  • Publication number: 20230335801
    Abstract: Embodiments of the present application provide an apparatus and a method for manufacturing an electrode assembly. The apparatus includes a driving portion, used for driving pole pieces to fall them from the driving portion; and a first support portion, arranged below the driving portion, and used for receiving the falling pole pieces, so that the pole pieces are stacked on the first support portion. The distance between an initial position of the upper surface of the first support portion and the driving portion being in a range of W to 2W. The initial position is the position of the upper surface of the first support portion when receiving the first pole piece of the electrode assembly, and W is the length of each pole piece. The apparatus can effectively stack the pole pieces to obtain an electrode assembly, and has high stacking efficiency.

  • Publication number: 20230100014
    Abstract: Techniques relating to monitoring map consistency are described. In an example, a monitoring component associated with a vehicle can receive sensor data associated with an environment in which the vehicle is positioned. The monitoring component can generate, based at least in part on the sensor data, an estimated map of the environment, wherein the estimated map is encoded with policy information for driving within the environment. The monitoring component can then compare first information associated with a stored map of the environment with second information associated with the estimated map to determine whether the estimated map and the stored map are consistent. Component(s) associated with the vehicle can then control the object based at least in part on results of the comparing.
