Testing system of power assembly

Abstract

The invention provides a testing system of a power assembly, and belongs to the technical field of testing of power systems. The testing system at least comprises a power testing machine, a first control module, an upper computer module and an extension control protocol developing module, wherein the first control module is used for correspondingly controlling the power testing machine, the upper computer module is configured to define different working conditions according to a state machine architecture so as to continuously switch between different working conditions, and perform communication with a power assembly controller in any state according to a ASAM-MCD (association for standardization of automation and measuring systems - measurement, calibration and diagnosis) communication protocol, the extension control protocol developing module is used for developing an extension control protocol between the upper computer module and the first control module, and the remote communication is performed between the first control module and a second control module which is integrated into the upper computer module according to the extension control protocol, so as to control the power testing machine on the basis of the second control module. The testing system has the advantages that the compatibility and the extendibility are good, the continuous switching between different working conditions is easy, the cost is low, and the testing period is short.

Description

technical field [0001] The invention belongs to the technical field of power system testing, and relates to a power assembly testing system, in particular to a power assembly testing system suitable for continuous switching tests in different working conditions. Background technique [0002] In the early stage of the development of the power system, it is usually necessary to conduct various tests on the power train (especially the electric drive transmission (EDU)) to grasp the performance of the power system. Therefore, a high-performance test system is required in this field, especially in the field of new energy vehicle testing. [0003] Take the electric drive transmission (EDU) as an example. At present, the test system of high-performance electric drive transmission is costly (up to tens of millions of RMB) and the construction period is long. Therefore, many automobile manufacturers will choose to supply with domestic test systems Cooperate with suppliers to build t...

Problems solved by technology

[0003] Take the electric drive transmission (EDU) as an example. At present, the test system of high-performance electric drive transmission is costly (up to tens of millions of RMB) and the construction period is long. Therefore, many automobile manufacturers will choose to supply with domestic test systems Cooperate with suppliers to build their own corresponding test systems to reduce costs and shorten the construction period

However, many test systems are based on their own software architecture, and can only complete some common tests and manual tests. For tests that require continuous switching between different working conditions, the system openness and software compatibility are far from enough, not only difficult to complete, And the test time is long

This will restrict the development cycle of new energy vehicles
