Description

Hybrid energy device, system and method This application claims the benefit of U.S. provisional patent application serial number 62/831,828 filed on April 10, 2019, the entire contents of which are incorporated by reference into this application. The present disclosure relates to energy devices, systems and methods for the same, in particular to devices and systems that integrate hybrid energy sources, such as solar cells and batteries, to provide electrical energy for various uses. Solar energy has been used as a clean and practical energy source for various applications. For example, solar panels can be deployed in sunny locations, such as rooftops, to collect solar energy and convert it into power to supply various electrical devices. Solar panels of various shapes, styles, and sizes have been widely used as energy source components for a wide range of devices, including solar tiles, telephone chargers, residential appliances, and industrial equipment. For example, FIGS. 1 through 3 illustrate some prior art solar energy harvesting systems, shown collectively using reference numeral 10. In the solar energy harvesting system (10) illustrated in FIG. 1, a solar panel (12) or, more specifically, a photovoltaic (PV) panel is used to convert solar energy into electricity and output it to an electronic power converter (14). The electronic power converter (14) converts the received electricity into a usable form for supplying power to a load (16). The electronic power converter (14) is also connected to an alternating current (AC) utility grid (20) via a switch (18). Thus, when the switch (18) is closed, the electronic power converter (14) can output power to the AC utility grid (20) to supply power to various devices (not shown) electrically connected to it, or to use the AC utility grid (20) to supply power to a load (16) when the output of the electronic power converter (14) is insufficient. Energy storage can be used to provide reliability for the system (10). As illustrated in FIG. 2, the prior art system (10) of this example further includes an energy storage device (22), such as a battery assembly, which is connected to a load (16) and an AC utility grid (20) via another electronic power converter (24). By using the battery assembly (22), the system (10) can compensate for the intermittent nature of solar energy output from the PV panel (12) and improve system reliability. FIG. 3 is similar to FIG. 1, but shows a conventional solar energy harvesting system (10) connected to a load (16) and a direct current (DC) utility grid (26) instead of an AC utility grid (20). Conventional solar energy harvesting systems have the following disadvantages and/or challenges: - Unreliability of solar energy generation due to the intermittency of sunlight, - Since the amount of sunlight varies during the day and significantly reduces the overall efficiency of the system, there is a wide range of fluctuation at the operating point of the solar energy harvesting system (e.g., voltage, current, etc.), and - The system generally requires a utility grid to provide resilience. That is, it requires a utility grid to supply power to various loads when solar energy is insufficient or unavailable. Due to these drawbacks and/or challenges, conventional solar energy harvesting systems may not provide optimal solutions for many new applications, such as solar tiles and solar chargers. Consequently, conventional solar energy harvesting systems with suboptimal or even under-optimized performance will have a negative impact on the rapid growth of solar energy systems. Therefore, there is a need for reliable solar energy harvesting solutions. Embodiments of the present disclosure relate to a hybrid energy device or module that integrates a solar cell, a battery cell, and, in some embodiments, an electronic circuit in an efficient and reliable manner, resulting in a reliable energy device or module having high efficiency.
