Abstract

The invention discloses a fuel consumption assessment device for a fuel cell vehicle, belonging to the technical field of new energy vehicle performance test and assessment. The fuel consumption assessment device is used for assessing the fuel consumption and economical efficiency of the fuel cell vehicle, and comprises a gas source bottle rack and a pipeline system connected with the gas source bottle rack, wherein the pipeline system is connected with the fuel cell vehicle; the gas source bottle rack comprises a gas bottle bracket, a temperature sensor and a pressure sensor; the gas bottle bracket is used for accommodating gas bottles, and the temperature sensor and the pressure sensor are used for measuring the gas in the gas bottles, and the fuel consumption is calculated based on the measuring results of the temperature sensor and the pressure sensor; the fuel consumption assessment device also comprises a weighing device; and the weighing device comprises a windproof and shockproof tank body, a precision balance and a balance weighing auxiliary device, and is used for carrying out fine measurement on the fuel consumption. The fuel consumption assessment device can realize measuring the fuel consumption of heavy type fuel cell vehicles and assessing the fuel economy of the heavy type fuel cell vehicles.

Description

Technical field [0001] The invention belongs to the technical field of performance testing and evaluation of new energy vehicles, and particularly relates to a fuel consumption evaluation device for fuel cell vehicles. Background technique [0002] With the deepening of domestic fuel cell vehicle research, the continuous expansion of the scope of demonstration operation and the development of lease use, more and more urgent requirements are put forward for the evaluation method of fuel cell vehicle performance. The accurate measurement of fuel consumption and economic evaluation play a very important role in the performance evaluation of fuel cell vehicles. Due to the particularity of hydrogen fuel, the fuel consumption measurement methods used in traditional internal combustion engine vehicles, such as the carbon balance method, are not suitable for hydrogen fuel. Therefore, it is necessary to study a fuel consumption detection method suitable for hydrogen. Major automobile man...
