Abstract
A fuel cell system including a radiator disposed on an electronic part cooling line, the cooling line configured to pass through an electronic part and to circulate a coolant, the radiator being configured to cool the coolant, a coolant pump configured to pump the coolant to circulate the coolant in electronic part cooling line, and a controller configured to determine whether air bubbles are generated, based on a change in a current of the coolant pump while the coolant is circulating and control an air bleeding through the coolant pump.
Claims24
A fuel cell system, comprising:
- a radiator disposed on an electronic part cooling line, the cooling line configured to pass through an electronic part and to circulate a coolant, the radiator being configured to cool the coolant;
- a coolant pump configured to pump the coolant to circulate the coolant in electronic part cooling line;
- and
- a controller configured to:
- determine whether air bubbles are generated, based on a change in a current of the coolant pump while the coolant is circulating;
- and
- control an air bleeding through the coolant pump.
An air bleeding method, the method comprising:
- circulating a coolant, which is cooled by a radiator, along an electronic part cooling line passing through an electronic part;
- determining whether air bubbles are generated, based on change in a current of a coolant pump while the coolant is circulating along the electronic part cooling line;
- and
- controlling an air bleeding through the coolant pump, when the air bubbles are generated.
A processor-implemented method, the method comprising:
- detecting a presence of air bubbles within a coolant system based on a change in a current draw of a coolant pump during a circulation of coolant within the coolant system;
- and
- initiating an air bleeding process through the coolant pump when the presence of air bubbles is detected.
