  "textContent": "A vehicle electric power system includes a main DC-DC converter and an auxiliary battery, a sub DC-DC converter, a first switch and a second switch that are provided in series between a main power supply system and a sub power supply system, and a controller. The main DC-DC converter and the auxiliary battery are connected to the first load connected to the main power supply system and are configured to supply electric power. The sub DC-DC converter is connected to a second load connected to a sub power supply system and is configured to supply electric power. When a failure occurs in the main DC-DC converter, the controller stops a load that is not required to operate upon the failure and controls the first switch and the second switch such that the electric power is supplied to the first load after the voltage of the sub DC-DC converter is normal.",
