Abstract: The present application discloses a battery pack and an electric device. An end face of a pole of a single battery of the battery pack in a preset direction is connected to a bus-bar or a connector. In the present application, a position where the bus-bar or the connector is connected on the end face of the pole is spaced apart from an outer edge of the end face, that is, a welding position on the end face of the pole is spaced apart from the outer edge of the end face. In this way, the welding position on the end face of the pole can be kept as far away as possible from a sealing member, thereby reducing the risk of the melting of sealing member during welding and consequently reducing the risk of sealing failure of the sealing member.

Abstract: The present disclosure provides a file delivery method. The file delivery method includes receiving a task request for a file delivery task sent by a target node to request a file; determining according to the task request whether there are completed nodes, the completed nodes being other target nodes that have completed a file delivery task delivering the file; designating, if there are completed nodes, a node from the completed nodes as a source station corresponding to the task request; designating, if there are no completed nodes, a source server as the source station corresponding to the task request; and delivering the file to the target node through the designated source station.

Abstract: A method of using a mobile terminal to implement cloud searching is provided. The method includes receiving, by the mobile terminal, searching conditions inputted by a user; executing, by the mobile terminal, local searching; and detecting whether networking is executed If networking is executed, the method includes detecting, by the mobile terminal, whether the local stores user account information; and connecting to a cloud server when the local of the mobile terminal stores the user account information. If networking is not executed, the method includes returning local searching results. The method further includes transmitting, by the mobile terminal, the searching conditions to the cloud server; and executing, by the cloud server, cloud searching according to the searching conditions; and returning searching results to the mobile terminal.
