Integrated high reliability lithium battery intelligent management system

Abstract

Integrated high-reliability lithium battery intelligent management system, including: analog quantity acquisition unit, command output unit, communication unit, central control unit and power management module; the analog quantity acquisition unit collects real-time working temperature, voltage signal and current signal of lithium battery; The command output unit controls the working mode of the lithium battery according to the control signal; the communication unit receives the control command sent by the host computer and transmits it to the central control unit; the communication unit receives the voltage signal and current signal transmitted by the central control unit and transmits it to the host computer; the central control The unit converts the control command into a control signal and sends it to the command output unit; the central control unit receives the real-time working temperature, voltage signal and current signal of the lithium battery and transmits it to the communication unit. The invention can not only realize the power supply and charge and discharge management for the equipment bus on the spacecraft during the ground test stage, but also can reliably supply power for the equipment bus and remotely measure the power supply parameters during the flight mission.

Description

technical field [0001] The invention relates to an integrated high-reliability lithium battery intelligent management system, and belongs to the technical field of power supply systems for aerospace vehicles. Background technique [0002] At present, the lithium-ion battery in the CZ-4 series servo and measurement system has been verified by the flight test in the domestic research and in-service carrier models; the CZ-7 ground test uses a lithium-ion battery to replace the ground power supply. After the power is transferred, it is completely powered by Lithium-ion batteries provide primary power for the arrow, eliminating the need for analog cables, and the power supply is more authentic during ground testing, while silver-zinc batteries are still used for flight. The XX telemetry system uses lithium batteries as the main battery and has completed its first flight. During the shooting range test, the lithium-ion battery needs to be repeatedly disassembled and disassembled t...

[0002] At present, the lithium-ion battery in the CZ-4 series servo and measurement system has been verified by the flight test in the domestic research and in-service carrier models; the CZ-7 ground test uses a lithium-ion battery to replace the ground power supply. After the power is transferred, it is completely powered by Lithium-ion batteries provide primary power for the arrow, eliminating the need for analog cables, and the power supply is more authentic during ground testing, while silver-zinc batteries are still used for flight. The XX telemetry system uses lithium batteries as the main battery and has completed its first flight. During the shooting range test, it is necessary to repeatedly disassemble and disassemble the lithium-ion battery to charge the lithium-ion battery. Before and after the test, the power output switch operation is required, and the state conversion and state inspection operations during the ground test are added.
