Description

  The present invention relates to a technical field of a power supply device that outputs electric power stored in a plurality of secondary battery modules from an external power supply by an inverter circuit, and a method for assembling the power supply device.

  There is known a power supply device that can be used as an emergency power source (alternative power source) when a power failure occurs or a commercial power source such as outdoors cannot be used. In this type of power supply, when an external power supply is available, the power storage means such as a secondary battery (for example, a lithium ion battery or a lead battery) built in the power supply is charged in advance, and charged as necessary at a later date. By discharging the generated power, it is possible to supply power even in a situation where the commercial power source cannot be used.

  For example, Patent Document 1 discloses a power supply system for disaster prevention that can be charged from an automobile generator and a battery mounted on an automobile. In this patent document 1, since the generator for vehicles and the battery are used as the power supply source, there are problems that vibration and noise are large, and that there is a problem that harmful exhaust gas is generated during power generation.

  Such a power supply device is expected to be highly portable (easy to carry) because it is assumed to be used in a situation where a commercial power supply cannot be used such as when a power failure occurs or outdoors. Therefore, it is required to keep the size and weight small (compact) and to have durability and reliability that can operate in various environments such as temperature, humidity, vibration, electromagnetic waves, and moisture. In the above-mentioned Patent Document 2, although the components of the power supply device are disclosed as a conceptual block configuration diagram, what is disclosed about how these components are actually laid out and realized inside the power supply device. It has not been. Therefore, the response | compatibility with the said request | requirement with respect to a portable power supply device is inadequate.

  The internal layout of the apparatus has a great influence on the size and performance of the power supply apparatus, and is therefore a very important factor in meeting the above requirements. For example, an inverter unit including an inverter circuit for converting DC power to AC generates a large amount of heat, and if the layout is not appropriate, the secondary battery is exposed to a high temperature due to this heat generation, and the battery life is shortened or deteriorated. There is a risk of it. In addition, since the characteristics of the secondary battery depend on the temperature of the operating environment, when a battery module unit consisting of a plurality of secondary battery modules is mounted to increase the charging capacity of the power supply apparatus, Depending on the internal layout, the temperature at which each secondary battery module is exposed may vary, and the deterioration of a specific secondary battery module may progress (the degree of deterioration of each secondary battery module varies, May be lost, and the performance of the entire module unit may be reduced).

  Moreover, since such a power supply device is assumed to be used in various environments such as temperature, humidity, vibration, electromagnetic waves, and moisture, an appropriate and efficient layout considering adaptation to such an environment is required. . Further, when mass-producing portable power supply devices in practice, it is also important to improve the manufacturing cost efficiency, so it is necessary to consider the ease of assembly.

It is possible to realize a power supply device having the same. In particular, by arranging the inverter unit adjacent to the battery module unit so as to extend in parallel along the side surface of the battery module unit, the space density inside the device is increased and an efficient layout without waste is obtained.

  Moreover, by disposing a heat shield plate between the battery module unit and the inverter unit, it is possible to suppress or prevent heat generated in the inverter unit from being transmitted to the battery module unit. As a result, the lifetime can be extended by suppressing the temperature rise of each secondary battery module constituting the battery module unit. Furthermore, since the gap space between the battery module unit and the inverter unit can be reduced by the amount that can suppress the temperature increase of the battery module in this way, a more compact and highly portable power supply device can be realized. .
