Power accumulator heat management system and vehicle

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...

AI Technical Summary

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 passenger compartment, reducing the comfort of the passenger compartment

[0003] Vehicles equipped with high-power traction batteries, such as strong hybrid vehicles and electric vehicles, often generate heat due to the high output power of the traction batteries, which will cause the temperature of the traction batteries to rise. When the temperature is too high, it is easy to cause abnormal operation. There is even a risk of explosion
