Embodiment Construction
[0017] The technical content of the present invention will be further described in conjunction with the accompanying drawings.
[0018] Such as figure 1 As shown in -7, when the light intensity is sufficient, that is, when the photovoltaic battery reaches 13 volts, the light-controlled electronic switch starts the high-current charging module to charge the external battery module; when the light intensity is weak, that is, when the photovoltaic battery is less than 13 volts, The light-controlled electronic switch starts the weak current accumulation module to charge the internal energy storage module through the parallel charging module in series; the internal energy storage module can also start the high-current charging module to charge the external battery module.
[0019] The weak current accumulation module is composed of a supercapacitor array and a thyristor control module. By collecting the weak current generated in a weak light environment bit by bit, the electric ene...

The invention discloses an energy storage type solar weak light charger circuit system. When the light intensity is enough, namely a photovoltaic battery is 13V, a light control electronic switch starts a high-current charging module to charge an external storage battery module; when the light intensity is relatively low, namely the photovoltaic battery is not up to 13V, the light control electronic switch starts a low-current gathering module to charge an internal energy storage module through a series parallel charging module; and the internal energy storage module can simultaneously start the high-current charging module to charge the external storage battery module. The energy storage type solar weak light charger circuit system has the advantages that a general solar charger can perform charging under an insufficient sunshine environment, and low electric quantity generated by a solar battery panel can be collected under a weak light environment; a lithium battery can be used as a built-in energy storage, so that residual electric quantity can be stored in the built-in energy storage, and waste can be prevented; the charger of the circuit can continuously and stably charge the battery; and the time limitation of the conventional solar charger is broken through, the life of people is facilitated, and the use benefit is improved.
Description
technical field [0001] The invention relates to a solar charger circuit, in particular to an energy storage type solar weak light charger circuit system. Background technique [0002] At present, environmental pressures such as global fossil energy resources are increasingly scarce and climate change is increasing. New and renewable energy sources such as solar energy, wind energy, and biomass energy have been regarded as important strategic alternative energy sources by governments around the world. Solar energy is a clean, efficient and inexhaustible new energy source, and it is one of the cleanest energy sources; while photovoltaic power generation has the advantages of safety, reliability, no noise, no pollution, less constraints, low failure rate, and easy maintenance, etc., but due to Restricted by natural conditions such as day and night, seasons, geographical latitude and altitude, and affected by random factors such as sunny, cloudy, cloud, and rain, the solar irra...
