Description
本發明係關於一種儲電模組，特別係關於一種可提升儲電效率之複合式儲電模組。The invention relates to a power storage module, in particular to a composite storage module capable of improving storage efficiency.
再生能源是目前世界各國積極投入研發的替代能源，而再生能源中又以太陽能及風能之能源技術開發為主要範疇。習知太陽能或風能之使用必須先透過儲電裝置將其所產生的電能予以儲存，再運用至其它用電產品或設備。如美國公告專利第US7,545,117號所揭示之「二級式能源儲存裝置(Two Stage Energy Storage Device)」，其係先累積間歇性及變動性的能源至一第一級能源儲存裝置，之後，再透過一充電管理組件儲存至一第二級能源儲存裝置，此外，其係可在太陽能電池之輸出電流過大時，經由過電壓釋放機制來保護該第一級能源儲存裝置。Renewable energy is an alternative energy source that is actively invested in research and development in the world, and renewable energy is mainly developed with solar energy and wind energy technology.

No. 7,545,117, which first accumulates intermittent and variability energy to a first-level energy storage device, after that, The second level energy storage device is stored through a charge management component. In addition, the first level energy storage device can be protected via an overvoltage release mechanism when the output current of the solar cell is excessive.
然而，上述習知技術係採用單一充電路徑，其不論強日照或弱日照，太陽能電池所產生的電能皆需先儲存至該第一級能源儲存裝置，再輸出儲存至該第二級能源儲存裝置，此舉將造成額外的電能消耗。此外，一旦啟動過電壓釋放機制，太陽能電池所產生的大電能將無法被儲存，儲電效率將因此而大幅降低。故有必要提供一創新且具進步性之複合式儲電模組，以解決上述問題。However, the above-mentioned prior art adopts a single charging path, and the electric energy generated by the solar cell needs to be stored in the first-level energy storage device before being output and stored to the second-level energy storage device, regardless of strong sunlight or weak sunshine. This will cause additional power consumption. In addition, once the voltage release mechanism is activated, the large amount of electrical energy generated by the solar cell will not be stored, and the storage efficiency will be greatly reduced. Therefore, it is necessary to provide an innovative and progressive composite storage module to solve the above problems.
