A method for controlling a high-voltage system circuit of an electric vehicle comprises: judging whether the circuit is in a closed-circuit state after receiving an instruction of opening the circuit; judging whether the positive contactor is in an on-state and whether an instruction of turning on the positive contactor is valid if the circuit is in a closed-circuit state; sending an instruction of turning off the positive contactor if the positive contactor is in an on-state and the instruction of turning on the positive contactor is valid; sending an instruction of turning off the negative contactor; judging whether the pre-charging contactor is in an on-state and whether an instruction of turning on the pre-charging contactor is valid; sending an instruction of turning off the pre-charging contactor if the pre-charging contactor is in an on-state and the instruction of turning on the pre-charging contactor is valid.
