Description

The present invention is environmentally friendly and can contribute to an energy-saving society by incorporating a power supply system that utilizes hybrid waste batteries (storage batteries installed in scrapped hybrid vehicles) as a power source. Furthermore, the present invention relates to a disaster-responsive vending machine that can not only provide beverages, but also provide emergency power and a Wi-Fi (registered trademark) environment in the event of a disaster.

In recent years, global warming has become a hot topic, and the public and private sectors have come together to promote carbon neutrality (efforts to reduce carbon dioxide emissions that aim to achieve a state in which carbon dioxide emissions and absorption are offset), SDGs (sustainable development goals), etc. This is a theme that should be addressed. Sales of hybrid cars (which are said to emit less carbon dioxide than gasoline cars) are rapidly increasing (sales of one major manufacturer are at 700,000 units/year), and the service life of hybrid cars is 10 years. It is easy to predict that the number of scrapped hybrid cars will increase rapidly in the next 15 years, and as a result, the disposal of the hybrid waste batteries installed in scrapped hybrid cars will become an issue. Waste hybrid storage batteries collected from car dealerships etc. are (a small portion) inspected, sorted and reused, but the majority (despite being reusable) are recycled (turned into raw materials). The current situation is that

On the other hand, in the event of a natural disaster (typhoon, earthquake, tsunami, etc.), the destruction of lifelines such as water, gas, and electricity may be unavoidable; Its value in times of disaster is being reconsidered. In other words, vending machines can be used in times of disaster, such as distributing disaster information on electronic bulletin boards installed in vending machines, and providing beverage cans and other items stored in vending machines (originally for sale) free of charge to disaster victims. Efforts have also begun to contribute to local communities by providing support using the functions of

Patent Document 1 states, ``Providing a vending machine that can switch the operating state of the vending machine depending on the disaster situation, and can also switch to the uninterruptible power supply side as necessary (Patent Document 1) 1: Summary)'' was the challenge, and ``In addition to supplying power from a commercial power source, we will also be equipped with an uninterruptible power supply, and we will always be able to sell products and charge the uninterruptible power supply by supplying power from the commercial power source.'' In a vending machine that is designed to operate, there is a manual operation means for switching from the commercial power supply side to the uninterruptible power supply side when the commercial power supply is stopped due to a power outage, and a manual operation means to switch from the commercial power supply side to the uninterruptible power supply side by operating the operation means. A vending machine characterized in that it is equipped with a control means that detects this and switches to a free vending mode (Patent Document 1: Abstract)'' is disclosed.

Japanese Patent Application Publication No. 2006-195950

The vending machine according to Patent Document 1 (Patent Document 1: Name of the Invention) is a vending machine that “normally sells products by supplying power from a commercial power source and also charges an uninterruptible power supply. According to the statement "Uninterruptible power supply", the uninterruptible power supply is only used in emergencies. When used only in emergencies, it cannot be said that the uninterruptible power supply device (which is considered to correspond to the power supply system in the present invention) is effectively utilized. In view of this current situation, the inventors have developed a power supply system that can utilize hybrid waste storage batteries as a power source for vending machines, thereby saving energy by effectively utilizing waste hybrid storage batteries (which are expected to be discarded in large quantities). We are working diligently to realize a disaster-responsive vending machine that can contribute to the disaster and provide beverages, emergency power, and a Wi-Fi (registered trademark) environment in the event of a disaster. As a result of repeated research and development, the present invention was achieved.

The purpose of the present invention is to contribute to an energy-saving society by incorporating a power supply system that utilizes hybrid waste batteries (storage batteries installed in scrapped hybrid vehicles) as a power source, and furthermore, to An object of the present invention is to provide a disaster-responsive vending machine that can not only provide beverages, but also provide emergency power and a Wi-Fi (registered trademark) environment.

In order to solve the above problems, the invention described in claim 1 aims to reuse discarded hybrid vehicle storage batteries, and also provides not only drinking water but also emergency power in the event of a disaster. , a disaster-responsive vending machine powered by a power supply system capable of providing a Wi-Fi (registered trademark) environment,
Consists of a power supply system and the vending machine itself.
The power supply system includes:
A hybrid waste storage battery with multiple modules arranged,
a charger for charging the hybrid waste electricity storage device;
an inverter that converts direct current generated from the hybrid waste storage battery into alternating current;
The vending machine is characterized in that it is a disaster-responsive vending machine that is equipped with a control device to prevent the hybrid waste livestock battery from becoming overcharged or overdischarged. In this specification, the term "hybrid waste storage battery" refers to a battery that was installed in a scrapped hybrid vehicle, but the "hybrid waste storage battery" actually used in the present invention is limited to this. It is assumed that nothing will happen.

The invention set forth in claim 2 is the invention set forth in claim 1, wherein the vending machine main body includes an emergency power socket and a Wi-Fi (registered trademark) router. It is characterized by being a machine. Furthermore, Wi-Fi (registered trademark) is a method of communication between devices using the IEEE 802.11 standard, which is an international standard (standard for wireless LAN), by the Wi-Fi Alliance (an industry organization based in the United States). This name indicates that the connection has been approved.

The invention set forth in claim 3 is the invention set forth in claim 1, wherein the plurality of modules are all divided into units composed of the same number of modules. This is a characteristic feature.

The present invention is a disaster-responsive vending machine that uses a power supply system that reuses a hybrid waste battery (a battery installed in an abandoned hybrid vehicle) as a power source. Since it is expected that a large number of scrapped (hybrid vehicles) cars will be generated in the future, there is a concern that a large amount of used hybrid storage batteries will be disposed of accordingly. Like conventional lead-acid batteries, they could be exported in large quantities overseas and cause environmental problems. According to the present invention, hybrid waste storage batteries (which would be discarded in large quantities) are utilized as a power supply system, so that the use of hybrid waste livestock batteries in Japan can be expanded without being discarded in large quantities.

The vending machine itself is equipped with an emergency power outlet and a Wi-Fi (registered trademark) router, so even during a power outage blackout, it is possible to not only dispense drinks but also charge mobile phones, etc. It also has the function of a Wi-Fi (registered trademark) base station (a network environment can be established as long as it is within the range of Wi-Fi (registered trademark) radio waves), making it a valuable social infrastructure in times of emergency. It is what it is.

The discarded hybrid waste storage battery (which was installed in a hybrid vehicle) had 28 modules arranged in series and generated a voltage of 200V. Now, in order to equalize the performance of each unit, we will divide the multiple (28) modules into 4 units, each consisting of the same number (7) of modules (arranged in series), and reuse them. ing. In other words, a hybrid waste storage battery consisting of 28 modules is arranged in series every 7 modules (in order to divide into 4 units to make 4 units), and a voltage of 48V is applied to each unit (inexpensive commercially available equipment can be used). A configuration is adopted in which this occurs. With such a configuration, even if some modules of some units deteriorate over time, the damage can be reduced by covering the effects with other units. Note that modules that have deteriorated over time (to the extent that quality cannot be maintained) may be replaced as a unit, or only modules that have deteriorated over time may be replaced.

FIG. 2 is a diagram for explaining the structure of a hybrid waste storage battery. FIG. 2 is a diagram for explaining a power feeding system. FIG. 3 is a diagram for explaining replacement of a hybrid storage battery that deteriorates over time.

<Configuration of disaster-responsive vending machine using hybrid waste storage batteries>
Hereinafter, one embodiment of the disaster-responsive vending machine 1 according to the present invention will be described in detail based on FIGS. 1 to 4. FIG. 1 is a schematic diagram of a disaster-responsive vending machine 1 and a detailed diagram of a power supply system 2 according to the present invention. FIG. 2 is a diagram for explaining the structure of the hybrid waste storage battery 4. As shown in FIG.

As shown in FIG. 1, the disaster-responsive vending machine 1 includes a power supply system 2 that is compact enough to be installed on the vending machine main body 3. (Note: Although the power supply system 2 is compact enough to fit on top of the vending machine body 3, it has excellent performance and can supply power for about 6 hours.)

The power supply system 2, which is the core of the disaster-responsive vending machine 1, consists of a hybrid waste storage battery 4 (for details of the hybrid waste storage battery 4, see Figure 2) in which a plurality of modules (consisting of a plurality of cells) are arranged. , a charger 5 for charging the hybrid waste storage battery 4, an inverter 6 for converting direct current generated from the hybrid waste storage battery 4 into alternating current, and a hybrid waste storage battery 4 that does not enter an overcharged state or an overdischarged state. It is equipped with a sequencer 7 that controls the voltage. Further, the vending machine main body 3 includes an emergency power outlet socket 8 and a Wi-Fi (registered trademark) router (not shown). In addition, to check the initial settings related to the power supply system 2 and the status of the power supply system 2 such as the amount of electricity stored in the hybrid waste storage battery 4 (displayed as a percentage of battery capacity), current, voltage, temperature, etc., charging time and discharging time, etc. This can be performed on the liquid crystal screen (main screen, drive status monitor screen, setting screen, etc.) of the inverter 6 (operation can be performed by touching the touch panel) (see FIG. 1).

The hybrid waste storage battery 4 installed in the hybrid vehicle (before being utilized in the disaster-responsive vending machine 1 according to the present invention) has 28 modules arranged in series as shown in FIG. Furthermore, one module is composed of six 1.2V cells (one unit of battery) (1.2V x 6 cells = 7.2V).

When utilizing the hybrid waste storage battery 4 in the disaster response vending machine 1, the hybrid waste storage battery 4 (as installed in the hybrid vehicle) will be modified. Specifically, 28 modules (of the hybrid waste storage battery 4) are grouped into 7 modules and arranged in series, that is, the 28 modules are divided into 4 and utilized as 4 units. With this workmanship, the plurality of modules that make up the hybrid waste storage battery 4 of the disaster-responsive vending machine 1 are all made up of the same number of modules.

<Mechanism of power supply system>
FIG. 3 is a diagram for explaining the power feeding system 2. As shown in FIG. As shown in FIG. 3, the power supply system 2 converts AC power supplied from a power line (AC 100V) into a charger 5 (a rectifier circuit that converts AC to DC, for example, a full-wave rectifier using a diode bridge). The hybrid waste storage battery 4 is charged with direct current (including a circuit, etc.). The DC power (DC48V) charged in the hybrid waste storage battery 4 is converted into AC power (AC100V) by the inverter 6, and used as power for the vending machine main body 3 (of the disaster-responsive vending machine 1). The hybrid waste storage battery 4 is divided into 4 units with 7 modules as one unit, so that DC can be supplied from each divided unit (see Figure 3: Electric power is 4 units). source)

The power supply system 2 directly supplies AC power supplied from the power line (AC 100V) to the vending machine main body 3 (of the disaster-responsive vending machine 1) without passing through the hybrid waste storage battery 4. The circuit is designed so that it can also be used (see Figure 3). By adopting a switching inverter (which can switch between AC and DC), AC power from the power line (AC100V) is directly supplied to the vending machine body 3 (of the disaster-responsive vending machine 1). When doing so, it is also possible to supply the vending machine main body 3 as AC power from the power line.

The power supply system 2 is charged using cheap late-night power and discharged during the day. That is, the hybrid waste storage battery 4 is charged during the late night electricity hours (for example, from 11 p.m. to 4 a.m.), which is a time period, and discharged during the daytime (for example, from 10 a.m. to 4 p.m.). It will be done. Therefore, it is possible to "cut" the power used during peak periods when a lot of power is used, reduce the amount of power used itself, level out the power demand (power peak cut), and reduce the power demand (disaster response automatic By reducing the running cost of the vending machine body 3 (of the vending machine 1), it is possible to contribute to a reduction in electricity costs.

The power supply system 2 is characterized in that it is controlled by a sequencer 7 (which can control an output circuit according to predetermined conditions (program) depending on the state of a signal from an input device), which is a control device. Specifically, the sequencer 7 monitors the amount of electricity stored in the hybrid waste storage battery 4 (displayed as a percentage of battery capacity: see Figure 1), and issues an instruction (see Figure 3) to the inverter 6 (sends an electrical signal). , it is possible to prevent the hybrid waste storage battery 4 from deteriorating over time due to overcharging and overdischarging.

In order to prevent the hybrid waste storage battery 4 from deteriorating over time due to overcharging and overdischarging, a value 10% to 20% lower than the (set) upper limit of the amount of stored electricity, and 10% to the lower limit of the lower limit of the amount of stored electricity (set) The amount of electricity stored in the hybrid waste storage battery 4 is controlled so that it is between the 20% upper value. However, the difference between the (set) power storage amount upper limit value and the (set) power storage amount lower limit value is defined as 100%. The upper limit value of the amount of electricity stored and the lower limit value of the amount of electricity stored can be arbitrarily set (taking into account the state of deterioration over time of the hybrid waste storage battery 4).

A mechanism for preventing the hybrid waste storage battery 4 from deteriorating over time due to overcharging and overdischarging will be explained in more detail. For example, if the (set) upper limit for the amount of electricity stored is 9WH and the (set) lower limit for the amount of electricity stored is 6WH, then the difference between the (set) upper limit for the amount of electricity stored and the (set) lower limit for the amount of electricity stored (3WH) is defined as 100%, so the lower value of 10% to 20% of the upper limit of electricity storage amount = 8.4WH to 8.7WH, the upper value of 10% to 20% of the lower limit of electricity storage amount = 6.3WH to 6 .6WH.

Furthermore, as a measure against high temperatures in the summer (the sequencer 7 monitors the temperature (not only the voltage) of the hybrid waste storage battery 4), a cooling blow (in conjunction with the sequencer 7) is supplied to cool the hybrid waste storage battery 4. It will be incorporated into System 2. Furthermore, a ventilation fan (in conjunction with the sequencer 7) can be installed in the box in which the power supply system 2 is installed to prevent heat from building up.

FIG. 4 is a diagram for explaining the replacement of the hybrid waste storage battery 4 that deteriorates over time. The hybrid waste storage battery 4 has 28 modules arranged in series in groups of 7, that is, the 28 modules are divided into 4 and utilized as 4 units. The voltage of 200V (when installed in a hybrid car) is divided into four parts and used as a voltage of 48V. As shown in FIG. 4, the quality of the power supply system 2 can be improved by replacing a product (module) that deteriorates over time with a good product (module).

The hybrid waste storage battery 4 has 28 modules divided into four and utilized as four units, so even if some (one of the four units) deteriorates over time, the other four units will not. The structure is such that three of them can cover that amount. In other words, it is possible to reduce the risk of high voltage, and furthermore, the units can autonomously complement each other to keep the voltage uniform and achieve stable charging and discharging. (Deterioration over time has progressed to the extent that quality cannot be maintained) When the units are no longer able to autonomously complement each other to maintain uniform voltage and achieve stable charging and discharging, deterioration over time Quality can be maintained and improved by replacing the product with a good product (see Figure 4).

The voltage of 48V is due to the fact that power devices (equipment used to control and supply electrical energy) are inexpensive, and the technology to be adopted is easy, such as because the power supply voltage is 48V, which reduces the circuit current and reduces the weight of the wire harness. Considering the cost of sheath parts, it can be said that this technology is easy to introduce. In addition, by measuring the voltage of each module constituting the hybrid waste storage battery 4 through a charge/discharge test, replacing modules that have deteriorated over time, and recombining so that the voltage performance of each unit is also the same, the hybrid waste storage battery 4 There is very little variation in voltage during charging and discharging, making it possible to obtain stable quality.

It is also possible to increase the power storage capacity of the hybrid waste storage battery 4. Specifically, this can be achieved by installing four hybrid waste storage batteries 4 (one battery has a capacity equivalent to one hybrid vehicle). Taking advantage of the advantages of hybrid waste storage batteries 4 (which are low-cost batteries), increasing the number of batteries installed and using them not only for vending machines but also as emergency power sources for offices (100V AC: lighting, air conditioners, personal computers). Can be done. Furthermore, we are considering using it as a factory power source (factory auxiliary power source: AC200V) (as an inexpensive and reliable power source).

<Effects of disaster-responsive vending machines>
Although the number of discarded hybrid storage batteries 4 is increasing rapidly due to the rapid spread of hybrid vehicles, the current situation is that only a portion of them are being reused for replenishing vehicles. As a large amount of hybrid vehicles are disposed of, it is expected that a large amount of (installed) hybrid waste storage batteries 4 will also be disposed of. Furthermore, like lead batteries, they may be exported in large quantities overseas, causing environmental problems.

The present invention not only makes it possible to accelerate the reuse of the hybrid waste storage battery 4, but also contributes to energy saving in various electrical products such as vending machines etc. by utilizing it as the power supply system 2. be. Furthermore, it can also be used as an office power source or a factory auxiliary power source.

The disaster-responsive vending machine 1 can provide beverage cans and charge mobile phones during power outages (blackouts), and is equipped with a Wi-Fi (registered trademark) router and functions as a mobile base station. . Therefore, it has great social significance as it functions as valuable infrastructure in times of emergency. The disaster-responsive vending machine 1 can reduce costs by cutting power peaks during the day and saving energy, and can also be used as an emergency power source during power outage blackouts. The power supply system 2 is equipped with a mechanism that can control the voltage of the hybrid waste storage battery 4 with the sequencer 7 and prevent aging deterioration due to overcharging and overdischarging (of the hybrid waste storage battery 4). It can extend the lifespan.

Since the power storage capacity is proportional to the number of hybrid waste storage batteries 4 installed, the more the number of installed hybrid batteries 4 is increased, the more the advantage of the low-cost hybrid waste storage batteries 4 can be utilized. For example, by increasing the number of installed hybrid waste storage batteries 4 (the capacity of one is equivalent to one hybrid car), it can be used as an emergency power source for offices, etc. (28 modules x 4 units) You will be able to do this. Furthermore, we are considering using it as a factory power source (AC200V).

The hybrid waste storage battery 4 (installed in a hybrid vehicle) had multiple (28) modules connected in series to generate a voltage of 200V. Due to the series arrangement, even if one module deteriorated over time, the storage battery itself could no longer be used.However, in the present invention, the battery for one vehicle (installed in a hybrid vehicle) is divided into four 50V units. , high voltage risks can be reduced accordingly. Furthermore, the units can autonomously complement each other to maintain uniform voltage and enable stable charging and discharging.

<Example of changes to disaster-responsive vending machines>
The disaster-responsive vending machine according to the present invention is not limited to the aspects of each embodiment described above, but includes a power supply system, a vending machine main body, a hybrid waste storage battery, a charger, an inverter, a sequencer, and an emergency power source. The configurations of the electrical outlet, the Wi-Fi (registered trademark) router, etc. can be changed as necessary without departing from the spirit of the present invention. For example, instead of using a sequencer as a control method for the power supply system, a microcomputer may be used as the control method. If more detailed control is required to improve energy efficiency, AI (artificial intelligence) technology can be adopted. It goes without saying that the power supply system is not limited to the waste hybrid storage batteries installed in hybrid vehicles, but can also utilize storage batteries installed in electric vehicles (EVs). None.

The disaster-responsive vending machine according to the present invention has excellent effects as described above, so it is environmentally friendly and can contribute to an energy-saving society, and can not only provide drinking water in times of disaster, but also It can be suitably used as a disaster-responsive vending machine that can provide a power source and also a Wi-Fi (registered trademark) environment.
