Second Embodiment Next, a second embodiment will be described with reference to FIGS. In these drawings, elements that are the same as or correspond to those in the first embodiment are assigned the same reference numerals and explanations thereof are omitted.

Although the first embodiment is an example embodied in an electric vehicle equipped with a navigator, a bulky and expensive object such as a navigator cannot be attached to a simple electric vehicle such as an electric bicycle. Embodiment 2 assumes such an electric vehicle, and the electric vehicle is provided with only a simple device.

FIG. 6 shows a schematic configuration of the second embodiment. In this case, the electric traveling vehicle 1 is as simple as an electric bicycle, and therefore, the mobile phone 17 as a communication terminal,
Only the remaining capacity measuring unit 12 and the alarm unit 13 are provided. The battery management device 3 is exactly the same as that of the first embodiment.

On the other hand, the customer guidance device 2 is provided with a control unit 21 including a CPU, a storage unit 22, a telephone 23, a communication unit 24 as a communication terminal, an input unit 25, and an output unit 26. Although it is the same as the first embodiment, it is different from the first embodiment in that a traveling position detection unit 27 is further provided. This is the same as in the electric traveling vehicle 1 according to the first embodiment.
Since the vehicle 4 is not provided, it is possible to cope with the fact that the electric traveling vehicle 1 side cannot notify the customer guidance device 2 of an accurate traveling position. That is, when the traveling position detection unit 27 in the second embodiment receives a report from the electric traveling vehicle 1 that the remaining electric capacity has decreased to a predetermined value, the relay antenna that directly receives the radio wave from the mobile phone 17 is provided. The position of No. 5 is detected and this is regarded as the position of the electric vehicle 1.

The position of the relay antenna 5 is detected by using, for example, a sub-address notification function used for data communication between the mobile phone 17 and the relay station. More specifically,
If each relay antenna 5 puts its own sub-address on the signal, the position of this relay antenna 5 can be detected.

Therefore, in the second embodiment, the position of the relay antenna 5 detected by the traveling position detector 27 is regarded as the traveling position, the available battery stands around this position are searched, and this battery stand is related. Information is transmitted to the electric vehicle 1.

The main points that are different from the first embodiment are described above, and this point will be described more specifically based on the flowchart of FIG. 7. Note that FIG. 7 shows a processing procedure when the electric vehicle 1 inquires of the customer guide device 2 about information about the battery stand.

While the electric traveling vehicle 1 is traveling, the remaining electric capacity of the traveling battery is constantly measured by the remaining electric capacity measuring unit 12 (step S21). When the remaining electric capacity reaches a predetermined value, the control unit 11 receives the signal indicating that the remaining electric capacity is low, activates the alarm unit 13, and issues an alarm (step S2).
2). At this time, the control unit 11 sends a connection request to the mobile phone 17 as a communication terminal, and notifies the customer guide device 2 via the Internet 4 that the remaining electric capacity has decreased to a predetermined value (step S23). Customer guidance device 2
Is received by the communication unit 24 (step S24).
Further, in the customer guidance device 2, the control unit 21 detects the identification number of the communication terminal 17 of the electric vehicle 1 (the telephone number or the mail address of the mobile phone 17) and identifies the electric vehicle 1 corresponding to this number. The control is performed such that the number is searched, and further, the identification number and the type of the traveling battery corresponding to this identification number are searched (step S25). Furthermore, the control unit 2
1 controls the traveling position detection unit 27 to detect the position of the relay antenna 5 used for communication of the mobile phone 17 (step S26). The detected position of the relay antenna 5 is regarded as the traveling position.

Then, the control unit 21 allows the battery including the location, store name, telephone number, homepage address, and distance from the current location of the battery stand that is exchanging the traveling battery of this type from the type of the traveling battery. Controlled to retrieve information about the stand. Further, the control unit 21 is controlled to retrieve information about the battery history including the type of the running battery, the number of years of use, and the number of times of charging from the identification number of the running battery (step S27). Then, both of these pieces of information are transmitted to the electric traveling vehicle 1. The electric vehicle 1 receives this and displays it on the screen of the mobile phone 17 (step S28).

FIG. 8 shows an example of the screen structure displayed on the screen of the mobile phone 17 at this time. In this example, information about several battery stands is displayed by selecting "return" or "next". The displayed contents are "current location" (the location where the electric traveler 1 travels), "location" (the location of the battery stand),
"Store name", "phone number" and "distance" (current distance)
And so on. After confirming the information of this character display, by selecting "reservation", the battery replacement reservation can be made to the battery management device 3 of the battery stand.

The processing procedure for the battery replacement reservation is the same as the processing procedure in the first embodiment, that is, the one shown in FIG. After the battery stand for battery replacement is determined, in the second embodiment, since the navigator 14 as in the first embodiment is not provided, the map is further viewed according to the information taught by the customer guide device 2. However, the electric vehicle 1 will be driven to the reserved battery stand. Also, the processing procedure after reaching the battery stand is similar to that in the first embodiment.

According to the second embodiment, the electric vehicle 1
When the remaining electric capacity of the running battery has dropped to a predetermined value, according to the information obtained from the customer guide device 2, the battery management device 3 of the battery stand, which is engaged in the running battery replacement work, is contacted to replace the battery. You can make a reservation and go to the battery stand to instantly replace it with a charged running battery.
Therefore, when it is necessary to charge the vehicle while driving due to the consumption of the traveling energy, it is not necessary to wait until the charging is completed unlike the conventional case, and the traveling energy can be replenished in a short time, and the range of action can be expanded. You can In addition, since the amount is converted on the spot at the time of this exchange, no complicated procedure is left behind, and the procedure is simple. Further, in this exchange system, the traveling battery is charged at the battery stand and reused as an exchange battery, so that no waste of resources occurs. In addition, it has an alarm unit that issues an alarm when the remaining capacity measuring unit detects that the remaining capacity of the running battery has dropped to a predetermined value, so it can alert the driver and miss it. It is possible to reliably prevent the accident. The above points are the same as in the case of the first embodiment.

The effects different from those of the first embodiment are as follows. That is, in the second embodiment, the mobile phone 1
Since the position of the electric vehicle 1 can be estimated by using the position of the relay antenna 5 that first receives the radio wave of No. 7,
Information about the battery stand can be obtained from the customer guide device 2 without providing a bulky and expensive navigator for the electric vehicle 1, and the electric vehicle 1 can be easily equipped.

Next, the above-mentioned first and second embodiments
A modified example will be described. (1) The above-described first and second embodiments can be modified as follows. The battery inventory management information of the battery management device is periodically stored in the customer guide device 2 from each battery stand. And electric vehicle 1
When transmitting the information about the battery stand to, the replaceable battery stand of the traveling battery is selected based on the battery inventory management information stored periodically or irregularly (as appropriate). By doing so, it is possible to increase the certainty of the establishment of the reservation when the battery replacement reservation is made.

(2) Further, in the first embodiment, the position detecting unit 27 employed in the second embodiment is attached to the customer guide device 2 so that the first and second embodiments can be used in common. May be. In this case, the information about the battery stand and the information about the battery history as described in the first embodiment are transmitted to the electric vehicle of the first embodiment, but the position detecting unit 27 detects the relay antenna 5 of the relay antenna 5. There is no need to detect the location or send it.
