Abstract

The invention discloses a comprehensive test platform and a comprehensive test method for a dynamic system of a fuel cell hybrid electric vehicle. The platform comprises an industrial control console operation unit, a lithium cell pack unit, a fuel cell unit, a direct-current / direct-current (DC / DC) converter, a tested motor unit, an alternating-current power dynamometer unit, a switching execution unit and a resistive electronic controllable load, wherein the industrial control console operation unit communicates with all the other units through a data acquisition card, a controller area network (CAN) card and a CAN bus, and simulates to manage the whole comprehensive test platform. According to the comprehensive test platform and the comprehensive test method, comprehensive test functions of testing the performance of a fuel cell system, a lithium cell pack and a tested motor and managing the energy of the dynamic system is realized.

Description

technical field [0001] The invention belongs to the field of electric vehicle testing and testing, in particular to a fuel cell hybrid electric vehicle power system comprehensive testing platform and testing method. Background technique [0002] Electric vehicles have low energy consumption and low emissions, and have become a current research hotspot. A hybrid electric vehicle is equipped with two or more power sources. The on-board power sources include: internal combustion engine, power storage battery, fuel cell, solar cell, etc. Vehicles that use internal combustion engines and batteries as hybrid power sources are called oil-electric hybrid electric vehicles; vehicles that use batteries, fuel cells, and solar cells as power sources are called electric-electric hybrid electric vehicles. [0003] The "Time" magazine of the United States listed fuel cells as the top ten high-tech technologies that will change the future life of human beings. At present, all countries in ...
