Description:FIELD OF INVENTION
[0001] The present invention is generally related to a battery cooling system, and more particularly to a battery cooling system and method for use with an electric vehicle.
BACKGROUND OF INVENTION
[0002] As electric vehicles continue to gain prominence as the future of transportation, manufacturers (OEMs) are increasingly focused on optimizing the performance of key components such as the motor and battery, which serve as the primary power sources.
[0003] Through market feedback, it has become evident that heating issues with the motor and battery are prevalent concerns among users. Excessive heat buildup poses significant risks, including the potential for battery cell explosions. Therefore, ensuring adequate cooling in the motor and battery areas is essential for maintaining optimal operating conditions and enhancing overall vehicle efficiency, especially at high speeds.
[0004] The chemistry of battery cells is complex, and maintaining the correct temperature is crucial to prevent hazardous situations. Forced convection, which involves directing airflow toward the battery, is necessary to regulate temperature, even while the vehicle is in motion. However, incorporating fans for this purpose can present challenges, including increased power consumption and reduced vehicle performance due to the space they occupy.
[0005] Inadequate cooling of the battery can lead to overheating, necessitating larger battery sizes to accommodate poor thermal management. Conversely, optimizing or increasing airflow can minimize thermal impact, allowing for the use of smaller, more efficient battery sizes without compromising performance.
[0006] US patent US9403574B2 issued to Jeff Sand et al. discloses vent holes that allow air to flow through the radiator and exit a frame. In addition to having the ability to cool the motor with a coolant, the frame itself can act as a heat sink. Aluminum is a very good heat conductor, and the shape of the frame structure allows excess heat to travel from the motor housing to the left and right sides of the frame structure where the heat may be dissipated via air convection, conduction to attached parts, or radiation.
[0007] US patent US8833495B2 issued to Kobue Iwata et al. talks about an electrical component box for storing electrical components disposed in the rear of the battery. This makes it possible to efficiently cool the battery and the electrical components with the traveling wind flowing in a vehicle's longitudinal direction.
[0008] Therefore, effective thermal management systems that promote optimal airflow around the motor and battery are crucial for enhancing safety, efficiency, and performance in electric vehicles.
[0009] Thus, in view of the above, there is a long-felt need in the industry to address the aforementioned deficiencies and inadequacies.

[0039] The present disclosure outlines a highly efficient battery cooling system designed to maximize airflow for effective battery cooling. This system employs an efficient airflow mechanism, as demonstrated in experiments where airflow was observed on 5 out of 6 faces of the battery. Consequently, the battery temperature rises only 6 to 8 degrees during 1.5C rating discharging, compared to the conventional battery's rise of around 13 to 15 degrees. This allows for the design of relatively smaller battery capacities, reducing vehicle costs without compromising performance metrics such as maximum speed, gradient handling, and acceleration. Moreover, the battery cooling system enables the maintenance of motor specifications even with a smaller battery. Importantly, the highly efficient cooling system is implemented without any additional costs to the vehicle, as it utilizes vent openings strategically placed for air intake and outlet on various components, resulting in an optimized cooling system. Notably, no fans or complex cooling systems like radiators are incorporated, simplifying the overall design and reducing manufacturing complexity.

[0045] FIG. 10 illustrates a perspective view of an airflow tunnel 1000 created below the battery pack 202 of the electric vehicle 102, in accordance with at least one embodiment. In the experiment, conducted with the assistance of computational fluid dynamics (CFD) simulation tools, the airflow inside the battery bin was analyzed to visualize the air's ingress and egress points. Based on fundamental principles of physics, wherein air flows from high-pressure regions to low-pressure ones, coupled with simulation trials, the locations for air escape vents were determined. These air vents are not limited to the rear side of the battery bin but are also positioned along its side walls, rendering it a five-directional cooling component. By providing these escape vents, a continuous flow of air around the battery area is ensured. Air is drawn in through the front-side vents and exits through the rear and side wall vents of the bin.
[0046] Without proper air escape vents, trapped air within the battery bin would absorb heat from the battery, increasing surrounding temperatures. Trapped air permits heat transfer solely through conduction, leading to a slower rate of cooling. Escape air vents facilitate continuous airflow, preventing an increase in the surrounding temperature. Airflow enables heat transfer through convection, a more efficient method than conduction, ensuring optimal cooling.
[0047] Consequently, during battery discharging, the temperature rise is only 6 to 8 degrees Celsius with high airflow, which efficiently dissipates heat from the battery through the battery bin. This is in stark contrast to conventional batteries, which experience a temperature rise of 13 to 15 degrees Celsius due to the absence of airflow. Moreover, standard battery operating cut-off temperatures are around 57 to 58 degrees Celsius. Beyond this threshold, battery performance is reduced to 70% or 50% of capacity, impacting vehicle speed or necessitating vehicle stoppage until the battery cools down, which can be inconvenient for customers.
[0048] In an embodiment, the electric vehicle features a motor with a maximum input of 80Ah. A conventional battery supplying power to such a motor would require 60Ah, resulting in a temperature rise of approximately 7 to 8 degrees Celsius. However, the present invention utilizes a smaller 45Ah battery, which would typically experience a temperature rise of 13 to 15 degrees Celsius when powering an 80Ah motor. Through the refined battery cooling system outlined above, proper airflow is maintained, resulting in a temperature delta within 6 to 8 degrees Celsius for the smaller 45Ah battery instead of the conventional 60Ah. This ensures the battery remains undeterred, thereby preserving electric vehicle speed, handling on gradients, and acceleration. Additionally, traditional methods of achieving high airflow for battery cooling, such as cooling fans or radiators, incur additional costs, making vehicles more expensive. However, the present invention achieves the desired airflow within existing electric vehicle components, eliminating the need for additional parts and associated costs while ensuring efficient battery cooling. In one embodiment, multiple air intake vents are strategically positioned at the inlet areas of various components within the battery cooling system. These vents are meticulously placed based on the geometry of different components, aligning the parts to direct airflow toward the battery area and ensuring a consistent and turbulent airflow domain for effective battery cooling.
[0049] Similarly, in another embodiment, various air outlet vents are strategically placed to provide an efficient escape route for the incoming air. Proper vent positioning is crucial to prevent air trapping, which could disrupt airflow and compromise system performance. Rear side vents located at the battery bin facilitate proper airflow, while vents and cut-outs at the rear and side areas of the battery bin ensure adequate airflow around the battery area. Cooling efficiency is typically measured in terms of CFM (cubic feet per minute), with optimal battery and motor performance achieved at 38 CFM of cooling, as determined through battery testing. To accommodate this airflow requirement without sacrificing the overall aesthetics of the electric vehicle, the battery bin and relevant body parts are designed with appropriately sized openings. Additionally, in another embodiment, airflow velocity is assessed in meters per second (m/s), necessitating a conversion from CFM to m/s. Through calculations, it is determined that an airflow velocity of 1.8 m/s is required for effective cooling.
[0050] Given that 1 CFM is equivalent to approximately 0.0004719474 m^3/sec, and with 38 CFM translating to 0.0179340028 m^3/sec, the total surface area of the vents and cut-outs on the battery bin's front side for air inlet is calculated to be 9456.5344 mm^2. Converting the airflow rate from m^3/sec to m/s yields a value of 1.896 m/s, indicating that an inlet air velocity of 1.896 m/s is necessary to ensure proper battery cooling.
[0051] As used herein, and unless the context dictates otherwise, the term “configured to” or “coupled to” is intended to include both direct coupling (in which two elements that are coupled to each other contact each other) and indirect coupling (in which at least one additional element is located between the two elements). Therefore, the terms “configured to”, “configured with”, “coupled to” and “coupled with” are used synonymously. Within the context of this document terms “configured to”, “coupled to” and “coupled with” are also used euphemistically to mean “communicatively coupled with” over a network, where two or more devices can exchange data with each other over the network, possibly via one or more intermediary device.
[0052] It should be apparent to those skilled in the art that many more modifications besides those already described are possible without departing from the inventive concepts herein. The inventive subject matter, therefore, is not to be restricted except in the scope of the appended claims. Moreover, in interpreting both the specification and the claims, all terms should be interpreted in the broadest possible manner consistent with the context. In particular, the terms “comprises” and “comprising” should be interpreted as referring to elements, components, or steps in a non-exclusive manner, indicating that the referenced elements, components, or steps may be present, utilized, or combined with other elements, components, or steps that are not expressly referenced.
