Description
technical field [0001] The invention belongs to the technical field of thermal management systems of automobiles, and in particular relates to an air-conditioning battery integrated thermal management system based on mixed phase change materials for pure electric vehicles and hybrid electric vehicles. Background technique [0002] In a low temperature environment, too low temperature will affect the battery discharge performance, which may lead to insufficient power output of the electric vehicle; in a normal temperature environment, the battery pack will frequently perform charging and discharging activities during the driving of the electric vehicle, and the battery will continue to generate heat during this process , leading to a rise in battery temperature and affecting the working efficiency of the battery; in a high-temperature environment, if the battery cannot dissipate heat in a timely and effective manner, the battery may be in danger of thermal runaway. Therefore,...
