Electric vehicle distributed networked test system and method based on cloud platform

Abstract

The invention provides an electric vehicle distributed networked test system and method based on a cloud platform. The system comprises a cloud computing platform and a plurality of remote test racks.The number of the remote test racks is at least two, and the remote test racks form a remote distributed networked structure and transmit test data to the cloud computing platform. The cloud computing platform carries out bidirectional data communication with a remote test bench in real time, and the cloud computing platform is configured to receive the test data in real time, perform data cleaning, data class cleaning, data fusion and data mining, extract useful data information from the test data, establish a corresponding data model and a mechanism model on the cloud computing platform according to historical data and a control object mechanism, and perform control for different test racks to complete fault diagnosis and early warning.

Description

technical field [0001] The disclosure belongs to the field of testing electric vehicle power systems and key components, and relates to a distributed networked testing system and method for electric vehicles based on a cloud platform. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] The inventor found that in the field of new energy vehicles, especially hybrid electric vehicles, there are many types of test benches for power systems and their components, mainly including hybrid system test benches, motor drive system test benches, engine test benches, Power battery charge and discharge test benches, gearbox and transmission system test benches, driver control test benches, etc. However, these test benches mentioned above are independent and have single functions, so it is difficult to build them in a limited space A complete vehicle test ...

Problems solved by technology

[0003] The inventor found that in the field of new energy vehicles, especially hybrid electric vehicles, there are many types of test benches for power systems and their components, mainly including hybrid system test benches, motor drive system test benches, engine test benches, Power battery charge and discharge test benches, gearbox and transmission system test benches, driver control test benches, etc. However, these test benches mentioned above are independent and have single functions, so it is difficult to build them in a limited space A complete vehicle test platform, and these benches are limited to local testing, the test data needs to be analyzed and processed offline, and the calculation method is relatively simple, and there are great deficiencies in function, calculation amount, and calculation speed, which lead to test results and The actual vehicle operation error is relatively large
