Abstract
In order to improve the charging efficiency of a charging apparatus including a photovoltaic generator such as a solar battery, a charging apparatus includes: a battery which is rechargeable; a photovoltaic generator generating electric power in response to received light; and a generative charging portion supplying the electric power generated by the photovolaic generator to the battery. The generative charging portion includes: a control portion which controls current in the direction from the battery to the photovoltaic generator; and a voltage regulation portion which regulates voltage of the electric power supplied from the photovoltaic generator to the battery and is connected to the control portion in series.
Claims9
A charging apparatus comprising:
- a battery which is rechargeable;
- a photovoltaic generator which generates electric power in response to received light;
- and
- a generative charging circuit which supplies electric power generated by the photovoltaic generator to the battery, the generative charging circuit comprising:
- a control portion which controls current in a direction from the battery to the photovoltaic generator;
- and
- a voltage regulation portion which regulates voltage of electric power supplied from the photovoltaic generator to the battery, which is connected with the control portion in series, such that the control portion connects to the battery via the voltage regulation portion, and in which no transistor for charging is included.
A terminal apparatus comprising:
- a main body;
- a battery which is rechargeable and which is arranged inside the main body;
- a photovoltaic generator which generates electric power in response to received light and which is arranged on a surface portion of the main body;
- and
- a generative charging circuit which supplies electric power generated by the photovoltaic generator to the battery, the generative charging circuit comprising:
- a control portion which controls current in a direction from the battery to the photovoltaic generator;
- and
- a voltage regulation portion which regulates voltage of electric power supplied from the photovoltaic generator to the battery, which is connected with the control portion in series, such that the control portion connects to the battery via the voltage regulation portion, and in which no transistor for charging is included.
