The invention discloses a power isolation switch control circuit, a vehicle and a control method. The power supply isolation switch control circuit comprises a first power supply input end, a second power supply input end and a power supply branch between the first power supply input end and the second power supply input end. The power supply branch comprises a first isolation module and a second isolation module which are connected in series with the power supply branch; the power supply isolation switch control circuit further comprises an electric signal detection module and a control module. The electric signal detection module is used for detecting an electric signal corresponding to the current passing through the power supply branch; the control module is electrically connected with the electric signal detection module and is used for determining whether overcurrent exists in the power supply branch according to the electric signal detected by the electric signal detection module and controlling the first isolation module and the second isolation module to be disconnected in sequence according to the current direction when overcurrent exists, and the sequence of disconnection is related to the current direction. Circuit elements can be prevented from being damaged by sudden change of electric signals when the current of the power supply branch is cut off.
