Abstract
Systems and methods for discharging a high-voltage bus coupled to a discharge circuit are provided. A method comprises obtaining a first voltage level of the high-voltage bus. The method further comprises determining a first discharge time based on the first voltage level and activating the discharge circuit. The method further comprises obtaining a second voltage level of the high-voltage bus after the first discharge time, comparing the first voltage level and the second voltage level, and deactivating the discharge circuit if a difference between the first voltage level and the second voltage level is less than a threshold value.
