Description

technical field [0001] The invention belongs to the technical field of aerospace power supply, and in particular relates to a solar battery satellite carrying device and a battery testing method. Background technique [0002] With the exploration of the universe by human beings, the continuous development of aerospace technology has also brought new challenges to the long-term in-orbit operation of satellites with high precision, high reliability and high stability. The solar cell is the main power generation unit of each satellite, which provides the conversion of solar energy to electric energy when the satellite is in orbit. At the same time other kinds of new space solar cells are also being developed and developed. [0003] Due to the complexity of the space environment, such as space particle radiation, atomic oxygen, geomagnetic substorms, etc., as well as satellite flight orbits, sunlight incident angles, and temperature changes, the final on-orbit output power of s...

Problems solved by technology

[0007] In order to solve the technical problems existing in the known technology, the present invention provides a solar battery satellite carrying equipment and a battery testing method, which solves the problem that the existing satellite carrying battery test data is incomplete and intuitive, the sampling efficiency is low, the structure of the carrying equipment is complicated, and it cannot be used universally. The problem is that the device has the function of independent and simultaneous acquisition of multi-channel sub-battery data, which can collect current and voltage on the complete I-V curve, battery temperature, illumination angle, and test time in one cycle. Storage, processing and transmission, intuitively evaluate the performance of on-orbit solar cells, and ensure its sampling accuracy, short sampling time and high efficiency. Versatility
