Description
本創作係關於一種太陽能蓄電池之自放電補償電路，尤指一種利用一自放電補償用副蓄電池補償一太陽能蓄電用主蓄電池之電量，使能以充足及有效率電能供電之太陽能控制電路者。The present invention relates to a self-discharge compensation circuit for a solar battery, and more particularly to a solar control circuit that utilizes a self-discharge compensation sub-battery to compensate a solar storage main battery to enable sufficient and efficient power supply.
按，在現今石油供應短缺、油價高漲的時代，各種能源的使用成本皆大幅提高，同時為了環境考量，避免過度排放二氧化碳而造成地球環境的劇烈改變，各方均倡導節能減碳的相關做法，其中利用太陽能發電之方法，就是節能減碳的一種做法。According to the current era of oil shortages and high oil prices, the cost of using various energy sources has increased substantially. At the same time, in order to avoid environmental pollution and avoid excessive emission of carbon dioxide, the global environment has undergone drastic changes. All parties have advocated energy conservation and carbon reduction. The method of using solar power to generate electricity is an approach to energy conservation and carbon reduction.
習用太陽能發電之方式，係利用一太陽能板將光能轉換成電能，再將該電能儲存於一太陽能蓄電池中，之後該蓄電池供應之電源再經由一控制器供電予一負載(用電設備)。然而，一般太陽能光電系統使用之太陽能蓄電池(如：深循環鉛酸蓄電池)易因電池本身自放電現象導致電池之電能自然損耗，加以太陽能板受太陽光強弱不同常造成電壓不穩定，使得蓄電池利用太陽能板充電達到需求電量範圍(即滿充電)的時間大為延長，因而降低了太陽能發電供電的效率，甚或產生負載供電不足之情形。The method of solar power generation uses a solar panel to convert light energy into electrical energy, and then stores the electrical energy in a solar battery, and then the power supplied by the battery is supplied to a load (powered device) via a controller. However, solar cells used in general solar photovoltaic systems (such as deep-cycle lead-acid batteries) are prone to natural loss of battery power due to the self-discharge phenomenon of the battery itself, and the solar panels are often subjected to voltage instability due to the intensity of sunlight, resulting in battery utilization. The time during which the solar panel is charged to reach the required power range (ie, full charge) is greatly prolonged, thereby reducing the efficiency of solar power generation, or even causing insufficient load power supply.
鑑於上述先前技術所衍生的各項缺點，本案創作人乃亟思加以改良創新，並經多年苦心孤詣潛心研究後，終於成功研發完成本案之一種太陽能蓄電池之自放電補償電路。In view of the shortcomings derived from the above prior art, the creator of the case was improved and innovated by the philosopher, and after years of painstaking research, he finally successfully developed a self-discharge compensation circuit for the solar battery of the present case.
