Then, the control unit 731 determines the current eco-driving level based on the information regarding the overload while the electric vehicle 71 is being driven using the electric power from the replaceable battery 9 before replacement (S204). .

As an example, assume that the eco-driving level is set in two levels, Lv1 and Lv2. Further, it is assumed that the information regarding overload is the number of sudden starts and/or sudden decelerations. Note that a plurality of levels of three or more may be set as the level of eco-driving.

As an example, the control unit 731 determines that the level is LV2 if the number of sudden starts and/or sudden decelerations is less than 10 times, determines that the level is LV1 if it is less than 20 times, and determines that the level is LV1 if the number of sudden starts and/or sudden decelerations is less than 20 times. In other words, it is determined that the eco-driving benefit is not applicable. Note that the threshold value for the number of sudden starts and/or sudden decelerations is just an example, and can be set arbitrarily.

Hereinafter, the explanation will be continued assuming that the level of eco-driving determined in the process of S204 is LV1.

The control unit 731 determines the display mode of the fee area (S205). Specifically, the control unit 731 matches the battery type, remaining power, eco-driving level, and fee information 735a, and determines the applicable fee. Then, the control unit 731 determines the display mode of each fee according to the determination result.

Furthermore, the control unit 731 displays the price display screen 630 in the display mode of the determined price range (S206).

Note that the determination of the level of eco-driving and the calculation of fees based on the level of eco-driving may be performed when issuing a slip, similarly to the battery exchange system 1 according to each of the embodiments described above.

In the example of FIG. 12, a change in bold (highlighted display) is shown as a change in display mode.

In the example of FIG. 12, the charges for type A and type B battery types are displayed in bold in the standard price display area 613. Further, type C charges are displayed in a normal display mode. Accordingly, the price display screen 630 indicates that type A and type B battery types can be loaded into the electric vehicle 71 of the user 7 .

In the example of FIG. 12, in the remaining power benefit display area 615, charges for remaining power of 20% or more are displayed in a bold display format. As a result, the price display screen 630 indicates that when replacing the replaceable battery 9 at this time, a benefit when the remaining power is 20% or more, that is, a discount of 2.0 Indian rupees per kWh can be applied. It shows.

In the example of FIG. 12, in the eco-driving benefit display area 631, the fee for the LV1 eco-driving level is displayed in bold. As a result, the price display screen 630 indicates that when replacing the replaceable battery 9 at this time, a benefit when the eco-driving level is LV1, that is, a discount of 1.0 Indian rupees per kWh can be applied. It shows.

In this way, in the battery exchange system 1 according to the embodiment, the user terminal 73 is configured to display a price including discount information corresponding to the level of eco-driving, as well as the remaining power of the replaceable battery 9 before exchange. It is composed of

According to this configuration, since it is possible to display a price that provides an incentive for battery-friendly usage, it is possible to guide the driver to driving manners that reduce overload on the replaceable battery 9. Reducing the overload on the replaceable battery 9 suppresses battery deterioration and contributes to reducing the asset value of the replaceable battery 9.

Additionally, the user 7 can grasp applicable charges and discounts in real time even if the applicable charge information differs for each charging station or for each time period. That is, according to the battery exchange system 1 according to the embodiment, the motivation of the user 7 for eco-driving can be improved.
