  The alarm output unit 11 outputs a predetermined alarm sound from a speaker as an alarm device under the control of the control unit 15. This alarm sound includes a single beep sound, a sound combining a plurality of beep sounds, a sound, and the like.

  The harm detection unit 12 detects a stop of power supply via the cables 5 and 6 connected to the battery terminal 2. Specifically, the danger detection unit 12 is configured to detect the cables 5 and 6 from the battery terminal 2 by a third party. , And disconnection of the cables 5 and 6 are detected.

  Here, an example of the configuration for detecting the extraction of the third-party cables 5 and 6 will be described with reference to FIG. FIG. 3 is a diagram showing an example for detecting cable disconnection, FIG. 3 (a) is an example when the electrical connection of the cable to the battery terminal is not detected, and FIG. 3 (b) is the battery terminal. It is an example in the case of detecting the electrical connection of the cable with respect to.

  As shown in FIG. 3, each of the terminals 2a and 2b of the battery terminal 2 has a conductive plug that is movable in the axial direction of the terminals 2a and 2b and is biased toward the cables 5 and 6 side. 8 is attached. The plug 8 is attached via, for example, an elastic body 9 (spring member or the like).

  On the other hand, a conductive recess 1b into which the plug 8 is inserted is formed on the upper surface of the housing 1a. By inserting the plug 8 into the recess 1b, the outer peripheral surface of the plug 8 and the recess 1b The electrical connection of the cables 5 and 6 to the battery terminal 2 is detected by contact with the inner peripheral side surface. That is, before the cables 5 and 6 are attached to the battery terminal 2, the plug 8 is provided on the upper portion of the recess 1b, so that the electrical connection of the cables 5 and 6 to the battery terminal 2 is not detected. When attached to the battery terminal 2, the plug 8 is pressed downward by the cable terminals 5 a and 6 a of the cables 5 and 6, the plug 8 is received in the recess 1 b, and the cables 5 and 6 to the battery terminal 2 are accommodated. An electrical connection is detected.

  In the present embodiment, using such an operation, the controller 15 is first operated when the electrical connection of the cables 5 and 6 to the battery terminal 2 is first detected. The control unit 15 performs control to issue an alarm when the cables 5 and 6 are removed from the battery terminal 2 by a third party.

  In addition, as an example of detecting the disconnection of the cables 5 and 6, a measurement device that measures the current between the battery terminals 2 or measures the current value in the cables 5 and 6 is provided. The presence or absence of cutting 6 may be determined.

  The communication unit 13 communicates with a predetermined mobile phone of the vehicle owner, for example. The communication is, for example, an operation of notifying a predetermined document (alarm information indicating that the vehicle is in danger) by e-mail or the like. In addition, a predetermined sound may be output to the mobile phone.

  Although not shown, the control unit 15 includes a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), and the like, and the CPU executes various programs stored in the ROM, for example. The entire battery device 1 is controlled and functions as an example of the control means of the present application. Specifically, the control unit 15 operates the alarm device based on the detection result by the hazard detection unit 12 to issue a predetermined alarm. More specifically, an alarm sound is output, or alarm information is notified to an external communication terminal (for example, the owner's mobile phone).

  Hereinafter, an operation when a third party pulls out or cuts a cable will be described with reference to FIG. FIG. 4 is a flowchart showing an example of the control operation of the battery device.

  First, the control unit 15 determines whether or not the cables 5 and 6 are respectively attached to the battery terminal 2. If this determination is affirmed, the process proceeds to step S102, and if not, the control unit 15 waits.

  Next, in step S102, the control unit 15 operates the function of the security unit 10. Thus, in this embodiment, the cables 5 and 6 are electrically connected to the battery terminal 2 so that the security function is activated. In essence, the control unit 15 causes the hazard detection unit 12 to start monitoring a cable extraction operation or a cutting operation by a third party.

  Next, in step S103, the control unit 15 determines whether or not a harmful operation to the vehicle such as a pulling operation or a cutting operation of the cables 5 and 6 by a third party has been detected. If this determination is affirmed, the process proceeds to step S104. If the determination is negative, the process waits until a harmful action to the vehicle is detected.

  Next, in step S104, the control unit 15 outputs a predetermined alarm sound to the alarm device or notifies (transmits) alarm information to a predetermined external communication terminal, and ends the process. By this operation, a third party can be intimidated, or the owner of the vehicle can be notified that there is a risk of harm to the vehicle.

  Note that it is not meaningful to continue sounding the alarm sound for a long time. For example, it is preferable to stop the security function after the alarm sound is output for a certain period of time and then stop the security function. In such a case, when the security function is started again, the action in step S102, that is, the cables 5 and 6 may be newly inserted into the battery terminal 2.

  As described above, according to the battery device 1 of the present embodiment, the security function is mounted on the battery body, and the cables 5 and 6 are removed from the battery terminal 2 by a third party, or the cables 5 and 6 are removed. When the cable is disconnected, a predetermined alarm sound and notification of alarm information to the owner are performed using the battery body as a power source, so that the security function is not canceled by disconnecting or disconnecting the cables 5 and 6. The security unit 10 operates. Further, complicated wiring or the like is not required in the manufacturing process of the battery device 1. Therefore, it is possible to manufacture the battery device 1 easily and without cost, and it is possible to reliably issue an alarm to a third party when the vehicle is harmed.

  In addition, since the security unit 15 is built in the battery housing 1a, it is possible to ensure the power supply even if the cables 5 and 6 are disconnected, and reliably when the vehicle is harmed. An alarm can be issued.

  Further, the battery device 1 of the present embodiment includes a plug 8 that is movable in the axial direction of the battery terminal 2 and is always biased toward the cables 5 and 6, and the terminal is moved by the movement of the plug 8. By detecting the presence / absence of electrical connection between the cables 5 and 6 with respect to 2, the presence / absence of the extraction of the cables 5 and 6 by a third party is detected. In this way, it is possible to detect the presence or absence of the cables 5 and 6 easily and reliably with a simple configuration.

  The present application is not limited to the above embodiment, and various modifications can be made. For example, in the above-described embodiment, the security unit 10 is built in the housing 1a in which the battery main body is accommodated. However, the security unit 10 is manufactured as a separate body, and the security unit 10 is formed on the upper surface of a commonly used battery. A separate body provided with the security unit 10 may be attached via a predetermined fixing means. In general, the fixing means may be any means as long as it can fix predetermined members to each other, and it is fixed with screws or provided with a convex portion and a concave portion in each member to be fixed. But it doesn't matter.

  In this embodiment, for convenience, the present invention is applied to a battery used in an automobile. However, the present invention can be applied not only to a motorcycle but also to a moving body such as a ship or an airplane.

  Further, the hazard detection unit 12 may be configured to detect only the current value in the cables 5 and 6 without using the plug 8. This is because by detecting only the current value in the cables 5 and 6, it is possible to detect not only the disconnection of the cables 5 and 6, but also the disconnection of the cables 5 and 6. In such a case, the security function automatically operates by supplying electricity to the security unit 10.
