  • Patent number: 12212201
    Abstract: A cooling system is provided. Coil ends protrude outward from a first end of a stator core in a direction along a central axis. An imaginary straight line is orthogonal to both of a central axis of a core body and an axis extending in an up-down direction. Half the coil ends above the imaginary straight line are in a first portion. Each of the segment coils in the first portion includes an outer peripheral surface that faces in a direction opposite from the central axis. The outer peripheral surface of each of the segment coils includes a twisted surface. The direction in which the twisted surface faces becomes closer to the direction facing the stator core as the twisted surface extends toward the first end of the stator core.

  • Patent number: 11319856
    Abstract: A vehicle includes a battery and a CO2 recovery device using electric power of the battery to recover CO2 contained in inflowing gas. A control device mounted in the vehicle controls the CO2 recovery device. The control device permits operation of the CO2 recovery device in the case where a high efficiency recovery condition, at which it is predicted that the efficiency of recovery of CO2, showing a ratio of the amount of recovery of CO2 in the CO2 recovery device with respect to the electric power consumed by the battery, will become equal to or greater than a preset predetermined efficiency, is satisfied, and prohibits operation of the CO2 recovery device in the case where the high efficiency recovery condition is not satisfied.
