This application incorporates the entire text of the above-mentioned Chinese patent application by reference. Figure 1 Figure 2 Technical Field

[0002] The present invention relates to the technical field of cost calculation, and particularly to a method, device and medium for calculating the cost of spare batteries in a battery swapping station. Background Art

[0003] With the rapid development of the new energy vehicle industry, the charging problem of new energy vehicles needs to be solved urgently. At present, the battery swapping solution is a major measure to solve the charging problem of electric vehicles. The spare batteries are stored in the battery swapping station for charging and daily maintenance. When the electric vehicle runs out of power, the electric vehicle only needs to drive into the battery swapping station to replace the spare battery.

[0004] As one of the important assets of the battery swapping station, the cost data of the spare batteries has a very significant impact on the profit, cash flow and return on investment of the battery swapping station. Therefore, it is particularly necessary to calculate the cost of the spare batteries in the battery swapping station.

[0005] At present, the method for calculating the cost of the spare batteries in the battery swapping station mainly realizes by manually regularly counting the number of spare batteries that can be normally used in the battery swapping station and manually regularly monitoring the status of the spare batteries to understand the depreciation situation of the spare batteries. This calculation method not only requires a lot of time for manual counting and monitoring, resulting in low efficiency, but also the manual calculation of depreciation leads to the calculation result not being able to truly reflect the cost of the spare batteries in the battery swapping station. Summary of the Invention

[0006] The present invention provides a method, device and medium for calculating the cost of spare batteries in a battery swapping station, which are used to solve the following technical problems: the existing cost calculation scheme for spare batteries in a battery swapping station has low efficiency and the calculation result cannot reflect the true cost.

[0007] The present invention adopts the following technical solutions:

[0008] In the first aspect, the present invention provides a method for calculating the cost of spare batteries in a battery swapping station, the method comprising: obtaining the number of newly added batteries in the current calculation period of the battery swapping station; calculating the cost of the newly added batteries in the current calculation period through the unit price of the newly added batteries and the number of newly added batteries in the current calculation period; obtaining the total depreciation cost of the existing batteries in the current calculation period; and determining the total cost of the batteries in the current calculation period according to the cost of the newly added batteries in the current calculation period and the total depreciation cost of the existing batteries in the current calculation period.

[0009] The present invention divides the cost of spare batteries in a battery swapping station into two parts. One part is the cost brought by newly added spare batteries, which is determined by the number of newly added batteries and the unit price of the batteries. The other part is the depreciation cost of the spare batteries, so that the total cost of the spare batteries calculated can reflect the real cost. Moreover, the cost calculation process in the present invention does not require manual participation in the statistics and monitoring process, and directly conducts statistics when the newly added batteries enter the station, saving human resources, reducing labor costs, and also improving the calculation efficiency of the cost of spare batteries in the battery swapping station.

[0010] In a possible implementation manner of the present invention, obtaining the total depreciation cost of existing batteries in the current calculation period includes: calculating the depreciation cost of the newly added batteries in the historical calculation period in the current calculation period through the cost of the newly added batteries in the historical calculation period, so as to obtain the total depreciation cost in the current calculation period.

[0011] The present invention also divides multiple calculation periods when calculating the cost, calculates the total depreciation cost in the current calculation period through the depreciation cost of the newly added batteries in the historical calculation period in the current calculation period, thereby completing the calculation of the depreciation cost, and can ensure the accuracy of the calculation of the depreciation cost.

[0012] In a possible implementation manner of the present invention, the cost of the newly added batteries in the historical calculation period = the number of newly added batteries in the historical calculation period * the unit price of the newly added batteries; the historical calculation period and the current calculation period are in units of months.

[0013] The present invention calculates the cost of spare batteries in units of months, so that the spare batteries are depreciated and statistically counted in units of months, providing a basis for the accuracy of the calculation of the depreciation cost. At the same time, when calculating the depreciation cost of the newly added batteries in the historical calculation period in the current calculation period, the cost of the newly added batteries in the historical calculation period is used, and this cost is also determined by the product of the number of newly added batteries and the unit price of the newly added batteries, ensuring the reliability and effectiveness of the calculated depreciation cost.

[0014] In a possible implementation manner of the present invention, calculating the depreciation cost of the newly added batteries in the historical calculation period in the current calculation period includes: obtaining the depreciation life and depreciation tax rate of the newly added batteries; calculating the depreciation cost of the newly added batteries in the historical calculation period in the current calculation period through the cost of the newly added batteries in the historical calculation period, the depreciation life, and the depreciation tax rate.

[0015] In a possible implementation manner of the present invention, the depreciation cost of the newly added batteries in the historical calculation period in the current calculation period is calculated by the following formula: depreciation cost = the cost of the newly added batteries in the historical calculation period / depreciation life / 12 / (1 + depreciation tax rate); the depreciation life is 6, and the depreciation tax rate is 0.13.

[0016] When calculating the depreciation cost, the present invention also uses the depreciation life and depreciation tax rate corresponding to the newly added battery, which can further ensure the accuracy of the calculated depreciation cost and enable it to reflect the depreciation situation of the actual spare battery.

[0017] In a possible implementation manner of the present invention, obtaining the total depreciation cost of the current calculation period includes: calculating the sum of the depreciation costs of the newly added batteries in the historical calculation period in the current calculation period; calculating the depreciation cost of the newly added batteries in the current calculation period in the current calculation period according to the cost of the newly added batteries in the current calculation period, the depreciation life, and the depreciation tax rate; and obtaining the total depreciation cost of the current calculation period by summing the sum of the depreciation costs of the newly added batteries in the historical calculation period in the current calculation period and the depreciation cost of the newly added batteries in the current calculation period in the current calculation period.

[0018] When calculating the total depreciation cost of the current calculation period, the present invention not only calculates the sum of the depreciation costs of the newly added batteries in the historical calculation period in the current calculation period, but also calculates the depreciation cost of the newly added batteries in the current calculation period in the current calculation period. That is, when calculating the total depreciation cost, it calculates the depreciation costs of all the newly added batteries in each calculation period in units of the calculation period. In this way, not only can it ensure that no battery is missed when calculating the depreciation cost and all the depreciation costs of the batteries can be calculated, thus ensuring the accuracy of the depreciation cost calculation result, but also when calculating the depreciation cost, the same calculation formula is adopted, comprehensively considering parameters / factors such as the cost of the newly added battery, the depreciation life, and the depreciation tax rate, making the calculation process of the depreciation cost simple and practical, and also improving the calculation efficiency of the depreciation cost, thereby improving the calculation efficiency of the total cost of the spare batteries in the entire battery swapping station.

[0019] In a possible implementation manner of the present invention, the method further includes: if the current calculation period is the scrapping month of the newly added battery in the historical calculation period, the newly added battery in the historical calculation period is not included in the depreciation cost of the current calculation period.

[0020] When calculating the depreciation cost, if the current calculation period happens to be the scrapping month of the newly added battery in the historical calculation period, then when calculating the depreciation cost in the current calculation period, the scrapped battery is no longer included. This is because the depreciation cost of the scrapped battery has been calculated in the first calculation period when it was newly added, and it can be no longer calculated in the scrapping calculation period to avoid the depreciation cost of the scrapped battery being calculated multiple times, thus affecting the total depreciation cost of the current calculation period and ensuring the accuracy of the total depreciation cost calculation result.

[0021] In a possible implementation manner of the present invention, the method further includes: if the scrapping month of the newly added batteries in the current calculation period is the scrapping month of the newly added batteries in the historical calculation period, the number of newly added batteries in the current calculation period is the number of scrapped batteries in the historical calculation period.

[0022] When there are scrapped batteries in the current calculation period of the present invention, the number of scrapped batteries will be used as the number of newly added batteries for addition, so as to ensure an adequate supply of spare batteries in the battery swapping station. By balancing the two quantities, it is possible to avoid the situation of too many or too few spare batteries in the battery swapping station, so that the number of spare batteries in the battery swapping station always remains at a certain level, which is also convenient for the cyclic calculation of costs.

[0023] In a possible implementation manner of the present invention, the method further includes: determining the cumulative cost of newly added batteries in the current calculation period based on the cost of newly added batteries in the current calculation period and the cost of newly added batteries in the historical calculation period; calculating the battery rental for the current calculation period based on the cumulative cost of newly added batteries and the depreciation life of the newly added batteries.

[0024] After calculating the total battery cost in the current calculation period of the present invention, the battery rental for the current calculation period can also be calculated based on the cumulative cost of newly added batteries and the depreciation life in the current calculation period. After calculating the rental for the calculation period, the profit calculation for the battery swapping station's calculation period can be realized. While the total battery cost has a high degree of accuracy, the profit calculated based on the cost can also ensure a high degree of accuracy and authenticity, providing a reference for the operation suggestions of the battery swapping station.

[0025] In a second aspect, the present invention further provides a cost calculation device for spare batteries in a battery swapping station, including: an acquisition module that acquires the number of newly added batteries in the current calculation period of the battery swapping station; a calculation module that calculates the cost of newly added batteries in the current calculation period based on the unit price of newly added batteries and the number of newly added batteries in the current calculation period; the acquisition module that acquires the total depreciation cost of the existing batteries in the current calculation period; a determination module that determines the total battery cost in the current calculation period based on the cost of newly added batteries in the current calculation period and the total depreciation cost of the current calculation period.

[0026] In a third aspect, the present invention further provides a cost calculation device for spare batteries in a battery swapping station, where the device includes: at least one processor; and a memory communicatively connected to the at least one processor; wherein, the memory stores instructions that can be executed by the at least one processor, so that the at least one processor can execute the cost calculation method for spare batteries in a battery swapping station according to any one of the above.

[0027] In a fourth aspect, the present invention also provides a non-volatile computer storage medium, on which computer-executable instructions are stored, and the computer-executable instructions are configured to execute the cost calculation method for the spare batteries of the battery swapping station described in any one of the above.

[0028] The cost calculation method, device and medium for the spare batteries of the battery swapping station provided by the present invention have the following beneficial effects:

[0029] When calculating the total cost of the spare batteries of the battery swapping station, the present invention divides multiple calculation cycles, and calculates two parts of costs for each calculation cycle. One part is the cost of newly added batteries in the current calculation cycle, which is brought about by the newly added spare batteries in the battery swapping station, and is mainly determined by the product of the number of newly added batteries and the unit price of the batteries. The other part is the depreciation cost of the newly added batteries in the historical calculation cycle in the current calculation cycle, so as to realize the automatic calculation of the total cost of the spare batteries of the battery swapping station, avoiding the traditional process of manually participating in counting the number of batteries and monitoring the battery status to determine the battery depreciation situation, enabling the calculation process of the spare battery cost to be efficiently realized. Moreover, when calculating the depreciation cost, the calculation of the depreciation cost of the newly added batteries in different calculation cycles in the current calculation cycle is realized, ensuring the accuracy of the calculation result of the depreciation cost, so that the calculated depreciation cost can reflect the true depreciation situation or cost of the spare batteries of the battery swapping station, and thus the finally calculated spare battery cost is accurate and can reflect the true spare battery cost.

[0033] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will clearly and completely describe the technical solutions in the present invention in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of this specification, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0034] The following will explain the method in the present invention in detail through the accompanying drawings.

[0035] Figure 2 It is a flowchart of a method for calculating the cost of spare batteries in a battery swapping station provided by the present invention. As Figure 2 shown, the cost calculation method in the present invention at least includes the following execution steps:

[0036] Step 101: Obtain the number of newly added batteries in the current calculation period of the battery swapping station.

[0037] When calculating the cost of spare batteries in the battery swapping station of the present invention, multiple calculation periods are divided according to time. Taking the calculation of the total cost of spare batteries in the current calculation period as an example, an explanation will be given.

[0038] First, obtain the number of newly added batteries in the current calculation period. In the battery swapping station, the spare batteries have a certain service life or usage years. When the spare batteries reach the usage years or service life, they will be scrapped. In order to enable the normal operation of the battery swapping station, after the batteries are scrapped, the battery swapping station will introduce new spare batteries to fill the vacancies. Therefore, in the current calculation period, when the newly added spare batteries are put into storage, the quantity statistics can be carried out to obtain the number of newly added batteries in the current calculation period.

[0039] As an optional implementation manner, the aforementioned calculation period can be divided in units of months. That is, taking a month as the calculation period, calculate the cost of spare batteries in the battery swapping station every month.

[0040] Step 102: Calculate the cost of newly added batteries in the current calculation period through the unit price of newly added batteries and the number of newly added batteries in the current calculation period.

[0041] In the present invention, the cost of spare batteries in the battery swapping station is divided into two parts. One part is the cost of newly added batteries, and the other part is the cost brought by the depreciation of spare batteries.

[0042] For the cost of newly added batteries, it can be calculated by multiplying the number of newly added batteries obtained in the previous step by the unit price of the batteries. That is, multiply the number of newly added batteries in the current calculation period by the unit price of each newly added battery to obtain the cost of newly added batteries in the current calculation period.

[0043] For example, if the current calculation period is March and the swapping station newly added 32 spare batteries in March, with the unit price of each spare battery being 61,309 yuan, then the cost of the newly added batteries in the swapping station in March is 61,309 * 32 = 1,961,888 yuan.

[0044] Step 103: Obtain the total depreciation cost of the existing batteries in the current calculation period.

[0045] Regarding the cost brought by battery depreciation in the swapping station, that is, the depreciation cost of the existing batteries in the current calculation period, it needs to be calculated through the newly added batteries in the historical calculation period. It should be noted that the historical calculation period here is the calculation period before the current calculation period. For example, if the current calculation period is May, then the historical calculation periods can be March and April.

[0046] Meanwhile, the existing batteries in the swapping station are composed of the newly added batteries in the historical calculation period and the newly added batteries in the current calculation period, and at the same time, the scrapped batteries in the current calculation period need to be subtracted. Of course, after the batteries are scrapped, there is no need to calculate the depreciation cost anymore. If there are no newly added batteries in a certain historical calculation period, there are no batteries newly added in that historical calculation period in the existing batteries. Therefore, when calculating the depreciation cost of the existing batteries, the depreciation cost of the newly added batteries (with a quantity of 0) in that historical calculation period in the current calculation period is 0.

[0047] In a possible implementation manner of the present invention, the total depreciation cost in the current calculation period can be calculated through the following process:

[0048] First, calculate the depreciation cost of the newly added batteries in the historical calculation period in the current calculation period. For example, the depreciation cost of the spare batteries newly added in March and April in May.

[0049] Specifically, the cost of the newly added batteries in the historical calculation period can be calculated by multiplying the quantity of the newly added batteries obtained in the historical calculation period by the battery unit price. Here, the quantity of the newly added batteries in the historical calculation period can be counted when the newly added batteries are put into storage, which is the same as or similar to the way of obtaining the quantity of the newly added batteries in the current calculation period, and the present invention will not elaborate here.

[0050] Furthermore, each type of spare battery corresponds to different depreciation years and depreciation tax rates. When a swapping station newly adds spare batteries, the types or categories of the spare batteries will be registered. Based on the registered types or categories, the corresponding depreciation years and depreciation tax rates of the spare batteries can be determined. Of course, the depreciation years and depreciation tax rates here can also be directly obtained from the website of the spare battery manufacturer.

[0051] Further, after obtaining the new battery cost in the historical calculation period, the depreciation tax rate and the depreciation life of the backup battery, the depreciation cost of the new battery in the historical calculation period in the current calculation period can be calculated through these three parameters.

[0052] As an alternative implementation, the depreciation cost of the new battery in the historical calculation period in the current calculation period can be calculated by the following formula:

[0053] Depreciation cost = New battery cost in the historical calculation period / Depreciation life / 12 / (1 + Depreciation tax rate);

[0054] In the above formula, the depreciation life can take a value of 6, and the depreciation tax rate can take a value of 0.13.

[0055] For example, if the swapping station added 32 backup batteries in March and 14 backup batteries in April, and the unit price of each backup battery is 61,309 yuan, then the new battery cost of the swapping station in March is 61,309 * 32 = 1,961,888 yuan, and the new battery cost in April is 14 * 61,309 = 858,326 yuan. According to the above formula, with a depreciation life of 6 and a depreciation tax rate of 0.13, the depreciation cost of the backup batteries added in March at the swapping station in May can be calculated as 1,961,888 / 6 / 12 / 1.13 = 24,114 yuan, and the depreciation cost of the backup batteries added in April at the swapping station in May is 858,326 / 12 / 6 / 1.13 = 10,550 yuan.

[0056] Secondly, in a possible implementation of the present invention, to calculate the total depreciation cost of the existing batteries at the swapping station in the current calculation period, it is also necessary to consider the depreciation cost brought by the new batteries added at the swapping station in the current calculation period. This part of the depreciation cost can be calculated in the first calculation period when the backup batteries are added (i.e., starting from the month of addition), or in the second calculation period when the backup batteries are added (i.e., starting from the next month). However, if the depreciation cost is calculated in the first calculation period of the backup batteries, then the depreciation cost will not be calculated again when calculating the depreciation cost in the calculation period when the backup batteries are scrapped (i.e., in the month when the backup batteries are scrapped). This can ensure the accuracy of the calculation result of the backup battery depreciation cost and avoid double calculation of the depreciation cost.

[0057] To facilitate the explanation of the cost calculation method of the present invention, a scheme is adopted in the present invention to calculate the depreciation cost starting from the first calculation period when the spare battery is newly added. In this way, when calculating the total depreciation cost of the current calculation period, it is also necessary to consider the depreciation cost brought by the newly added spare battery in the current calculation period. The calculation of this part of the depreciation cost is the same or similar to the calculation process of the depreciation cost of the newly added battery in the historical calculation period in the current calculation period. That is, the depreciation cost of the newly added battery in the current calculation period in the current calculation period can be calculated through the cost of the newly added battery in the current calculation period, the depreciation tax rate, and the depreciation life. That is, the formula can be used: Depreciation cost = Cost of newly added battery in the current calculation period / Depreciation life / 12 / (1 + Depreciation tax rate) for calculation.

[0058] For example, if the replacement power station newly added 18 spare batteries in May, and the unit price of each spare battery is 61,309 yuan, then the cost of the newly added batteries in the replacement power station in May is 61,309 * 32 = 1,103,562 yuan. According to the above formula, the depreciation life is 6, and the depreciation tax rate is 0.13. Then, it can be calculated that the depreciation cost of the newly added spare batteries in the replacement power station in May in the month of May is 1,103,562 / 6 / 12 / 1.13 = 13,564 yuan.

[0059] Finally, by summing up the depreciation cost of the newly added battery in the historical calculation period in the current calculation period and the depreciation cost of the newly added battery in the current calculation period in the current calculation period, the total depreciation cost of the current calculation period can be obtained.

[0060] For example, the depreciation cost of the newly added spare batteries in the replacement power station in March in May is 24,114 yuan, the depreciation cost of the newly added spare batteries in April in May is 10,550 yuan, and the depreciation cost of the newly added spare batteries in May in the month of May is 13,564 yuan. Then, the total depreciation cost in May is the sum of the depreciation costs of the above three months, that is, 24,114 + 10,550 + 13,564 = 48,228 yuan.

[0061] In a possible implementation manner of the present invention, the formula for calculating the depreciation cost is determined, and the parameters in the formula, namely the depreciation life and the depreciation tax rate, are also fixed. In this way, the depreciation cost of the newly added spare batteries in each calculation period is fixed. That is to say, the depreciation cost of the spare batteries in the present invention does not change due to the change in the usage time of the spare batteries and is fixed in each calculation period. For example, the depreciation cost of the spare batteries newly added by the battery swapping station in March is 24,114 yuan. That is to say, for the batch of spare batteries newly added by the battery swapping station in March, the depreciation cost in each subsequent month is 24,114 yuan. At the same time, the present invention calculates the depreciation cost at the beginning of the calculation period for the newly added spare batteries. In this way, it provides greater convenience for the calculation of the total depreciation cost of the current calculation period. It only needs to calculate the depreciation cost of the newly added batteries in the current calculation period in the current calculation period, and then sum it with the depreciation cost of the newly added batteries in the directly obtainable historical calculation period.

[0062] Furthermore, the spare batteries will be scrapped after reaching the service life. After the batteries are scrapped, the battery swapping station will continue to add new spare batteries to ensure an adequate supply of spare batteries. At this time, the number of newly added spare batteries is the same as the number of scrapped spare batteries. This can ensure that there will be no problem that the battery swapping station has too many spare batteries that cannot be accommodated in the battery compartments or too few spare batteries resulting in a reduction in the number of electric vehicles that can be supplied. At the same time, precisely because of the balance or equality between the number of scrapped spare batteries and the newly added number, the depreciation cost of the newly added spare batteries in each calculation period will be the same as the depreciation cost of the scrapped spare batteries (as long as the numbers of the two are ensured to be the same). For example, the depreciation life of the spare batteries is 6 years, that is, 72 months. Suppose the battery swapping station newly added a batch of spare batteries A in the 3rd month, and this batch of spare batteries A will be scrapped in the 75th month. Then the battery swapping station will surely add a new batch of spare batteries B in the 75th month to fill the vacancy of A. At this time, as long as the numbers of A and B are equal, the depreciation cost of A can be directly used as the depreciation cost of B to participate in the calculation of the cost of the spare batteries in the calculation period, without the need to recalculate the depreciation cost of the spare batteries B again. In this way, the cyclic use calculation of the depreciation cost of the battery swapping station can be realized, and the calculation efficiency of the cost of the spare batteries can be further improved.

[0063] Step 104: Determine the total battery cost of the current calculation period according to the newly added battery cost of the current calculation period and the total depreciation cost of the current calculation period.

[0064] After calculating the newly added battery cost and the total discount cost of the current calculation period, summing these two costs can obtain the total cost of the spare batteries in the current calculation period.

[0065] For example, the total depreciation cost of the battery swapping station in May is 48,228 yuan, and the cost of newly added batteries is 1,103,562 yuan. Then the total cost of spare batteries of the battery swapping station in May is 48,228 + 1,103,562 = 1,151,790 yuan.

[0066] In a possible implementation manner of the present invention, after calculating the total cost of spare batteries in a calculation period, the battery rent in a calculation period can be further calculated to further calculate the profit in a calculation period: Profit = Rent - Cost. By calculating the profit, the battery swapping station enterprise can understand the profit and loss situation of the battery swapping station and provide a reference basis for the operation of the battery swapping station.

[0067] As a possible implementation manner, the battery rent in the current calculation period can be calculated through the following formula: Battery rent = (Cost of newly added batteries in the historical calculation period + Cost of newly added batteries in the current calculation period) / 12 / Depreciation life of the battery, or, Battery rent = Total cumulative newly added battery quantity of the battery swapping station * Unit price of the battery / Depreciation life of the battery / 12. The total cumulative newly added battery quantity of the battery swapping station here includes the newly added battery quantity in the current calculation period and the newly added battery quantity in the historical calculation period.

[0068] For example, the total cost of spare batteries of the battery swapping station in May is 1,151,790 yuan, and the battery rent of the battery swapping station in May is (1,961,888 + 858,326 + 1,103,562) / 12 / 6 = 54,497 yuan. Then it can be calculated that the profit of the battery swapping station in May is -1,097,293 yuan. It should be noted that the cost brought by the newly added batteries accounts for a relatively large proportion in the total cost of spare batteries of the battery swapping station in May, which is also the main factor resulting in a negative profit in May. Since the depreciation life of the battery is 6 years, that is, 72 months, and the battery storage space of the battery swapping station is limited, new batteries will not be added every month during these 72 months. Generally, a battery swapping station only adds new batteries in the first 10 months of the battery depreciation life. This makes the profit of the battery swapping station mainly concentrated in the second half of the 72 months. Therefore, the profit will be negative in the first half of these 72 months.

[0069] Based on the same inventive concept, the present invention also provides a cost calculation device for spare batteries of a battery swapping station, and its structure is as Figure 2 shown.

[0070] Figure 1 is a schematic structural diagram of a cost calculation device for spare batteries of a battery swapping station provided by the present invention.
