Problems solved by technology

[0009] However, in the general U-shaped battery 10 of the above-mentioned structure, the temperature deviation among the battery cells 20 is large, and thus the lifetime of the battery cells 20 is greatly different from each other.
Also, when a part of the battery cells included in the battery is exhausted, the entire battery needs to be replaced, so there is a problem that the unused battery cells cannot continue to be used due to the exhausted battery cells.

Embodiment Construction

[0027] Hereinafter, preferred embodiments of the U-shaped battery for electric vehicles of the present invention will be described in detail with reference to the accompanying drawings.

[0028] image 3 It is a cross-sectional view showing an example of a U-shaped battery for an electric vehicle according to the present invention.

[0029] The U-shaped battery 100 of the present invention includes: a plurality of battery cells 110 ; a first cooling channel 130 coupled to one end of the battery cells 110 ; a second cooling channel 150 coupled to the other end of the battery cells 110 .

[0030] The battery unit 110 is a plate-shaped battery unit, and a plurality of battery units 110 are arranged in series, and the number of columns of the battery unit 110 can be one or more. The voltage charged to the battery unit 110 is used to drive the electric vehicle, and the battery unit 110 is recharged after being discharged. As described above, the battery cell 110 is repeatedly cha...

Abstract

According to the present invention, the life of the battery pack is extended by keeping the temperature variance between the cells low. The battery design is simplified by quantitatively calculating the ratio between the outlet area and the inlet area of the cooling duct by means of a mathematical equation.

Description

technical field [0001] The present invention relates to a battery for an electric vehicle, and more particularly to a U-type battery having cooling passages for allowing refrigerant to flow in and out in opposite directions. Background technique [0002] An electric vehicle is a vehicle that derives its driving energy from electricity, rather than from the burning of fossil fuels like existing vehicles. Electric cars have the advantage of having no exhaust at all and very little noise, but they have yet to be put into practical use due to issues such as heavy batteries and long charging times. However, with the seriousness of pollution problems and the depletion of fossil fuels becoming an important issue, the development of electric vehicles has been accelerated again. In particular, in order to put an electric vehicle into practical use, it is necessary to reduce the weight and size of a battery as an energy source of the electric vehicle, and to shorten the charging time...
