Abstract
A battery cooling system for a vehicle and a method are disclosed. In particular, the battery cooling system may include: a battery cooling apparatus to selectively connected to a cooling apparatus and cool a battery by coolant flowing through the battery cooling apparatus; a battery management system to measure a temperature of the battery in a periodic time interval after a vehicle is turned off; and a controller to control the battery cooling apparatus to cool the battery when the temperature of the batter is higher than a threshold temperature.
Claims4
A battery cooling system comprising:
- a battery cooling apparatus configured to:
- selectively connected to a cooling apparatus, and
- cool a battery by coolant flowing through the battery cooling apparatus;
- a battery management system configured to measure a temperature of the battery in a periodic time interval after a vehicle is turned off;
- and
- a controller configured to cool the battery through the battery cooling apparatus when the temperature of the batter is higher than a threshold temperature,
- wherein:
- the battery cooling apparatus includes:
- a battery cooling line in which the coolant flows;
- a chiller provided on the battery cooling line and configured to heat-exchange with the coolant selectively flowing therein so as to adjust a temperature of the coolant;
- a first valve configured to selectively connect a cooling line of the cooling apparatus to the battery cooling line between a radiator and the battery;
- a branch line connecting the chiller and the battery through the first valve;
- and
- an electric water pump provided on the battery cooling line, and configured to pump the coolant flowing through the battery cooling line, and
- wherein:
- when the temperature of the battery is higher than the threshold temperature,
- the controller is configured to:
- operate the first valve to connect a battery connecting line and the branch line,
- close the cooling line and the battery connecting line, and
- operate the chiller and the electric water pump.
A cooling method for a vehicle, the cooling method comprising:
- measuring, by a battery management system, a temperature of a battery in a periodic time interval;
- and
- cooling, by a controller, the battery through a battery cooling apparatus selectively connected to a cooling apparatus when the temperature of the battery measured by the battery management system is higher than a threshold temperature,
- wherein:
- when the temperature of the battery is higher than the threshold temperature,
- connecting, by a valve controlled by the controller, a branch line and a battery connecting line of the battery cooling apparatus, where the branch line connects a chiller of the battery cooling apparatus and the battery,
- closing, by the valve, a battery cooling line of the battery cooling apparatus and a cooling line of the cooling apparatus, and
- operating the chiller to cool the battery.
