Problems solved by technology
During the in-orbit flight of the spacecraft, especially the deep space exploration spacecraft, before the active solar wing is deployed, and during the power drop and landing shock process of the outer space and the soft landing, the solar wing is in the retracted state. Once the battery pack is discharged If the switch is disconnected abnormally, there is a risk that the entire spacecraft will not be able to be powered on again after a power outage, making the entire mission fail

Embodiment Construction
[0019] The present invention will be further described below in conjunction with the description of the drawings and specific embodiments.
[0020] Such as figure 1 As shown, an on-orbit anti-power failure system for a spacecraft battery includes a battery pack 1 and a power controller 2, and the power controller 2 includes a discharge switch relay K connected in series to the battery bus + of the battery pack 1, so The two ends of the discharge switch relay K are connected in parallel with an anti-power-off protection circuit, and a storage battery discharge circuit is newly built outside the discharge switch relay K.
[0021] Such as figure 1 As shown, the meter meter anti-power-off protection circuit includes a meter meter 3 and a short-circuit plug 4 inserted on the meter meter 3. The short-circuit plug 4 is also called the meter meter anti-power-off protection plug. The meter meter 3 passes through The wire is connected in parallel with the discharge switch relay K.

The invention provides an on-orbit anti-power failure system for a spacecraft battery, comprising a battery pack and a power controller, the power controller includes a discharge switch relay K connected in series with the battery bus of the battery pack, and the discharge switch relay The two ends of K are connected in parallel with an anti-power-off protection circuit of an instrument meter. The invention also provides an on-orbit power failure prevention method for the spacecraft storage battery. The beneficial effect of the invention is that it can realize the uninterrupted and safe power supply of the spacecraft during the whole internal power transfer process, and ensure the safety of the energy system of the spacecraft.
Description
technical field [0001] The invention relates to spacecraft, in particular to an on-orbit power failure prevention system and method for a spacecraft battery. Background technique [0002] In the current spacecraft power supply and distribution link design, the battery pack is connected to the bus through a discharge switch to supply power to the entire spacecraft load. During the in-orbit flight of the spacecraft, especially the deep space exploration spacecraft, before the active solar wing is deployed, and during the power drop and landing shock process of the outer space and the soft landing, the solar wing is in the retracted state. Once the battery pack is discharged If the switch is turned off abnormally, there is a risk that the entire spacecraft will not be able to be powered on again after a power failure, making the entire mission fail. Contents of the invention [0003] In order to solve the problems in the prior art, the invention provides an on-orbit power fa...
