Problems solved by technology

[0003] For the system that adopts air-conditioning double steam system for battery cooling, the water temperature drops quickly, and the temperature difference between the battery core and the battery core is relatively large, which has a certain impact on battery life. Turning it back on consumes power and has a negative impact on the perceived comfort of the passenger cabin occupants during this switching process

Abstract

The invention provides a thermal management system, a battery thermal management system, an electric vehicle and a hybrid power vehicle. The thermal management system comprises a heating/refrigerating loop and a heat/cold storage loop which exchanges heat with the heating/refrigerating loop, wherein a circulating medium of the heat/cold storage loop is a phase change cold storage material; when the heating/refrigerating loop is in a heating mode and the temperature of the circulating medium of the heat/cold storage loop is not lower than the phase change temperature, the heating/refrigerating loop stops heating; when the heating/refrigerating loop is in a refrigerating mode and the temperature of the circulating medium of the heat/cold storage loop is not higher than the phase change temperature, the heating/refrigerating loop stops refrigeration. According to the thermal management system, the purpose of thermal management can be achieved.

Description

technical field [0001] The invention relates to a thermal management system, a battery thermal management system, an electric vehicle and a hybrid vehicle. Background technique [0002] At present, there are mainly two types of battery thermal management systems: air-cooled and water-cooled. The air-cooled system is mainly equipped with fans, inlet and outlet air ducts, etc. It has a relatively simple system structure, directly uses the existing environment, and the temperature controlled by the battery core is relatively high. The air-cooled battery pack has a large volume, which is inconvenient for the whole vehicle layout. The water-cooled system is mainly equipped with heat exchangers, pipelines, water pumps, etc. The temperature of the battery core is easy to control, and the temperature is low, which is beneficial to the life of the battery. Compared with the importance and criticality of the battery to the electric vehicle, the cooling format is recommended. [000...
