Apparatus for controlling temperature of coolant of battery system cooled by water and method thereof

Abstract

The invention relates to an apparatus for controlling temperature of coolant of battery system cooled by water and a method thereof. The apparatus for controlling a temperature of coolant in a water-cooled battery system, includes a heat exchange module including a passage body configured to receive and circulate the coolant from the circulation line, a heat sink disposed outside the passage body, and a thermoelectric element disposed between the heat sink and the passage body; a shaft part separably coupled to the heat exchange module to stack a plurality of heat exchange modules; a frame part separably coupled to the shaft part to close a front surface, a rear surface, an upper surface and a lower surface of the heat exchange module; and a cooling part coupled to one side of the frame part and configured to discharge external air toward the other opened side of the frame part through a gap of the heat sink by at least one cooling fan, wherein the thermoelectric element gives a response to the cooling part and applyes or cuts off power to reduce or increase the temperature of teh coolant of the heat exchange module.

Description

[0001] Cross reference to related applications [0002] This application claims the priority and rights of Korean Patent Application No. 10-2015-0139852 filed on October 5, 2015, the entire disclosure of which is incorporated herein by reference. Technical field [0003] The present invention relates to a device for controlling the temperature of a coolant in a water-cooled battery system and a method thereof, and more particularly, to a device for controlling the temperature of a coolant in a water-cooled battery system, which is independent of the battery Installed in a suitable location to keep the battery at the best operating temperature, thereby providing the best performance of the battery. Background technique [0004] General vehicles use fossil fuels as energy sources, such as gasoline and diesel. Environmentally Friendly Vehicles (EFV) use natural energy as energy sources to protect the environment, such as hydropower, hydrogen energy, and electricity. [0005] In particu...

AI Technical Summary

Problems solved by technology

[0011] As mentioned above, the conventional water-cooled battery system has some problems: its weight is increased due to the installation of many related parts and units, and it is difficult to apply to commercial EFVs due to high manufacturing and installation costs

[0012] Also, the conventional water-cooled battery system has another problem: it needs to be manufactured separately according to the type of vehicle

[0013] Also, in conventional water-cooled battery systems, it is difficult to perform comprehensive thermal management since the wire heaters and coolers or radiators should be installed separately and then connected to each other

[0014] In particular, in the conventional water-cooled battery system, since the battery pack equipped with a plurality of batteries is installed at the lower part of the vehicle, and the radiator is installed at the front side of the vehicle, or the cooler is installed at the engine room adjacent to the radiator or separate space, so there is the problem that the coolant line should run long from the water cooled battery system to each unit
