[0025] The utility model magnetically connects the valve cover 2 and the push rod of the electric push rod 3 through the magnetic block 12 and the magnet 13. When the internal and external pressure difference reaches 6±2kpa, the internal air pressure can offset the magnetic force to push open the valve cover 2, thereby realizing the passive valve opening and pressure relief function. This function is integrated with the electric control exhaust valve through a mechanical connection, and the overall structure is simple, the occupied area is small, the cost is low, the risk is reduced, and the difficulty of designing supporting solutions for customers is relatively low.

[0026] Preferably, a fan 4 is installed on one side of the valve plate 1 on which the electric push rod 3 is installed, and the fan 4 is connected to the valve plate 1 through a plurality of support columns 7; specifically, by setting the fan 4, when thick smoke is generated in the energy storage cabinet or the battery pack and the valve cover 2 is opened, the fan 4 runs to quickly discharge the thick smoke inside.

[0027] Preferably, a plurality of guide slide columns 5 are provided on the side of the valve cover 2 facing the valve plate 1, and a plurality of sliding holes 14 are provided on the valve plate 1. The plurality of guide slide columns 5 respectively pass through the plurality of guide slide holes and are connected with anti-detachment blocks 6, so that a sliding connection between the valve cover 2 and the valve plate 1 is realized through the guide slide columns 5 and the sliding holes 14, and the anti-detachment blocks 6 can limit the sliding of the valve cover 2 to prevent the valve cover 2 from being completely separated from the valve plate 1.

[0028] Preferably, the electric push rod 3 is connected and installed with the valve plate 1 through a mounting plate, the mounting plate and the valve plate 1 are fixedly connected by bolts, and the electric push rod 3 is then installed on the mounting plate by bolts, thereby achieving a fixed connection between the electric push rod 3 and the valve plate 1.

[0033] An exhaust method for an electronically controlled exhaust valve comprises the following contents:

[0034] S1. When the box is in a normal state, the valve cover 2 is in a closed state, sealing the exhaust hole 10 to achieve a protective and airtight effect. Figure 4 As shown;

[0035] S2.1. When an abnormality is detected in the box, the internal electronic sensor will feedback a signal, the power supply is energized, the push rod of the electric push rod 3 is controlled to be pushed out, the valve cover 2 is driven to open, the exhaust hole 10 is opened, and the inside of the box is connected with the outside. At the same time, the fan 4 is started, and the internal gas and smoke are rapidly discharged through the exhaust hole 10 to prevent thermal runaway and further deterioration. Figure 5 As shown;

[0036] S2.2, after the valve cover 2 is opened, when the gas and smoke in the box are emptied or further deteriorated, the internal electronic sensor sends a second signal to retract the push rod of the electric push rod 3, drive the valve cover 2 to close, seal the exhaust hole 10, and return the entire electric control exhaust valve to the normal closed state, such as Figure 4 As shown;

[0037] S2.3, when thermal runaway occurs and the motor fails, and the internal and external pressure difference meets 6±2kpa, under the action of the internal and external pressure difference, the air pressure inside the box offsets the magnetic force of the magnetic block 12 on the valve cover 2 and the magnetic control on the push rod, pushes the valve cover 2 out, opens the exhaust hole 10, and realizes passive pressure relief, such as Figure 6 shown.
