Abstract

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.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a high-voltage control method and system for electric vehicles and the electric vehicle. Background technique [0002] Electric vehicles have broad prospects for development because of their advantages such as energy saving and environmental protection. However, due to the limited electric energy stored in the power battery, the cruising range of the electric vehicle is short, and the single charge time of the power battery is long, which will undoubtedly limit the promotion and use of the electric vehicle. Therefore, people have correspondingly researched out battery quick-change technology to replace the power battery of electric vehicle rapidly at present. [0003] When the power battery is quickly changed through the battery quick change technology, it is difficult for the user to accurately judge whether the power battery has been quickly changed and installed in ...
