  • Patent number: 11555713
    Abstract: An input of a destination and an input of a desired number of power supply facilities via which a vehicle travels on a route from a present location to the destination until an amount of power available becomes 0 are received. The number of facilities are selected and the route to the destination via the number of facilities is specified, the number of facilities being selected such that an amount of power with which the vehicle is able to travel a distance obtained by adding a margin distance to a distance to a farthest facility is less than the amount of power available when the route is specified. An alert is reported when the amount of power available is less than an amount of power required to travel the distance obtained by adding the margin distance to the distance to the farthest facility of the selected facilities.

  • Publication number: 20130342168
    Abstract: An electrical storage device includes a plurality of power-generating elements, a case, and a valve. The power-generating elements perform charge and discharge and are connected electrically in series. A plurality of housing sections each accommodate one of the plurality of power-generating elements and are disposed along a predetermined direction. A communication path switches from a closed state to an opened state depending on the internal pressure of the housing section. When the communication path is in the opened state, gas can be moved between two of the housing sections adjacent to each other in the predetermined direction. The valve is provided for a particular housing section and releases gas produced within the case to the outside of the case. The empty space other than the power-generating element is present in each of the housing sections, and the empty space in the particular housing section is the largest.
