Intelligent circuit management system of electric automobile and management control method of intelligent circuit management system

Abstract

The invention relates to an intelligent circuit management system of an electric automobile and a management method of the intelligent circuit management system. The intelligent circuit management system comprises an intelligent circuit management module, a control execution module, a circuit monitoring wire harness, a wire connection temperature sensor and an information collecting and processing module, wherein the control execution module, the circuit monitoring wire harness, the wire connection temperature sensor and the information collecting and processing module are directly or indirectly connected with the intelligent circuit management module; the intelligent circuit management module receives and processes circuit data from the circuit monitoring wire harness, the wire connection temperature sensor and the information collecting and processing module, obtains control information, then transmits the control execution module to convert the control information into a specific control instruction and controls an electric appliance for a load connected with the intelligent circuit management system. By adopting the intelligent circuit management system of the electric automobile and the management method of the intelligent circuit management system, standardized components are adopted by hardware, so that the complexity level of the intelligent circuit management system is greatly lowered and a great role is provided for intelligent management of the electric automobile.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to the field of circuit control of electric vehicles, and specifically refers to an electric vehicle intelligent circuit management system and a management and control method thereof. Background technique [0002] The electric vehicle circuit can be divided into low-voltage circuit and high-voltage circuit according to voltage, and can be divided into power circuit and load circuit according to whether it contains power supply. Electric vehicles can be divided into 5 parts: low-voltage power supply system (responsible for low-voltage power supply, guarantee, fault handling, emergency treatment, etc.), high-voltage power supply system (responsible for high-voltage power supply, guarantee, fault handling, emergency treatment, vehicle charging, etc.) , load system, vehicle control system (responsible for driving operation information processing, vehicle control strategy, information in...

AI Technical Summary

Problems solved by technology

The main disadvantages of this approach are: there are many control components, the control program is complicated, the circuit harness is complicated, and it takes up a lot of space.

[0006] Judging from the current technological development, the current development of vehicle electrical components is relatively fast and good in terms of structural integration and wiring harness connection, which meets the convenience of assembly and use of electric vehicles, but does not do enough in terms of safety and management of integrated circuit systems. Specialization, some typical manifestations are: the battery management system performs simple control on the high-voltage power supply circuit, but does not extend to the control of the high-voltage circuit of the load, which affects the use and high-voltage safety; the traditional vehicle controller only controls the circuit components It can perform simple control, but the various control components and control requirements make the vehicle control software complex, and it takes a lot of work to process the control logic of the circuit components, which greatly affects the function and refinement of the vehicle control strategy; circuit information is crucial, It is related to vehicle safety, management and control. At this stage, the main detection and maintenance need to be handled manually, which is inconvenient; although some integrated components have done some work on circuit detection and control in order to strengthen product functions, but in the comprehensive load circuit Comprehensive system management is still lacking
