Background Art

[0002] Satellite batteries are one of the satellite system's energy sources, providing both power and energy storage while the satellite is in orbit. During periods of sunlight, the solar array generates electricity to power satellite equipment and charge the batteries. During periods of insufficient power, the solar array and batteries combine to provide power. During periods of shadow, the batteries release energy to power onboard equipment. Therefore, a combined battery with low mass, compact size, and excellent insulation performance is crucial for the proper operation of satellites.

[0003] A battery consists of a battery shell structure and a cell module. The cell module stores electrical energy, while the battery shell structure is a structural unit containing electrical, mechanical, thermal, and other signal interfaces. These interfaces enable the input and output of electrical energy from the battery. Patent applications for related technologies are constantly being published.

[0004] Chinese patent application 201010538369.X, filed by Aerospace Dongfanghong Satellite Co., Ltd., discloses an octagonal, column-shaped microsatellite with a battery array. The satellite is designed as a non-equilateral, symmetrical octagonal column structure. The octagonal shape and internal space design are optimized, with the satellite divided into two compartments: a platform compartment and a payload compartment. The compartment between the top and middle plates is the platform compartment, while the compartment between the middle and bottom plates is the payload compartment. Each compartment is further divided into three areas by +Y and -Y partitions.

One end of each column is connected to the base plate and the other end is connected to the cover plate, so that the base plate, the cover plate, and the columns form a frame with each other. The cover plate is provided with a plurality of square holes. The base plate, the cover plate, and the plurality of columns are all made of aluminum. A fixing plate is provided in the frame, and fixing plates are respectively provided on opposite sides of the frame in a first direction.
