Abstract

The invention discloses an automobile power supply system and an electric vehicle, and relates to the technical field of automobiles. The main purpose of the automobile power supply system and the electric vehicle is used for reducing the size and the mass of an electricity power supply of the electric vehicle in the case of not affecting normal use of the electric vehicle. According to the technical scheme, the automobile power supply system comprises an electricity power supply and a power supply, the output end of the electricity power supply is connected to a plurality of constant electricdevices, the output end of the power supply is connected with the multiple constant electric devices through first control switches, and the output voltage of the power supply is greater than the output voltage of the electricity power supply; the multiple constant electric devices comprise controllers which are connected to the first control switches and used for receiving control signals and controlling closing or switching-off of the first control switches according to the control signals; when the first control switches are switched off, the electricity power supply supplies electricity to the multiple constant electric devices; and when second control switches are closed, the power supply supplies electricity to the multiple constant electric devices, and the electricity power supplystops supplying electricity to the multiple constant electric devices. The automobile power supply system is mainly used for supplying electricity to the electric vehicle.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a vehicle power supply system and the electric vehicle. Background technique [0002] The power supply system of an electric vehicle includes a high-voltage power supply and a low-voltage power supply. Among them, the high-voltage power supply is used to provide electric energy for the power of the vehicle, for example: for powering the motor; and other electrical components to provide electrical energy. [0003] With the rapid development of electric vehicles, the structure of electric vehicles is becoming more and more complex. Among them, due to the low-voltage power supply connected to more electrical components, this leads to its larger size and weight, which takes up more space in electric vehicles. space. Contents of the invention [0004] In view of this, an embodiment of the present invention provides an automobile power supply system and an electric vehicl...
