Device and method for analyzing fault diagnosis and records of electric vehicle at charging station

Abstract

The invention discloses a device and a method for analyzing the fault diagnosis and records of electric vehicles at a charging station. Existing monitoring center, charging devices and electric vehicles are utilized, and simultaneously the software function of each electronic control module on the monitoring center, the charging devices and the electric vehicles is added through unified communication protocol specifications, the function can be added but the cost is hardly increased in initial planning, the state messages, such as fault states, charging frequency, charging time and charging electric quantity, of the electric vehicles running on lines can be collected in real time by adding the corresponding function in product software as long as the unified communication protocol specifications are followed, and operating data are collected by monitoring VIN codes of the vehicles and analyzing the operating state of each electric vehicle, so that real time monitoring and optimized dispatching are realized.

Description

technical field [0001] The invention relates to the technical field of vehicle fault diagnosis and analysis, in particular to an electric vehicle fault diagnosis and record analysis device and method thereof by a charging station. Background technique [0002] Electric vehicles refer to vehicles powered by vehicle-mounted power supplies, driven by motors to drive wheels, and meeting the requirements of road traffic and safety regulations; in order to maintain my country's energy security, improve the atmospheric environment, improve the competitiveness of the automobile industry, and realize With leapfrog development, electric vehicles are in full swing in our country. [0003] At present, the charging device mainly charges the car through AC and DC, and does not have the function of diagnosing the car, and does not have the function of collecting and analyzing the status of the car; the electric car is in the development stage, and the probability of failure is relatively hi...

AI Technical Summary

Problems solved by technology

[0004] At present, charging stations or charging piles mainly charge electric vehicles through AC and DC, and do not have the function of diagnosing the vehicle, let alone collecting and analyzing the status of the vehicle; especially for public transportation vehicles such as electric buses with fixed routes, Bus companies need to collect and control the status of operating vehicles in real time, and control and analyze information such as vehicle failure, charging frequency, charging time, charging power, etc., to realize real-time monitoring and optimal scheduling of electric buses
