  • Publication number: 20240178469
    Abstract: A method and an apparatus for monitoring energy storage cell abnormality, an electronic device, and a medium are provided. The method includes: obtaining valid state data of a first cell in a battery module at a preset time; obtaining a discrete statistical state characteristic of the first cell based on the valid state data of the first cell; calculating distances between the discrete statistical state characteristic of the first cell and discrete statistical state characteristics of each remaining cells in the battery module separately, averaging the set of distances, to obtain a distance characteristic associated with the first cell; and determining whether the first cell is abnormal based on the distance characteristic of the first cell. Consistency monitoring of each cell in the battery module is implemented based on the state data of each cell, so that an early warning indicative of a possible fault can be issued.

  • Publication number: 20240113519
    Abstract: A method and a device for forecasting an electric load, an electronic device, and a computer-readable storage medium are provided. The method includes: acquiring historical load data prior to a forecast date; generating a load sequence based on the historical load data; performing variational mode decomposition on the load sequence, to obtain multiple intrinsic mode components and a residual that are corresponding to the load sequence; and inputting the multiple intrinsic mode components and the residual into respective forecasting models, and determining a load value on the forecast date based on forecasting results of all the forecasting models. With the method and the device, the electronic device, and the computer-readable storage medium, the load sequence is decomposed based on the variational mode decomposition, so that more dimensional feature information in the load sequence can be mined. Moreover, the residual is also used as valid data.

  • Patent number: 9652223
    Abstract: The present disclosure provides methods and apparatus for executing integrated application programs. An implementation class of an instantiation application program is executed in a first process, to obtain a context of a first application program including a first identifier. Or an implementation class of an instantiation application program is executed in a second process, to obtain a context of a second application program including a second identifier. It is determined whether an identifier corresponding to a current process is the first identifier or the second identifier. If the identifier corresponding to the current process is the first identifier, the first application program is executed when an initialization starts. Or, if the identifier corresponding to the current process is the second identifier, the second application program is executed when an initialization starts.
