Abstract: The energy storage system includes battery cells, a subrack, a backplane, and a battery management system BMS. The subrack reserves a plurality of battery cell slots, the battery cells are connected to the backplane through the battery cell slots. The backplane is installed in the subrack, a first power terminal is reserved at a position corresponding to the battery cell slot on the backplane, and a plug-in power terminal is formed by a second power terminal of the battery cell together with the first power terminal. A power circuit, a sampling circuit, and an equalizer circuit are integrated into the backplane, and the power circuit, the sampling circuit, and the equalizer circuit are connected after the second power terminal is plugged and docked with the first power terminal. The BMS is connected to the backplane for managing the energy storage system.

Abstract: A battery system is provided, including a processing module and a plurality of battery modules. Each of the plurality of battery modules includes a battery management system and an electrochemical cell pack controlled by the battery management system. The processing module is configured to control the electrochemical cell pack to alternately perform a discharging or charging operation. A sum of power of battery modules other than a first battery module in the plurality of battery modules is greater than power required by a target power-supplied object, and the first battery module is any one of the plurality of battery modules. A battery management system is configured to record a target time. The processing module or the battery management system is configured to determine a state of health of the electrochemical cell pack in the first battery module based on the target time.

Abstract: A semiconductor component and an electronic device are structured to reduce a gate-drain parasitic capacitance of the semiconductor component. The semiconductor component includes: a substrate; a channel layer and a barrier layer that are sequentially stacked on the substrate; a source and a drain that are disposed on the barrier layer; a first gate and a second gate that are disposed on the barrier layer. The first gate and the second gate are located between the source and the drain, and the second gate is disposed between the first gate and the drain. A first gate field plate is at least partially disposed on a side that is of the first gate and that is close to the drain; and a first source field plate. The first source field plate covers the first gate field plate.
