Japanese Patent Laid-Open No. 10-127981 JP 10-178293 A

Conventionally, electromagnetic fields generated from electrical products and power facilities are only emitted to the surroundings and have not been used. That is, there is a problem that the generated energy is not efficiently used. Therefore, the problem to be solved by the present invention is to provide a business method and a management method for a contactless charging device for efficiently using generated energy by using an electromagnetic field generated from an electric product or power facility. is there.

The above-mentioned problem is solved by providing a business method and a management method in which a contactless charging device is charged in an electromagnetic field generated from an electrical product or power facility, and the charged contactless charging device is sold. Is done. The contactless charging device means a device that can store wirelessly supplied power in a battery unit.

When installing a non-contact charging device, an application for permission to install the non-contact charging device is made to the manager or owner (hereinafter referred to as a contractor) of the installation location or installation object. Determine the installation location in consideration of the ease of installation of the contactless charging device and the strength of the electromagnetic field. An installation stand or an installation case may be provided at the installation location as necessary. Install a contactless charging device and collect the contactless charging device that has been charged. After the collection, the contactless charging device is processed into a power storage device according to customer needs, and the power storage device is sold. A reward may be paid to the contractor.

You may charge a non-contact charging device using electromagnetic waves instead of an electromagnetic field. At that time, it is necessary to replace the antenna of the contactless charging apparatus according to the frequency of the electromagnetic wave.

The contractor may install a contactless charging device. Since the non-contact charging device is non-contact, there is no particular need for electrical wiring connection or other work requiring specialized knowledge. Therefore, the installation work of the non-contact charging device by the contractor is easy. Therefore, it is possible to send the contactless charging device to the contractor, and the contractor installs, collects, and returns the contactless charging device to the operator. At that time, the reward for the contractor may be increased. However, when a contractor installs a contactless charging device for the first time, the operator needs to measure the electromagnetic field, the intensity and frequency of electromagnetic waves in advance, and pass a contactless charging device suitable for the measurement to the contractor.

A plurality of contactless charging devices may be installed for one contractor. The contractor may sell the contactless charging device that has been charged. At that time, a part of the profit obtained by the sale may be transferred to the contractor.

The contractor may use the charging energy obtained by the contactless charging device. At that time, the contactless charging apparatus may be a rental system, and a rental fee may be collected from the contractor periodically. The reward paid to the contractor may be adjusted depending on the amount of charging energy obtained by the contactless charging apparatus, the installation location of the contactless charging apparatus, the contractor's public and private sectors, and the like.

The contactless charging device used by the customer may be collected as needed and reused in this project.

By using an electromagnetic field that has not been used so far, it is possible to generate new benefits that did not exist before. Further, by making the charging medium a non-contact charging device that is non-contacting, the labor burden at the time of installation work is less than that of other charging media. In addition, no special knowledge is required for the installer.

The manager or owner of the installation location of the contactless charging apparatus can obtain a profit from the operator without any particular burden. And the customer base can be targeted at traders or general households who use electricity, and because it is very wide, it can be expected to generate great profits.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the present invention can be implemented in many different modes, and those skilled in the art can easily understand that the modes and details can be variously changed without departing from the spirit and scope of the present invention. Is done. Therefore, the present invention is not construed as being limited to the description of this embodiment mode.

(Embodiment 1)
The present invention will be described based on the flow of the contactless charging device. First, as shown in FIG. 1, the contactless charging apparatus is handed over from the operator to the contractor (first process 101). During this time, the operator may carry the contactless charging device directly or send it. Then, installation work of a non-contact charging device is performed. The installation work is performed by the operator or contractor when the operator carries the contactless charging device directly, or by the contractor when it is sent.

Next, the contactless charging apparatus that has finished charging is delivered from the contractor to the operator (second process 102). During this process, the contractor may send the contactless charging device or the operator may collect it directly from the installation location.

Next, the power storage device obtained by processing the contactless charging device so that wireless charging becomes impossible is delivered from the operator to the customer (third process 103). That is, the operator sells the power storage device to the customer.

Next, the power storage device used by the customer is delivered from the customer to the operator (fourth process 104). The process during this time may be collected directly from the customer by the operator or sent by the customer to the operator. If the customer is a mass retailer or the like, a collection box or the like may be provided in the same mass retailer to improve the efficiency of the collection work. However, this process is not necessary. That is, the power storage device may be sold to customers as disposable.

Next, the structure of the contactless charging apparatus will be described with reference to FIG. A contactless charging device 401 illustrated in FIG. 4 includes an antenna circuit 402, a charging circuit unit 403, and a battery unit 404. The charging circuit unit 403 includes a rectifier circuit 405, a power supply circuit 406, and a charging control circuit 407.

Further, the contactless charging device 401 may be covered with a protective material 408 in order to protect the charging circuit unit 403 and the battery unit 404 in an electromagnetic field. Since the protective material 408 is intended to protect the charging circuit portion 403 and the battery portion 404, a material such as a radio wave absorber that hardly transmits radio waves is used. For example, a material obtained by mixing a magnetic loss material into a base material can be used as a radio wave absorber. In this case, synthetic rubber and urethane may be used as the base material, and carbon material, ferrite, and carbonyl iron material may be used as the magnetic loss material.

The antenna circuit 402 has an antenna and a resonant capacitor connected in parallel to the antenna. The antenna may be any antenna that can receive radio waves and convert them into electrical signals. For example, a dipole antenna, a patch antenna, a loop antenna, a Yagi antenna, or the like can be used as the antenna. Further, depending on the type of antenna, it is not always necessary to provide the resonance capacitor in the antenna circuit 402. Further, the method of transmitting and receiving signals wirelessly in the antenna circuit 402 may be any of an electromagnetic coupling method, an electromagnetic induction method, and a radio wave method.

In addition, the battery unit means a battery that can recover the continuous use time by charging. For example, the size can be reduced by using a lithium battery such as a lithium polymer battery or a lithium ion battery using a gel electrolyte. Of course, as long as it is a rechargeable battery, the battery is not limited to these, and may be a chargeable / dischargeable battery such as a nickel metal hydride battery or a nickel-cadmium battery, or a large capacity capacitor such as an electric double layer capacitor. Etc. may be used.

Next, the operation principle of the contactless charging device will be described. A signal received by the antenna circuit 402 is input to the rectifier circuit 405 and converted into direct current. The power supply circuit 406 generates a current based on the power of the rectifier circuit 405 and charges the battery unit 404. The power supply circuit 406 keeps the output voltage of the rectifier circuit 405 constant and prevents the battery unit 404 from being overvoltaged. The charging control circuit 407 monitors the battery unit 404 so as not to be overcharged, and controls the power supply circuit 406 to suppress the charging amount when the charging amount increases.

Next, a method for processing the contactless charging apparatus will be described. As a processing example, there is a method of physically separating the battery unit 404 from the contactless charging device 401 as shown in FIG. The power storage device 412 sold at this time is the battery unit 404. When such processing is performed, the power storage device 412 after use cannot be recharged, so that it is possible to prevent the customer from reusing the non-contact charging device 401 without permission and obtaining an unfair advantage.

As another processing example, as shown in FIG. 6, there is a method of attaching a charging terminal 409 to the separated battery unit 404. The power storage device 412 sold at this time is a battery portion 404 and a charging terminal 409. When such processing is performed, for example, a battery of a car or a motorcycle can be charged. When the charging terminal 409 that matches the external terminal of the mobile phone is attached, the mobile phone can be charged.

As another processing example, as shown in FIG. 7, there is a method of transferring charging energy to a separately prepared secondary battery 410. The power storage device 412 sold at this time is the secondary battery 410.

Explain the rewards paid to contractors. The amount of the reward is determined by the operator according to the amount of energy charged, the installation location, the contractor's public and private sectors, and the private corporation. Moreover, when a contractor installs a non-contact charging apparatus or when a non-contact charging apparatus is sent to this business operator, an amount corresponding to that may be added.

By using the configuration of the present embodiment, it is possible to use an electromagnetic field that has not been used so far, and it is possible to generate a new benefit that has not existed before. Further, by making the charging medium a non-contact charging device that is non-contacting, the labor burden during installation work performed by the operator or contractor is less than that of other charging media. The installation work does not require special knowledge. And the contractor can make a profit from this business operator without any particular burden. And the customer base can be targeted at traders or general households who use electricity, and because it is very wide, it can be expected to generate great profits.

(Embodiment 2)
The second process 102 of the first embodiment may be changed as follows. As shown in FIG. 2, the contactless charging apparatus that has finished charging is processed and then delivered from the contractor to the customer (first process 201). That is, the contractor sells the power storage device to the customer. The contractor performs the processing at this time. The contactless charging device used in the present invention is easy to process, and processing such as separation of the battery part can be performed without special expertise. Therefore, the contractor can process the contactless charging device.

As in the first step 101 of the first embodiment, the first step 201 in the present embodiment may be sent even if the operator carries the contactless charging device directly to the contractor. Then, installation work of a non-contact charging device is performed. The installation work is performed by the operator or contractor when the operator carries the contactless charging device directly, or by the contractor when it is sent.

Next, as in the second process 102 of the first embodiment, the power storage device that has been charged and processed by the contractor is delivered from the contractor to the customer (second process 202). In this process, the contractor may send the power storage device to the customer, or the customer himself / herself may visit the contractor.

Next, as in the fourth process 104 of the first embodiment, the power storage device after use by the customer is transferred from the customer to the operator (third process 203). The process during this time may be collected directly from the customer by the operator or sent by the customer to the operator. If the customer is a mass retailer or the like, a collection box or the like may be provided in the same mass retailer to improve the efficiency of the collection work. However, this process is not necessary. That is, the power storage device may be sold to customers as disposable.

In the case of the present embodiment, the contactless charging device is processed by the contractor, not the operator, and therefore, an amount commensurate with the processing of the contactless charging device may be added as a reward to the contractor. In addition, a part of the profit from the power storage device sales may be added to the reward.

By using the configuration of the present embodiment, it is possible to use an electromagnetic field that has not been used so far, and it is possible to generate a new benefit that has not existed before. Further, by using a non-contact charging device as the charging medium, the labor burden during installation work performed by the operator or contractor is less than that of other charging media. The installation work does not require special knowledge. And the contractor can make a profit from this business operator without any particular burden. And the customer base can be targeted at traders or general households who use electricity, and because it is very wide, it can be expected to generate great profits.

Furthermore, in this embodiment, since the number of times of delivery of the contactless charging device or the power storage device between the operator, the contractor, and the customer is less than in the case of Embodiment 1, the operator's The burden can be reduced.

(Embodiment 3)
As shown in FIG. 3, after the first process 101 of the first embodiment, the contractor may use the charging energy stored in the contactless charging apparatus (first process 301). At this time, processing of the contactless charging device is not necessary. The contractor may freely install, charge and use the charging energy of the contactless charging device. Further, in the first step 301 in the present embodiment, the operator can directly carry or send the contactless charging device to the contractor in the same manner as the first step 101 in the first embodiment. Good. Then, installation work of a non-contact charging device is performed. The installation work is performed by the operator or contractor when the operator carries the contactless charging device directly, or by the contractor when it is sent.

In the present embodiment, the contactless charging device is then handed over from the contractor to the operator (second process 302). That is, when the contractor does not need to use the contactless charging device, the contactless charging device is returned to the operator. In this process, the contractor may collect the contactless charging device, or the contractor may send the contactless charging device to the provider.

In this embodiment, since the contractor is also a customer, it is not necessary to pay a reward to the contractor. In addition, a rental fee may be collected periodically during the period when the contractor is using the contactless charging device by using the contactless charging device as a rental system. However, if the contactless charging device is sent to the operator at the time of return, the rental fee may be partially deducted or refunded.

By using the configuration of the present embodiment, it is possible to use an electromagnetic field that has not been used so far, and it is possible to generate a new benefit that has not existed before. Further, by using a non-contact charging device as the charging medium, the labor burden during installation work performed by the operator or contractor is less than that of other charging media. The installation work does not require special knowledge. And the contractor can target the business or the general household who uses electricity, and can expect a big profit because it is very wide.

Furthermore, in the present embodiment, the number of times of delivery of the non-contact charging device between the operator and the contractor is smaller than in the case of the first embodiment or the second embodiment. The burden can be reduced. And since the process which processes a non-contact charging device and forms an electrical storage device becomes unnecessary, the burden of this operator can be eased.

In the present invention, the contactless charging device can be installed anywhere as long as an electromagnetic field is generated. For example, a train can be mentioned as one of the installation locations of the contactless charging device. FIG. 8 shows a train vehicle. The train operates by supplying current generated by the potential difference between the overhead line 801 and the line 802 to the motor 804 via the pantograph 803. Therefore, an electromagnetic field is generated by this current in the vicinity of the pantograph 803 and the motor 804. Therefore, when the contactless charging device 805 is installed near the pantograph 803 and the motor 804, charging can be performed efficiently.

Another place where the non-contact charging device is installed is near or inside a home appliance such as a television, a washing machine, or a microwave oven. FIG. 9 shows an example in which a contactless charging device 902 is installed on the top of the display device 901. The contactless charging device 902 may be provided not only on the top of the display device 901 but also on the side, rear, and inside of the display device 901.

When the installation place is near or inside these home appliances, it is desirable that the non-contact charging device is in close contact with a place where daily use is not a problem.

Radio towers used for fishing radio and the like generate electromagnetic waves, and can be charged by installing a non-contact charging device in the vicinity. FIG. 10 shows an example in which a contactless charging device 1002 is installed near the radio tower 1001. The electromagnetic wave emitted from the radio tower 1001 is very strong, and if it is too close, there is a risk of harming the health of the installation worker. Therefore, the installation location of the contactless charging apparatus 1002 may be far from the electromagnetic wave generation source as compared with the example shown in the first embodiment.
