The invention provides an electric vehicle thermal safety management system and method with a composite jetting device. From the perspective of improving the heat exchange efficiency and the structural light weight, the electric vehicle thermal safety management system with the composite jetting device comprises various structural devices which are arranged in a passenger compartment, a battery compartment and a power compartment respectively and used for achieving temperature adjustment. The electric vehicle thermal safety management system with the composite jetting device has reasonable structural arrangement, so that the cooling efficiency is improved by 3-4 times, the cost can be reduced by 30%, the weight can be reduced by 75%, and the purposes of improving the structural light weight and improving the safety, comfort and reliability are achieved.
Description
technical field [0001] The present application relates to the technical field of battery thermal safety prevention and control, and in particular to an electric vehicle thermal safety management system and method with a compound injection device. Background technique [0002] With the establishment of the strategic position of my country's new energy vehicle industry during the "13th Five-Year Plan" period, the mileage and safety issues of electric vehicles have attracted widespread attention. Among them, the auxiliary energy consumption of vehicle air conditioners in summer operation, winter heating and power battery low-temperature preheating and high-temperature cooling can account for 33% of the total energy consumption of electric vehicles. In addition, the use of large power battery modules, technological progress in high specific energy output, and electric vehicles put forward higher requirements for the safety and reliability of electric vehicle thermal management. ...
