Energy storage equipment is simply an energy storage device, which is composed of important components such as energy conversion system, energy storage system, energy management system and safety system. The energy storage machine can store excess electricity and be used during peak power consumption, temporarily used in an environment where power is off or outdoor power is off, or transported to places where energy is scarce. It can meet people's electricity demand in terms of time and space, and make the use of electric energy more reasonable and efficient. Energy storage equipment is divided into household energy storage, industrial and commercial energy storage, large-scale energy storage, common in life are mobile power, energy storage batteries, household energy storage machines and so on. Through market research and combined with the needs of users, designers carry out design innovations from various aspects such as modeling, color, material, craftsmanship, and man-machine. Determine the overall structural framework of the product, optimize the configuration of each component, ensure that the technical parameters of all aspects of the product meet the standards, and ensure the stability, reliability and safety of the product. The appearance design is small and simple, easy to carry; streamlined design style, strong stereoscopic impression; good material selection, aluminum-shaped body design, exquisite surface treatment, rounded angular curved surface design; color matching is mainly classic black, highlighting the high-end atmosphere; The handle design is simple and the hand-held comfort is high. In terms of functional use, the user's needs and habits are fully considered. The overall design is ergonomic, the body structure is compact, the operation is simple and convenient, the applicability is strong, and it has a good user experience.
