Electric vehicle charging safety automatic control and abnormity early warning system

Abstract

The invention discloses an electric vehicle charging safety automatic control and abnormity early warning system, which belongs to the technical field of electronics, and comprises the following modules: a temperature sensor for monitoring an electric charging state; and the MCU chip is in data connection with the temperature sensor, judges the working state of the battery according to the charging time and the current change, and uploads the data to a platform and triggers an alarm if the battery is abnormal. According to the electric vehicle charging safety abnormity early warning system, when electric vehicle charging safety abnormity early warning is carried out, a monitoring mode is started for the charging process and the charging state, when a temperature sensor detects that the temperature is abnormal, charging of a control device is cut off, the situation that a circuit breaks down due to overcharging, and consequently the circuit is on fire is avoided, and when charging is cut off, the system also uploads data; the early warning information is pushed to the APP of the vehicle owner, the vehicle owner is reminded to turn off a main power supply, eliminate a fault source and avoid harm expansion, and the early warning information is stored in a platform list, so that a platform manager can check the early warning times and the early warning time conveniently.

Description

technical field [0001] The invention belongs to the technical field of electronics, and in particular relates to an electric vehicle charging safety automatic control and abnormal early warning system. Background technique [0002] The charging process of the lithium battery of an electric vehicle is a high-probability process of combustion or explosion. Once the battery is burned, it will not only destroy its own vehicle, but also affect the surrounding vehicles and buildings. Destroy surrounding vehicles and buildings. [0003] In the prior art, the safety protection measures for the charging of electric vehicles are not perfect, and the risk elimination work after circuit faults is not taken seriously. The fire caused by the charging faults of electric vehicles causes great harm. SUMMARY OF THE INVENTION [0004] In order to overcome the defects in the prior art, the purpose of the present invention is to provide an electric vehicle charging safety automatic control an...
