Description

Technical Field

[0001] The present invention mainly relates to the technical field of new energy batteries, and specifically to a new energy battery with high protection. Background Art

[0002] New energy batteries are an advanced battery technology used in electric vehicles, energy storage systems and renewable energy fields. They aim to improve energy efficiency, reduce dependence on fossil fuels and reduce greenhouse gas emissions. These batteries are mainly divided into lithium-ion batteries, sodium-ion batteries, lithium-sulfur batteries, solid-state batteries and other types. When new energy batteries are used in electric vehicles, they need to have a highly protective structure to ensure driving safety.

[0003] At present, the protective new energy batteries in the prior art are mostly devoted to the research on shock absorption, buffering, heat dissipation and temperature reduction. For example, a heat dissipation and shock-resistant new energy vehicle battery protection box is disclosed in the patent with the authorization publication number CN 113675525 A. During the application process, when vibration occurs, the support member will shake, and the elastic member connected to the support member can play a role of buffering and reducing pressure on the support member; when the temperature in the shell rises, the driving component drives the fan blades installed in the shell to rotate through the first transmission component and can also realize reciprocating movement, thereby dissipating heat and cooling the shell. At the same time, the driving component drives the cleaning brush to reciprocate through the second transmission component, so that the cleaning brush cleans the dust on the surface of the battery.

[0004] A patent with application publication number CN 112133981 A discloses a heat dissipation protection auxiliary device for a lithium battery assembly of a new energy vehicle. When the vehicle moves normally, the fixed frame shakes on the base, and the shaking force cooperates with the support rod and the connecting bolt to transmit the force to the movable rod. The movable rod squeezes the first airbag and the second airbag, so that the air intake and exhaust of the first airbag can be realized, achieving the effect of shock absorption and buffering. At the same time, with the function of the connecting pipe, the liquid inside the water cooling pipe can be moved, and the liquid moved inside the water cooling pipe cools the battery body, thereby achieving the effect of stable cooling.

[0005] However, the protective new energy batteries in the prior art have the following problems: First, in cold climates, the activity of the chemical materials in the battery will also decrease, and the number of materials involved in the chemical reaction will decrease, which will lead to a decrease in the battery's storage capacity. Second, in the event of overheating, overcharging or other abnormal conditions, the battery has the potential safety hazard of fire or explosion. That is, the existing protective new energy batteries lack corresponding protective structures to avoid or alleviate problems in cold and / or overheating, overcharging and the like.

[0037] The water tank assembly 9 includes a water tank body 901, in which coolant is filled, and a heating tube 902 for heating the coolant is installed in the water tank body 901; the heating and cooling assembly 3 is used to cool / heat the battery assembly 10, and the coolant cooling assembly is used to cool the hot coolant discharged from the heating and cooling assembly 3 when the battery assembly 10 needs to be cooled.

[0038] Specifically, Figures 1 to 4As shown, the outer frame assembly 1 includes an outer frame 101, a connecting member 102, a buffer pad 103, a hydraulic spring buffer 104 and a slide groove 105, and the outer frame 101 includes a plane frame located at the front and rear ends and a three-dimensional frame located in the middle, wherein two opposite sides of the three-dimensional frame in the middle and four vertex corners of the outer sides of the plane frames at the front and rear ends are fixedly connected with connecting members 102 for connecting to the car, and the outer side of the horizontal part of the connecting member 102 is fixedly connected with the buffer pad 103; the hydraulic spring buffers 104 are fixedly connected on the opposite sides of the plane frames at the front and rear ends; and the slide groove 105 is provided on the inner side of the three-dimensional frame in the middle. The advantage is that during installation, the internal components of the inner frame assembly 2 are fixedly connected, and the outer frame assembly 1 is installed on the car body by bolts through the connecting piece 102. The front end of the outer frame assembly 1 is in the same direction as the front of the car, and the buffer pad 103 provides longitudinal buffering for the outer frame assembly 1; and the slide groove 105 facilitates the sliding connection of the inner frame assembly 2, and cooperates with the function of the hydraulic spring buffer 104 to provide buffering in the front and rear directions for the inner frame assembly 2 and its internal components.

[0039] Specifically, Figure 4 As shown, the inner frame assembly 2 includes an inner frame 201 and a slide bar 202. The outer sides of the four sides of the inner frame 201 are fixedly connected with the slide bars 202. The slide bars 202 are slidably connected with the slide grooves 105 in a one-to-one correspondence. The hydraulic spring buffer 104 is slidably connected with the inner frame 201. The advantage is that when the car is hit, the inner frame assembly 2 and its internal components move forward and backward under the action of inertia, triggering the hydraulic spring buffer 104 on the corresponding side to reduce the external impact force, which is conducive to maintaining the stability of the battery assembly 10. The outer frame assembly 1 and the inner frame assembly 2 provide protection for the battery assembly 10.

[0040] Specifically, Figure 6As shown, the heating and cooling component 3 includes a square shell 301, a heat conductive sheet 302, a motor 303, a flap 304, a water pump 305, a copper tube 306, a three-way solenoid valve 307 and a return pipe 308. The square shell 301 is attached to the battery assembly 10, and the inside of the square shell 301 is fixedly connected with the heat conductive sheet 302. The front end of the heat conductive sheet 302 is provided with a flap 304, and one side of the flap 304 is connected to a motor 303 for driving the flap 304 to deflect. The area where the heat conductive sheet 302 is located is provided with a circuitous copper tube 306, the input end of the copper tube 306 is connected to the water pump 305, and the water pump 305 is connected to the water tank assembly 9, the output end of the copper tube 306 is connected to the input end of the three-way solenoid valve 307, one of the output ends of the three-way solenoid valve 307 is connected to the input end of the return pipe 308, and the output end of the return pipe 308 is connected to the water tank assembly 9. The advantage is that a heating and cooling component 3 is provided, which cooperates with the water tank component 9 to cool or heat the battery component 10, and provides a stable and suitable working temperature for the battery body 1002. The short side width of the flap 304 is equal to the internal height of the square frame housing 301. The advantage is that the flap 304 and the motor 303 are provided, and by switching the vertical state and the horizontal state of the flap 304, it can be controlled whether to start natural air cooling.

[0041] Specifically, Figures 5 to 8 As shown, the coolant cooling component includes a side plate 4, a vent 5, a heat sink 6, and a cooling pipe 7. Two side plates 4 are provided, and a vent 5 is opened on the side plate 4. The heat sink 6 is fixedly connected between the two side plates 4. The cooling pipe 7 is arranged in a circuitous manner in the area where the heat sink 6 is located. The input end of the cooling pipe 7 is connected to the other output end of the three-way solenoid valve 307 in the heating and cooling component 3, and the output end of the cooling pipe 7 is connected to the water tank component 9. The advantage is that when the heating and cooling component 3 performs heat dissipation and cooling on the battery component 10, the temperature of the coolant increases after heat exchange, and the coolant discharged from the copper tube 306 first passes into the cooling pipe 7, and after cooling through the heat sink 6 and the vent 5, it is sent back to the water tank component 9 to avoid affecting the subsequent cooling effect.

[0042] Specifically, Figure 7 and Figure 8As shown, the water tank assembly 9 includes a water tank body 901, a heating pipe 902, a water pump 2 903 and a connecting pipe 904. The water tank body 901 is filled with coolant, the water tank body 901 is connected with a heating pipe 902, the two sides of the water tank body 901 are fixedly connected with the water pump 2 903 through pipelines, the output end of the water pump 2 903 is fixedly connected with a connecting pipe 904, and the output end of the connecting pipe 904 is connected to the battery assembly 10. The advantage is that the runaway temperature of the new energy battery refers to the temperature threshold that may cause the battery to run away and cause fire or explosion when the battery is overheated, overcharged or in other abnormal conditions. At this time, the water pump 2 903 is started to pump out the coolant in the water tank body 901, and is injected into the battery shell 1001 through the connecting pipe 904. The coolant surrounds the two sides of the battery body 1002, forcing the battery body 1002 to cool down, and buying time for the occupants to escape. The right side of the water tank assembly 9 is fixedly connected with a controller 12 and a temperature sensor 13. The sensing end of the temperature sensor 13 extends into the battery shell 1001. The controller 12 is electrically connected to the temperature sensor 13, the heating and cooling assembly 13, and the water tank assembly 9. The temperature sensor 13 senses the temperature inside the battery shell 1001 in real time and sends the data to the controller 12. The controller 12 is electrically connected to the vehicle main control panel. The controller 12 presets the battery's suitable operating temperature range, such as 0°C to 40°C, and presets the out-of-control temperature.

[0043] Specifically, Figure 8 As shown, the battery assembly 10 includes a battery shell 1001 and a battery body 1002. The battery body 1002 is disposed inside the battery shell 1001, and the upper and lower ends of the battery body 1002 are in contact with the battery shell 1001. The output end of the connecting tube 904 extends into the battery shell 1001 to facilitate the input of the coolant into the battery shell 1001 to contact the battery body 1002.

[0044] Specifically, the battery shell 1001 and the frame shell 301 are both made of pure aluminum alloy, which has high thermal conductivity, and is conducive to optimizing the heat exchange effect between the heating and cooling components and the battery body 1002.

[0045] Specifically, the front and rear of the frame shell 301 are through-structured to facilitate air cooling.

[0046] Embodiment 2: As an improvement to the previous embodiment.

[0047] In this embodiment, if Figure 5 to Figure 6As shown, a heating and cooling component 11 is also provided in the inner frame component 2. The structure and function of the heating and cooling component 11 are the same as those of the heating and cooling component 13, and the two sets of heating and cooling components are clamped on the upper and lower sides of the battery component 10; the coolant cooling component is also provided with a cooling pipe 8, which is arranged in a circuitous manner in the area where the heat sink 6 is located, and the input end of the cooling pipe 8 is connected to the other output end of the three-way solenoid valve 307 in the heating and cooling component 11, and the output end of the cooling pipe 8 extends into the interior of the water tank body 901.

[0048] In this embodiment, if Figure 8 As shown, the battery assembly 10 further includes a buffer block 1003, and the buffer blocks 1003 are fixedly connected to both sides of the battery body 1002, and the buffer blocks 1003 are made of fluororubber. The advantage is that the buffer block 1003 made of fluororubber is provided, which is resistant to high temperature and chemical corrosion, and provides buffer protection for both sides of the battery body 1002.

[0049] Specifically, the sensing end of the temperature sensor 13 extends into the battery shell 1001, and the controller 12 is electrically connected to the temperature sensor 13, the heating and cooling component 1 3 and the heating and cooling component 2 11, and the water tank component 9.

[0050] Working principle: When in use, first fix the battery assembly 10, the water tank assembly 9, and the coolant cooling assembly between the heating and cooling assembly 1 3 and the heating and cooling assembly 2 11, then fix the inner frame assembly 2 with the heating and cooling assembly 1 3 and the heating and cooling assembly 2 11, and then slide the inner frame assembly 2 into the outer frame assembly 1, and finally install the connecting piece 102 of the outer frame assembly 1 on the car body with bolts, and the front end of the outer frame assembly 1 is in the same direction as the front of the car.

[0051] (1) Shock absorption and buffering protection: The buffer pad 103 provides longitudinal buffering for the outer frame assembly 1. When the car is hit, the heating and cooling assembly 1 3, the water tank assembly 9, the heating and cooling assembly 2 11 and the inner frame assembly 2 move forward under the action of inertia. The inner frame assembly 2 moves forward along the slide groove 105. The hydraulic spring buffer 104 reduces the external impact force and keeps the battery assembly 10 stable. The outer frame assembly 1 and the inner frame assembly 2 provide protection for the battery assembly 10.

[0052] The temperature sensor 13 senses the temperature inside the battery shell 1001 in real time and sends the data to the controller 12. The controller 12 is electrically connected to the vehicle main control panel. The controller 12 presets a suitable operating temperature range for the battery, such as 0°C to 40°C, and presets an out-of-control temperature.

[0053] (2) Low temperature protection: When the temperature sensed by the temperature sensor 13 is lower than 0°C, the controller 12 starts the heating tube 902 to heat the coolant in the water tank body 901, starts the water pump 1 305 to pump out the coolant in the water tank body 901, starts the motor 303 to drive the flap 304 to rotate until the flap 304 is in a vertical state, and the front end of the square shell 301 is closed. The airflow when the car is driving will not flow through the center of the square shell 301. The coolant passes through the copper tube 306, and the heat conductive sheet 302 and the square shell 301 to exchange heat, thereby heating the battery body 1002 in the battery shell 1001 until it is heated to an appropriate temperature, such as 25°C. The three-way solenoid valve 307 and the channel of the cooling tube 1 7 are closed, and the coolant flows directly back to the water tank body 901 from the return pipe 308. The heating and cooling component 2 11 also works at the same time to maintain efficient heating. When the appropriate temperature is reached, the heating tube 902 and the water pump 1 305 are turned off.

[0054] (3) High temperature protection: When the temperature sensed by the temperature sensor 13 is higher than 40°C, the controller 12 starts the water pump 305 to pump out the coolant in the water tank body 901, which flows into the copper tube 306 and exchanges heat with the heat conductive sheet 302 and the square shell 301, thereby cooling the battery body 1002 in the battery shell 1001. At this time, the flap 304 is in a horizontal state. The airflow when the car is driving flows in from the front end of the square shell 301 and exchanges heat with the heat conductive sheet 302. The air cooling and water cooling cooperate to cool the battery body 1002. The three-way solenoid valve 307 closes the channel of the return pipe 308. The coolant flows back into the water tank body 901 through the cooling pipe 7. The heat sink 6 contacts the airflow to cool the coolant in the cooling pipe 7. The cooling pipe 2 8 and the heating and cooling component 2 11 perform the same cooling operation, with a good cooling effect, thereby maintaining the normal operation of the battery component 10.

[0055] (4) Overheating and overcharging protection: When the temperature sensed by the temperature sensor 13 is higher than the preset out-of-control temperature, such as 200°C, the controller 12 sends an alarm to the vehicle main control panel to remind the driver and passengers to stay away from the vehicle, and starts the water pump 2 903 to pump out the coolant in the water tank body 901 and inject it into the battery shell 1001 through the connecting pipe 904. The coolant is forced to cool the battery body 1002 on both sides of the battery body 1002, buying time for the passengers to escape.

[0056] The above is an exemplary description of the present invention in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
