Background
The satellite power supply controller product is a satellite power supply system power supply and distribution core control single machine, and provides voltage continuous stable high-quality primary bus energy for a whole satellite launching section and an on-orbit flight section through shunting, charging and discharging adjustment control of solar battery energy and storage battery energy. The satellite power supply controls a single product to control charging of a storage battery while shunting and adjusting solar battery energy during an illumination period, and to control discharging of a fully charged storage battery during a ground shadow period, so that the satellite power supply is a key single product for guaranteeing stable supply of energy of each orbit circle of a satellite.
In the primary power supply product, the service life of the storage battery pack is a key single machine for limiting the on-track service life of the primary power supply product, and in order to ensure the on-track service life, the power supply controller product in the primary power supply product is often researched and produced one year before the storage battery pack product, so that the ground storage time of the storage battery pack is shortened. After the production and development of the power supply controller product are finished, the verification test of the charging function and the discharging function is required, and because the matched storage battery pack is not produced yet, the discharging function test is carried out by adopting a programmable power supply mode, and the charging function test is carried out by adopting an electronic load, namely, the charging and discharging functions of the storage battery pack are simulated by adopting the programmable power supply and the electronic load. Because the charging function and discharging function test interfaces of the satellite power supply controller are the same interface, when the two performance tests of the charging function and the discharging function are tested, the power-off operation is needed, and after the replacement of the charging cable and the discharging cable of the interfaces is completed, the other function test is completed by powering on again. Because the development of a single control product is completed by carrying out mechanical, thermal and other environmental test verification, the full-performance verification test of the power supply controller product is carried out before and after the test, the operation is repeated for a plurality of times, the efficiency is low, the operation risks of power-on, power-off and cable replacement are also present, and the damage risk of the interface and the connector thereof is increased due to the repeated plugging of the charge and discharge interface. Meanwhile, after the production of the storage battery pack is completed, interface correctness verification test and charge and discharge function test are also required to be carried out with a power supply controller product, and potential safety hazards exist due to the fact that the storage battery is electrified and plugged in and out for many times. In order to improve the testing efficiency of the charging function and the discharging function of the satellite power supply controller, reduce the frequency and the operation risk of replacing the charging power cable and the discharging power cable, reduce the plugging times of the charging and discharging interface, improve the live plugging of the storage battery, and need the design research work of the storage battery, the access of storage battery simulation equipment (program-controlled power supply and electronic load) and the control switching technology, the technology is beneficial to improving the testing safety of the satellite power supply controller, reducing the testing risk and shortening the testing development time of the product.
