[Industrial applications]

 The present invention is a charging device and a charging device that can charge a nickel-cadmium battery pack for DC-powered electrical equipment, which is mainly used outdoors, with a solar battery easily and without being restricted by the voltage of the battery pack. The present invention relates to devices such as mobile communication devices and consumer electric devices that are equipped with devices.

[0002]

[Prior art]

 Electric equipment mainly used outdoors is equipped with a battery pack in its housing as a power source, and this battery pack is used by being pre-charged by a commercial power source or a charger using a car battery as a power source. Although the battery pack wears down as the electric equipment is used, it cannot be recharged while the electric equipment is in use outdoors where it is difficult to secure a power source for charging. You must carry a battery pack. Therefore, especially when used outdoors for a long period of time, engine generators are used.

On the other hand, conventionally, for example, a mobile phone disclosed in Japanese Utility Model Laid-Open No. Sho 63-169740 has been proposed as an electric device mainly used outdoors. This mobile phone has a solar cell attached to a portable handset and uses the power from the solar cell for the main circuit power supply and its charging.

 However, the above-mentioned conventional techniques have the following problems. That is, when using an electric device in the field without a power source for charging as described above, it is necessary to carry a large number of spare battery packs that have been charged in preparation for a dead battery. Therefore, it takes time and effort to charge the spare battery packs, and it is inconvenient to carry them with you. Furthermore, it is not practical to prepare an engine generator for long-term outdoor use because it requires a large amount of equipment. There is also a solar cell used for charging a battery pack, but this is one in which a battery pack is charged through a conventional charger, and the types of battery packs that can be charged are limited, making it versatile. There is no.

On the other hand, in a portable device such as a conventional mobile phone in which a solar cell is attached to a handset, a charger for adjusting the photoelectrically converted electric power to a secondary battery charging standard in addition to the solar cell, and There is a problem in that the structure for making electrical connections to the device, the lead wires, etc. need to be incorporated into the device, and the structure is complicated, and the weight increases and the operability deteriorates. In addition, in order to charge the secondary battery, it is necessary to expose the handset itself, which is equipped with a solar cell, to sunlight, and it is not possible to charge it in a car or room where the amount of light is low. Was becoming. Furthermore, since the solar cell, charger, etc. are specially used for incorporation into the handset, there is a problem that they cannot be applied to charging conventional equipment.

Therefore, in view of the above conventional circumstances, the present invention aims to provide a charging device that uses a solar battery as a charging power source and charges the battery pack with the electric power generated by the solar battery.
