Description

Technical Field

[0001] The present invention relates to the technical field of battery packs, and in particular to a temperature-adjustable battery assembly and system. Background Art

[0002] Batteries operating at too high a temperature will accelerate their aging process, thus affecting the performance and life of the battery. Temperature-adjustable battery components and systems monitor the operating temperature of the battery in real time and adjust it to ensure that the battery operates within the optimal temperature range. This can not only slow down the aging of the battery, but also significantly improve the battery life. Secondly, batteries operating at extreme temperatures may cause safety issues such as thermal runaway, spontaneous combustion, and even explosion. Temperature-adjustable battery components and systems can effectively prevent battery overheating by timely monitoring the battery temperature and taking corresponding cooling or heating measures.

One end of the top cover has a first external vent, and the other end has a second external vent. A cooling fan is fixed at the first external vent; and there is liquid in the heat dissipation channel. The heat dissipation mode of the battery of this technology is adjustable, so that the operating temperature of the battery can be adjusted according to different ambient temperatures. However, the battery assembly still has the following problems in use.

[0004] When the battery assembly is temperature-regulated, although temperature sensing can be used and a fan can be used to provide cooling when the set temperature is exceeded, during the cooling process, the air vent position and the cooling liquid position are both fixed contact positions, which makes it difficult to simultaneously perform flow contact cooling on the upper and lower surfaces of each battery cell of the battery assembly, and it is difficult to perform large-area flow cooling on the outside and intervals of each battery cell, resulting in temperature regulation blind spots and poor temperature regulation effects.

[0027] In this technical solution, as shown in the attached Figure 6 -Attached Fig.11 As shown, the internal interval temperature regulating mechanism includes a swing motor 31 fixedly mounted on one side of the battery housing 1; a linkage rod 32 is fixedly connected to the output end of the swing motor 31, and the linkage rod 32 is rotationally connected to the battery housing 1, a sliding frame 33 is fixedly mounted on one side of the outer wall of the linkage rod 32, and a limited sliding shaft 34 is slidably connected to the inner wall of the sliding frame 33 and away from the linkage rod 32, and a rectangular frame tube 35 is fixedly mounted on one end of the limited sliding shaft 34, and the battery housing 1 and the rectangular frame tube 35 are both slidably connected to the sliding frame 33; two rectangular spacer tubes 36 are fixedly connected to one side of the inner wall of the rectangular frame tube 35, and a shunt connecting tube 37 fixedly connected to the rectangular frame tube 35 is provided between the two rectangular spacer tubes 36.

[0028] A connecting hose 38 is fixedly connected to the inner wall of the rectangular frame tube 35 and located at one side of the rectangular spacer tube 36.

The two rectangular spacer tubes 36 are symmetrically arranged about the shunt connecting tube 37, and both the two rectangular spacer tubes 36 are fixedly connected to the shunt connecting tube 37.

[0029] A temperature-adjustable battery system includes a controller 42 fixedly arranged below a swing motor 31, so as to perform temperature sensing on the hot air discharged from a detection tube 24 through a temperature sensor 25. When the temperature value sensed by the temperature sensor 25 is higher than the temperature value set by the controller 42, the electric cylinder 2 is started through the controller 42 to realize the driving operation of the electric cylinder 2.

[0030] The method of using the temperature-adjustable battery assembly of the present invention is as follows: Step 1: When the flow diversion and temperature adjustment are linked, the boost pump 30 is started by the controller 42, and the boost pump 30 delivers external cooling air to the boost pipe 29, and the boost pipe 29 injects the cooling air into the two flow guide pipes 28, and at the same time, the boost pipe 29 injects the cooling air into the boost hose 39, and injects it into the rectangular frame pipe 35 through the boost hose 39, and the rectangular frame pipe 35 is shunted into the two rectangular spacer pipes 36, and the cooling air is injected into the shunt connecting pipe 37. In this way, the rectangular frame pipe 35, the two rectangular spacer pipes 36, and the shunt connecting pipe 37 all cool down the multiple battery cells 40, and then the hot air after heat exchange is delivered to the connecting hose 38, and collected into the output collecting pipe 23 through the connecting hose 38. Then, it is delivered to the injection shunt pipe 27 through the flow guide pipe 28, and the cooling air is shunted into the multiple injection hoses 26 along the injection shunt pipe 27, and the multiple injection hoses 26 are respectively shunted into the multiple rectangular cooling pipes 13.

[0031] After absorbing heat inside the rectangular cooling tube 13, it is transported to the output hose 20, poured into the output rectangular tube 21 through the output hose 20, and collected by the output rectangular tube 21. It is diverted to the inside of the diversion branch pipe 22 along the output rectangular tube 21, and then enters the output collection pipe 23 through the diversion branch pipe 22. After being collected along the output collection pipe 23, it is transported to the detection pipe 24, and discharged through the detection pipe 24. The detection pipe 24 performs the operation of discharging the hot air. At the same time, the temperature of the hot air discharged from the detection pipe 24 is sensed by the temperature sensor 25. When the temperature value sensed by the temperature sensor 25 is higher than the temperature value set by the controller 42, the electric cylinder 2 is started by the controller 42.

[0032] Step 2: During double-sided linkage temperature adjustment, the electric cylinder 2 pushes the sleeve plate 3 to move right, and the sleeve plate 3 moves right along the outer wall of the electric cylinder 2. At the same time, the sleeve plate 3 drives the concave plate 4 to move right, and the concave plate 4 causes the two linkage shafts 5 to move right. At the same time, the two linkage shafts 5 move right along the inner wall of the battery housing 1, and the two linkage shafts 5 respectively drive the two linkage bars 6 to move right, the linkage bars 6 drive the two connecting columns 7 to move right, the connecting column 7 causes the hinge block 8 to move right, the hinge block 8 drives the two hinge shafts 9 to move right, and the two hinge shafts 9 cause the two sleeve rods 10 to move right and push, the sleeve rod 10 drives the support shaft 11 to move backward, and the support shaft 11 drives the sleeve slider 12 to move backward, the sleeve slider 12 moves backward along the outer wall of the slide bar 14, and the sleeve slider 12 moves backward along the inner wall of the guide frame 15. At the same time, the two sleeve sliders 12 respectively drive the distance between the two rectangular cooling tubes 13 to increase. When the rectangular cooling tube 13 moves backward, the sensing block 19 will be driven to move backward synchronously, and the battery housing 1 supports the sleeve bracket 16, and the sleeve bracket 16 supports the distance sensor 18. The distance sensor 18 senses the distance of the sensing block 19, and the sensing block 19 approaches the proximity sensor 17. When the sensing block 19 approaches the proximity sensor 17, the controller 42 drives the electric cylinder 2 to drive the sleeve plate 3 to move left.

[0033] When the sleeve plate 3 moves to the left, the sleeve plate 3 will drive the concave plate 4 to move to the left, and the concave plate 4 makes the two linkage shafts 5 move to the left, and the two linkage shafts 5 respectively drive the two linkage bars 6 to move to the left, and the two linkage bars 6 respectively drive the two connecting columns 7 to move to the left, and the connecting column 7 drives the hinge block 8 to move to the left, and the hinge block 8 drives the two hinge shafts 9 to move to the left. At the same time, the two hinge shafts 9 respectively drive the two sleeve rods 10 to move to the left, and the two sleeve rods 10 respectively drive the two support shafts 11 to approach each other, and the two support shafts 11 respectively drive the two sleeve sliders 12 to approach each other, and the two sleeve sliders 12 respectively drive the two rectangular cooling tubes 13 to approach each other, so that the multiple rectangular cooling tubes 13 at the bottom of the battery cell 40 are displaced and reciprocated, and the multiple rectangular cooling tubes 13 can increase the moving contact area, and at the same time, the multiple rectangular cooling tubes 13 above the battery cell 40 can also be horizontally displaced and reciprocated, so as to achieve non-dead angle displacement temperature adjustment and quickly cool the upper and lower parts of the battery cell 40.

[0034] Step 3: When adjusting the temperature of the internal interval, the controller 42 drives the swing motor 31 to rotate clockwise, the swing motor 31 drives the linkage rod 32 to rotate clockwise, the linkage rod 32 drives the sliding frame 33 to rotate clockwise, and the sliding frame 33 causes the limit sliding shaft 34 to move downward. At the same time, the limit sliding shaft 34 slides on the inner wall of the sliding frame 33, and the limit sliding shaft 34 will drive the rectangular frame tube 35 to move downward, and the rectangular frame tube 35 slides downward along the inner wall of the battery shell 1, so that the rectangular frame tube 35 cools and adjusts the temperature along the outer parts of the multiple battery cells 40. The rectangular frame tube 35 drives the two rectangular spacer tubes 36 to move downward, and the two rectangular spacer tubes 36 cool and adjust the temperature at the intervals of the multiple battery cells 40. At the same time, the rectangular frame tube 35 drives the shunt connecting tube 37 to move downward, and the shunt connecting tube 37 cools and adjusts the temperature along the intervals of the multiple battery cells 40.

[0035] The controller 42 is then used to drive the swing motor 31, which drives the linkage rod 32 to rotate counterclockwise. The linkage rod 32 drives the slide frame 33 to rotate counterclockwise. The slide frame 33 causes the limit sliding shaft 34 to move upward. The limit sliding shaft 34 will drive the rectangular frame tube 35 to move upward. The rectangular frame tube 35 slides upward along the inner wall of the battery shell 1. The rectangular frame tube 35 drives the two rectangular spacer tubes 36 to move upward. The two rectangular spacer tubes 36 cool and regulate the temperature at the intervals of the multiple battery cells 40. As the swing motor 31 continuously rotates back and forth, the two rectangular spacer tubes 36, the rectangular frame tube 35, and the shunt connecting tube 37 can achieve bottom-up reciprocating cooling and temperature regulation, and the temperature regulation contact area is wider to avoid the existence of contact dead corners.

[0036] Step 4: When the temperature control stops, the hot air output from the inside of the detection tube 24 is continuously sensed by the temperature sensor 25. When the temperature sensed by the temperature sensor 25 is the safe temperature set by the controller 42, the swing motor 31 and the electric cylinder 2 are turned off by the controller 42, thereby reducing energy loss.
