Abstract

Disclosed herein is a liquid-cooled cooling-heating system, and methods of using the system, for adjusting the temperature of a battery system and a power electronic component in a vehicle equipped with a high voltage battery comprising: a radiator; a battery heater; a chiller; first and second coolant pumps; first and second three-way valves; a first coolant passage that allows coolant to flow inseries from the first three-way valve through the first coolant pump, the battery heater, the battery and back to the first three-way valve; a second coolant passage that allows coolant to flow in series from the first three-way valve, through the radiator, the second three-way valve, the second coolant pump, the power electric component, and back into the first three-way valve; a third coolant passage that branches from the second coolant passage and allows coolant to flow in series through the second three-way valve, the chiller and into the second coolant passage; and a controller that controls operation of the battery heater, the chiller, the coolant pumps, and the valves.

Description

technical field [0001] The present invention relates to a liquid-cooled cooling and heating system for an environment-friendly vehicle equipped with a high-voltage battery system and a method of using the system, and more particularly to a method for regulating the battery system and power electronic components when the vehicle is driven based on environmental conditions The temperature of the liquid cooling cooling heating system and the use of the system. Background technique [0002] In recent years, environment-friendly vehicles such as hybrid vehicles having both an engine burning fossil fuels and an electric motor as drive sources and vehicles using only electric motors have been researched and introduced to the market as a solution to the depletion of fossil fuels and environmental pollution. One of the solutions to the problem. [0003] Eco-friendly vehicles include batteries that drive electric motors. Generally, batteries for eco-friendly vehicles have been lithi...
