Abstract

The invention discloses a solar cell charger which comprises a solar cell array, a storage battery, two charging circuits and at least one charging part. The charging part is provided with a positive pole output end and a negative pole output end, wherein the positive pole output end and the negative pole output end are respectively used for connecting a positive pole and a negative pole of an external battery to be charged. The charging circuits comprises rectifying circuits, output indicating circuits, charging indicating circuits, charging fully indicating circuits, amplification circuits, bleeder circuits, voltage stabilizing circuits and integration op-amp chips LM324. According to the solar cell charger, electricity can be stored to keep charging currents to be stable in the charging process, charging to a battery can be still carried out when lights are weak, or solar power does not exist, and multiple indicating lights are arranged, various indicating states can be indicated, thus the solar cell charger has good market application prospects. In addition, the solar cell charger is low in cost, high in benefit, high in practical value and further capable of designing and forming a solar charging demonstration instrument which is used for teaching demonstration and has good teaching demonstration effects.

Description

technical field [0001] The invention relates to the field of solar charging, in particular to a solar battery charger. Background technique [0002] Solar energy is a kind of pollution-free green energy. It is economical and practical to use solar panels as a multifunctional battery charger, and it is convenient to carry because of its small size. Its effect is even more obvious for some people who often go to the field to travel, especially to some places where power supply is difficult. [0003] Moreover, the ownership rate of mobile phones in our country is relatively high now. If solar battery chargers are promoted, it will bring considerable economic benefits to the country every year and at the same time protect the environment. Solar battery chargers are used to charge mobile phone batteries. Compared with other solar-powered equipment, the requirements for solar batteries are not high. As long as the voltage can reach 4.5 volts or more, the current can reach 100mA o...
