The invention discloses a high-voltage control method and system of an electric vehicle and the electric vehicle. The method comprises the following steps: detecting a quick-change signal of a power battery quick-change mechanism; detecting a locking signal of a power battery locking mechanism; judging whether a power battery is in a quick-change state or not, and judging whether the power battery is mounted in place or not according to the locking signal; and when the electric vehicle is not powered on with a high voltage, prohibiting the power battery from being powered on with a high voltage if the power battery is in a quick-change state, while allowing the power battery to be powered on with a high voltage if the power battery is not in a quick-change state and is mounted in place. Through the high-voltage control method and system of the electric vehicle according to the embodiment of the invention, the high-voltage safety in a quick-change process of the power battery can be guaranteed.
