The invention relates to a solar battery charging circuit which is used for charging a storage battery and is characterized in that the input end of the solar battery charging circuit is used for connecting with a solar panel, and the output end of the solar battery charging circuit is used for connecting with the storage battery; the solar battery charging circuit comprises a direct current (DC) / direct current (DC) converter and a voltage control circuit unit, wherein the DC / DC converter is used for carrying out power conversion between the solar panel and the storage battery, and filters are respectively connected in series between the DC / DC converter and the output end and between the DC / DC converter and the input end; and the voltage control circuit unit is connected in parallel between the output end and the input end and is used for stabilizing the output voltage of the solar panel. The invention also discloses a solar battery charging device provided with the solar battery charging circuit of the invention and a solar vehicle provided with the charging device. The solar vehicle provided with the solar battery charging circuit of the invention does not need to be charged periodically.
Description
Technical field [0001] The invention relates to a solar battery charging system, in particular to a solar battery charging circuit used in city cars or golf carts. Background technique [0002] The golf carts in the prior art are usually driven by a battery supplied with electricity, and the battery needs to be periodically charged by an AC power source. Therefore, during the use of the golf car, there is an inconvenience that requires frequent charging. In important occasions, the battery needs to be fully charged in advance to prepare for emergencies; and when the solar vehicle needs to be used for a long time, the limited power of the battery cannot meet the demand. [0003] On the other hand, the electric energy used by golf carts or city cars can be replaced by other forms of energy, such as solar energy. Solar energy has an incomparable advantage. The sun shines all over the land, whether it is on land or sea, mountains or islands, and can be directly developed and utilized...
