Electric car and control system for high voltage power supply of electric car

Abstract

The invention discloses an electric car and a control system for a high voltage power supply of the electric car. The system comprises the high voltage power supply, multiple monitors, multiple position sensors and a power supply controller; the high voltage power supply is used for supplying power to multiple high voltage parts; each monitor is connected with the corresponding high voltage part and used for monitoring the connecting state of the high voltage part and a high voltage power line; each position sensor and a protective cover of the corresponding high voltage part are correspondingly arranged, and each position sensor is used for detecting the opening-closing state of the protective cover of the corresponding high voltage part; the power supply controller is used for starting the power supply function of the high voltage power supply when all the high voltage parts are connected with the high voltage power line and the protective covers of all the high voltage parts are closed. According to the electric car and the control system for the high voltage power supply of the electric car, the technical problem that in a related technique, the electric car safety is poor due to a high voltage system fault is solved.

Description

technical field

[0001] The invention relates to the field of electric vehicles, in particular to an electric vehicle and a control system for a high-voltage power supply of the electric vehicle. Background technique

[0002] Compared with traditional cars, one of the characteristics of electric vehicles is that the car is equipped with a high-voltage system to ensure sufficient power performance. ) and other high-voltage components, the hidden danger of high-voltage electrical damage is completely different from that of traditional cars. Its voltage as high as 300 volts and current that may reach tens or even hundreds of amperes test the use of high-voltage electrical appliances on the vehicle at any time. Safety, therefore, when there is a problem in the high-voltage system, high-voltage electrical appliances are easily affected by high-voltage and high-current, which directly affects the safe operation of electric vehicles.

[0003] For the technical problem of poor safet...
