Micro-satellite open power supply and distribution subsystem

Abstract

The invention provides a miniaturized satellite open power supply and distribution subsystem comprising a folding flexible solar cell array 1, a multi-DOF solar cell array 2, a lithium polymer battery set A31, a miniaturized charging-discharging management module A41, a miniaturized charging-discharging management module B42, a lithium polymer battery set B32, and a highly-integrated power distribution management module 5. The folding flexible solar cell array 1, the lithium polymer battery set A31 and the miniaturized charging-discharging management module A41 are connected. The multi-DOF solar cell array 2, the lithium polymer battery set B32 and the miniaturized charging-discharging management module B42 are connected through a cable. The highly-integrated power distribution management module 5 is connected with the miniaturized charging-discharging management module A41 and the miniaturized charging-discharging management module B42. The miniaturized satellite open power supply and distribution subsystem is simple to configure, redundancy design is reasonably performed, system performance is improved, development cost is greatly decreased, and the requirements of the miniaturized satellite power supply and distribution subsystem for small size, light weight and short development cycle can be met.

Description

technical field [0001] The invention relates to the technical field of satellite power supply and distribution, in particular to a micro-satellite open power supply and distribution system, in particular to a 50kg micro-satellite open power supply and distribution subsystem. Background technique [0002] The power supply and distribution subsystem converts light energy or chemical energy into electrical energy through some physical or chemical change, stores, adjusts and transforms it as needed, and then supplies power to each subsystem of the satellite. The power supply and distribution subsystem generally consists of solar cell arrays, battery packs, power controllers, power converters, distributors and cable networks. [0003] Traditional satellite power supply and distribution subsystems usually use rigid substrates for solar cell arrays, which are oriented to the sun through one-dimensional or two-dimensional driving, and are symmetrically installed on the north and sou...
