Description

[0001] The invention relates to a vehicle thermal management system, and more particularly to a vehicle thermal management system that varies the cooling area of ​​a high-voltage battery core and an electrical component core based on the condition of the vehicle.

[0002] Recently, electric vehicles have been developed to implement environmentally friendly technologies and solve the problem of energy depletion. An electric vehicle operates using an engine (e.g., an electric motor) that absorbs electrical current supplied by a battery and outputs power. Therefore, there is no carbon dioxide emission, minimal noise, and the energy efficiency of the electric motor is higher than that of an internal combustion engine, making the electric vehicle recognized as an environmentally friendly vehicle.

[0003] The key technology for realizing such an electric vehicle is the technology related to the battery module. Recently, research has been actively conducted into battery weight reduction, miniaturization, and reduced charging time. The battery module can achieve optimal performance and a long service life when used in an optimal temperature environment. However, using the battery in the optimal temperature environment may be difficult due to the heat generated during driving and changes in external temperature.

[0004] Furthermore, since the electric vehicle lacks a waste heat source for the heat generated during combustion in an engine such as an internal combustion engine, it is necessary to perform interior heating of the vehicle using an electric heater in winter or colder temperatures and to perform warm-up to improve the charging and discharging performance of the battery during a cold period. Therefore, an electric heater is separately configured and used to heat the cooling water. In other words, to maintain the optimal temperature environment of the battery module, a cooling and heating system for adjusting the temperature of the battery module is used separately from a cooling and heating system for an interior HVAC (heating, ventilation, and air conditioning) of the vehicle.Two independent cooling and heating systems are formed, one of which is used for cooling and heating the interior, and the other is used for temperature control of the battery module.

In the radiator module, the battery radiator and the electrical component radiator may be stacked or layered in the thickness direction.

[0008] The passages in the first chamber and the passages in the second chamber may be connected to a cooling water inlet side and a cooling water outlet side of components connected thereto, respectively, to cause the cooling water to circulate through the components and the battery radiator or the electrical component radiator. The high-voltage battery core may be arranged between the second passage in the first chamber and the second passage in the second chamber in such a way that it is connected in series with a first pump. A battery heat exchange line may be arranged between the second passage in the first chamber and the second passage in the second chamber in such a way that it is connected in parallel with the high-voltage battery core and the first pump and passes through a water heater and a battery cooler (or a battery cooling system or a battery cooling unit).The battery heat exchange line may be configured such that a flow of cooling water is adjusted by a switching valve (or on-off valve).

[0010] The vehicle thermal management system may further include a controller configured to operate the actuator to close the second passages in the first chamber and the second chamber, open the switching valve, and drive the first pump and the second pump when electrical component cooling and battery coolant cooling are required. The vehicle thermal management system may further include a controller configured to operate the actuator to close the first passages in the first chamber and the second chamber, close the switching valve, and operate the first pump or the second pump when electrical component waste heat recovery is required.

[0011] The vehicle thermal management system may further include a controller configured to operate the actuator to close the second passages in the first chamber and the second chamber and operate the second pump when electrical component cooling is required. The vehicle thermal management system may further include a controller configured to operate the actuator to close the third (or second) passages in the first chamber and the second chamber, close the switching valve, and operate the first pump and the second pump when electrical component cooling and battery cooling are required.
