The invention discloses a double-air-source system of an electric vehicle and a method and system for controlling the double-air-source system of the electric vehicle. A first air compressor and a second air compressor in the double-air-source system are controlled by a control module. An air outlet of the first air compressor is connected with a brake loop of the electric vehicle through a first pipeline. An air outlet of the second air compressor is connected with the brake loop through a second pipeline. By the adoption of the double-air-source system, due to the fact that the first air compressor and the second air compressor are used as standby air sources for each other, the reliability of the air source system and the reliability of the brake loop are improved, and safe operation of the electric vehicle is guaranteed. When the second air compressor is used as the engine air compressor, due to the fact that the first air compressor can be used as an air source of the brake loop, the pure electric mode can be selected as the working mode of the whole vehicle when the first air compressor works and the second air compressor is on standby; in this way, air supply work of the double-air-source system cannot disturb normal switching between the work modes of the whole vehicle, and decoupling between air supply work and working mode switching of the whole vehicle is achieved.
Description
technical field [0001] The invention relates to the technical field of electric vehicle air supply control, in particular to an electric vehicle dual air source system, a control method and a control system thereof. Background technique [0002] In the prior art, the electric vehicle using the plug-in hybrid power system generally adopts a single air source for the whole vehicle, and there are two schemes for the single air source: scheme 1 uses an electric air compressor (referred to as an electric air compressor) As the only air source, the motor drives the air compressor to run; Scheme 2 uses the engine air compressor (referred to as the engine air compressor) as the only air source, and the engine drives the air compressor to run. [0003] The gas source system described in Scheme 1 has low reliability due to the large number of associated electrical components. The air source system described in Scheme 2 has high reliability, and it is composed of an engine air compres...
