Description

technical field [0001] This application relates to the technical field of rail transit and energy routers, in particular to an energy router, a vehicle control method, and a storage medium. Background technique [0002] As a world-recognized means of transportation with low energy consumption, low pollution, fast, convenient and safe, urban rail transit has become one of the fields with the most intense international competition and the highest level of innovation drive in the field of domestic cutting-edge manufacturing technology. With the rapid development of urban rail transit, energy saving and intelligentization are important development trends of rail transit today, and the issue of energy saving and emission reduction has become increasingly prominent. [0003] During the operation of rail transit, frequent starting, acceleration, braking and other processes will lead to particularly obvious fluctuations in the traction power of rail transit, and the power demand dur...
