Next, embodiments of the present invention will be described in detail with reference to the drawings.

(Embodiment 1)
1 and 2 show the first embodiment of the present invention. In FIG. 1, reference numeral 101 indicates an AC power source as a commercial power source. As the AC power supply 101, for example, a single-phase AC power supply is used. The AC power supply 101 is supplied to the power conversion device 35. The power conversion device 35 has a function of converting AC power into DC power, and is composed of, for example, an AC-DC converter. The AC-DC converter has a function of converting AC power input by switching control into DC power. AC-DC converters are manufactured using next-generation power semiconductor devices such as SiC (silicon carbide) semiconductor devices and GaN (gallium nitride) semiconductor devices in order to improve the conversion efficiency when converting AC power to DC power. Has been done. Since these semiconductor elements have heat resistance, it is possible to simplify the cooling structure of the AC-DC converter.

As shown in FIG. 1, the power converter 35 has an input terminal T ₁ of the battery module 1 can be connected. The power storage module 1 has a first power storage means 10 and a first quick charge control means 20. The power storage module 1 is equipped with various devices in addition to the first power storage means 10 and the first quick charge control means 20. The DC power supplied to the power storage module 1 via the input terminal T ₁ is controlled to a predetermined voltage and current by the first quick charge control means 20, and then supplied to the second power storage means 10. It has become. Even if the first quick charge control means 20 is integrally designed with the first power storage means 10 to control the voltage and current for quick charge in consideration of the charging characteristics of the first power storage means 10. Well, if such control is possible, the charging characteristics of the first power storage means 10 can be sufficiently taken into consideration by the integrated design, so that highly accurate charging control can be performed, and the first power storage means can be controlled. In addition to being able to extend the life of the product, further safety can be ensured. The first storage means 10 may be of any type as long as it has a function of storing DC power, but in the first embodiment, the storage battery, the electric double layer capacitor, and the lithium ion capacitor are used. It is composed of at least one of them. In the first embodiment, the first power storage means 10 is composed of, for example, only a lithium ion battery in which a large number of cells are connected in series, but in addition to the lithium ion battery, an all-solid-state battery, a double-layer capacitor, and the like. It may be composed of any one of lithium ion capacitors, or may be configured by using these in combination. DC power stored in the first storage means 10 is capable supplied to the load via the output terminal T ₁ (not shown). A first battery management system (BMS) 11 for maintaining a charge balance of a large number of cells constituting the first power storage means 10 is connected to the first power storage means 10.

When the power storage module 1 is incorporated into an electric moving body such as an electric vehicle capable of recovering the regenerative energy generated by braking, the first power storage means 10 should be configured by using a lithium ion battery and a lithium ion capacitor in combination. As a result, it is possible to reduce the voltage fluctuation on the output terminal T ₂ side as compared with the case where the lithium ion battery is used alone. This is because most of the current that goes in and out due to charging and discharging of the first power storage means 10 due to acceleration or deceleration during vehicle operation goes in and out of the lithium ion capacitor, and the amount of energy in and out of the lithium ion battery decreases. To do. Therefore, by configuring the first storage means 10 in combination with the lithium ion battery and the lithium ion capacitor, the load on the lithium ion battery can be reduced and the life of the first storage means 10 can be extended. It will be possible.

A power converter 15 composed of a DC-DC converter is connected to the first power storage means 10. The voltage of the DC power output from the first power storage means 10 can be adjusted by the power converter 15. The power converter 15, is connected to switch voltage regulator (not shown), a voltage corresponding to the application is made possible from the output terminal T _4. As a result, the supply voltage can be adjusted to the optimum value according to the type and function of the electric device, and the capacity of the electric device can be maximized. The temperature of the first power storage means 10 can be detected by the first temperature sensor 12. The output signal K ₄ from the first temperature sensor 12 is input to the charging information processing unit 25. The temperature of the power control unit 21 can be detected by the second temperature sensor 27. The output signal K ₅ from the second temperature sensor 27 is input to the charging information processing unit 25. Charging information processing unit 25 and the AI 26 is capable to exchange information via the signal K _6.

The first quick charge control means 20 has a power control unit 21 and a charge information processing unit 25. The power control unit 21 is composed of a charge control unit 22 and a temperature control unit 24. The charge control unit 22 has a quick charge control function that controls the DC power from the power conversion device 35 to a charge voltage and a charge current suitable for the first storage means 10. The charge control unit 22 has a DC chopper circuit (a DC chopper circuit in which a step-up chopper circuit and a step-down chopper circuit are used in combination) and a current control circuit. The charge control unit 22 has a function of chopper-controlling the DC power supplied from the power conversion device 35 based on the control signal K ₇ from the charge information processing unit 25 and charging the first storage means 10 with the optimum charging voltage. doing. The voltage and current output from the charge control unit 22 to the first power storage means 10 are measured by the output sensor 13, and the signal K ₁ from the output sensor 13 is input to the charge information processing unit 25. Since charging of a lithium ion battery requires particularly high control accuracy with respect to the charging voltage, the first quick charge control means 20 has come to perform high accuracy charge control in consideration of this. The charge control unit 22 has a DC chopper circuit in which a step-up chopper circuit and a step-down chopper circuit are used in combination. A charging program for performing optimum quick charging control for the first storage means 10 based on the detected battery voltage and charging current of the first storage means 10 is input to the charge information processing unit 25 in advance. There is.

The power control unit 21 of the first quick charge control means 20 has a next-generation power semiconductor 23 for power conversion. As the next-generation power semiconductor 23, for example, a SiC semiconductor element, a GaN semiconductor element, a Ga ₂ O ₃ (gallium oxide) semiconductor element, or the like is used, and low loss in use at a high temperature or power conversion is achieved. The next-generation power semiconductor 23 is a package in which these semiconductor elements are covered with an insulating case (not shown), and high power can be controlled by connecting to a related electric circuit. Air E for forced cooling is blown onto the next-generation power semiconductor 23 by the fan 32 shown in FIG. 2 in order to increase the amount of heat dissipated due to power conversion.

The power storage module 1 has a cooling unit 30 for cooling the charging system. The cooling unit 30 is adapted to operate in response to a command from the temperature control unit 24, the temperature control unit 24 are controlled by the output signal K ₃ from the charging processing unit 25. The cooling unit 30 includes a motor 31, a fan 32, and an electronic cooling element 33. The fan 32 is rotationally driven by the motor 31 and blows air toward the cooling surface of the electronic cooling element 33. The electronic cooling element 33 utilizes the Peltier effect, and operates by supplying electric power from the outside. Since the power control unit 21 controls a large amount of electric power supplied to the first power storage means 10 during quick charging, the temperature of the semiconductor element rises. Further, since the lithium ion battery as a cell constituting the first power storage means 10 is stored in a dense state in relation to the storage space, the temperature rises during quick charging. Therefore, the power control unit 21 and the first power storage means 10 are forcibly cooled by the air blown from the cooling unit 30 at the time of rapid charging. In the first embodiment, the cooling structure uses the electronic cooling element 33, but the cooling structure may be such that only the fan 32 is operated, or a water cooling type cooling structure using a heat exchanger may be used.

As described above, by using the next-generation power semiconductor 23 using, for example, a SiC semiconductor element, a GaN semiconductor element, a Ga ₂ O ₃ (gallium oxide) semiconductor element, or the like as the first quick charge control means 20, the first The quick charge control means 20 can be made smaller and lighter, and the first quick charge control means 20 can be remarkably easily mounted in a small space. Further, since the next-generation power semiconductor 23 using these semiconductor elements has significantly higher power conversion efficiency than the power semiconductor using the conventional silicon semiconductor element, heat generation from the first quick charge control means 20 is also generated. The first quick charge control means 20 can be sufficiently cooled even with a simple cooling unit 30 using the electronic cooling element 33 described above.

As shown in FIGS. 1 and 2, the first quick charge control means 20 has an artificial intelligence 26 that optimally controls the charging conditions of the first power storage means 10 based on the charge history of the first power storage means 10. doing. The artificial intelligence 26 is connected to the charging information processing unit 25, and the charging result for each ultra-rapid charging of the first storage means 10 by the first rapid charging control means 20 (charging voltage and charging current during ultra-rapid charging). , Charging time, charging data such as the temperature of the cells constituting the first storage means 10) are stored. The artificial intelligence 26 has a function of calculating the fastest charging time for shortening the quick charging time of the first power storage means 10 while suppressing deterioration of the first power storage means 10 and outputting it to the charging information processing 10 unit 25. Has. That is, the first quick charge control means 20 calculates the fastest charging condition for shortening the quick charging time of the first power storage means 10 while suppressing the deterioration of the first power storage means 10, and the fastest charging condition. It has a function of performing ultra-rapid charging of the first power storage means 10 based on the above. The artificial intelligence 26 may be configured to be connected to the computer main body (cloud) via the Internet, or may be incorporated to the terminal side (edge side). In the first embodiment, the artificial intelligence 26 constitutes a dedicated semiconductor circuit suitable for information processing of the artificial intelligence, and is composed of a semiconductor chip (AI chip) for the edge side for calculating the fastest charging condition. .. In this way, by incorporating the AI chip for the edge side into the first quick charge control means 20, the artificial intelligence 26 can reduce the time required for the calculation process as compared with the case of using the cloud, and can be used for ultra-rapid charge control. It is possible to avoid delays.

Here, the ultra-rapid charging in the present invention means charging in which the time from the start of charging of the first storage means 10 to the arrival of the first storage means 10 at the capacity of 80% is within about 10 minutes. It also includes charging that reaches full charge (charging up to 100% capacity) in a few minutes. Generally speaking, quick charging takes about one hour from the start of charging until the capacity reaches 80%, and the ultra-rapid charging of the present invention has a longer charging time than conventional quick charging. It can be shortened significantly. In the definition of ultra-rapid charging in the present invention, the time from the start of charging of the first storage means 10 to the time when the first storage means 10 reaches the capacity of 80% is limited to, for example, exceeding 80% of the capacity. This is because the state of charge of the lithium-ion battery is close to the saturated state, the acceptance characteristic of the charge is worse than that before the capacity reaches 80%, and the time from the capacity of 80% to the full charge becomes significantly longer. ..

The calculation of the fastest charging condition in the first embodiment is performed by using, for example, a machine learning method using artificial intelligence 26. The artificial intelligence 26 has, for example, an estimation unit that estimates the temperature of the first storage means 10 based on machine learning, and an excessive temperature of the first storage means 10 based on the estimated temperature estimated by the estimation unit. It is provided with a calculation unit for calculating the charging voltage and the charging current, which are the fastest charging conditions for maximizing the charging time of the first storage means 10 while suppressing the increase.

In the learning stage, the estimation unit of the artificial intelligence 26 learns the relationship between the charging conditions (charging voltage and charging current) at the time of ultra-rapid charging in the experiment and the temperature rise of the first storage means 10 caused by the charging conditions. For example, the charging conditions (charging voltage and charging current) at the time of ultra-rapid charging in an experiment conducted using a lithium ion battery of the same type and the same type as the lithium ion battery constituting the first power storage means 10 are used as input teacher data. Using the temperature of the first storage means 10 under the charging conditions as output teacher data, it is possible to learn the relationship between the charging conditions during ultra-rapid charging and the temperature under the charging conditions.

Each cell of the lithium ion battery constituting the first power storage means 10 is forcibly cooled by the cooling unit 30. The temperature rise of the first power storage means 10 during ultra-rapid charging is largely related to the charging voltage and the charging current, and is a factor that accelerates the deterioration of the first power storage means 10. Generally, a battery has a property that the charge acceptance performance improves as the temperature of the battery increases. Therefore, the higher the temperature of the battery, the more current can flow into the battery. As more current flows into the battery, the temperature of the battery becomes higher and higher. Therefore, it is important to precisely control the temperature of the battery during charging.

When the first storage means 10 is actually ultra-rapidly charged, the artificial intelligence 26 receives the charging voltage and charging current of the first storage means 10 sent from the output sensor 13 via the charging information processing unit 25. Entered. The artificial intelligence 26 uses the charging voltage and charging current of the first storage means 10 sent from the output sensor 13 as input data to the estimation unit. When the charging voltage and charging current of the first storage means 10 are input to the learned estimation unit, the estimation unit can estimate the temperature of the first storage means 10 based on machine learning. Based on the estimated estimated temperature, the calculation unit suppresses an excessive temperature rise of the first storage means 10, and is the fastest charging condition for maximizing the charging time of the first storage means 10. The voltage and charging current can be newly calculated. That is, since an excessive temperature rise of the first power storage means 10 promotes deterioration of the first power storage means 10, the first power storage means can be avoided while avoiding an excessive temperature rise of the first power storage means 10. In order to minimize the charging time of 10, the artificial intelligence 26 newly calculates the charging voltage and the charging current, which are the fastest charging conditions, and controls the charging of the first storage means 10. The charging voltage and charging current, which are the fastest charging conditions for maximizing the charging time of the first storage means 10 while suppressing an excessive temperature rise of the first storage means 10, are, for example, the first storage means. It can be a charging voltage and a charging current that can achieve a temperature at which the maximum charge acceptance performance guaranteed by the manufacturer of the lithium ion battery constituting the 10 can be achieved. This is because, if the maximum charge acceptance performance is guaranteed by the manufacturer, there is no or almost no deterioration of the first power storage means 10 even when charging with a large current. In this way, by combining the experimental data and the artificial intelligence 26, it is possible to charge the lithium ion battery ultra-rapidly while suppressing deterioration of the lithium ion battery constituting the first power storage means 10. The first quick charge control means 20 can estimate the life of the first power storage means 10 by grasping the number of charges and the charge result via the artificial intelligence 26. Further, the artificial intelligence 26 has a function of determining whether or not there is an abnormality in the charging current during quick charging based on the current signal K ₂ from the output sensor 14 provided on the output side of the first power storage means 10. When an abnormality in the charging current is determined during quick charging, a command to forcibly stop the quick charging is output to protect the first power storage means 10 from abnormal heat generation and the like.

In the above-mentioned example, it has been explained that the estimation unit of the artificial intelligence 26 estimates the temperature of the first power storage means 10, but the present invention is not limited to this. For example, instead of estimating the temperature of the first storage means 10 by the artificial intelligence 26, the temperature of the first storage means 10 may be actually measured by a temperature sensor or the like. At this time, the estimation unit of the artificial intelligence 26 can be omitted, and the calculation unit of the artificial intelligence 26 suppresses an excessive temperature rise of the first storage means 10 based on the actually measured temperature, and the first The fastest charging condition for making the charging time of the power storage means 10 the fastest can be newly calculated.

Next, the operation and operation of the power storage module 1 according to the first embodiment will be described.
The AC power from the AC power supply 101 is converted into DC power by the power conversion device 35 and supplied to the power storage module 1. The power storage module 1 has a first power storage means 10 and a first quick charge control means 20, and the DC power from the power conversion device 35 is transmitted through the first quick charge control means 20. It is supplied to the power storage means 10 of 1. A part of the DC power from the power conversion device 35 is controlled by the charge control unit 22 of the power control unit 21 in the first quick charge control means 20 to a charge voltage and a charge current suitable for the first storage means 20. Further, a part of the DC power from the power conversion device 35 is supplied to the cooling unit 30 via the temperature control unit 24 in the first quick charge control means 20.

Since the power control unit 21 controls a large amount of electric power supplied at the time of quick charging of the first power storage means 10, the temperature of the power semiconductor 23 in the power control unit 21 rises. Further, since the lithium ion batteries constituting the first power storage means 10 are stored in a dense state in relation to the storage space, the temperature rises due to the charging current during rapid charging. Here, the power control unit 21 and the first power storage means 10 are forcibly cooled by the air blown from the cooling unit 30 at the time of quick charging, and the temperature rise due to the quick charging is suppressed. Therefore, the power control unit 21 and the first storage means 10 The power storage means 10 is operated at an appropriate temperature within an allowable range. Since the first storage means 10 uses at least a lithium ion battery, an electric double layer capacitor, and a lithium ion capacitor, it is possible to improve the fast charge acceptance performance of the first storage means 10 and to improve the storage module. It is possible to shorten the charging time of 1.

Since the first quick charge control means 20 can control the voltage and current for quick charge in consideration of the charging characteristics of the first power storage means 10 by the integrated design with the first power storage means 10, the first quick charge control means 20 is the first. A design that matches the power storage means 10 of 1 with the charge control function can be realized. As a result, the first power storage means 10 can exhibit the expected performance, and the performance of the power storage module 1 can be enhanced. In addition, supplying high-quality power called pure DC power to the load via the output terminal T ₂ makes it possible to design the electric circuit on the load side on the premise that high-quality power is supplied, and ripple. , Noise and surge need not be considered, and the design of the electric circuit on the load side becomes easy. Further, the artificial intelligence 26 of the first quick charge control means 20 determines whether or not there is an abnormality in the charging current during quick charge based on the signal K ₂ from the output sensor 14 provided on the output side of the first power storage means 10. It has a determination function, and when it determines an abnormality in the charging current during rapid charging, it outputs a command to forcibly stop rapid charging and protects the first storage means 10 from abnormal heat generation and the like. Therefore, it is possible to improve the safety and reliability of the power storage module 1 with respect to quick charging.

As described above, the power storage module 1 can suppress deterioration of the power storage performance with respect to quick charging and ensure safety, and the first quick charge control means 20 can be remarkably miniaturized. Therefore, the power storage module 1 can be used in various products. It becomes easy to incorporate into the product, and the efficiency of product handling and business can be improved. Further, since the first quick charge control means 20 has an artificial intelligence 26 that optimally controls the charging conditions of the first power storage means 10 based on the charge history of the first power storage means 10, the first one. It is possible to control charging according to the aged deterioration of the power storage means 10, and it is possible to extend the life of the first power storage means 10 while ensuring safety.

In the first embodiment, the fastest charging condition is calculated using the artificial intelligence 26. However, by providing the first quick charging control means 20 with a charging function instead of the artificial intelligence 26, the artificial intelligence 26 is provided. The fastest charging condition may be calculated without using. When charging of the first storage means 10 composed of a lithium ion battery is started, the remaining capacity (SOC) of the first storage means 10 is usually significantly lower than that at the time of full charging, and the first storage means 10 The terminal voltage has also dropped below the specified value. In a state where the terminal voltage of the first power storage means 10 is significantly lower than a predetermined value, even if the first power storage means 10 is charged with a relatively large current, the first power storage means 10 is hardly deteriorated. It has been known. The so-called conventional CC-CV type charging utilizes this phenomenon. In the present invention, the charge information processing unit 25 of the first fast-charge controller 20 has a function of estimating the remaining capacity of the first power storage unit 10 based on a signal K ₁ and the signal K _2. That is, the charging processing unit 25, and the amount of power flowing into the first storage means 10 based on the signal K _1, the relationship between the amount of power flowing from the first power storage unit 10 based on the signal K _2, first It has a function of estimating the remaining capacity of the power storage means 10.

In the charging information processing unit 25, since the remaining capacity of the first storage means 10 has a certain relationship with the terminal voltage, the terminal voltage of the first storage means 10 is a predetermined value from the remaining capacity of the first storage means 10. It has a function to guess whether or not it is as follows. When the first quick charge control means 20 estimates that the terminal voltage of the first power storage means 10 is equal to or less than a predetermined value from the remaining capacity of the first power storage means 10, the fastest charging program input in advance is performed. Based on the above, it is possible to charge the first storage means 10 for a short time with a large current slightly exceeding the range of the allowable charging current in the case of CC-CV type charging. Each cell of the lithium ion battery constituting the first power storage means 10 is forcibly cooled by the cooling unit 30. The charging information processing unit 25 continuously and finely charges the first storage means 10 for a short time with a large current slightly exceeding the allowable charging current range in the case of CC-CV type charging, and the first It has a function of repeating intermittent charging until the terminal voltage of the power storage means 10 reaches a predetermined value. Here, a large current slightly exceeding the allowable charging current range in the case of CC-CV type charging means a current of about 1.2 to 1.4 times the allowable charging current in the case of CC-CV type charging. Say. As a result, the temperature of the cells constituting the first storage means 10 is maintained within the permissible value despite charging by the large current of the first storage means 10, and the temperature of the first storage means 10 is caused by the rise in the temperature of the cells. Deterioration of 10 is suppressed. As described above, the first quick charge control means 20 has 1.2 to 1 of the allowable charging current in the case of CC-CV type charging until the terminal voltage of the first power storage means 10 reaches a predetermined value. . By continuously performing intermittent charging that charges the first storage means 10 with a large current of about 4 times for a short time, the first storage means caused by the temperature rise without using the artificial intelligence 26. The charging time is shortened while suppressing the deterioration of 10.

As shown in FIG. 8, the ultra-rapid charging station 40A has a second storage means 42 that can be electrically connected to the power storage module 1 and can store power supplied from the outside. In the ultra-rapid charging station 40A, when the power storage module 1 is connected, power can be supplied from the second power storage means 42 to the power storage module 1. As shown in FIG. 8, the ultra-rapid charging station 40A has a rectifier 41 as a second rapid charging control means, a second storage means 42, and a power supply control means 46. An AC power supply 101 is connected to the input terminal T ₅ of the rectifier 41. The rectifier 41 has a function of converting AC power into DC power and charging the second power storage means 42 under appropriate conditions. The second storage means 42 may be of any type as long as it can store DC power, but in the second embodiment, at least a storage battery, an electric double layer capacitor, and a lithium ion capacitor are used. It is composed of any one. The second storage means 42 may be composed of only a lithium ion battery in which a large number of cells 42a are connected in series, or may be configured by using a lithium ion battery and a lithium ion capacitor in combination. An output terminal T ₆ for connecting to an external load side is connected to the output side of the second power storage means 42. A second battery management system (BMS) 43 for maintaining a charge balance of a large number of cells 42a constituting the second storage means 42 is connected to the second storage means 42.

The power supply control means 46 may be configured to employ a switch that instantaneously cuts off the supply of a large amount of power, but in the sixth embodiment, the rectifier 41 as the second quick charge control means is ordered by an external command.

That is, the power supply control means 46 has a function of outputting a power supply stop command signal to the rectifier 41 and controlling the drop of the output voltage of the rectifier 41 at the time of ultra-rapid charging of the vehicle 50. The power supply control means 46 stops the power supply to the second power storage means 42 at the time of ultra-rapid charging of the vehicle 50 as an electric device, and when the vehicle 50 is not super-rapidly charged, the second power storage means Power supply to 42 is allowed. Therefore, the frequency of ultra-rapid charging of the vehicle 50 is extremely low, and power is allowed to be supplied to the second power storage means 42 only during the nighttime hours when the electricity charge is low, and the vehicle 50 is frequently charged. The power supply control means 46 may be provided with a function of stopping the electric power to the second power storage means 42 only during the daytime.

The second storage means 42 of the ultra-rapid charging station 40A has a larger storage capacity than the first storage means 10, and a plurality of storage modules 1A are simultaneously charged by the DC power output from the second storage means 42.

There is. An inverter 47 is connected to the second power storage means 42 of the ultra-rapid charging station 40A. The inverter 47 is connected to a smart meter (not shown) or the like, and converts a part of the DC power stored in the second power storage means into AC power based on a command from an electric power company or the like, and sends it to the power transmission / distribution system side. It has a function to supply. Each device constituting the power storage device 40A is housed in, for example, a storage chamber 49 having the same size as a marine container. Inside the storage chamber 49, the temperature and humidity are adjusted within a certain range by the air conditioner 48 throughout the year.

Next, the procedure and operation of ultra-rapid charging of the vehicle according to the sixth embodiment will be described.
When the vehicle 50 arrives at the ultra-rapid charging station 40A, the vehicle 50 stops at a predetermined position of the ultra-rapid charging station 40A. Before starting the ultra-rapid charging, the operation switch of the vehicle 50 is turned off, and the vehicle 50 is fixed at the stopped position by the operation of the parking brake. After that, the charging plug P1 at the tip of the charging cable 45 connected to the second storage means 42 of the ultra-rapid charging station 40A is attached to the charging connector P2 of the vehicle 50. Just before the charge is started, the control signal K ₈ from the vehicle 50 side to the power supply control unit 46 of the ultra-rapid charging station 40A is output, the power supply from the rectifier 41 by the power supply control unit 46 to the second storage means 42 Is canceled. As a result, the second power storage means 42 is disconnected from the commercial power source 101, and the second power storage means 42 can supply a large amount of electric power for ultra-rapid charging of the vehicle 50.

In this way, the first storage means 10 can be ultra-rapidly charged by using the DC power directly sent from the second storage means 42 of the ultra-rapid charging station 40A, so that the power transmission and distribution system of the electric power company is overloaded. It is possible to avoid becoming a load, and it is possible to significantly increase the electric power for ultra-rapid charging of the first power storage means 10. As a result, the power storage module 1A can be fully charged in a short time, and the efficiency of the charging work can be improved. Further, since the charging time of the power storage module 1A is shortened, it is possible to avoid waiting for charging of the vehicle 50, and it is possible to increase the utilization turnover rate of the ultra-rapid charging station 40A. Further, the power supply control means 46 causes the rectifier 41 to the second storage means by lowering the voltage of the electric power output from the rectifier 41 as the second quick charge control means than the output voltage of the second storage means 42. Since the power supply to the 42 can be stopped, the opening / closing operation by a large switch or the like for shutting off a large amount of electric power becomes unnecessary, the configuration of the ultra-rapid charging station 40A can be simplified, and the configuration is simplified. The reliability of the ultra-rapid charging station 40A can be improved.
