Electric vehicle failure diagnosis, maintenance and training device and using method thereof

Abstract

The invention provides an electric vehicle failure diagnosis, maintenance and training device and a using method thereof. By adding a diagnosis and failure communication gateway, arranging a pluralityof diagnosis and failure removal operating modules outside a vehicle and arranging a plurality of measuring modules outside the vehicle, vehicle diagnosis, vehicle signal measurement and failure removal are provided in a sharing way, wherein the diagnosis and failure communication gateway is separately connected with a failure setting and removal execution module and a CAN communication bus in the vehicle. The device can allow a plurality of students to make diagnosis, carry out maintenance and remove failures at the same time, and the device utilization rate is improved; when the failure setting and removal execution module is arranged in the vehicle, and failure setting operation is conducted in a wireless mobile way, it can be achieved that the vehicle is moved in a failure state so asto observe a dynamic failure phenomenon.

Description

technical field [0001] The invention relates to the field of training devices for fault diagnosis and maintenance of electric vehicles, in particular to a training device for fault diagnosis and maintenance of electric vehicles and a method for using the same. Background technique [0002] Fault diagnosis and maintenance of electric vehicles is a compulsory course for new energy vehicle majors in vocational colleges, and it is a practical training course. Usually, teachers artificially set the faults of electrical devices or circuits, and let students diagnose, measure and solve the faults, so as to achieve the goal of combining theory and practice. as reference figure 1 , In order to avoid high-voltage risks, in the actual training of fault diagnosis and maintenance of electric vehicles, fault settings for high-voltage cables and high-voltage electrical appliances will not be performed. Instead, fault settings are made for the low-voltage control components and low-voltag...

AI Technical Summary

Problems solved by technology

[0005] 1) Low equipment utilization: only one diagnostic instrument, one measurement module and one troubleshooting module can work at the same time, that is, only one student can operate each training session, and multiple students cannot operate at the same time

The utilization rate of equipment is low, which is not conducive to carrying out multi-person teaching

[0006] 2) The fault setting module needs to be connected externally, which results in limited application and performance: the fault setting module is placed outside the vehicle and must be wired to set the fault. Happening);
