Testing method for economic efficiency of fuel cell hybrid electric vehicle

Abstract

The invention provides a testing method for economic efficiency of a fuel cell hybrid electric vehicle. The method comprises the following steps of performing hardware-in-loop simulation on a to-be-tested fuel cell hybrid electric vehicle to obtain fuel cell current data and storage battery energy consumption under a preset working condition; connecting fuel cell with an electronic load on a fuel cell testbed, and controlling the output current of the electronic load according to the current data to enable the intensity of the output current of the electronic load to be consistent with the current data; measuring the first hydrogen consumption of the fuel cell for supplying energy for the electronic load during testing; working out total hydrogen consumption according to the battery energy consumption and the first hydrogen consumption. Through the method provided by the invention, under the condition that the economic efficiency of the fuel cell hybrid electric vehicle needs to be repeatedly tested, multiple bench tests or road tests do not need to be conducted; the required current data can be acquired through the hardware-in-loop simulation; only the fuel cell needs to be tested, so that the testing process can be simple.

Description

technical field [0001] The invention relates to the technical field of automobile performance testing, in particular to an economical testing method of a fuel cell hybrid electric vehicle. Background technique [0002] With the development of fuel cell hybrid vehicles, the testing of hybrid vehicles is becoming more and more important. The economical test of fuel cell hybrid electric vehicles is a very important part of hybrid electric vehicle testing. [0003] In the prior art, the economical test of the fuel cell hybrid electric vehicle is to measure the hydrogen consumption in a bench test or a road test. Every time a measurement is taken, a bench or road test must be performed to put the entire system into operation. [0004] It can be seen from the above description that in the economical testing method in the prior art, a bench or road test is required for each measurement, and the testing process is complicated. Contents of the invention [0005] The invention pr...
