    Abstract: A control system and a control method of fuel cell stacks are provided. The control system includes a set of fuel cell stacks, a secondary battery, a monitoring device, and a control device. Each fuel cell stack has a power output that can be independently started up or shut down. The secondary battery is connected to power output terminals of the fuel cell stacks via a power transmission path.

  • Publication number: 20220350758
    Abstract: The invention relates to a method, a non-transitory computer-readable storage medium, and an apparatus for executing an embedded multi-media card (eMMC) command. The method is performed by a processing unit of a flash controller to include: receiving an eMMC command from a host side; and performing a first function associated with a host performance acceleration (HPA) mode according to content of reserved bits of the eMMC command. The HPA mode allows the host side to allocate space in a system memory as an HPA buffer. The HPA buffer stores logical-block-address to physical-block-address (L2P) mapping entries obtained from the flash controller, and each L2P mapping entry stores information indicating which physical address that user data of a corresponding logical address is physically stored in a flash device, thereby enabling the host side to issue an HPA read command carrying the physical address to the flash controller.
