Satellite batteries must offer function and evolution

摘要

Television broadcasting, cell phones, GPS navigation, military surveillance, NASA science experiments - each of these is possible because of satellites. Batteries are a critical part of a satellite's ability to operate in space. Here's why we need batteries in satellites and what aspects of batteries are important in ensuring mission success. When a satellite is in orbit around the earth, the sun's light allows the solar panels located on either side of the satellite to generate power from their photovoltaic solar cells. However, satellites must depend on a second power source because the earth's daily rotation blocks the satellite from the sun either on a daily basis or during certain times of the year, depending on the satellite.
