The invention discloses a solar energy storage system and a method of the solar energy storage system. The system includes a solar battery used as an input power, a single chip and two polymer lithium batteries used as output power; the single chip is respectively and alternatively connected with two polymer lithium batteries, and the single chip is electrically connected with the solar battery; the solar battery is electrically connected with one polymer lithium battery; the single chip detects and controls work of the two polymer lithium batteries, and control one of the two polymer lithium batteries to externally output, and the other one accepts the charging from the solar battery. When a mobile phone and other external loads are charged, the solar battery can also charge the polymer lithium batteries; when voltage of one polymer lithium battery for charging the load is less than 3 V, it can be automatically switched to the other one polymer lithium battery to charge the load; the solar battery can charge the battery after discharging electricity, thus the solar energy is fully used.
Description
technical field [0001] The invention relates to the technical field of solar energy, in particular to a solar energy storage system and a method thereof. Background technique [0002] There are two existing methods of using solar energy to charge mobile phones and other peripherals: the first is to directly boost the voltage of the solar battery to 5V to charge mobile phones and other peripherals; the second is to add A polymer lithium battery is used as a backup battery, the solar battery is boosted to charge the polymer lithium battery, and then the voltage of the polymer lithium battery is boosted to 5V to charge mobile phones and other peripherals. The disadvantage of the first method is: because the sunlight is not stable, the output of the solar cell is also not stable, which leads to the unsustainable charging of the mobile phone and peripheral devices, which happens from time to time. The second one has made great improvements, at least it is stable when charging mo...
