Problems solved by technology

[0002] As a key component of the satellite system, the lithium battery guarantees the power supply demand of the entire star. When some faults occur on the orbit, the lithium battery continues to discharge and output, or the power supply of the battery pack is exhausted, resulting in the failure of the satellite in orbit. The traditional lithium battery The current monitoring method is to transmit the battery pack voltage and related state telemetry to the ground, and then control it after the ground check. This control strategy has the characteristics of low efficiency, poor real-time performance, and error-prone. It can no longer meet the needs of satellite in-orbit applications.

Embodiment Construction

[0015] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.

[0016] Such as Figure 1 to Figure 3 As shown, the management method for the autonomous control of lithium batteries on the satellite of the present invention includes a lithium battery pack 1, telemetry acquisition 2, power on / off command 3, central computer 4, and service unit 5;

[0017] The steps of the management method of autonomous control of the lithium battery on the star are as follows:

[0018] Step 1: Collect battery pack voltage and battery cell voltage periodically, and judge the validity of the collected data, and eliminate invalid data;

[0019] Step 2: Comparing the collected effective data with the set threshold value, according to the corresponding program control strategy, carry out program control management of lithium battery over-discharge alarm;

[0020] Step 3,...

Abstract

The invention discloses a star lithium battery autonomous control management method. The method comprises the steps that 1 the voltage of a storage battery group and the individual voltage of the storage battery group are collected by cycle, and the validity of the collected data is judged to eliminating invalid data; 2 the collected valid data and a set threshold are compared, and according to acorresponding program control policy, lithium battery over-discharge alarm program control management is carried out; and 3 if the voltage of a lithium-ion storage battery group is higher than the voltage of the storage battery group, the threshold is recovered after over-discharge protection, and protection recovery after over-discharge is carried out. According to the invention, the requirementof satellite on-orbit autonomous management is solved; the on-orbit control instantaneity of satellite energy management is improved; and the satellite on-orbit energy security is ensured.
