Electric vehicle test bench

Abstract

The invention discloses an electric vehicle test bench, comprising a test platform; a hardware-in-the-loop HIL simulation platform in connection with the test platform; and a battery environment testdevice, a charging pile simulation device and a motor bench, which are respectively connected with the hardware-in-the-loop HIL simulation platform through a test injection line, wherein the test platform controls switching between a hardware-in-the-loop test and a real vehicle test through a signal interaction with the hardware-in-the-loop HIL simulation platform and respectively controls the working state of one or more of the three of the battery environment test device, the charging pile simulation device and the motor bench through the hardware-in-the-loop HIL simulation platform. According to the embodiment of the present invention, the real finished vehicle parts are used to build a test bench in three-electricity joint of the battery, the motor and electric control, thereby achieving rapid switch between the hardware-in-the-loop and the real-vehicle test, which not only has the flexibility and convenience of the hardware-in-the-loop but also has the reality of the real vehicletest, so as to avoid potential dangers during the real vehicle testing process.

Description

technical field [0001] The invention relates to the technical field of electric vehicle testing, in particular to an electric vehicle test bench. Background technique [0002] As the core architecture of pure electric vehicles, batteries, motors, and electronic controls are collectively referred to as three electric vehicles, and the safety and reliability of their software are very important. At present, the usual testing methods in the industry mainly include Hardware-In-the-Loop (HIL) testing and actual vehicle testing. The hardware-in-the-loop testing stage mainly performs functional verification, which cannot effectively evaluate the performance of the entire vehicle. Verification; the actual vehicle test stage mainly carries out performance verification and user scenario testing, but the actual vehicle test is already at the end of the entire development process, and problems found in the actual vehicle test will bring great pressure to the entire project development c...
