The high voltage cutoff circuit comprises a high voltage loop and a high voltage cutoff control circuit, wherein the high voltage loop comprises high voltage components, a first relay and a second relay; both the first relay and the second relay are connected with each high voltage component; the first relay comprises a first contact; the second relay comprises a second contact; the high voltage cutoff control circuit comprises a battery management system, a whole automobile controller and a third relay; the battery management system is connected with the first relay and the second relay; the whole automobile controller is connected with the third relay; one end of the third relay is connected with a power supply of which the voltage is lower than 36 V; the first relay and the second relay are connected with the power supply through the third relay. The invention further provides the pure electric automobile with the high voltage cutoff circuit, and a high voltage cutoff control method based on the high voltage cutoff circuit.
Description
technical field [0001] The invention relates to the field of high-voltage control, in particular to a high-voltage cut-off circuit. In addition, the present invention also relates to a control method for the above-mentioned high-voltage cut-off circuit and a pure electric vehicle including the above-mentioned high-voltage cut-off circuit. Background technique [0002] With the development of the economy, energy and environmental protection issues have become increasingly prominent. All countries in the world have turned their attention to pure electric vehicles that are environmentally friendly and energy-saving. An important feature of pure electric vehicles is that they are equipped with high-voltage circuits that ensure sufficient power performance. [0003] The normal working voltage of the high-voltage circuit is as high as several hundred volts, which is far higher than the safe voltage of the human body at 36 volts. Therefore, in order to protect personal safety, it i...
