  "textContent": "An electric power supply system (1) includes an alternating electric current power supply circuit (2) that converts direct current electric power of a first direct current sweep unit (10) including a battery string (Stl) into alternating electric current using a first inverter (51) and outputs it, and an alternating current sweep unit (3) that includes a U-phase battery string (St4), a V-phase battery string (St6), and a W-phase battery string (St8) that are Y-connected. Output densities of batteries (B) of the battery string (Stl) are higher than output densities of batteries (B) of the alternating current sweep unit (3). Alternating electric current is output from the alternating current sweep unit (3) and the alternating electric current power supply circuit (2), and after a predetermined period elapses, the alternating electric current output from the alternating electric current power supply circuit (2) is stopped.",
