Lithium battery on-orbit management simulation test method and device

Abstract

The invention provides a lithium battery on-orbit management simulation test method and device. The method comprises the following steps: comparing a binding value corresponding to lithium ion storagebattery pack management software with an expected value, and determining whether the binding value is consistent with the expected value or not; when it is determined that the binding value is consistent with the expected value, executing a preset control instruction on the lithium ion storage battery pack management software to verify the accuracy degree of software logic corresponding to the lithium ion storage battery pack management software; under the condition that the accuracy degree is determined to meet the preset condition, the simulation of the lithium ion storage battery pack management software in different modes is realized by adjusting the parameters of a power supply controller; and verifying whether the lithium ion storage battery pack management software and the batteryperformances of the lithium ion storage battery pack meet on-orbit use requirements or not according to a simulation result. According to the invention, the control of the voltage difference between the single bodies in the charging period of the lithium ion storage battery pack is realized, the whole testing process can be programmed by using automatic software, and the testing efficiency and theautomation level are improved.

Description

technical field [0001] The invention relates to the technical field of spacecraft ground testing, in particular to a lithium battery on-orbit management simulation test method and device. Background technique [0002] For the first time, Dongsan B platform uses lithium-ion battery packs as energy storage power sources. During different orbital stages during the satellite service, the battery pack needs to be charged, discharged, and equalized to meet the energy demand of the satellite. [0003] During the orbit light period, the solar battery array charges the lithium-ion battery pack through the power controller, and the lithium-ion battery converts electrical energy into chemical energy and stores it; can be converted into electrical energy. Lithium-ion battery packs have the characteristics of light weight and large specific energy. However, when charging and discharging a lithium-ion battery pack, there are high requirements for charging and discharging current, ambie...
