Background
As an important component of the current new energy automobile, the fuel cell automobile is a nonlinear, multivariable and time-varying complex system, and the thermal management level of the fuel cell automobile determines the performance and the service life of the whole automobile. The fuel cell can maintain high energy conversion efficiency when being stabilized at 60-80 ℃. When the temperature of the fuel cell is too low during operation, the impedance of the cell is increased, the polarization is large, the overall performance of the fuel cell is reduced, and the efficiency is reduced; when the operating temperature of the fuel cell is too high, the proton exchange membrane is dehydrated, and safety accidents are easily caused. For the thermal management of the power battery, the performance of the battery is affected by the over-high or under-low temperature during the charging and discharging processes of the battery, and particularly, the battery may explode when the temperature of the battery is over-high. Regarding the thermal management of the driving motor, the motor system as an energy conversion unit of a fuel cell vehicle is converted into heat due to inevitable loss during the energy conversion process, and if the heat is not dissipated in time, the service life and the service performance of the motor are affected.
How to rapidly increase the temperature of the fuel cell in a low-temperature environment is a hot research point of current thermal management. Existing fuel cell vehicles, including toyota Mirai and modern NEXO, are heated using conventional PTC. The PTC heating can be used for rapidly increasing the temperature of the fuel cell, but the problem of large energy consumption of the whole vehicle in a low-temperature environment is also brought. Therefore, a reasonable fuel cell vehicle integrated thermal management system and control method are needed to improve energy utilization and overall vehicle economy. The invention discloses a fuel cell heat management system with phase change heat storage and preheating functions, which can store the residual heat of a fuel cell in a phase change heat exchanger and is used for preheating the fuel cell by a liquid circuit and a gas circuit or insulating the fuel cell, for example, Chinese patent publication No. CN111463453A, publication No. 2020-07-28; in addition, the waste heat of the fuel cell can heat the air inlet, the lithium battery or the passenger cabin, so that the energy utilization rate is improved. Also, for example, patent application publication No. CN111855247A, published as 2020-10-30, discloses an electric vehicle heat pump air conditioner testing system and an electric vehicle thermal management test bench. The heat pump air-conditioning system is used for testing the heat pump air-conditioning system of the electric vehicle, the heat pump air-conditioning system comprises a compressor, a four-way reversing valve, an in-vehicle heat exchanger, an expansion valve and an out-vehicle heat exchanger, the energy consumption of the whole vehicle can be further optimized, the energy-saving aim is achieved, and the detection accuracy and efficiency are improved. None of the above patents take into account thermal management of the heat pump air conditioner with other components of the fuel cell vehicle.
In order to overcome the technical defects, the invention provides a fuel cell automobile integrated heat management system based on a heat pump air conditioner and a control method thereof.
