Title: PHOTOVOLTAIC CHARGING CELLPHONE CASE
Abstract:
A photovoltaic charging cellphone case (1), comprising: a photovoltaic panel group (11), a maximum power point tracking circuit (12) and a charging circuit (13). The photovoltaic panel group (11) is configured to convert light energy into electric energy, and the maximum power point tracking circuit (12) is configured to track the maximum power point of the photovoltaic panel group (11) and output the electric energy of the maximum power point to a battery of a device via the charging circuit (13), wherein the maximum power point tracking circuit (12) is connected to the photovoltaic panel group (11). The maximum power point tracking circuit (12) is integrated in the photovoltaic charging cellphone case (1) to track the maximum power point of the photovoltaic panel group (11) so as to realize the maximum power output, so that the charging voltage and current can both be matched reasonably, thereby solving the related problem that a photovoltaic design of a cellphone protection case needs to independently carry a control apparatus, and also shortening the charging time, improving the charging efficiency and enhancing the user experience.
