Description

Technical Field

[0001] The utility model belongs to the technical field of devices for charging or depolarizing a battery pack or for supplying power to a load from a battery pack, classified as IPC H02J7 / 00, and particularly relates to a structural innovation and improvement technology for a satellite battery housing device. Background Art

[0002] Satellite battery housings are crucial components in satellite systems, protecting and securing the battery packs. Their design must consider numerous factors to ensure the safety and stability of the battery packs in the space environment. With the continuous advancement of aerospace technology, we anticipate that more advanced materials and design concepts will be incorporated into the design and manufacture of battery housings.

[0003] Satellite battery packs typically consist of a housing and battery modules. The housing houses power input and output components, primarily used to transfer power to and from the module. A module is a group of cells arranged and assembled in a specific pattern, secured with guide bars welded together or nuts and screws, for both power storage and output.

[0004] The housing effectively protects the battery pack from external environmental influences, such as extreme temperatures, radiation, and micrometeorite impacts in space. Through appropriate structural design, the housing securely secures the battery pack within the satellite, ensuring stability and safety during satellite operation. Some housing designs take the battery pack's heat dissipation requirements into account, employing specialized heat dissipation structures or materials to help dissipate heat during charging and discharging, preventing overheating.

[0005] The structure of a satellite battery pack casing is typically complex, requiring a custom design tailored to the battery pack's shape and size, as well as the satellite's internal spatial layout. Generally speaking, the casing consists of multiple components, including a base plate, side panels, a roof plate, and mounting hardware. To meet satellite requirements for weight, strength, corrosion resistance, and radiation resistance, the casing is typically constructed from lightweight, high-strength metal materials such as titanium alloy and aluminum alloy. Furthermore, some casing surfaces undergo special treatments, such as spray-on radiation-resistant coatings, to enhance their radiation resistance.

[0006] Given the high cost of satellite launches, reducing satellite weight is a key approach to lowering launch costs. Therefore, when designing the battery pack casing, careful consideration must be given to its weight, using lightweight materials and optimizing the structural design to reduce weight. The casing must be able to withstand the various forces and vibrations generated during satellite launch, operation, and recovery to ensure the safety of the battery pack. Therefore, thorough calculation and verification of its strength are crucial during design. Battery packs generate significant heat during charging and dissipating. Failure to dissipate this heat promptly can lead to performance degradation or even damage. Therefore, heat dissipation performance must be considered and appropriate heat dissipation measures implemented during the casing design. Satellites contain numerous electromagnetic radiation sources, such as electronic equipment and antennas. Therefore, the battery pack casing must exhibit good electromagnetic compatibility to prevent electromagnetic interference from affecting the battery pack and other satellite equipment.

[0007] Patent application 202123169956.9 discloses a reconfigurable power supply array for simulating satellite batteries, including a shell and a battery pack and a power protection board arranged in the shell; the shell is provided with a charging input terminal and multiple discharge output terminals, the number of the battery packs and the power protection boards are both multiple, and the battery packs and the power protection boards correspond one to one; each of the battery packs is connected in parallel, and the power protection board is connected in series with the corresponding battery pack, and each of the power protection boards is electrically connected to the charging input terminal and the discharge output terminal respectively.

[0008] Currently, small-capacity cylindrical cells are typically assembled into battery modules by spot welding current guide bars, while large-capacity prismatic cells are typically assembled by laser welding current guide bars or securing them with nuts and screws. Different battery modules require corresponding battery housing designs. Utility Model Content
