Abstract

The invention discloses a low-light photovoltaic power generation current storage device. The low-light photovoltaic power generation current storage device comprises a photovoltaic panel interface, abooster module, a voltage-division resistor, a first super capacitor, a first control chip, a triode, a second control chip, and an output interface; the booster module boosts the first voltage produced by the photovoltaic panel as the second voltage, the second voltage is used for charging the first super capacitor, and the first super capacitor stores electric energy produced by the photovoltaic panel; the booster module can fully charge the first super capacitor within a certain time; the first control chip sends a signal to the second control chip, the second control chip controls the switch-on of the triode, and the first super capacitor can charge an accumulator through an output interface; the first super capacitor can collect the electric quantity produced by the photovoltaic panel, thereby improving the effective power generation quantity of the photovoltaic panel.

Description

technical field [0001] The invention relates to the technical field of solar photovoltaic power generation, in particular to a low-light photovoltaic power generation accumulator. Background technique [0002] Photovoltaic panel power generation will produce different voltages with different light intensity. When the light intensity is not good, the output voltage of photovoltaic panels is so small that it cannot even charge the battery connected to the photovoltaic panel, resulting in the voltage generated by the photovoltaic panel. Electricity is wasted. [0003] Therefore, there are defects in the prior art and need to be improved. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a current accumulator for low-light photovoltaic power generation, which collects the electric energy emitted by the photovoltaic panel in low light, and improves the effective power generation of the photovoltaic panel. [0005] The...
