[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0035] For example, see Figure 1-7 , the present invention provides a technical solution: a multi-storage position aging test device, comprising a base 1, a testing mechanism 2 is fixedly connected to the top of the base 1, and a U-shaped bin 3 is fixedly connected to the outer wall of the base 1;

[0036] Place the battery pack to be tested into the test chamber 23, and then close the door panel 24;

[0037] Test organization 2 includes:

[0038] The motor 22 is fixedly connected to the top of the base 1;

[0039] A test chamber 23, the test chamber 23 is rotatably connected to the bottom of the motor 22, and the outer wall of the test chamber 23 is rotatably connected to the door panel 24;

[0040] A flow component 25, the flow component 25 is fixedly connected to the outer wall of the test chamber 23;

[0041] The moving assembly 26 is fixedly connected to the outer wall of the U-shaped bin 3 .

[0042] The motor 22 is fixedly connected to the top of the base 1 through the first bracket 21 .

[0043] The flow assembly 25 includes air flow holes 253 . The air flow holes 253 are opened at the top and the bottom of the test chamber 23 .

[0044] The moving assembly 26 includes a slide rail 262 , which is fixedly connected to the outer wall of the U-shaped bin 3 , and an electric slider 261 is slidably connected to the outer wall of the slide rail 262 .

[0045] The slide rail 262 is fixedly connected to the outer wall of the U-shaped bin 3 via a second bracket 263 , and the outer wall of the electric slider 261 is fixedly connected to a third bracket 264 .

[0046] The outer wall of the third bracket 264 is fixedly connected with a heater 252, the top of the heater 252 is fixedly connected with a fan 251, the outer wall of the U-shaped bin 3 is provided with a hole at the position of the heater 252, the outer wall of the U-shaped bin 3 is fixedly connected with an elastic band 4 at the position of the hole, and the heater 252 is plugged into the outer wall of the elastic band 4;

[0047] The heater 252 is powered on to generate heat. The heater 252 generates heat by heating the water flow and then generates heat by flowing. The fan 251 is powered on to fan the air flow. The air flow carries the heat generated by the heater 252 and blows onto the battery pack in the test chamber 23 through the air flow hole 253. Then, the air flow is discharged from the air flow hole 253 at the top of the test chamber 23.

[0048] The heater 252 can also be connected to other wastewater discharged with heat, and then pass through the heater 252 to generate heat;

[0049] The slide rail 262 is in an arc shape. The electric slider 261 is powered on and moves on the slide rail 262. When the electric slider 261 moves, it drives the heater 252 and the fan 251 to move, thereby changing the exhaust direction of the airflow, so that different positions heat up the test chamber 23, and then heat up the battery pack inside it at multiple angles.

[0050] The elastic band 4 is made of elastic material and will produce elastic deformation when the heater 252 moves.

[0051] For example 2, please refer to Figure 1-8Based on the first embodiment, the present invention provides a technical solution:

[0052] The outer wall of the test chamber 23 is fixedly connected with the electromagnetic mechanism 5 , and the outer wall of the test chamber 23 is provided with a groove adapted to the size of the electromagnetic mechanism 5 .

[0053] The electromagnetic mechanism 5 includes a telescopic machine 55, which is fixedly connected in the groove of the test chamber 23. The top of the telescopic machine 55 is movably connected with a coil 53. The top of the coil 53 is fixedly connected to the inner wall of the groove of the test chamber 23 through a fixing ring 54. The outer wall of the test chamber 23 is fixedly connected with an energizing component 51. The energizing component 51 is fixedly connected to the two ends of the coil 53 through two energizing rods 52.

[0054] The electromagnetic mechanism 5 is arranged in a groove on the side of the test chamber 23. The energizing component 51 connects the two ends of the coil 53 through the energizing rod 52. At this time, the coil 53, the energizing component 51 and the energizing rod 52 are in a short-circuit state, thereby generating heat, which heats the test chamber 23 through the side thereof;

[0055] Moreover, when the coil 53 is energized, the current is formed by the directional movement of charges. According to electromagnetic theory, the moving charges will generate a magnetic field in the space around them. In the coil 53, when current passes through, the free electrons move in a directional manner in the wire, and these moving electrons will generate a magnetic field around them. The magnetic fields generated by the movement of many electrons are superimposed to form a macroscopic magnetic field exhibited by the coil 53. Iron filings are added to the U-shaped bin 3 in advance. The U-shaped bin 3 is set in an arc shape, so the iron filings in the U-shaped bin 3 will fall to the bottom of the heater 252. The heat generated by the heater 252 is transferred to the iron filings. Then, when the electric slider 261 drives the heater 252 to move, the heater 252 will squeeze the iron filings in the U-shaped bin 3 to follow the movement. At this time, there is no interval of the heater 252. The telescopic machine 55 is started to drive the bottom of the coil 53 to rise. When rising, the line spacing is reduced, which increases the magnetic field strength. The magnetism generated by the coil 53 will adsorb the iron filings, and then the generated heat is transferred to the test bin 23.

[0056] When the telescopic machine 55 is started for an intermittent period, the energized rod 52 and the coil 53 have a certain elasticity. Subsequently, the telescopic machine 55 will pull the coil 53 down to reset. At this time, the weakening of the magnetism will make it impossible for the magnetism to firmly adsorb the iron filings, and the iron filings will fall along the arc of the U-shaped bin 3 again.

[0057] According to the Biot-Savart law, the magnitude of the magnetic induction intensity generated by the current element at a point in space is proportional to the magnitude of the current element, proportional to the sine of the angle between the current element and the radius vector from the current element to the point, and inversely proportional to the square of the radius vector. The reduction in the line spacing of coil 53 means that the number of turns of coil 53 per unit length increases. Under the condition of unchanged current, according to Ampere's loop theorem, the magnetic field inside the infinitely long straight solenoid can be derived. It can be seen that the magnetic field strength is proportional to, so the reduction in line spacing will increase the magnetic field strength.

[0058] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
