Intelligent voice prompt system of new energy automobile and control method of intelligent voice prompt system

Abstract

The invention discloses an intelligent voice prompt system of a new energy automobile and a control method of the intelligent voice prompt system, and relates to the technical field of electric automobile vehicle-mounted internet. The system is provided with an electric automobile double-circuit power supply system and can maintain, self-inspect and evaluate a battery. The system comprises the battery, a first switch, a second switch, a power management module, a low-voltage load, a first node, a second node, a third node, a key switch module, a vehicle control module and a third switch; one end of the first switch, one end of the second switch and the anode end of the battery are connected to the first node; the other end of the second switch, the other end of the third switch, the anode end of a power interface of the power management module and the anode end of a power interface of the low-voltage load are all connected to the second node; the cathode end of the battery, the cathode end of the power interface of the power management module, the cathode end of the power interface of the low-voltage load and the cathode end of a power interface of the vehicle control module are all connected to the third node.

Description

technical field [0001] The invention relates to the technical field of intelligent voice prompts for new energy vehicles, in particular to an intelligent voice prompt system for new energy vehicles and a control method thereof. Background technique [0002] At present, the voice prompt function of electric vehicles and new energy vehicles is relatively simple. After the key signal is turned off for most electric vehicles, the power management module, which is the core of the power supply system, has no power supply, and cannot power management after the key signal is turned off. If the module conducts a comprehensive evaluation of safety and reliability, it will not be able to make early warning information prompts and ensure the safety of the next operation. The existing electric vehicle adopts the plug-and-play charging method, which has a low degree of intelligence. Moreover, after the driver parks the existing electric vehicle, if the car is removed by someone, the driv...

AI Technical Summary

Problems solved by technology

[0003] The present invention aims to solve the above-mentioned shortcomings of the single voice prompt function of existing new energy vehicles, and provides a dual-circuit power supply system for electric vehicles, which can ensure that the power management module continues to have power within the set time after parking, and can maintain battery life. Carry out maintenance, self-inspection, and evaluation to ensure the safety of electric vehicles during the next operation, eliminate unsafe factors in advance, and keep the capacity difference between each battery within the preset capacity difference range. It is easy to know and easy to find the position of the removed car, the speed of the electric car on the road is also easy for the driver's relatives to know, and it is convenient for the driver's relatives to send reminder information to the driver.
