Battery heat management integration system and operation method thereof
A battery heat management integration system is provided. The system includes a battery cooler that connects a battery in which battery cooling water is circulated and an air conditioning system in which air conditioner refrigerant is circulated. A heat exchange effect thus occurs between the battery cooling water and the air conditioner refrigerant.
1. A battery heat management integration system, comprising:
a battery cooler that connects a battery in which battery cooling water is circulated and an air conditioning system in which air conditioner refrigerant is circulated, and causing the heat exchange effect between the battery cooling water and the air conditioner refrigerant;
a battery cooling line in which the battery cooling water is circulated;
an air conditioning cooling line in which the air conditioner refrigerant is circulated;
a cooler connection line connected with a first cooler inlet line of the battery cooling line;
a discharge line connected from the battery to the cooler connection line connected with the first cooler inlet line, a via line connected to the discharge line to pass through a radiator, and a return line connected to the via line to be connected to the battery; and
a radiator path valve provided at a connection part of the cooler connection line and the discharge line, a battery cooler path valve provided at a connection part of the cooler connection line, the return line, and the first cooler inlet line.
2. The battery heat management integration system of claim 1 , wherein the battery cooling line and the air conditioning cooling line separate the flow of the battery cooling water and the air conditioner refrigerant.
3. The battery heat management integration system of claim 1 , wherein the battery cooling line includes the first cooler inlet line for discharging the battery cooling water coming from the battery into the battery cooler, and a first cooler outlet line for returning the battery cooling water coming from the battery cooler to the battery; and the air conditioning cooling line includes a second cooler inlet line for discharging the air conditioner refrigerant coming from the air conditioning system into the battery cooler, and a second cooler outlet line for returning the air conditioner refrigerant coming from the battery cooler to the air conditioning system.
4. The battery heat management integration system of claim 1 , wherein the radiator path valve and the battery cooler path valve are operated by a battery management system (BMS) to change the direction of a flow path.
5. The battery heat management integration system of claim 4 , wherein the BMS is configured to operate a cooling fan, a cooling water pump, and an electric heater, wherein the cooling fan is provided on the radiator, the cooling water pump is provided on the discharge line, and the electric heater is provided on the return line.
6. The battery heat management integration system of claim 4 , wherein the BMS is connected with a temperature sensor and the temperature sensor includes a battery temperature sensor configured to detect the temperature of the battery, a battery cooling water temperature sensor configured to detect the temperature of the battery cooling water, and an atmospheric temperature sensor configured to detect as the ambient temperature.
7. The battery heat management integration system of claim 4 , wherein the BMS is connected with an air conditioning control panel for executing an operation mode of the air conditioning system, and the BMS is in communication with the air conditioning control panel to perform the heat exchange operation of the battery cooler in a chiller mode.
8. The battery heat management integration system of claim 7 , wherein the BMS is configured to transmit a battery temperature proportional value of the battery to the air conditioning control panel in the chiller mode.
