The invention discloses a power supply system, method and device for an electric intelligent automobile, and a storage medium, which belong to the technical field of intelligent automobiles. The system comprises a first power supply power source, a first power monitoring circuit, an automatic driving system, a direct current voltage converter, a power battery, a second power monitoring circuit, ahigh voltage switch, and a high voltage switch control circuit; The second power monitoring circuit and the high voltage switch control circuit are circuits that meet safety level requirements of an automobile safety integrity level ASIL D; the first power monitoring circuit is a circuit that satisfies the safety level requirements of the ASIL D; and the power battery, the direct current voltage converter and the high voltage switch are a second power supply power source of the electric intelligent automobile. In the power supply system, the first power supply power source and the second powersupply power source are mutually standby power sources, and the safety level of the power supply system reaches the ASIL D, thereby improving power supply reliability and driving safety of the electric intelligent automobile.
Description
technical field [0001] The invention relates to the technical field of smart cars, in particular to a power supply system, method, device and storage medium for electric smart cars. Background technique [0002] With the development of technology, the degree of intelligence of electric smart vehicles is getting higher and higher. While electric smart cars bring convenience and driving experience to people, the problem of car safety is becoming more and more prominent. For example, when the power consumption system in an electric smart car that supports the intelligence of the electric smart car is working, it needs the power supply in the electric smart car to supply power. System, brain control decision-making system, braking system, steering system and other systems will all be unable to work, resulting in the inability of electric smart cars to drive, and more seriously, dangerous incidents will occur. Therefore, need badly a kind of power supply system of electric smar...
