However, the device has the following limitations in use: 1. It is only suitable for the on-orbit activation treatment of batteries in GEO orbit. The purpose is to improve battery performance rather than energy dissipation after the mission, and it cannot be used for passivation at the end of the mission; 2. Suitable for nickel-cadmium battery packs, not for lithium-ion battery packs; 3. Single relay mode, no redundant design, poor reliability

Embodiment Construction
[0014] The main function of the control unit circuit for passivation treatment of lithium-ion batteries is to passivate the cells of lithium-ion batteries. Such as figure 1 As shown, it is a schematic diagram of the control unit circuit for the passivation treatment of the lithium-ion battery of the present invention, which mainly includes a passivation main circuit, a voltage detection circuit, a comparison and a drive circuit. The passivation main circuit is used to control the passivation of the battery. The passivation path of each lithium-ion battery cell is designed with a secondary switch connected in series with a relay and a triode, which can prevent the battery pack from being discharged due to misoperation of the battery passivation switch. Guaranteed reliability. The on or off of the passivation switch in the passivation main circuit and the setting of the passivation prohibition state can be executed through the ground remote control command, and the passivation ...

The invention discloses a passivating treatment control unit circuit of a lithium ion storage battery. The passivating treatment control unit circuit comprises a passivating main circuit, a voltage detecting circuit, and a comparing and driving circuit, wherein the passivating main circuit comprises control channels of which the number is the same as that of single storage batteries in a storage battery group; each control channel is composed of a magnetic latching relay, a switch triode and an energy dissipating resistor which are connected in series, and is used for controlling a passivating switch of the single storage battery; the voltage detecting circuit detects voltage of each single battery in the storage battery group and sends the result to the comparing and driving circuit; the comparing and driving circuit compares the detection voltage of each single battery with a passivating cut-off voltage respectively, when the detection voltage of any single storage battery is lower than the passivating cut-off voltage, generates a driving signal and sends the driving signal to the switch triode of the corresponding control channel for switch on or switch off control. The control unit circuit disclosed by the invention employs the theory of voltage detection of single storage battery and passivating treatment of the whole storage battery group, so that both the volume and weight of the circuit are reduced; and meanwhile, the control unit circuit is very high in reliability.
Description
technical field [0001] The invention relates to a control unit circuit for controlling the passivation operation of a lithium-ion battery. Background technique [0002] The existence of space debris has an increasingly serious impact on spacecraft and space missions, especially increasing the potential hazards of manned spaceflight. Whether it is to protect the space environment, safeguard China's rights and interests in outer space, or improve the life of my country's spacecraft in orbit and ensure the safety of manned spaceflight, it is necessary to strengthen research on the observation, mitigation and protection of space debris. [0003] The battery explosion is the main reason for the disintegration of the satellite in orbit and the generation of space debris. The analysis of the causes of the on-orbit disintegration events of space activities in the past shows that the amount of space debris caused by the explosion of the storage battery accounts for about 2.25% of th...
