Electric power supply systems and power supply equipment for electric vehicle

A power supply system for electric vehicles, the power supply system comprising:

• a power supply;
• a first power line;
• and
• a second power line;
• wherein an output of a high voltage side from the power supply is fed to the high voltage side of each of the first power line and the second power line,
• an output of a low voltage side from the power supply is fed to the low voltage side of each of the first power line and the second power line,
• the first power line and the second power line are connected at their far ends,
• the power supply system supplies electric power to the electric vehicles by means of said first power line or said second power line,
• the first power line and the second power line have bypass lines that interconnect from the power supply to a connection at the far end,
• the second power line is disposed on an inclined region between the power supply and the connection, and
• a first electric vehicle traveling in the inclined region on a down line has a restraining brake or a regenerative brake that generates power when restraining a speed of the first electric vehicle, and the generated power is supplied through the bypass lines to a second electric vehicle traveling in the inclined region on an up line.
