[0024] Hereinafter, embodiments of the simulation device of the present invention will be described with reference to the drawings.

[0025] Figure 1 FIG. 1 is a diagram showing an example of the structure of the simulation system 1 according to the present embodiment. Figure 1 As shown, the simulation system 1 includes a simulation device 100 and an information processing device 200 .

[0026] The simulation device 100 simulates the vehicle performance of the vehicle and the battery characteristics of the battery. The simulation device 100 is communicatively connected to the information processing device 200 via the network NW. The simulation device 100 accesses the information processing device 200 and acquires information from the market battery database 210 and the vehicle database 220 of the information processing device 200.

[0027] The information processing device 200 is communicatively connected to the simulation device 100 via the network NW. The information processing device 200 includes a market battery database 210 storing performance information and characteristic information of batteries distributed in the market, and a vehicle database 220 storing performance information and characteristic information of vehicles.

[0028] In addition, the market battery database 210 can also store various information such as battery capacity, battery weight, battery voltage / current characteristics, battery internal impedance characteristics, management temperature range, guaranteed working temperature range, battery type, battery material, battery size, capacity maintenance rate, output maintenance rate, sales price, remaining life (estimated value), manufacturer, model, manufacturing date, etc.

[0029] Figure 2 FIG. 1 is a diagram showing an example of the structure of the simulation device 100. Figure 2 As shown, the simulation device 100 includes a control unit 11 , a storage unit 12 , a communication unit 13 , a display unit 14 , and an operation unit 15 .

[0030] The control unit 11 is implemented by executing a program (software) by a hardware processor such as a central processing unit (CPU). Some or all of these components may be implemented by hardware (including circuitry) such as a large-scale integrated circuit (LSI), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), and a graphics processing unit (GPU), or by the collaboration of software and hardware. The program may be pre-stored in a storage device (storage device with a non-volatile storage medium) such as a hard disk drive (HDD) and a flash memory, or may be stored in a removable storage medium (non-volatile storage medium) such as a DVD and a CD-ROM, and the storage medium may be set in a drive device for installation.

[0031] The storage unit 12 is implemented by a storage device having a non-transitory storage medium, such as a hard disk drive (HDD), a flash memory, an electrically erasable programmable read only memory (EEPROM), a read only memory (ROM), or a random access memory (RAM).

[0032] The communication unit 13 is a communication interface for communicating with an external device such as a server via the network NW.

[0033] The display unit 14 is a device that displays images and is, for example, a liquid crystal display (LCD) or an organic electroluminescence (EL).

[0034] The operation unit 15 is composed of buttons for operating the display unit 14. In addition, the display unit 14 and the operation unit 15 may be a touch panel in which these functions are integrated. In this case, the operation unit 15 may be a switch of a graphical user interface (GUI) displayed on the display unit 14. In addition, the operation unit 15 may also be a mechanical button.

[0035] Next, the processing of the control unit 11 will be described. Figure 2 As shown, the control unit 11 includes a battery performance acquisition unit 111 , a vehicle information acquisition unit 112 , a simulation unit 113 , and a result display unit 114 .

[0036] The battery performance acquisition unit 111 acquires performance information of batteries that can be mounted on the vehicle. Specifically, the battery performance acquisition unit 111 acquires performance information of multiple batteries with different performances from the market battery database 210. In addition, the battery performance information includes battery output characteristics, battery capacity characteristics, and battery weight.

[0037] In addition, the market battery database 210 may be stored in the storage unit 12 instead of the information processing device 200. In this case, the storage battery performance acquisition unit 111 may also acquire the performance information of the storage battery from the market battery database stored in the storage unit 12.

[0038] The vehicle information acquisition unit 112 acquires vehicle information of the vehicle. Specifically, the vehicle information acquisition unit 112 acquires vehicle information including weight information of the vehicle from the vehicle database 220 .

[0039] In addition, the vehicle database 220 may be stored in the storage unit 12 instead of the information processing device 200. In this case, the vehicle information acquisition unit 112 may also acquire the vehicle information from the vehicle database stored in the storage unit 12.

[0040] The simulation unit 113 simulates the vehicle performance of the vehicle and the battery characteristics of the battery based on the battery performance information and the vehicle information. Here, the vehicle performance of the vehicle includes braking performance, acceleration performance, and driving range. In addition, the battery characteristics include output characteristics and capacity characteristics.

[0041] As described below, braking performance is affected by the weight of the vehicle, the weight of the battery, and the output characteristics of the battery. In addition, acceleration performance is affected by the weight of the vehicle, the weight of the battery, and the output characteristics of the battery. In addition, driving range is affected by the weight of the vehicle and the capacity characteristics of the battery.

[0042] Furthermore, the simulation unit 113 may simulate the vehicle performance of the vehicle and the battery characteristics of the battery, as well as the average fuel consumption of the vehicle, the degradation of the battery, and the remaining life of the battery.

[0043] The result display unit 114 displays the simulation result performed by the simulation unit 113 on the display unit 14. Thus, the information processing device 200 can notify the user of the simulated vehicle performance and battery characteristics of the battery.

[0044] Figure 3 is a diagram showing an example of the flow of vehicles and batteries. Figure 3 As shown, user P who purchased vehicle A with battery B sells vehicle A and switches to vehicle C without a battery. At this time, user P purchases a combination of the temporarily sold battery B and a new battery D for use.

[0045] In addition, user Q who purchased used vehicle A can purchase a combination of sold battery B and new battery D and use it in vehicle A without a battery. In this way, the simulation device 100 of this embodiment can provide users who purchase vehicles and batteries separately with simulations of vehicle performance and battery characteristics of batteries when different types of batteries are combined.

[0046] Figure 4 is a graph showing the correlation between the weight of a vehicle and its effect on vehicle performance. Figure 4 As shown, the performance information of the battery includes the battery output characteristics, battery capacity characteristics and battery weight. The information of the vehicle body includes the weight of the vehicle. In addition, the vehicle performance includes braking performance, acceleration performance and driving range.

[0047] Batteries have two characteristics: output characteristics and capacity characteristics. The battery output characteristics affect the vehicle's braking and acceleration. The battery capacity characteristics affect the vehicle's driving range.

[0048] In addition, the weight of the battery will affect the braking, acceleration and driving range of the vehicle. The weight of the vehicle will affect the braking, acceleration and driving range of the vehicle. As such, it can be seen that when batteries with different performances are combined, the vehicle performance will be affected.

[0049] Figure 5 is a graph showing the battery output characteristics and battery capacity characteristics. As mentioned above, the battery output characteristics will affect the braking and acceleration of the vehicle. Figure 5 As shown in the battery output characteristics, there are high-power type batteries whose output power is large both during charging and discharging, and low-power type batteries whose output power is smaller than that of the high-power type batteries both during charging and discharging.

[0050] In addition, as mentioned above, the battery capacity characteristics will affect the driving range of the vehicle. Figure 5 As shown in the battery capacity characteristics of , there are low-capacity type batteries with low battery capacity and high-capacity type batteries with high battery capacity.

[0051] Figure 6 It is a drawing that will Figure 5 The figure shows the simulation results when the batteries are combined. When two low-capacity and high-output batteries (weight X) are combined in parallel, and when two high-capacity and low-output batteries (weight Y) are combined in parallel, the weight of the batteries is doubled (2×X, 2×Y), respectively, and the battery characteristics do not change.

[0052] On the other hand, when two low-capacity and high-output batteries (weight X) and high-capacity and low-output batteries (weight Y) are combined in parallel, the characteristics of the batteries are such that the discharge capacity becomes an intermediate value between the low-capacity and high-capacity batteries, and the single-cell voltage characteristics also become an intermediate value between the high-output and low-output batteries. In addition, the weight of the battery is X+Y, and the vehicle performance of the vehicle changes as the weight of the entire vehicle changes. In this way, the simulation unit 113 can simulate the battery characteristics of the battery.

[0053] Figure 7 is a diagram showing another example of simulation results. Figure 7 As shown, the simulation results of braking, acceleration and driving range implemented by the simulation unit 113 are shown by summary stage evaluation, and the simulation results of battery characteristics are shown by type and category representing the characteristics of the battery. Thus, the user can know the vehicle performance of the simulated vehicle and the battery characteristics of the battery.

[0054] Figure 8 1 is a flowchart showing the flow of processing of the simulation device 100 .

[0055] In step S1 , the battery performance acquisition unit 111 acquires performance information of a battery that can be mounted on a vehicle.

[0056] In step S2 , the vehicle information acquisition unit 112 acquires vehicle information of the vehicle.

[0057] In step S3 , the simulation unit 113 simulates the vehicle performance of the vehicle and the battery characteristics of the battery based on the performance information of the battery and the vehicle information.

[0058] In step S4 , the result display unit 114 displays the result of the simulation performed by the simulation unit 113 on the display unit 14 .

[0059] According to this embodiment, for example, the following effects can be achieved.

[0060] The simulation device 100 includes a battery performance acquisition unit 111 that acquires performance information of a battery that can be mounted on a vehicle; a vehicle information acquisition unit 112 that acquires vehicle information of the vehicle; and a simulation unit 113 that simulates vehicle performance of the vehicle and battery characteristics of the battery based on the battery performance information and vehicle information. Thus, the simulation device 100 can simulate vehicle performance of the vehicle and battery characteristics of the battery corresponding to the mounted battery, so that the user can know what performance and characteristics the vehicle has according to the mounted battery.

[0061] In addition, the storage battery performance acquisition unit 111 acquires performance information of a plurality of storage batteries having different performances. Thus, the simulation device 100 can perform simulation based on performance information of various storage batteries distributed on the market.

[0062] In addition, the vehicle information includes the weight information of the vehicle. In addition, the performance information of the battery includes the battery output characteristics, the battery capacity characteristics, and the battery weight. In addition, the vehicle performance of the vehicle includes the braking performance, the acceleration performance, and the driving range. Thus, the simulation device 100 can consider the information that affects the vehicle performance of the vehicle and the battery characteristics of the battery and perform the simulation.
