Abstract: Disclosed are a pallet configured to bear a battery cell. The pallet includes an external fixing rack and a plurality of supporting beams. A mounting space is formed inside the external fixing rack. The plurality of supporting beams are disposed in the mounting space. The plurality of supporting beams are arranged along a first direction. The plurality of supporting beams are connected to the external fixing rack separately. At least two of the supporting beams are spaced apart. The plurality of supporting beams are configured to bear the battery cell.

Abstract: The present disclosure provides a data transmission method and system. The method includes: requesting to access a data file from an intermediate node; receiving response data packets of the data file from the intermediate node, where the response data packets include a data file signature code uniquely identifying the data file; looking up the signature code in a signature code database; when the signature code is present in the signature code database, notifying the intermediate node to stop the transmission of the data file, and creating a cache pointer record to point to a cached data file corresponding to the signature code; and sending the cached data file to a user agent.

Abstract: A method for managing network service includes: when a target server is in a self-controlled “ON” state, detecting, by the target server, an actual on-and-off state of a target network service every preset period of time, and acquiring, by the target server, a standard on-and-off state of the target network service from a control center; if the target network service needs to be turned off based on the standard and actual on-and-off states, sending, by the target server, a service turn-off request of the target network service to the control center; if it is allowed to turn off the target network service, sending, by the control center, a service turn-off notification to the target server, and updating the standard on-and-off state of the target network service of the target server to an “off” state; and after receiving the service turn-off notification, turning off, by the target server, the target network service.
