Urban rail transit is an important component of modern cities, and efficient energy storage technology helps improve its operational efficiency and environmental compatibility. For example, during braking, the vehicle can convert kinetic energy into electrical energy, store it in supercapacitors or batteries, and then reuse this energy during acceleration, thereby reducing energy consumption and environmental pollution.
This technology, known as energy feedback, can not only help urban rail transit systems save energy, but also reduce dependence on traditional power grids, improve system independence and reliability. With the acceleration of urbanization and the increasing demand for sustainable transportation solutions, energy storage technology in urban rail transit will become an important trend for future development.
