Abstract

The invention discloses a self-adaption charge control system and method of a storage battery charging circuit. The control system comprises an output voltage sampling module, an output current sampling module, a comparison control module, a constant-voltage loop control circuit, a constant-current loop control circuit, a minimum taking mode circuit and a driving circuit. The self-adaption chargecontrol system can solve the technical problem that a traditional charging circuit can only charge a single storage battery pack in the field of spaceflight.

Description

technical field [0001] The invention relates to the technical field of space energy management, in particular to a battery charging circuit adaptive charging control system and method. Background technique [0002] As the core component of the spacecraft, the main task of the spacecraft energy system is to provide high-quality, high-reliability continuous power supply for the spacecraft during flight to meet the power requirements of various missions and loads. [0003] Traditional charging regulators for space battery packs only charge battery packs with a fixed voltage range, and cannot charge battery packs with different numbers of strings. With the development of aerospace technology, the increase of load types, and the difference in battery voltage levels, higher requirements are put forward for adaptive charging circuits and their control methods. [0004] At present, the voltage levels of battery packs commonly used in space include 1 string of lithium-ion batteries ...
