New energy automobile overall controller and battery controller joint test system

Abstract

The invention relates to the technical field of new energy automobiles, and provides a new energy automobile overall controller and battery controller joint test system, which comprises an upper computer, a hub, an overall controller test cabinet, a battery controller test cabinet, an overall controller fault injection box, a battery controller fault injection box, an overall controller and a battery controller. Tedious steps for testing pins of the overall controller and the battery controller manually one by one can be avoided, and thus the test cycle can be greatly shortened; the problem that when a closed-loop test is carried out on the overall controller or the battery controller alone, the problem that a communication function test between a real controller and a virtual controller is incomplete can be solved; the problem that test accuracy of the controller is influenced when the closed-loop test is carried out on the overall controller or the battery controller alone can be solved; and a problem exposed can be timely found out and handled, the product quality is effectively enhanced, the product test cycle is shortened, and enterprise cost is saved.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a new energy vehicle vehicle controller and battery controller joint testing system, which is used for joint testing of the new energy vehicle vehicle controller and battery controller. Background technique [0002] With the progress of society and the improvement of people's living standards, people's demand for automobiles is getting higher and higher, resulting in the rapid growth of my country's automobile production and sales. While enjoying the convenience brought by cars, people encounter some more and more unbearable problems, such as more frequent smog and higher concentrations of PM2.5, and now 50% of urban air pollution sources are cars exhaust. Under such circumstances, new energy vehicles are on the horizon, and the research and development direction of major OEMs is gradually tilting towards new energy vehicles. Pure electric vehicles not only consume ...
