Monitoring system and monitoring method for electric vehicle and its high-voltage distribution box

Abstract

The invention discloses a monitoring system and a monitoring method for an electric vehicle and its high-voltage distribution box, wherein the monitoring system includes: a detection module for detecting the working environment signal of the high-voltage distribution box, wherein the working environment signal includes the high-voltage distribution box The temperature signal in the electric box, the working voltage signal and working current signal of each high-voltage device in the high-voltage distribution box, the smoke concentration signal in the high-voltage distribution box; the communication module; the main chip module, used for The high-voltage distribution box is monitored to generate monitoring information, and the monitoring information is sent to the battery management system through the communication module, so that the battery management system can adjust the control strategy of the electric vehicle according to the monitoring information. The system can monitor and control the high-voltage distribution box in real time, and send the monitoring information to the battery management system, so that when the high-voltage distribution box fails, it can quickly control the fault strategically, making the fault controllable and greatly Improve the safety of the vehicle.

Description

technical field [0001] The present invention relates to the technical field of automobiles, in particular to a monitoring system for a high-voltage distribution box of an electric vehicle, an electric vehicle, a method for monitoring a high-voltage distribution box of an electric vehicle, and a non-temporary computer-readable storage medium . Background technique [0002] Vehicles are the accelerator of economic development and the main means of transportation for people. With the further shortage of energy and the increasing pollution, driven by the general trend, new energy vehicles, such as electric vehicles, have gradually replaced traditional fuel vehicles and become the protagonists of transportation. [0003] The most important power system of electric vehicles is the power battery, such as figure 1 As shown, electric vehicles generally manage power batteries through BMS (Battery Management System, battery management system), and control the on-off of high-voltage s...

Problems solved by technology

[0004] However, in the above method, the BMS can only control the on-off of the high-voltage switchgear in the high-voltage distribution box according to the set control strategy and the given input, and cannot real-time control the high-voltage distribution box according to the specific conditions of the high-voltage distribution box. The high-voltage switchgear in the electric box is controlled. When the high-voltage distribution box has abnormal load operation, abnormal power supply of the vehicle system, and electrical aging, it cannot be processed in time, which may cause high-voltage safety accidents such as equipment burnout and even fire. Seriously affect the safety of the vehicle
