The lithium-ion battery has an internal material that is flammable and may catch fire or explode if an abnormal situation, such as overcharging or needle penetration, occurs in the lithium-ion battery.
[0003] To solve this problem, a solid-state battery was developed that replaces a solid electrolyte with a polymer electrolyte. By replacing the solid electrolyte with a polymer electrolyte, the solid-state battery can not only achieve chemical stability but also solve problems such as solution leakage and fire.

[0042] Cooling water flows through the electronic component line 40and is accordingly inserted into the electronic component core 41 Accordingly, the cooling water can cool electronic components, which transfer heat to the electronic component core 41 to exchange.
[0043] The vehicle may contain electronic components such as an electronic control unit (ECU), an on-board charger (OBC), and an electric motor. Such electronic components may generate heat while the vehicle is moving. Accordingly, the electronic component core 41 be a concept that includes both a heat dissipation unit that is directly connected to the electronic components, etc., and a heat dissipation unit that is indirectly connected to the electronic components, etc., via a separate cooling water line.
[0044] The radiator 42 , which is exposed to the ambient air to exchange heat with the ambient air, can be used in the electronic component line 40Accordingly, heat can be transferred to the radiator 42 be introduced after it has been recovered.

A fourth valve 32 is also in the refrigerant cooling line 30 included. The fourth valve 32 is mounted at a location where the refrigerant cooling line 30 from the refrigerant line 10 branched off or connected to it. The fourth valve 32 A flow rate ratio between the refrigerant line 10 and the refrigerant cooling line 30 set.
[0048] The air-cooled condenser 31, which is exposed to the ambient air to exchange heat with the ambient air, can be used in the refrigerant cooling line 30 be included.

[0056] In the first mode, in which interior cooling and battery heating are required, the control device may be configured to control the compressor 11 and the first valve 24controlled in such a way that cooling water, which is cooled by refrigerant, the heat in the cooling core 13 for interior air conditioning, in the water-cooled condenser 12 heated, into the high-voltage battery heat exchange module 21 is introduced.
[0057] The first mode may be a condition in which the temperature of ambient air is relatively high, and accordingly, relatively large interior cooling and relatively small battery heating are required.
[0058] In detail, in the first mode the control device 70 the first valve 24 such that the cooling water flowing from the water-cooled condenser 12 into the high-voltage battery heat exchange module 21 is introduced. In addition, the control device 70 the third valve 51 control in such a way that the refrigerant in the refrigerant line 10into the cooling core 13 for interior air conditioning.

[0064] The third mode may be a state in which the ambient air temperature is appropriate, and accordingly, neither interior heating nor interior cooling is required, heating of the high-voltage battery to an appropriate level is required, and cooling of the electronic components is required.
[0065] In the third mode, the control device 70 the first valve 24 such that the cooling water flowing from the water-cooled condenser 12 into the high-voltage battery heat exchange module 21 is introduced.
