Intelligent protection switch of electric vehicle

Abstract

The invention provides an intelligent protection switch of an electric vehicle. Connection and disconnection of a main power supply circuit of the electric vehicle are controlled by controlling on-offof a contact switch; and a detection module and a control module are connected in the main power supply circuit of the electric vehicle, so that the state of each functional unit of the electric vehicle can be better detected, the control module controls on-off of the contact switch according to the state of each functional unit of the electric vehicle, the running state of the electric vehicle can be better detected, and the spontaneous combustion phenomenon of the electric vehicle is avoided.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to an electric vehicle intelligent protection switch. Background technique [0002] In the past ten years, my country's electric bicycles, electric motorcycles, and electric vehicles (hereinafter referred to as electric vehicles) have developed rapidly. Due to the energy saving, environmental protection and convenience of electric vehicles, they have become a popular and indispensable means of transportation for residents all over the country. An average of 50 million electric vehicles are sold nationwide every year. In the past ten years, nearly 500 million units have been sold in the national market. However, due to the structure and circuit characteristics of the electric vehicle itself, there is no perfect circuit protection system at present, which cannot fully detect the safety status of the electric vehicle when riding, and spontaneous combustion often occurs duri...

AI Technical Summary

Problems solved by technology

Afraid of causing greater casualties and loss of people's property

The reason is that although there is a protective switch on the electric vehicle at present, it is a mechanical air switch transplanted on the general circuit, which is not well combined with the structure, production process and circuit of the electric vehicle, and cannot intelligently detect and prevent the electric Car burning accidents occur when driving, parking and charging

When the electric vehicle spontaneous combustion accident has occurred, the air switch has not yet tripped, that is to say, the smart switch on the electric vehicle that can completely detect and control the driving state of the electric vehicle is still a blank both domestically and internationally.
