Problems solved by technology

However, if the timing of blocking the charging current is too early, the charging will be completed in the state of not being fully charged, and the capacity that can be taken out from the secondary battery will be reduced, so that the original capacity cannot be exerted.
In this way, in a conventional power supply unit that combines a solar cell and a secondary battery, it is difficult to charge the secondary battery to fully exhibit its performance.

Abstract

The present invention provides a solar cell power supply device and a rechargeable battery solar charging method. The solar cell power supply device is provided with a battery pack connected in series or in parallel with a plurality of rechargeable cells; a solar cell panel having a plurality of solar cells for generating power to charge the battery pack; a charging control portion capable of controlling charging current or charging voltage when the battery pack is charged by the power generated by the solar cell panel; a current detecting portion for detecting charging current of the battery pack; and a voltage detecting portion for detecting battery voltage of the battery pack. The charging control portion is configured to, when the battery pack is brought close to the fully-charged state, cuts off the charging current at predetermined timing for a charging operation stop period, and compare the battery voltage of the battery pack with a predetermined voltage value as a restart voltage value in the charging operation stop period. The charging control portion determines that the battery pack is fully charged if the battery voltage of the battery pack is not less than the predetermined voltage value as the restart voltage value, and cuts off the charging current.

Description

technical field [0001] The present invention relates to a solar battery power supply device capable of storing and utilizing power generated by sunlight in a secondary battery and a charging method of a secondary battery using a solar battery, and particularly relates to a method capable of directly charging a secondary battery without using a DC / DC converter. A solar cell power supply device that connects a solar cell and a secondary battery to stably charge the secondary battery from the solar cell, and a charging method for the secondary battery using the solar cell. Background technique [0002] Considering CO 2 In order to reduce environmental problems such as reduction, a power supply system that stores and utilizes electric power generated using natural energy that does not depend on fossil fuels has been proposed (for example, refer to Patent Document 1). In this power system, such as Figure 35 As shown, the solar cell and the secondary battery are connected via a ...
