摘要： A power supply of a vehicle includes a first switching element, a second switching element, a third switching element, a first battery, a reactor element, a second battery, a smoothing capacitor, and a controller. When the connection state of the first battery and the second battery is switched from the series connection state to the parallel connection state, the controller is configured to perform a transition control so that a voltage of the smoothing capacitor is decreased to the higher of a voltage of the first battery and a voltage of the second battery, and perform a switching control to turn on the first switching element after a diode of the first switching element is energized.

摘要： An all-solid-state battery manufacturing apparatus disclosed herein includes a transport apparatus, a press roller, and an adhesive provision apparatus. The transport apparatus transports an active material layer. The press roller has a foil attachment surface, which is a cylindrical surface to which the current collection foil is to be attached. The press roller rotates and moves the current collection foil attached to the foil attachment surface to the surface of the active material layer being transported by the transport apparatus and presses the current collection foil and the active material layer between the press roller and the transport apparatus. The adhesive provision apparatus is provided on a movement path of the current collection foil rotated and moved by the foil attachment surface of the press roller, and provides an adhesive to the current collection foil attached to the press roller.
