[0029] Examples:
[0030] In this embodiment, a method for detecting the driving range of an electric vehicle power battery, such as figure 1 As shown, it includes the following steps:
[0031] Step 1: Execute the system to detect the power battery, and obtain the current remaining power SOC, temperature T, minimum discharge power P, and minimum remaining power value SOC of the power battery L , The maximum remaining power value of the power battery SOC H ; The minimum remaining power value of the power battery SOC L , The highest remaining power value SOC H Pre-defined by the execution system, the lowest remaining power value SOC L Is 0%, and the maximum remaining power value SOC H Is 100%.
[0032] Step 2: Calculate the current remaining power SOC and the minimum remaining power value SOC of the power battery according to the acquired parameters L , The highest remaining power value SOC H Discharge energy in state E c , E L , E H ; The calculation steps of the discharge energy inclu...
