Abstract

The invention discloses a phase-change material energy-storage based cooling apparatus for a power battery. The cooling apparatus comprises a power battery, a cooling liquid circulation module and a refrigeration module, wherein the power battery is connected with the cooling liquid circulation module to form heat exchange circulation; heat exchange is carried out between the cooling liquid circulation module and the refrigeration module; the power batter is electrically connected with the cooling liquid circulation module and the refrigeration module separately; and according to the phase-change material energy-storage based cooling method for the power battery, the to-be-cooled power battery pack is cooled by the phase-change material energy-storage based cooling apparatus for the power battery. The cooling apparatus has the advantages of reasonable structure, high temperature control precision, high radiation capability, convenience in use, low power consumption and small size, and is more applicable to popularization and application in the temperature control of the power battery pack.

Description

technical field [0001] The invention belongs to the technical field of cooling and power supply, and relates to a power battery cooling method and device based on phase change material energy storage. Background technique [0002] An electric vehicle refers to a vehicle powered by a vehicle-mounted power supply, driven by a motor to drive the wheels, and conforming to the requirements of road traffic and safety regulations. It uses electricity stored in the battery to start. [0003] Provide electric energy for the driving motor of the electric vehicle, and the electric motor converts the electric energy of the power supply into mechanical energy. The most widely used power source is lead-acid battery, but with the development of electric vehicle technology, lead-acid battery is gradually replaced by other batteries due to its low energy, slow charging speed and short life. The power sources under development mainly include sodium-sulfur batteries, nickel-cadmium batteries...
