PROBLEM TO BE SOLVED: To provide a vehicle power supply system, a vehicle power supply device and a loading device, capable of reducing a stop of a parallel run system by overload protection operation of the vehicle power supply device, and capable of improving conversion efficiency of the vehicle power supply device.SOLUTION: A vehicle power supply system 100 includes: loading devices 7; and at least two vehicle power supply devices 10 connected in parallel with each other, which supply power to the loading devices. Each vehicle power supply device obtains a total value of respective rated capacities and output capacities of the vehicle power supply devices during operation, and when the total output capacity is larger than the total rated capacity and when there is not the vehicle power supply device during suspension, performs output making a load restriction instruction effective during a period when this state is satisfied, and the loading device executes operation to reduce a load on the loading device during a period when the load restriction instruction is effective. |
