[0033] When the battery of the energy storage system needs to be cooled, the harmonic processor 701 is first used to control the drive board 702 to start the water pump 502. The water pump 502 inputs the coolant from the first liquid inlet pipe 501 and enters the evaporator 8 through the heat pipe. At this time, the coolant in the evaporator 8 absorbs the heat of the coolant to cool the coolant. Then the coolant enters the first liquid outlet pipe 503 through the water pump 502 and is discharged outward. The battery of the energy storage system is cooled by the refrigerated coolant; when the coolant is consumed, the ball valve 505 is opened by rotating, and coolant is added to the first liquid inlet pipe 501 from the discharge pipe 504. When the coolant expands due to overheating, in order to avoid the pipeline from bursting due to excessive hydraulic pressure, the coolant flows into the expansion tank 507. After the coolant cools down and shrinks, the expansion tank 507 pushes the coolant out and transports it back to the first liquid outlet pipe 503; when the evaporator 8 After the refrigerant absorbs more heat, its cooling effect on the coolant will decrease. At this time, the harmonic processor 701 controls the driving board 702 to start the compressor 602 and the electronic expansion valve 606. The refrigerant in the evaporator 8 enters the second liquid outlet pipe 601 through the heat exchange pipe 801, and the refrigerant enters the heat conduction box 603 through the second liquid outlet pipe 601. At this time, the fan 604 is started to blow air to the heat conduction box 603 to cool the refrigerant in the heat conduction box 603. Subsequently, the refrigerant in the heat conduction box 603 enters the heat exchange pipe 801 through the second liquid inlet pipe 605 and flows back to the evaporator 8, continuously cooling the coolant. When the coolant is output from the first liquid outlet pipe 503, if the coolant temperature is too low, the harmonic processor 701 controls the heater 10 to heat the coolant in the first liquid outlet pipe 503 to restore the temperature, so as to prevent the coolant temperature from being too low and damaging the battery.

The stopper 14 can assist the limit frame 13 to slide into the guide frame 11, and the limit frame 13 cooperates with the guide frame 11.

[0035] When the protective cover 4 needs to be fixed on the protective frame 3, the limiting frame 13 is aligned with the guide frame 11 and then the protective cover 4 is pressed downward. At this time, the limiting frame 13 is rotated on the support frame 12 guided by the guide frame 11. At this time, the torsion spring 15 is twisted and deformed by the force. The reaction force of the torsion spring 15 makes the limiting frame 13 buckled on the guide frame 11, thereby fixing the protective cover 4 on the protective frame 3.

[0036] See also Figure 8 and Fig.10 As shown, it also includes a guide sleeve 17 threadedly arranged on the first mounting seat 2, a card slot 16 is provided on the fixing plate 1, and the guide sleeve 17 can be inserted into the card slot 16. A positioning rod 18 is slidably arranged in the guide sleeve 17, and an elastic member 20 is wound around the positioning rod 18.

A groove portion 1801 is provided on the positioning rod 18, and a card ball 19 is rollingly provided on both sides of the guide sleeve 17. The card ball 19 cooperates with the positioning rod 18 and the groove portion 1801 thereon, and an annular groove 1601 is provided in the card slot 16.

[0037] When it is necessary to fix the protective frame 3 on the fixed plate 1, the positioning rod 18 is pressed downward along the guide sleeve 17. At this time, the elastic member 20 is compressed and deformed by the force so that the groove portion 1801 is aligned with the card ball 19, and then the guide sleeve 17 is screwed into the first mounting seat 2 through a thread.

After the guide sleeve 17 is inserted into the card groove 16 and the card ball 19 is aligned with the annular groove 1601, the positioning rod 18 is released. At this time, the elastic member 20 loses the force and returns to its original state, thereby pushing the positioning rod 18 to slide upward along the guide sleeve 17. The groove portion 1801 of the positioning rod 18 is staggered with the card ball 19. The positioning rod 18 pushes the card ball 19 to slide to the outside of the guide sleeve 17 so that the card ball 19 is stuck in the annular groove 1601, so that the guide sleeve 17 is fixed in the card groove 16 of the fixed plate 1, so that the protective frame 3 is fixed on the fixed plate 1.
