  • Publication number: 20250145030
    Abstract: A vehicle includes a vehicle battery, a motor generator, a circuit, and a controller. The motor generator receives and outputs electric power from and to the vehicle battery and an external battery. The circuit couples the vehicle battery and the external battery to the motor generator. The controller controls the vehicle battery and the external battery, based on a first mode or a second mode. In the first mode, electric power is transferred between the motor generator and the vehicle battery and between the vehicle battery and the external battery, and not transferred between the motor generator and the external battery. In the second mode, electric power is transferred between the motor generator and the vehicle battery and between the motor generator and the external battery. The controller shifts to the first mode when a load applied to the circuit exceeds a predetermined load in the second mode.

  • Patent number: 11987289
    Abstract: A suspension structure for a power unit is configured to suspend a power unit including a motor, a transaxle, and a power control unit. In the suspension structure for a power unit, the transaxle is arranged in a substantially center portion in a vehicle width direction, the motor is arranged at a position on an upper side with respect to the transaxle, and on one side in the vehicle width direction, and the power control unit is arranged at a position on the upper side with respect to the transaxle, and on an opposite side of the motor. In the suspension structure for a power unit, the motor and the power control unit are suspended on a principal axis of inertia substantially parallel with an axis in the vehicle width direction.
