Abstract

The invention relates to a power compensation device based on a solar battery. A charging device is connected with a control circuit or a power control system integrated in an electrical appliance; the charging device is a solar battery. The method includes the following steps: the charging device is connected to the power interface of the electrical appliance, and the electrical appliance performs voltage-current scanning on the output of the charging device through a microprocessor, and when the absolute value of the difference between the detected open circuit voltage value and the set voltage value is less than the threshold value , then the microprocessor gives the switching power supply controller a control signal, so that the switching power supply controller controls the switching power supply to output the output voltage of the charging device to the switching power supply at a set voltage, and the switching power supply uses a fixed voltage value to charge the electrical storage device. The device of the present invention uses a thin-film battery as a power source, and can output a stable voltage to charge electrical appliances, and is widely used in different electrical appliances.

Description

Technical field [0001] The invention relates to a device and method for converting solar energy into electric energy to compensate the power supply of electrical appliances. In particular, it is a device and method that uses solar cells to generate electric energy, and uses integrated circuits or software to manage the power of electrical appliances, so that the battery life of the electrical appliances is increased. Background technique [0002] A solar cell is a device that converts solar energy into electrical energy. When photons enter the solar cell, electron-hole pairs are generated. The electrons and holes are separated and then exported to the positive and negative electrodes of the solar cell to generate voltage. [0003] The use of solar cells to supplement electric power for portable devices is one of the many application fields of solar cells, which can make mobile terminals free from dependence on the external power grid during a longer life cycle. [0004] At present, ...
