The invention provides a battery pack SOC evaluation method and system. The method comprises the steps of: obtaining a maximum deviation value of battery module SOC values and a battery module SOC average value after obtaining the battery module SOC average value; and using the battery module SOC average value as a battery pack SOC value for output if the maximum deviation value is within an allowable deviation range. If the maximum deviation value is out of the allowable deviation range, the balance condition of the battery module SOC values is relatively poor, and further judgment whether a maximum battery module SOC value or a minimum battery module SOC value deviates most from the battery module SOC average value is needed. Different battery pack SOC algorithms are respectively provided for the two cases, so that the obtained result fits the practical condition of battery modules much better. According to the scheme of the embodiment, the battery pack SOC value is effectively enabled to be smoother, the real capacity of a battery pack is reflected more really, and the overcharging and over-discharging problems of the battery modules are relieved.

The invention provides a mouse DPI self-adaptive adjustment method and its application. Firstly, the user category is identified, and then the DPI value adapted to the user category is selected and set as the initial DPI value of the mouse. The mouse DPI value can be preliminarily selected according to the user category, the selection efficiency is high, and the amount of calculation can be significantly reduced. For different types of user categories, it is possible to have a relatively suitable mouse DPI value for primary selection. After the initial selection, the mouse DPI value is adjusted for the first time, and more than one subsequent adjustment is completed to complete the adjustment of the mouse DPI value, which can further make the mouse DPI value more suitable for the corresponding user category, and adopt optimal iteration and other algorithms in the prior art Selecting the DPI value can significantly reduce the amount of calculation, reduce the workload of the host, prevent the host from crashing or occupying a large amount of computing resources, and the adjustment time is shorter.
