Abstract: Provided is a shopping cart capable of simplifying equipment of a storage area of the shopping cart. A shopping cart allowed to be nested in a front-rear direction, including: a cart body; a battery configured to supply power to an electronic device attached to the cart body and displayed commodity information read by a reading device; a power receiving portion provided on a front side of the cart body and configured to be electrically connectable to an external power supply; and a power transmitting portion provided on a rear surface side of the power receiving portion and configured to supply power to a power receiving portion of another shopping cart nested in the shopping cart. Each of the power receiving portion and the power transmitting portion is provided with a magnet configured for holding a relative position.

Abstract: A data generation apparatus includes a first generation unit configured to, based on altitude data including altitude values of a plurality of points and road map data indicating roads with a plurality of nodes and a plurality of links, generate road altitude data in which each of the plurality of nodes is given an altitude value of a corresponding one of the plurality of points, and a second generation unit configured to, based on the road altitude data, calculate gradient information indicating a gradient between any two nodes among the plurality of nodes and generate road gradient data in which the plurality of nodes or the plurality of links are given the gradient information.

Abstract: A control unit executes: a route information display process of displaying route information of a route from a starting point to the destination, the route searched for based on a current level of a battery, and including a charging facility as a relay point; a first guidance information display process of displaying guidance information for guiding traveling of the vehicle from the starting point to the relay point, when the vehicle starts traveling at the starting point; a notification input screen display process of displaying an input screen that receives an input for notifying resumption of traveling of the vehicle, when the vehicle resumes traveling after having arrived at the relay point; and a second guidance information display process of displaying guidance information for guiding traveling of the vehicle from the relay point to the destination, when the input for notification has been received on the input screen.

Abstract: A charging assistance system includes a processor configured to execute a generation process of generating charging plan data for a vehicle on the basis of: predicted power consumption of the vehicle calculated on the basis of a future traveling schedule of the vehicle; and a charging condition at each predicted stop place based on the traveling schedule.
