High-reliability charging control method for satellite lithium ion storage battery

The invention discloses a high-reliability charging control method for a satellite lithium ion storage battery, and relates to the technical field of satellite power supplies. The method is characterized by comprising the following steps that when charging starts, if the whole satellite power does not meet the charging power requirement, a charging regulator automatically regulates a bus; when the whole satellite power meets the charging power requirement and does not reach a set constant voltage value of a storage battery, constant current charging is performed on the storage battery, and the battery voltage is gradually increased; when the battery voltage reaches a set value, constant voltage charging is performed. According to the high-reliability charging control method for the satellite lithium ion storage battery, three-domain control, that is, bus control, charging current control and charging voltage control on the battery can be achieved, and the advantages of being high in reliability is achieved.
