确定电池包的显示荷电状态SOC的方法与装置
By acquiring the actual SOC and displayed SOC of the battery pack, and combining the state of charge and discharge and the rate of SOC change, the SOC for the next display cycle is calculated using adaptive adjustment parameters. This solves the problem of inaccurate displayed SOC and achieves higher precision SOC display.

AI Technical Summary
Technical Problem
In the prior art, there is a discrepancy between the displayed state of charge (SOC) of the battery pack and the actual SOC, resulting in inaccurate SOC display and affecting user experience.
Method used
By acquiring the actual and displayed SOC of the battery pack at the current moment, and combining the state of charge/discharge and the rate of SOC change, the SOC for the next display cycle is calculated using adaptive adjustment parameters, and the displayed SOC is corrected to improve accuracy.
Benefits of technology
It achieves precise correction of the displayed SOC, ensuring that the SOC seen by users under different charging and discharging states is closer to the actual SOC, thus improving the user experience.

Abstract
本申请提供一种确定电池包的显示荷电状态SOC的方法与装置，涉及电池管理领域。在上述的方法中，获取当前时刻k对应的第m个采样周期的实际SOC和所述当前时刻k对应的第n个显示周期的显示SOC，所述当前时刻k为所述第n个显示周期结束前的时刻；根据所述当前时刻k所述电池包的充放电状态、所述第n个显示周期的显示SOC、所述第m个采样周期的实际SOC和所述第n个显示周期的显示SOC的变化速率，确定第n+1个显示周期的显示SOC的变化速率；根据所述第n+1个显示周期的显示SOC的变化速率以及所述第n个显示周期的显示SOC，确定第n+1个显示周期的显示SOC。如此，实现了对显示SOC的修正，使第n+1时刻显示的SOC更加精确。
