Abstract

The invention relates to the technical field of thermal management, and discloses an electric vehicle thermal management system. The electric vehicle thermal management system comprises a battery packfirst circuit and a thermal generating component first circuit, wherein the battery pack first circuit comprises a first liquid storage device, a first pump, a battery pack, an electric heater and afirst thermal exchange flow path of a combination thermal exchanger, which are connected in series through a pipeline, the thermal generating component first circuit comprises a second liquid storagedevice, a second pump, a second thermal exchange flow path of the combination thermal exchanger, and a thermal generating component which are connected in series through a pipeline, and the first thermal exchange flow path and the second thermal exchange flow path of the combination thermal exchanger can realize thermal exchange. The electric vehicle thermal management system comprehensively utilizes the thermal source of the whole vehicle to uniformly manage the thermal management and distribution of the whole vehicle, thereby improving the efficiency of heating the battery in a low temperature environment, saving the energy of the whole vehicle, and correspondingly extending the endurance capacity of the electric vehicle in a low temperature environment.

Description

technical field [0001] The invention relates to the technical field of thermal management, in particular to a thermal management system of an electric vehicle. Background technique [0002] The electric vehicle thermal management system includes the thermal management of the passenger compartment, the thermal management of the battery pack, and the thermal management of components such as motors, motor controllers, DC / DC converters, and on-board chargers (OBCD). At present, electric vehicles generally adopt a solution that integrates the passenger compartment and the battery pack for centralized thermal management, while separate components such as the motor, motor controller, DC / DC converter, and on-board charger (OBCD) are used. thermal management scheme. [0003] Since electric vehicles lack the heat source of the engine of traditional fuel vehicles, how to efficiently heat the passenger compartment and battery in a low-temperature environment is still a technical diffic...
