Problems solved by technology

[0007] Traditional methods can improve the efficiency of high-voltage batteries, but these methods may complicate the layout of the coolant path, and components are required to distinguish the path of the coolant. In addition, in the complex layout of the coolant path, in order to distinguish the circulation path of the coolant, The number of components may increase and there may be space constraints for the placement of battery coolers and battery heaters on the coolant path

Abstract

The invention relates to a cooling system of an electric vehicle which includes: an integral valve with one or more coolant inlets and two or more coolant outlets, and which selectively discharges coolant through one of the coolant outlets; coolant paths that are connected with each other such that the coolant discharged through one of the coolant outlets is introduced back into the integral valvethrough the one or more coolant inlets after being supplied to a portion where coolant circulation is required; and a temperature controller that selectively controls a temperature of the coolant. The integral valve, at least a portion of the plurality of coolant paths, and the temperature controller may form one valve module.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2019-0023227 filed with the Korean Intellectual Property Office on February 27, 2019, the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates to a cooling system for an electric vehicle, and more particularly, to a cooling system for an electric vehicle capable of improving cooling efficiency of an electric device. Background technique [0004] Generally, an electric vehicle (EV) is equipped with a drive motor, transmission equipment, and power electronics (PE). Here, the term "electric vehicle" is a general name for a vehicle that uses electricity as a power source for the vehicle. [0005] Power electronics include inverters, direct current to direct current (DC-DC) converters, junction boxes, Virtual Engine Sound System (VESS), and chargers. An inverter is a device that converts ...
