Description

[Technical Field]

[0001] The present disclosure relates to a system for setting rental fees for electric vehicles. [Background technology]

[0002] There is a rental system that rents electric vehicles and power storage devices installed in electric vehicles to users and collects rental fees. For example, Patent Document 1 discloses an electric vehicle rental fee setting system that sets a rebate rate according to the degree of deterioration of the power storage device. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2019-095990 Summary of the Invention [Problem to be solved by the invention]

[0004] In the rental fee setting system disclosed in Patent Document 1, behaviors that contribute to the degree of deterioration of an electric vehicle's power storage device include a low SOC (State Of Charge) of the power storage device and the number of times it has been quick-charged. For example, if the vehicle is returned with a high SOC, the charging time required is shorter, making it easier to accept it for rental again, and so the rental fee is set to be lower. Furthermore, if the number of quick charges increases, the power storage device will deteriorate more quickly, so the rental fee is set to be higher.

[0005] On the other hand, degradation of an energy storage device can occur as both a temporary increase in resistance (high-rate degradation) and an irreversible increase in resistance. Temporary high-rate degradation can be resolved by leaving the device unused for a period of time after rapid charging and charging / discharging. Therefore, if there is no next user for a while after returning the device, the performance of the energy storage device will recover during the unused period.

[0006] As such, degradation due to rapid charging includes transient degradation, and so there is a possibility that it will improve over time, leaving room for improvement in setting the rebate rate.

[0007] The present disclosure has been made to solve such problems, and aims to provide a rental fee setting system that sets appropriate rental fees. [Means for solving the problem]

[0008] The rental fee setting system according to the present disclosure is a rental fee setting system for an electric vehicle equipped with a secondary battery, which includes a high-rate degradation acquisition means for acquiring the high-rate degradation state of the secondary battery when a user starts using the vehicle, and which sets a rebate rate for the current user when the next user starts using the vehicle based on the high-rate degradation state of the current user and the high-rate degradation state of the next user acquired by the high-rate degradation acquisition means. This makes it possible to provide a rental fee setting system that sets appropriate rental fees. [Effects of the Invention]

[0009] The present disclosure makes it possible to provide a rental fee setting system that sets appropriate rental fees. [Brief explanation of the drawings]

[0010] [Figure 1] 1 is a flowchart of a rental fee setting system according to the present disclosure. DETAILED DESCRIPTION OF THE INVENTION

[0011] Hereinafter, an embodiment of the present disclosure will be described with reference to the drawings. Fig. 1 is a flowchart showing a rental fee setting process for an electric vehicle equipped with a secondary battery according to the present disclosure. Each step shown in Fig. 1 is executed by a management server, software processing by the management server, hardware (electrical circuits) created within the management server, etc.

[0012] First, it is determined whether the rented electric vehicle has been returned (S100). If it is determined that the rented electric vehicle has been returned, the return date and time of the electric vehicle, information about the return station, and the vehicle usage history are acquired (S102). Furthermore, in this step, the high-rate deterioration state (first high-rate deterioration state) of the returned vehicle is acquired. Therefore, the rental fee setting system according to the present disclosure has high-rate deterioration acquisition means for acquiring the high-rate deterioration state of the vehicle.

[0013] Next, a rebate rate A(1) is set based on the SOC of the power storage device of the electric vehicle at the time of rental (S104). For example, the rebate rate A(1) is set to a larger value when the SOC at the time of rental is small than when the SOC at the time of rental is large.

[0014] Next, a rebate rate A(2) based on the SOC of the power storage device of the electric vehicle at the time of return is set (S106). For example, when the SOC of the power storage device at the time of return is high, the rebate rate A(2) is set to a larger value than when the SOC at the time of return is low.

[0015] Next, a rebate rate A(3) is set based on the number of behaviors that contribute to deterioration of the power storage device during use from the time the device is rented until the time it is returned (S108). For example, the rebate rate A(3) is set to a larger value when the number of behaviors that contribute to deterioration of the power storage device is small than when the number of behaviors that contribute to deterioration of the power storage device is large.

[0016] Next, a return rate A(4) is set based on the time the power storage device in use has been left in a state that contributes to deterioration (S110). The return rate A(4) is set to a larger value when the time the power storage device has been left in a state that contributes to deterioration is short than when the time is long.

[0017] Next, a correction coefficient is set according to whether the behavior contributing to the deterioration of the power storage device is attributable to the user's usage pattern (S112). For example, if the number of times charging using a charging stand exceeds a threshold, it is determined that the behavior contributing to the deterioration of the power storage device is attributable to the user's usage pattern. On the other hand, if the number of times charging without using a charging stand exceeds a threshold, such as when the amount of regenerative braking is high, it is determined that the behavior contributing to the deterioration of the power storage device is not attributable to the user's usage pattern, i.e., is attributable to the performance of the power storage device.

[0018] Next, a rebate rate A(5) is set according to the location where the vehicle is returned (S114). For example, the rebate rate A(5) is set so that the rental fee is lower when the vehicle is returned to a station within a predetermined range than when the vehicle is returned to a station outside the predetermined range.

[0019] Next, the rebate rate A(6) is set according to the vehicle return time (S116). For example, the rebate rate A(6) is set so that if the vehicle is returned within a predetermined time period, the rental fee is lower than if the vehicle is returned outside the predetermined time period.

[0020] From this point, the process enters into the process of considering the correction term for when the next user will use the system. First, it is confirmed whether the next user will start using the system (S118). It is then confirmed whether a predetermined time, for example, a predetermined number of days such as xx days, has passed without the next user being scheduled (S120). If the predetermined time has passed, the transient resistance increase (high-rate degradation) has disappeared and the performance of the storage device has recovered, so this is taken into account in the correction term for the return rate A (7) described later.

[0021] When the next user, that is, the current user, starts using the vehicle, the high-rate deterioration state (second high-rate deterioration state) of the vehicle to be rented is acquired (S122).

[0022] Next, the first high-rate deterioration state and the second high-rate deterioration state are compared to set a return rate A(7) (S124). The return rate A(7) is set so that, for example, when the difference between the first high-rate deterioration state and the second high-rate deterioration state is small, the rental fee is lower than when the difference is large.

[0023] Next, the payout rate is determined (S126). Specifically, the payout rate is determined by adding the sum of the payout rates A(1), A(2), A(4), A(5), and A(6) to the value obtained by multiplying the payout rate A(3) by a correction coefficient and the payout rate A(7).

[0024] Next, the rebate amount corresponding to the determined rebate rate is calculated (S128). For example, the rental fee is set by multiplying the rental fee per unit time by the usage time, and the rebate amount is calculated by multiplying the set rental fee by the rebate rate. Points equivalent to the calculated rebate amount are rebated to the user, and the rebated points are reflected in the point information in the user information registered in advance.

[0025] A billing process may be executed to bill the user for the rental fee, or if the user has selected automatic payment using information such as a credit card registered in advance, a settlement process may be executed to settle the rental fee.The rental fee and the rebate rate may also be notified to the user's mobile terminal.At this time, for example, the rebate rates A(1) to A(7) and details of the correction coefficient may be notified to the user's mobile terminal.

[0026] In this way, a rental fee setting system that sets appropriate rental fees can be provided.

[0027] The present disclosure is not limited to the above-described embodiment, and can be modified as appropriate within the scope of the present disclosure.
