Embodiment Construction

[0015] In order to make the present invention more comprehensible, preferred embodiments are described in detail below with accompanying drawings.

[0016] combine figure 1 , a new energy vehicle three-electric system semi-physical simulation test platform provided by the present invention includes a load motor 1, a front-end module 2, an environment chamber 3, a motor under test 4, an MCU 5, a real-time data acquisition module 6, an industrial control computer 7, and a battery Simulator 8, variable frequency drive 9, water cooling unit 10.

[0017] The load motor 1 , the front-end module 2 and the variable frequency driver 10 work together to form a simulated load of real-time road conditions. The front-end module 2 of the present invention converts the driving condition of the vehicle into the load motor condition based on the vehicle model, the road model, and the driver model, and uses the motor speed and torque as the control parameters of the load motor. The vehicle sp...

Abstract

The present invention provides a new energy automobile EIC system semi-physical simulation test platform. The platform comprises a battery simulator and a frequency conversion driver; a real-time road condition simulation load; and a real-time data collection system configured to collect data of a tested motor in real time and return the data to an upper computer. The new energy automobile EIC system semi-physical simulation test platform integrates the rack simulation system and the electronic control system prototype (or a simulation electronic control system) of a BMS prototype system (or a simulation BMS system) to provide a new energy automobile and road semi-object platform built in a laboratory for research personnel. On this platform, the independent test of each subsystem can be performed, and the verification, the optimization and the parameter calibration of the automobile control strategy and the automobile power performance are performed, so that the great amount of actual automobile and road tests are replaced.

Description

technical field [0001] The invention relates to a unified platform for joint research and development, debugging and verification of three electric systems. Background technique [0002] Various types of existing test benches are developed and designed for an independent subsystem in the three-electric system, such as battery test systems, EV motor test benches, VCU development and verification tools, etc. R&D personnel lack a unified platform for joint R&D, debugging and verification of the three electric systems, so they can only verify and optimize the overall performance and strategy of the system in the road test after loading. Contents of the invention [0003] The purpose of the present invention is to test and verify the power system of the new energy vehicle as a single whole, and provide a basic platform for the V-shaped development mode of the power train. [0004] In order to achieve the above object, the technical solution of the present invention is to provi...
