Description
technical field [0001] The invention relates to the technical field of thermal management systems, in particular to a thermal management system of an electric vehicle. Background technique [0002] At present, the cruising range of electric vehicles is the bottleneck of the development of this industry. In addition to breaking through the existing battery technology, the management and optimization of vehicle energy consumption is another way to implement and optimize. The existing energy management of electric vehicles generally only considers some single functions. For example, some use a double evaporator system to assist heating, some use air cooling to dissipate heat from the battery, and some use liquid cooling to dissipate heat from the battery. Some use liquid cooling to dissipate heat from the motor and power components, and some consider the natural air cooling of the motor and power components. Such a single system cannot effectively evaluate the energy utilizatio...
