Description

Technical Field

[0001] The present invention belongs to the technical field of energy storage battery packs, and in particular relates to a vehicle-mounted energy storage battery structure. Background Art

[0002] With the rise of new energy vehicles, energy storage battery packs have become key. Their main function is to store electrical energy. When the vehicle starts, they supply power to the motor, converting electrical energy into mechanical energy to drive the vehicle. It is the core element for new energy vehicles to achieve zero or low emissions, realize efficient energy management, and have good driving performance. It is of great significance to the development and promotion of new energy vehicle technology.

[0003] At present, the on-board energy storage battery structure mainly includes an energy storage battery pack, a frame, a shell, a cooling system, a battery management system, etc. Among them, the energy storage battery pack is a key component for storing electric energy. The cooling system is mainly for the energy storage battery pack to dissipate heat and ensure the stable operation of the energy storage battery pack. The battery management system controls the energy storage battery pack to work, and the frame, shell, etc. are mainly used to fix and protect the energy storage battery pack. For example, a vehicle-mounted energy storage battery structure disclosed in patent announcement number CN105161646B improves the protection effect of the energy storage battery by setting shock-absorbing structures inside the frame; During the operation of the energy storage battery, the protection effect of the energy storage battery pack can be improved by setting up shock-absorbing structures. However, when the energy storage battery pack encounters vibration, the energy storage battery moves and squeezes the shock-absorbing structure, which will generate additional heat (for example, when the rubber pad is compressed and rubbed, the mechanical energy will be partially converted into heat energy), and the energy storage battery will also generate more heat when it works, which will increase the overall temperature of the energy storage battery pack and increase the burden on the cooling system. Secondly, the shock-absorbing structure and the cooling system are arranged independently, which makes the structure complex, increases space, weight and cost, and makes coordinated regulation difficult, which hinders the overall performance improvement of the battery pack.

[0023] The liquid outlet unit 12 is arranged on one side of the base 1, and each sponge sleeve 8 is connected with the interior of the hollow block 10 through the liquid outlet unit 12. The interior of each sponge sleeve 8, the liquid inlet unit 11, the hollow block 10 and the liquid outlet unit 12 are all filled with coolant, and the coolant flows unidirectionally through the liquid inlet unit 11 and the liquid outlet unit 12.

[0024] The pushing unit 13 is installed inside the hollow block 10 for pushing the coolant.

After the flow detector 24 detects that the flow reaches the threshold, it can automatically feedback an electrical signal to the control main board 3.

[0027] The operating principle of the present invention is now described as follows: the entire device is installed on the chassis of the vehicle body, and the power supply end of the energy storage battery monomer 5 connected in series is connected to the power supply interface and the charging interface of the vehicle body through the electrode column 19. Then, the control mainboard 3 is connected to the power supply circuit of the vehicle body, and the data output interface of the control mainboard 3 is connected to the data input interface of the vehicle computer. When the vehicle is started or the vehicle is charged, the control mainboard 3 is started synchronously; During the normal driving of the vehicle, since the vehicle will generate vibration, the vibration is transmitted to the base 1 and each energy storage battery cell 5 through the frame. Under the action of the vibration, the energy storage battery cell 5 moves to one side. At this time, the energy storage battery cell 5 will squeeze each silicone rubber sleeve 6 and each sponge sleeve 8. Since the interior of each sponge sleeve 8 absorbs coolant, and since each upper circular hole 115 is installed with a liquid inlet check valve 116, and each lower circular hole 125 is installed with a liquid outlet check valve 126, the coolant can only enter the sponge sleeve 8 through the liquid inlet check valve 116, and the coolant inside the sponge sleeve 8 can only flow out through the liquid outlet check valve 126. When the sponge sleeve 8 is squeezed by the energy storage battery cell 5, since the sponge sleeve 8 itself has a porous structure, the coolant inside The porous structure of the sponge sleeve 8 is filled with coolant. When the energy storage battery cell 5 is squeezed, the incompressibility of the coolant requires the sponge sleeve 8 to overcome greater resistance during the compression process. The increase in this resistance helps to absorb more impact energy. Compared with the effect of buffering and shock absorbing the energy storage battery cell 5 only through structures such as rubber, the fluidity and incompressibility of the coolant can improve the shock absorbing and buffering performance of the energy storage battery cell 5. Since a plurality of liquid holes 25 and a plurality of transverse holes 26 are provided inside the sponge sleeve 8, and the pore diameters of the liquid holes 25 and the transverse holes 26 are larger than the microporous structure of the sponge sleeve 8, the liquid holes 25 and the transverse holes 26 can provide a larger flow path for the coolant. Therefore, when the sponge sleeve 8 is squeezed, most of the squeezed part is cooled. The liquid will flow down along the liquid through hole 25, and enter the lower circular hole 125 through the lower horizontal hole 26, and flow into the annular liquid outlet chamber 123 through the liquid outlet one-way valve 126. Since the cooling liquid inside the annular liquid outlet chamber 123 increases, part of the cooling liquid inside the annular liquid outlet chamber 123 will flow into the L-shaped liquid outlet pipe 121 through the shunt liquid outlet pipe 122, and flow into the hollow block 10 through the heat exchange pipe 127. When the energy storage battery body moves back and resets under the action of the rebound recovery of the silicone rubber sleeve 6, part of the cooling liquid inside the sponge sleeve 8 is squeezed out. Therefore, the cooling liquid inside the annular liquid inlet chamber 113 will be replenished into the sponge sleeve 8 through the upper circular hole 115 and the liquid inlet one-way valve 116, and the cooling liquid inside the hollow block 10 will be replenished into the sponge sleeve 8 through the L-shaped liquid inlet pipe 111. , the shunt liquid inlet pipe 112 and each liquid inlet connecting hole 114 are replenished into each annular liquid inlet cavity 113. Therefore, under the action of driving vibration, the coolant will circulate along the hollow block 10, the L-shaped liquid inlet pipe 111, the shunt liquid inlet pipe 112, the annular liquid inlet cavity 113, the liquid inlet connecting hole 114, the upper circular hole 115, the sponge cover 8, the lower circular hole 125, the annular liquid outlet cavity 123, the liquid outlet connecting hole 124, the L-shaped liquid outlet pipe 121 and the heat exchange pipe 127, which can not only improve the buffering and shock absorbing effect of the energy storage battery monomer 5, but also in the process of the flow of the coolant, it can bring out the heat generated by the energy storage battery monomer 5 at work, and exchange heat with the external environment through the heat exchange pipe 127 (the heat exchange pipe 127 can be arranged on the outside of the vehicle chassis when arranged,Make it contact with the outside air, use the running airflow or install special refrigeration equipment to cool the coolant, and ensure that the circulating coolant can continuously exchange heat and cool the energy storage battery cell 5); During the driving process of the vehicle, or during the charging process of the vehicle, when the vibration generated by the vehicle is relatively small and the frequency is relatively low, the energy storage battery cell 5 squeezes the sponge sleeve 8 to slow down the flow rate of the coolant. At this time, the cooling effect of the coolant on the energy storage battery cell 5 becomes worse, so the temperature of each energy storage battery cell 5 will gradually rise. At this time, each temperature probe 22 inside the annular liquid outlet cavity 123 will detect the increase in the coolant temperature, so the resistance of the thermistor inside each temperature probe 22 decreases (each thermistor is within a certain temperature range, such as within the range of -10°C to 200°C, its own resistance decreases with the increase in temperature). At this time, the overall resistance of the series circuit of the thermistor inside each temperature probe 22 and the measurement circuit of the control main board 3 decreases. Therefore, when the measurement voltage remains unchanged, the current intensity detected by the measurement circuit of the control main board 3 increases. When the current intensity exceeds the threshold value (the threshold value is set based on the heat dissipation requirement of the energy storage battery cell 5), the measurement circuit of the control main board 3 will send a signal to the control main board 3. 3, the control circuit of the control mainboard 3 feeds back an electrical signal, at which time the control mainboard 3 connects the connection circuit of the drive motor 135 with the thermistors of each temperature probe 22, and the drive motor 135 starts immediately, so that the drive shaft 133 can drive the impeller 132 to rotate through the gear transmission component 136. When the impeller 132 rotates, the coolant on one side of the heat exchange tube 127 inside the hollow block 10 can be transported to one side of the L-shaped liquid inlet pipe 111, so that the flow rate of the coolant can be accelerated, and then the heat dissipation and cooling effect of the coolant on the energy storage battery monomer 5 can be ensured. The higher the temperature of the energy storage battery monomer 5, the higher the temperature detected by each temperature probe 22, and the lower the resistance of the thermistor inside each temperature probe 22. Therefore, the greater the current intensity passed into the drive motor 135 at this time, the higher the output power of the drive motor 135, and the faster the rotation speed of the impeller 132, so that the flow rate of the coolant can be further accelerated to ensure that the coolant can meet the cooling efficiency of each energy storage battery monomer 5; Secondly, in daily driving, if the vibration frequency is higher and the vibration amplitude is larger, the energy storage battery cell 5 will be more seriously worn. At the same time, under the action of high-frequency vibration and large-amplitude vibration, the frequency and amplitude of the energy storage battery cell 5 squeezing the sponge sleeve 8 increase. Therefore, the faster the flow rate of the coolant, the faster the coolant speed passing through the detection tube 23. Similarly, when the temperature of the energy storage battery cell 5 is higher, the loss of its battery material may increase and the degree of aging increases. At the same time, the higher the temperature of the energy storage battery cell 5, the faster the flow rate of the coolant driven by the drive motor 135 to drive the impeller 132, so the coolant speed passing through the detection tube 23 will also increase, and the coolant passing through the detection tube 23 will also increase. When the speed of the coolant inside the tube 23 increases, the flow rate detected by the flow meter 24 will increase rapidly. Therefore, under high-frequency and large-amplitude vibrations, and when the temperature of the energy storage battery cell 5 is higher, the flow rate detected by the flow meter 24 will increase. When the flow meter 24 detects that the flow rate reaches a threshold value (the threshold value is set based on the interval time for the energy storage battery cell 5 to be maintained), the flow meter 24 will feedback an electrical signal to the control motherboard 3, and the control motherboard 3 will immediately output a warning signal to the vehicle computer. A prompt message will be displayed on the display screen of the vehicle computer to remind personnel to promptly inspect and maintain the energy storage battery cell 5, so as to eliminate hidden dangers in time and improve the operating stability of the energy storage battery cell 5; Among them, the blocking effect of the outer limit ring 27 on the inner limit ring 28 can prevent the energy storage battery cell 5 from being displaced too much under the action of vibration. Secondly, the inner limit ring 28 can prevent the energy storage battery cell 5 from being separated from the silicone rubber sleeve 6 when subjected to vibration force upward or downward. Secondly, since each energy storage battery cell 5 is connected by an electrode column 19, and each energy storage battery cell 5 is connected to the corresponding electrode column 19 through a connecting cable 20, when the energy storage battery cell 5 produces a slight displacement due to vibration, it will not pull each electrode column 19, thereby ensuring the stability of the electrical connection between each energy storage battery cell 5.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
