Abstract: Provided are a battery pack and an electric vehicle. The battery pack includes a case, a cooling plate assembly and an energy storage unit. The cooling plate assembly and the energy storage unit are arranged inside the case, and the cooling plate assembly at least includes a first cooling plate. The first cooling plate is fixed on the case, and the first cooling plate divides the case, in a Z-direction, into a first accommodating space which is located above the first cooling plate, and a second accommodating space which is located below the first cooling plate. The energy storage unit at least includes a first energy storage unit which is arranged inside the first accommodating space and fixed on the first cooling plate, and a second energy storage unit which is arranged inside the second accommodating space.

Abstract: A method, an apparatus, and a system for enabling a processor to access shared data are provided to overcome low efficiency of a storage system. The method includes that the processor sends a storage block locking command to the storage system through a hardware thread, where the command instructs the storage system to lock a storage block; the processor judges whether a storage block locking completion message has been received from the storage system in a preset clock period; and, schedules the hardware thread to access shared data in the storage block if the storage block locking completion message has been received from the storage system in the preset clock period, or schedules the hardware thread to keep waiting for the storage block locking completion message from the storage system if no storage block locking completion message has been received from the storage system in the preset clock period.

Abstract: A concurrent instruction operation method and device are provided. The method includes: establishing a concurrent queue, and setting a queue base address and a queue maximum length of the concurrent queue; generating concurrent operation instructions according to a length of data that needs to be written or read as well as the queue base address and queue maximum length of the concurrent queue; and executing the concurrent operation instructions in the concurrent queue, and completing a data operation to the concurrent queue.
