The invention relates to the technical field of auto parts and components structures, in particular to an electric vehicle engine room arrangement structure with a battery thermal management system. The electric vehicle engine room arrangement structure comprises a cooling system for cooling a battery pack and a heating system for heating the battery pack. The cooling system comprises a cooling degassing chamber, a first plate-type heat exchanger and a cooling water pump. The heating system comprises an air-conditioning degassing chamber, a PTC heater, a heating water pump and a second plate-type heat exchanger. The cooling degassing chamber, the first plate-type heat exchanger, the second plate-type heat exchanger and the cooling water pump are sequentially connected in series to form a closed circuit cooling system by a first pipeline structure. The air-conditioning degassing chamber, the PTC heater, the heating water pump and the second plate-type heat exchanger are sequentially connected in series to form a closed circuit heating system by a second pipeline structure. The battery thermal management system is simple in structure, reasonable in space optimization, convenient in integral installation, reliable in positioning, high in assembly precision and high in modularization degree.
Description
technical field [0001] The invention relates to the technical field of auto parts structure, in particular to an arrangement structure of an electric vehicle cabin with a battery thermal management system. Background technique [0002] With the rapid development and popularization of electric vehicles, the battery pack, as the main energy storage device of the battery pack on the electric vehicle, is a key component of the electric vehicle, and its performance directly affects the performance of the electric vehicle. At present, batteries generally have disadvantages such as low specific energy and specific power, short cycle life, and high temperature-affected performance. Because the battery pack will work in a relatively harsh thermal environment for a long time, it will cause uneven temperature everywhere and affect the consistency of the battery cells, thereby reducing the battery charge and discharge cycle efficiency and affecting the power and energy performance of th...
