  • Publication number: 20240097197
    Abstract: A non-aqueous rechargeable battery includes an electrode body in which a positive plate and a negative electrode plate are stacked in a stacking direction with a separator arranged in between. The positive electrode plate includes a positive electrode substrate, and a positive electrode mixture layer and an insulating layer arranged on each of two opposite surfaces of the positive electrode substrate. The positive electrode substrate includes a positive electrode uncoated portion. The electrode body includes a positive electrode current collector portion in which layers of the positive electrode uncoated portion are stacked in the stacking direction. A first insulating layer on a first surface of the positive electrode substrate, facing a center of the positive electrode current collector portion in the stacking direction, has a thickness that is greater than that of a second insulating layer on a second surface of the positive electrode substrate opposite to the first surface.

  • Patent number: 11919541
    Abstract: Automated drive system comprises a control device. The control device executes run control processing of the automated drive vehicle provided to a driverless transportation service. The run control processing includes carriage porch control processing. The carriage porch control processing is performed when a PUDO position of a user corresponds to a carriage porch of a facility including a zone for run and a zone for PUDO. In the carriage porch control processing, it is judged whether or not there is an empty space in the zone for PUDO. If it is judged that there is no empty space, it is judged whether or not a quick PUDO of the user in the carriage porch is expected. If it is judged that the quick PUDO is expected, a target PUDO position to perform a PUDO action of the automated drive vehicle is set to any position in the zone for run.
