Integrated high-reliability lithium battery intelligent management system

Abstract

The invention relates to an integrated high-reliability lithium battery intelligent management system. The system comprises an analog quantity acquisition unit, an instruction output unit, a communication unit, a central control unit and a power supply management module; the analog quantity acquisition unit acquires real-time working temperature, voltage signals and current signals of a lithium battery; the instruction output unit controls the working mode of the lithium battery according to a control signal; the communication unit receives a control instruction sent by an upper computer and transmits the control instruction to the central control unit; the communication unit receives the voltage signals and the current signals transmitted by the central control unit and transmits the signals to the upper computer; the central control unit converts the control instruction into a control signal and sends the control signal to the instruction output unit; and the central control unit receives real-time working temperature, voltage signals and current signals of the lithium battery and transmits the signals to the communication unit. According to the integrated high-reliability lithium battery intelligent management system of the invention, power supply and charge-discharge management of an equipment bus on a spacecraft in a ground test stage can be realized, and reliable power supply of the equipment bus and remote measurement of power supply parameters in a flight mission period can also be realized.

[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.
