Control system of electric vehicle

Abstract

The invention discloses a control system of an electric vehicle, and particularly relates to the technical field of control systems. The control system comprises an instrument panel, the input end of the instrument panel is electrically connected with a leakage protection circuit, the input end of the leakage protection circuit is electrically connected with a high-temperature protection circuit, and the input end of a high-temperature protector is electrically connected with a voltage output end; the input end of the voltage output end is electrically connected with a battery, and the input ends of the instrument panel, the electric leakage protection circuit, the high temperature protection circuit and the voltage output end are electrically connected with a master control circuit. By arranging the high-temperature protector, the over-temperature protection effect of the high-temperature protector is utilized, and after the electric vehicle is exposed outdoors, once the temperature of a power supply in the electric vehicle exceeds 90 to 100 DEG C, the high-temperature protector immediately cuts off the output end of the power supply. the battery cannot work properly, and the problem that the wear rate of the battery is too high when the battery works at a high temperature is solved.

Description

technical field [0001] The invention relates to the technical field of control systems, and more specifically, the invention relates to a control system of an electric vehicle. Background technique [0002] The electric vehicle controller is the core control device used to control the start, operation, advance and retreat, speed, stop and other electronic devices of the electric vehicle motor. It is like the brain of the electric vehicle and an important part of the electric vehicle. At present, electric vehicles mainly include electric bicycles, electric two-wheeled motorcycles, electric tricycles, electric three-wheeled motorcycles, electric four-wheeled vehicles, battery cars, etc. Electric vehicle controllers also have different performance and characteristics due to different models. . [0003] However, there are still some disadvantages in its actual use, such as: [0004] (1) When the existing device is in use, due to the lack of a leakage protector in the existing ...
