Problems solved by technology
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. It is suitable for nickel-cadmium battery packs, but not for nickel-hydrogen battery packs; 3. The circuit adopts single activation mode, and the equipment is huge and complicated; 4. It adopts single relay mode, no redundant design, and poor reliability

Embodiment Construction
[0013] The main function of the nickel-hydrogen battery passivation treatment control unit circuit is to passivate the entire nickel-hydrogen battery pack. Such as figure 1 As shown, it is a schematic diagram of the passivation treatment control unit circuit of the nickel-hydrogen 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. It is designed to be used in series with two independent switches, which can avoid the failure of the battery passivation switch to be disconnected and cause the battery pack to discharge frequently, so as to ensure reliability. The on or off of the passivation switch in the passivation main circuit and the setting of the prohibition of passivation state can be executed through the ground remote control command. Passivation commands are issued by direct remote control commands...

An Mh-ni storage battery passivating control unit circuit comprises a main passivating circuit, a voltage detecting circuit and a comparing and driving circuit. The main passivating circuit comprises two magnetic latching relays and an energy dissipation resistor and controls a passivating switch of a storage battery, and the two magnetic latching relays are connected in parallel. The voltage detecting circuit detects voltage of each battery in a storage battery pack and transmits results to the comparing and driving circuit. The comparing and driving circuit compares detected voltage of each battery with passivating black-out voltage and generates driving signals to transmit to the main passivating circuit to control on and off of the main passivating circuit when detected voltage of any one of batteries is lower than the passivating black-out voltage. By means of single-battery voltage detection and passivation of the integral battery pack, size and weight of the Mh-ni storage battery passivating control unit circuit are reduced, and the Mh-ni storage battery passivating control unit circuit is high in reliability.
Description
technical field [0001] The invention relates to a control unit circuit for controlling the passivation operation of a nickel-hydrogen storage battery. Background technique [0002] 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 the trackable space objects. At present, there are few domestic and foreign researches on the explosion possibility and explosion-proof technology of batteries under abnormal working conditions after satellite de-orbiting. sex and safety. Passivation treatment of batteries has become an important means to improve the safety of batteries. [0003] For passivation treatment, due to the different orbits of satellites and the different working conditions of batteries, ...
