Description

The present invention relates to a portable general-purpose power output device and a system, and more particularly to a portable general-purpose power output device and a system in which the power output unit can be easily increased or decreased.

Conventionally, as described in Patent Document 1, an emergency power output device generally has a storage battery, an inverter, and a battery charger mounted in one frame, and the same equipment other than the inverter is installed in an expansion frame. It is known that the two frames are mounted and mechanically connected by a connecting member that connects the columns of both frames. By increasing the number of frames equipped with storage batteries, it is possible to respond to the increase in power consumption.

However, in the configuration as described above, the storage battery is normally charged by a commercial power source, and DC power is converted from the storage battery to AC power by the inverter unit in the event of a power failure. It ends up. There is a drawback that the number of storage batteries must be increased in order to increase the amount of charge. Further, in the above configuration, each time the number of commercial power output ports increases, the number of frames equipped with a storage battery must be increased, and it cannot be used in an evacuation center where a power supply is particularly required.

In addition, when residents are evacuated, many victims gather at the evacuation center, and the evacuation center does not have facilities for power supply relief. Even if a generator is prepared, it does not meet the needs of the victims who need a power source, and despite the need for speedy response, there is a problem of not knowing where the power source is needed. Especially nowadays, it is no exaggeration to say that mobile phones and smartphones have become a must-have item for most people in their daily lives. Under such circumstances, the few outlets in evacuation shelters are equipped with extension taps and the chargers are bell-shaped. Furthermore, when inpatients who need power for medical equipment are evacuated, the number of people accepted by nearby hospitals is limited, and it is expected that the number of evacuation centers that can handle them will be limited, so securing power is very important. it is conceivable that. In addition, even if an emergency generator is prepared, the capacity is small, and even if the capacity is large, the AC100V outlet and the USB outlet for charging that people need are in short supply.

It is conceivable to arrange a conventional temporary distribution board, but this is mainly for the purpose of supplying the power required during construction at a construction site or the like. In this case, since it is handled by a technician with specialized knowledge and technology, parts such as external wiring connections and wiring connection points and components inside the distribution board are also exposed, which poses a risk of life to the general public. Is. Therefore, in order to install such a temporary distribution board, it was necessary to take off-limits measures and limit the number of operators. In addition, since the housing is made of metal, it is heavy and requires labor and time for transportation. Temporary power sources in emergency evacuation areas can supply only a small amount of power from a small-capacity portable generator with an extension cord, etc., and if a large amount of power is to be supplied, multiple such generators must be prepared. It did not meet the needs of the users.
