Problems solved by technology

However, electric vehicles use high levels of current for long-distance driving and high-power / high-performance driving, so even if electric vehicles use a water cooling system whose cooling performance is greater than that of an air cooling system, adding an air conditioner compressor (or radiator) and the capacity of the battery cooler to cool the heat generated in the single battery is also unavoidable

Embodiment Construction

[0013] It should be understood that the term "vehicle" or "vehicular" or other similar terms as used herein generally includes motor vehicles such as passenger cars including sport utility vehicles (SUVs), buses, trucks, various commercial Vehicles, marine craft including boats and ships of all kinds, aircraft, etc., and include hybrid vehicles, electric vehicles, plug-in hybrid electric vehicles, hydrogen vehicles, and other alternative fuel vehicles (e.g., derived from sources other than petroleum fuel from outside resources). As referred to herein, a hybrid vehicle is a vehicle that has two or more sources of power, such as a vehicle that has both gasoline and electric power.

[0014] The terminology used herein is for describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly dictates otherwise. It should be ...

Abstract

A battery cooling device for a vehicle is provided to cool a battery cell. The device includes a phase change material (PCM) that cools the battery cell and is disposed to exchange heat with the battery cell and cooling water for cooling the phase change material is disposed to exchange heat with the phase change material. Thus, the phase change material is heated by heat generation of the batterycell and at the same time the phase change material is cooled by heat absorption of the cooling water thereby facilitating continuous phase change of the phase change material.

Description

technical field [0001] The present invention relates generally to a battery cooling device for a vehicle, and more particularly to a battery cooling device for a vehicle using a phase change material to cool a single battery. Background technique [0002] Recently, electric vehicles require long-distance driving, high-power / high-performance driving, and fast charging. A battery system, which is the energy source of an electric vehicle, has a high level of current flowing in its cells, which causes it to generate heat greater than the capacity of conventional battery cooling devices installed in existing electric vehicles. Since the heat generated in a single cell has an adverse effect on battery life, it is necessary to keep the heat within a predetermined temperature range. [0003] To maintain the temperature of the cells, existing electric vehicles use an air cooling system or a water cooling system. In particular, the air cooling system uses a cooling fan to supply the...
