[0030] As Figures 1 to 7As shown, the energy storage module temperature control device includes a casing 1 and a controller 7. The casing 1 has a bottom plate 11, and the two ends of the bottom plate 11 are respectively provided with a face plate 12 and a back plate 13. The top ends of the face plate 12 and the back plate 13 are provided with a top plate 14 parallel to the bottom plate 11. The top of the bottom plate 11 is symmetrically provided with two rows of battery cores 6. The battery cores 6 are provided with temperature sensors 8 for detecting the temperature thereof. The two rows of battery cores 6 have a backflow air duct 15 therebetween. The back plate 13 is provided with a fan 3 corresponding to the backflow air duct 15. The outside of the casing 1 is slidably sleeved with a heating flow guide cover 2 in the vertical direction. The heating flow guide cover 2 has an air inlet cover 21 corresponding to the back plate 13. The two ends of the air inlet cover 21 are provided with air return grooves 22 corresponding to the two sides of the casing 1. The air inlet cover 21 is in communication with the air return grooves 22. The air inlet cover 21 is provided with air inlet windows 23 corresponding to the fan 3. The inside of the air return grooves 22 is provided with electric heating wires 24. The top of the casing 1 is provided with a lifting driving mechanism 4 for driving the heating flow guide cover 2 to move up and down. The temperature sensors 8, the fan 3, the electric heating wires 24, and the lifting driving mechanism 4 are connected with the controller 7. In this embodiment, the energy storage module temperature control device has a heat dissipation mode and a temperature rising mode. In the heat dissipation mode, the lifting driving mechanism 4 drives the heating flow guide cover 2 to move upwards, and the two sides of the casing 1 are opened. The fan 3 is started, and the air outside the casing 1 passes through the battery cores 6 from the two sides thereof into the backflow air duct 15, and then is discharged outward from the fan 3, thereby dissipating heat. In the temperature rising mode, the lifting driving mechanism 4 drives the heating flow guide cover 2 to move downwards. The air inlet cover 21 corresponds to the back plate 13, and the air return grooves 22 correspond to the two sides of the casing 1. The fan 3 drives the air in the backflow air duct 15 to flow out from the fan 3 to the air inlet cover 21, and then flows from the air inlet cover 21 to the air return grooves 22. After being heated by the electric heating wires 24 in the air return grooves 22, the air flows back to the backflow air duct 15 through the battery cores 6, thereby continuously heating the battery cores 6. The controller 7 is pre-set with an upper temperature limit value and a lower temperature limit value. The temperature sensors 8 detect the temperature of the battery cores 6. When the detected temperature value is greater than the pre-set upper temperature limit value, the energy storage module temperature control device enters the heat dissipation mode to dissipate heat of the battery cores 6. When the detected temperature value is not greater than the pre-set upper temperature limit value, the fan 3 stops running. When the detected temperature value is less than the pre-set lower temperature limit value, the energy storage module temperature control device enters the temperature rising mode to heat and raise the temperature of the battery cores 6. The temperature of the battery cores can be adjusted according to the actual temperature. When the detected temperature value is not less than the pre-set lower temperature limit value, the electric heating wires 24 stop running, and the fan 3 stops running after running for a period of time, so that the battery cores are in a proper temperature range, thereby ensuring good operation of the energy storage module.

Specifically, the lifting drive component 43 is an electric push rod, a cylinder or a hydraulic cylinder, preferably an electric push rod.

The top frame 42 is fixedly arranged on the top of the guide rods 41. Specifically, four guide rods 41 are evenly arranged on the top plate 14, and the top frame 42 is an "I" shaped plate. The four ends of the top frame 42 are closed and vertically fixedly connected to the top of the four guide rods 41. The heating guide hood 2 is slidably connected to the guide rods 41 through the connecting plate 44.

[0033] In some embodiments, such as Figure 6 and 7 Inside the air intake shroud 21, on the side corresponding to the air intake window 23, there are two symmetrical first guide surfaces 25. The first guide surface 25 is a quarter-circle arc surface. The first guide surface 25 is used to smoothly guide the air discharged by the fan 3 to both ends of the air intake shroud 21.

[0034] In some embodiments, a second guide surface 26 is fixedly provided at both ends inside the air intake hood 21. The second guide surface 26 is a quarter-circular arc surface and is used to smoothly guide the air inside the air intake hood 21 to the air return groove 22.

[0035] In some embodiments, such as Figure 1 and 8 As shown, a heat dissipation component 5 is provided between adjacent battery cells 6. The two sides of the heat dissipation component 5 abut against the sides of the two adjacent battery cells 6 respectively. The heat dissipation component 5 can increase the heat exchange area of ​​the battery cells 6 and improve the heat exchange effect.

[0036] In some embodiments, the heat dissipation assembly 5 has two parallel heat dissipation side plates 51, and a heat dissipation horizontal plate 53 is uniformly arranged between the two heat dissipation side plates 51. The heat dissipation horizontal plate 53 and the heat dissipation side plates 51 are an integral structure.
