Description

  The present invention relates to the field of temperature control of a secondary battery, and more particularly to a high-power battery or capacitor module that uses an electrolyte as a coolant.

Electric vehicles (EV), hybrid cars (HEV), plug-in hybrid cars (Plug-in HEV) have already been used to mitigate the problems of pollution (air pollution, etc.) caused by vehicles using fossil fuel gasoline and diesel oil. Is becoming the development trend of automobiles in the future.
In general, a driving battery used in an automobile includes many battery cells, which are called battery cells. Many of the battery cells used in a large amount for the drive battery are lithium ion batteries (LIBs). Usually, a plurality of packaged battery cells are connected in series / parallel to each other, and then further packaged. Configures a module / battery pack.
A plurality of battery modules / battery packs are usually used based on the power required for the automobile, and these battery modules / battery packs contain thousands of battery cells.

As a technical problem that cannot be avoided by vehicles using these electric powers, there is a problem of heat generation in the charge / discharge operation process of the drive battery. Temperature is an important factor that affects the life and safety of the drive battery.If the battery temperature is too high, side reactions inside the battery become severe, shortening the battery life, and in severe cases, thermal runaway May cause safety problems such as ignition and explosion.
Suitable operating temperatures for lithium ion batteries are between 25 ° C and 40 ° C. For this reason, temperature management of the drive battery has become the focus of research.

In many applications, such as electric vehicles, high power batteries and / or capacitor systems are required.
There is currently no method other than using a cooling medium, such as air, liquid, or solid, around the packaged battery and / or capacitor unit to provide proper temperature management.

There are three types of temperature control methods for driving batteries using known lithium ion batteries: air cooling, liquid cooling, and phase change material (PCM) cooling.
For example, Patent Document 1 presents a battery module that uses air-cooled heat dissipation, which includes disposing heat dissipating members at two or more interfaces between a plurality of plate-type battery cells. Passing air is used as a coolant.
Patent Document 2 includes a battery pack, a heat exchange system, and a temperature control device, and the heat exchange system includes a heat exchanger, a coolant circulation line, and a refrigerant circulation line. Is disclosed. This system uses a coolant instead of air as a medium and employs a heat exchange method to cool or heat the battery.
Furthermore, "Battery and / or capacitor module used for battery cooling" described in Patent Document 3 presents a battery heat dissipation technology that uses a phase change material as a coolant, and basically employs a compressor and a capacitor. In the cooling system, a coolant (for example, ethylene glycol) or a refrigerant (for example, R-11 and R134A) is used as a coolant.

The several prior arts described above basically establish a cooling module outside the battery / capacitor pack. All these technologies focus on improving the cooling structure around the battery and / or capacitor battery / module, or using different materials for the cooling panel or heat dissipation assembly outside the battery / capacitor module. These prior arts also divide the battery / capacitor and the cooling system into two independent parts.
Such a structure in which the battery and the cooling part are separated has a limited cooling effect on the battery. The cause is that a general lithium ion battery is mainly composed of an anode (Anode, for example, graphite), a cathode (Cathode, for example, lithium), an electrolyte, and a separator (Separator), and the electrolyte is usually a liquid in most batteries. In order to prevent the cause of oxidation and moisture, the electrode, electrolyte and necessary separator are packaged in a permanently sealed pack, and the packaging material also reduces heat conduction, This eliminates the opportunity to conduct heat directly.
All of the above-described conventional cooling methods are used to lower the temperature outside the battery module / battery pack.
