Problems solved by technology

Obviously, pure air cooling cannot meet the cooling needs of high-power power batteries, and a cooling system must be specially designed to suit high-power power batteries to ensure efficient cooling
Moreover, if air is introduced from the passenger compartment for cooling, it will affect the cooling capacity of the air conditioner in the passenger compartment, and may even lead to an increase in the temperature of the passenge

Embodiment Construction

[0021] In order to make the purpose, features and advantages of the present invention more obvious and understandable, the specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0022] see figure 1 As shown, an electric drive vehicle (not shown) includes a power storage battery thermal management system 1 , air conditioning systems 2 and 3 and a power storage battery 10 . The air conditioning system includes a refrigeration system 2 and a heating system 3 .

[0023] The refrigeration system 2 includes an electric compressor 20 , an air conditioner condenser 22 , a second shut-off valve 23 , a second expansion valve 24 and an evaporator 25 connected in sequence through a conduit 21 . The evaporator 25 is used for heat exchange with a space that needs to use cold air, such as the passenger compartment, to provide refrigeration. The second expansion valve 24 plays the role of throttling and red...

Abstract

The invention discloses a power accumulator heat management system and a vehicle therewith. The power accumulator heat management system comprises a first heat radiator and a second heat radiator, wherein the first heat radiator absorbs heat generated by a power accumulator and emits the heat to environmental air, and the second heat radiator absorbs the heat generated by the power accumulator and can radiate the heat in a heat exchange mode through a refrigerant flowing by the second radiator. The power accumulator heat management system provided by the invention can match a suitable cooling system for the power accumulator, not only ensures the suitable cooling of the power accumulator, but also ensures the energy-saving effect of a vehicle using the power accumulator heat management system so that the vehicle can run in the most reliable and energy-saving state.

Description

【Technical field】 [0001] The invention relates to automobiles, in particular to an automobile with a power battery and a heat management system for the power battery. 【Background technique】 [0002] The power of the traction battery in the previously listed vehicles is generally relatively small, and the cooling method adopts pure air cooling, or introduces air from the passenger compartment to cool the traction battery. The air cooling method has a small cooling capacity and is suitable for small power batteries on weak hybrid vehicles. Obviously, pure air cooling cannot meet the cooling needs of high-power power batteries, and a cooling system must be specially designed to suit high-power power batteries to ensure efficient cooling. Moreover, if air is introduced from the passenger compartment for cooling, it will affect the cooling capacity of the air conditioner in the passenger compartment, and may even cause the temperature of the passenger compartment to rise, reduci...
