1. A fluid filling system for a vehicle, the system comprising:
a first receptacle;
a second receptacle;
a fluid distributing apparatus connected to the first receptacle and the second receptacle, the fluid distributing apparatus being configured to adjust a flow rate of a first fluid discharged from the first receptacle and a flow rate of a second fluid discharged from the second receptacle; and
a fluid introducing part connected to the fluid distributing apparatus and configured to receive the first fluid and the second fluid discharged from the fluid distributing apparatus,
wherein the fluid distributing apparatus comprises:
a first introduction passage connected to the first receptacle and through which the first fluid is introduced along a first direction;
a second introduction passage connected to the second receptacle and through which the second fluid is introduced along a second direction;
a discharge passage through which the first fluid introduced through the first introduction passage and the second fluid introduced through the second introduction passage are discharged; and
a flow rate adjusting part disposed between each of the first introduction passage and the second introduction passage and the discharge passage, the flow rate adjusting part being configured to adjust the flow rate of the first fluid or the second fluid, and
wherein the flow rate adjusting part comprises:
a first valve disposed in the first introduction passage and configured to adjust the flow rate of the first fluid;
a second valve disposed in the second introduction passage and configured to adjust the flow rate of the second fluid;
a connection passage connecting the first introduction passage and the second introduction passage;
a differential pressure measuring part disposed in the connection passage and configured to acquire a differential pressure of the first fluid and the second fluid in the connection passage; and
a controller electrically connected to the first valve and the second valve and configured to control opening and closing of the first valve and the second valve,
wherein the controller is configured to control opening degrees of the first valve and the second valve based on the differential pressure of the first fluid and the second fluid acquired by the differential pressure measuring part.
