description A current protection circuit for a high voltage system includes: a power supply module to supply power to a load through a high voltage bus and a low voltage bus; a detection module connected to the high voltage bus and used to detect a value of current flowing through the high voltage bus; a signal processing module electrically connected to the detection module and used to amplify the current flowing through the high voltage bus; and a control module electrically connected to the signal processing module, the power supply module, and the load, and used to disconnect the load from the power supply module or perform current limiting for the load when the value of the amplified current exceeds a preset threshold.
