The principle of operation of the present invention will now be described as follows: connecting an energy storage power supply with external equipment through a plug, and then starting a battery control management component 4, wherein the battery control management component 4 can transmit electric energy stored by a battery pack 6 to the equipment for use;
when the battery control management component 4 is started, the control main board 20 is synchronously started, the control main board 20 synchronously starts the heat dissipation fan 123, the heat dissipation fan 123 can suck external cold air through the air suction hopper 124, the air is conveyed into the air inlet cavity 8 through the air supply cavity 122 and each air supply pipe 125, then the cold air enters the heat dissipation gap 7 at each battery pack 6 through the air ventilation groove 11 at the air inlet cavity 8, the cold air can take away heat generated during the operation of each battery pack 6, and the air after heat exchange enters the air outlet cavity 9 through the air ventilation groove 11 at each air outlet cavity 9 and is discharged through each air outlet pipe 13;
when air passes through each heat dissipation gap 7, for the battery pack 6 in a normal state, the surface of the battery pack 6 is very flat, the air flow can smoothly and stably pass through the battery pack 6 and be discharged into the air outlet cavity 9, if the surface of the battery pack 6 generates a bulge phenomenon, the bulge of the battery pack 6 can block the air flow passing through the bulge, so the air flow blocked by the bulge can be blown to the side far away from the battery pack 6 at the same side, namely, the blocked air flow can be blown to the baffle 142 at the same side, the air flow can increase the pressure on the corresponding piezoelectric film 144 through the conical hole 143, and under the extrusion action of the blown air flow, the piezoelectric film 144 can generate tiny deformation to the inner side of the groove 141, when the piezoelectric film 144 deforms, the lattice structure in the piezoelectric film will be distorted, the distortion will cause the change of the relative position between the positive and negative charges, so that the charge distribution is not uniform, the unevenly distributed charges will generate an electric field, and a potential difference is formed on the film, the potential difference will cause free charges to move in the conductive material, thereby forming a current, the amplifying circuit board 147 can amplify the current signal generated when the piezoelectric film 144 deforms and transmit the amplified current signal to the control main board 20 after being processed by the signal processor 148, the control main board 20 will be connected to a power supply loop for supplying power to the electromagnetic switch 146, and at this time, the moving contact of the electromagnetic switch 146 is magnetically closed;
the air flow discharged from the air outlet pipe 13 enters the hollow plate 151 and is discharged into the air exhaust hopper 171 inside the heat insulation box 16 through the round hole 153 on the wind shield 152 and the two air exhaust pipes 155, the hot air entering the air exhaust hopper 171 is conveyed into the communicating pipe 173 through each capillary heat exchange pipe 172, then the communicating pipe 173 can introduce the air flow into the machine box 181 and is discharged through the air exhaust holes 182, when the movable contact of the electromagnetic switch 146 is magnetically closed, the first normally open electromagnetic valve 183 inside the air exhaust holes 182 is started, so that the air entering the machine box 181 can not be discharged through the air exhaust holes 182, the air pressure inside the machine box 181 can be continuously increased, under the action of the increased air pressure, the piston plate 191 can be pushed to drive the pressure lever 192 to move until the pressure lever 192 presses the movable contact of the pressure switch 194, when the movable contact of the pressure switch 194 is closed, the main board 20 is controlled to synchronously start the alarm prompt, at the moment, the personnel can know the potential safety hazards of bulge deformation, the energy storage power supply and equipment are required to be disconnected, the work of the energy storage power supply is stopped, and the corresponding potential hazards of the electromagnetic switch 23 can be accurately detected when the electromagnetic switch 146 is closed, and the corresponding maintenance personnel can be accurately indicated to be in time, and the potential hazards of the maintenance can be indicated by the electromagnetic switch 23;
when the hot air passes through each capillary heat exchange tube 172, heat is absorbed and accumulated by the heat accumulation filler 174, and after the control main board 20 is started, the temperature detector 154 is synchronously started, and when the energy storage power supply is charged and discharged at night, the temperature of the area with larger temperature difference between day and night (such as a plateau) is lower, so that after the temperature detector 154 is started, the temperature detected in the initial state is lower, when the temperature is lower than 0 ℃, the temperature detector 154 gives a low-temperature electric signal to the control main board 20, at this time, when the control main board 20 controls the heat dissipation fan 123 to start, the first normally open electromagnetic valve 183 in the exhaust hole 182, the normally closed electromagnetic valve 185 in the reflux heat preservation tube 184 and the second normally open electromagnetic valve 186 in the air suction tube 124 are synchronously started, and therefore, the air flow passing through the inside of the battery pack 6 circulates through the suction end of the air suction tube 124, and therefore, in the initial stage of the starting of the battery pack 6, the circulating cold air flow can be in contact with the filler 174 for heat exchange, and thus the air flow is quickly warmed in the circulating flow process, and thus the temperature of the air flow can be relieved, when the temperature of the battery pack 6 is lower than the temperature of the low-temperature is lower, and the temperature of the battery pack 6 is higher than the temperature of the first normally open electromagnetic valve 185, and the normally open electromagnetic valve 185 is guaranteed, and the air flow is stably influenced by the air flow in the air flow through the air suction tube 124 when the air intake end is controlled, and the air intake air is controlled by the air intake valve 124.
