Description

Technical Field

[0001] The utility model relates to the technical field of energy storage, in particular to a cascade type high-voltage home energy storage system. Background Art

[0002] At present, as the European and American markets are increasingly in need of high-power electricity for villas, home storage inverters generally need to be configured with single-phase or three-phase power supply of more than 10kW (split phase in North America). From P=U*I, it can be seen that if the battery interface still uses a low-voltage interface of about 51.2V, when the 10kW inverter is working at full power, the current at the battery interface will reach more than 200A; the large current increases the system safety risks, reduces the system efficiency, and increases the cost of connecting cables. From the selection of inverters in the industry, we can also see a consensus feature of inverter industry products: for home storage inverters >10kW, the battery interface voltage range is mostly high voltage (for example, 120~600V). At this time, a high-voltage home storage PACK is required for use. Compared with low voltage, high-voltage home storage systems are safer, more stable, and have higher system efficiency.

[0003] New energy home energy storage modules use lithium battery packs of certain specifications to store currently unused or excess electrical energy, and then extract it for use during peak usage, or transport it to places where energy is scarce for use. Lithium battery packs are increasingly used in communication base station energy storage, home energy storage, and industrial and commercial energy storage. In new energy home energy storage modules, battery modules are needed to store electrical energy. However, modules in the home storage market have the following problems: the integrated structure of the module and the cabinet makes the overall battery system bulky, inconvenient to move during use, and inconvenient to carry and install; the high-voltage system cabinet has no heat dissipation structure; there is no drainage structure in the high-voltage system cabinet; therefore, how to overcome the above-mentioned technical problems and defects has become a key issue that needs to be solved.
