  • Publication number: 20240100973
    Abstract: A vehicle includes: a battery; an electricity supply unit configured to be capable of supplying electric power from the battery to an external load; a charge port unit including a charge inlet that a charge connector is attached to and detached from, the charge connector being used for charging the battery with an external electricity source; and a control unit configured to control operation of a movable portion that is included in the charge port unit. When an external electricity supply process of supplying electric power from the electricity supply unit to the external load is executed, the control unit controls the movable portion of the charge port unit, to physically prohibit the charge connector from being connected to the charge inlet.

  • Patent number: 8794220
    Abstract: The invention provides a blow-by gas recirculating apparatus for a crankcase with enhanced ventilation efficiency. A fresh air introducing chamber is remote from a head cover. An upstream intake passage of a throttle valve is communicated with the fresh air introducing chamber, and the fresh air introducing chamber is communicated with a crankcase through a crankcase communication throttle hole which is opened in the crankcase. Fresh air in the upstream intake passage of the throttle valve is introduced into the crankcase sequentially through a fresh air introducing passage, the fresh air introducing chamber, and the throttle hole, without being short-circuited to a PCV valve. In a reverse flow from the crankcase to the upstream intake passage of the throttle valve, a gas in the crankcase reversely flows into the upstream intake passage sequentially through the throttle hole, the fresh air introducing chamber, and the fresh air introducing passage.
