a proportion of the battery pack cells within a normal temperature range to all battery pack cells, C mtd is a first preset adjustment coefficient. When V r4 > 1, V r4 = 1.

[0081] V r5 = r4 × P mvd × C mvd

[0082] V r5 is a fifth residual value ratio, mvd is a second ratio, i.e., a proportion of the battery pack cells within a normal voltage range to all battery pack cells, C mvd is a second preset adjustment coefficient. When V r5 > 1, V r5 = 1.r5 as the residual value ratio V r .

[0083] For example, the preset adjustment coefficient, the preset temperature deviation value and the preset voltage deviation value can be set according to the brand and model of the corresponding battery pack, and are related to the brand and model of the corresponding battery, that is, the preset adjustment coefficient, the preset temperature deviation value and the preset voltage deviation value of the battery pack of different brands and models are different.

[0084] Optionally, in step 106, the residual value ratio and the preset market value can be multiplied to obtain the residual value of the battery pack.

[0085] For example, the residual value estimation formula of the battery pack is:

[0086] V = V r × V p

[0087] In the formula, V is the residual value of the battery pack, V r is the residual value ratio, and V p is the preset market value. The preset market value is the market price of the corresponding battery pack, and the market prices of battery packs of different brands and models are different.

[0088] According to the plurality of battery data of the battery pack and the corresponding preset adjustment parameters, the residual value ratio of the battery pack can be accurately obtained, and then the residual value of the battery pack can be accurately estimated according to the residual value ratio of the battery pack and the preset market value, so that the staff can repair or process the replaced battery pack according to the residual value ratio of the battery pack.

[0089] The vehicle battery pack damage estimation and claim settlement method provided by the embodiment of the application can accurately determine whether the battery pack is damaged according to the battery data of the battery pack and the corresponding preset conditions, and output different claim settlement information when the battery pack is damaged or not damaged, so that accurate damage estimation of the battery pack can be performed, and then a reasonable claim settlement mode can be provided according to the damage estimation of the battery pack, so as to avoid excessive compensation. At the same time, the residual value of the battery pack can be accurately estimated according to the battery data and the preset adjustment coefficient.

[0090] It should be understood that the size of the serial number of each step in the above embodiment does not mean the order of execution, and the execution order of each process should be determined according to its function and inherent logic, and should not constitute any limitation on the implementation process of the embodiment of the application.
