Thermal conductive fillers are installed between the upper battery pack and the upper mounting plate, the lower battery pack and the lower mounting plate, the lower mounting plate and the inner bottom surface of the battery box shell, and the radiator and the outer bottom surface of the battery box shell.

[0047] Step S2, five seconds after the processing module detects the high temperature state, the processing module controls the liquid cooling component to start, and compares the appropriate temperature data in the battery housing in real time during the startup of the liquid cooling component, until the processing module detects the appropriate temperature state or the low temperature state. Five seconds after the processing module detects the low temperature state, the processing module controls the liquid cooling component to close, and compares the appropriate temperature data in the battery housing in real time during the liquid cooling component closing, until the processing module detects the appropriate temperature state or the high temperature state. Five seconds after the processing module detects the appropriate temperature state, the processing module controls the liquid cooling component to save the current state, and compares the appropriate temperature data in the battery housing in real time during the liquid cooling component closing, until the processing module detects the low temperature state or the high temperature state, thereby realizing the function of accurately controlling the temperature in the liquid-cooled battery housing to reduce energy waste;

[0050] Working principle: the function of the limit plate 11 is to provide support for the motor 13. The liquid in the buffer box 2 enters the infusion tube 4, and enters the liquid flow area 5 through the infusion tube 4 to cool down the hollow open area 6. At this time, the rotation of the motor 13 drives the striking head 14 to rotate, and the rotation of the striking head 14 drives the moving plate 10 to move. The movement of the moving plate 10 drives the pulley 9 to move. The movement of the pulley 9 causes the moving plate 10 to drive the No. 1 spring 12 to move.

The movement of the moving plate 10 moves the cold air in the hollow open area 6 through the through-hole 37 to the battery surface to quickly cool it down, thereby realizing the rapid cooling of the battery by the liquid-cooled battery shell. The function of improving the cooling effect is that the processing module controls the liquid cooling component to start five seconds after it detects the high temperature state, and compares the appropriate temperature data in the battery housing in real time during the startup of the liquid cooling component until the processing module detects the appropriate temperature state or the low temperature state. The processing module controls the liquid cooling component to shut down five seconds after it detects the low temperature state, and compares the appropriate temperature data in the battery housing in real time during the shutdown of the liquid cooling component, until the processing module detects the appropriate temperature state or the high temperature state. The processing module controls the liquid cooling component to save the current state five seconds after it detects the appropriate temperature state, and compares the appropriate temperature data in the battery housing in real time during the shutdown of the liquid cooling component, until the processing module detects the temperature.

The plug has the function of facilitating cleaning. When the shell 1 is impacted, the rubber pad 21 moves. The movement of the rubber pad 21 drives the shell 1 to move. The movement of the shell 1 drives the No. 1 damping block 16 to move. The movement of the No. 1 damping block 16 reduces the impact force.
