The present disclosure provides an electronic device protective case which is able to, by means of photovoltaic power generation, alleviate the insufficient capacity of a cell for an electronic device when it is used in the open air, and while an accumulator may be used as a power tank. A charging/discharging controller is used to control a photovoltaic cell panel in the protective case to store electric energy after the photovoltaic conversion in an accumulator, with the electric energy in the accumulator used to charge the electronic device. In addition, electrical connection states between an external data line port and the electronic device protective case as well as a port of an electronic device is controlled by means of a switch assembly, and when the switch assembly is in an ON state, the charging/discharging controller is used to control the accumulator or an external data line port to charge the electronic device.

Electronic device protective case

A photovoltaic device comprising: a base (), a photovoltaic assembly () and a baffle plate (), wherein the photovoltaic assembly is arranged in an inclined manner on the base from bottom up in a direction from front to rear, and behind the photovoltaic assembly, the baffle plate is arranged in an inclined manner on the base from bottom up in a direction from rear to front.
