Abstract

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 present invention relates to a solar battery charging system, in particular to a solar battery charging circuit for a city car or a golf cart. Background technique [0002] Golf carts of the prior art are usually driven by electric power supplied by batteries, and the batteries need to be recharged periodically by an AC power source. Therefore, during the use of the golf car, it brings an inconvenience that requires frequent charging. On important occasions, the battery needs to be fully charged in advance for emergencies; and when the solar vehicle needs to be used for a long time, the limited power of the battery is difficult to meet the usage requirements. [0003] On the other hand, the electricity 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 on the earth, regardless of land or sea, no matter whether it is a mountain or an island. It ...
