The DC-DC converter is provided between a first conductive path (e.g., first positive-electrode side conductive line), which is an electrical path between the first relay and a first capacitor in a first branch path, and a low-voltage battery, and steps down a voltage inputted from the first conductive path (e.g., first positive-electrode side conductive line) and outputs the voltage to the low-voltage battery The DC-DC converter is provided between a second conductive path (e.g., second positive-electrode side conductive line), which is an electrical path between the second relay and a second capacitor in a second branch path, and the low-voltage battery. and supplies electric power to the second capacitor by performing voltage boosting operation of boosting the voltage inputted from the low-voltage battery",
