Abstract

The invention provides a power supply system of a vehicle. A control device distributes electric power from a battery to an electric power feed terminal when the remaining level of a battery is equal to or higher than a predetermined value with an ignition off. Therefore, an electronic component can be charged after being connected to the electric power feed terminal, even with the ignition off. When the remaining level of the battery is lower than the predetermined value, the distribution of electric power from the battery to the electric power feed terminal is shut off, so the electric component can be stopped from being charged, even after being connected to the electric power feed terminal. In consequence, even when the electronic component can be charged after being connected to the electric power feed terminal with the ignition off, a battery remaining level that is needed when a vehicle runs next time can be ensured.

Description

technical field [0001] The present invention relates to an electric power supply system for a vehicle when the ignition is off. Background technique [0002] Japanese Unexamined Patent Application Publication No. 2019-164716 (JP2019-164716A) discloses a method of connecting electronic components such as a personal computer or a smartphone to a power feeding terminal (Universal Serial Bus, USB) terminal) and charge the electronic components. [0003] However, the techniques disclosed in the above publications have the following problems. When the ignition is turned off and when the ignition is turned on, the remaining capacity of the battery becomes low in order to continuously charge the electronic components. Therefore, when the ignition is turned on again to drive the vehicle, the remaining battery level required for the vehicle to reach the destination (the remaining battery level required for the next time the vehicle is driven) may not be ensured. Contents of the in...
