DESC:FIELD OF INVENTION
[0001] The present invention relates generally to thermal management systems for electric vehicles (EVs). More particularly, the invention concerns a system and method for optimizing the cooling performance of electrical drivetrain components in two-wheeler EVs by managing airflow through strategically positioned inlets, air-scoop outlets, and drivetrain components.

BACKGROUND OF THE INVENTION
[0002] The increasing adoption of electric vehicles (EVs) has brought significant advancements in technology, efficiency, and sustainability. However, maintaining optimal performance, reliability, and safety of EVs remains a critical challenge, particularly concerning thermal management. In electric vehicles, especially two-wheelers, the generation, dissipation, and management of heat are fundamental to the functionality and longevity of critical drivetrain components. Key components such as the motor control unit (MCU), battery, and motor are especially susceptible to heat accumulation during operation. If this heat is not managed effectively, it can degrade component efficiency, shorten service life, and, in extreme cases, lead to component failure or safety risks.
[0003] The battery, serving as the primary energy storage system in EVs, is highly sensitive to thermal variations. Elevated temperatures accelerate chemical degradation processes within the battery, resulting in reduced charge retention capacity, diminished state of health, and a shortened lifespan. Conversely, temperatures below the optimal range can impair power delivery, regenerative braking efficiency, and overall vehicle drivability. Frequent temperature fluctuations further exacerbate these issues, making thermal stability essential for preserving battery performance and ensuring consistent energy delivery during operation. Similarly, the motor control unit (MCU), which governs the electric motor's operation, generates significant heat during high-load conditions, such as rapid acceleration or hill climbing. Its complex circuitry and power electronics are particularly vulnerable to overheating, which can result in control malfunctions, reduced motor efficiency, and even system shutdowns. Effective cooling of the MCU is crucial to prevent these issues and ensure reliable operation under various driving conditions. The electric motor, as a key propulsion component, also generates considerable heat, especially during prolonged or high-load operations. Insufficient cooling of the motor can lead to thermal stress, reduced power output, and irreversible mechanical or electrical damage.
[0004] DE102016113394B3 relates to a thermal management method for operating a thermal management system of an internal combustion engine comprising an at least partially around a cylinder head of a cylinder of the internal combustion engine arranged with a fluid inlet chamber and an air-scoop outlet conduit, wherein the fluid chamber is connected to a coolant delivery device for delivery of a coolant and to at least one heat sink. It is proposed that a cylinder head temperature sensor, and/or a fluid chamber temperature sensor is included, wherein a volume flow of the coolant conveyor in dependence on an engine speed and/or fluid chamber temperature and/or engine load, by operating at least the first valve, is controllable. The heat management method provides that with increasing temperature of the fluid chamber, the flow rate of the coolant is increased by the heat sink temporarily, and at constant or by a maximum of 100 revolutions per minute increasing engine speed and reducing the engine load, the flow rate of the coolant through the Heat sink is not reduced from 60°C to 100°C after at least one minute after the load change and within a temperature range of the fluid chamber.
[0005] US8731789B2 discloses various systems and method for heating transmission fluid by directing the transmission fluid through a cylinder block of an engine. In one example, the transmission fluid is directed to flow through the cylinder block of the engine while engine coolant is directed to flow through the cylinder head of the engine. Further, the transmission fluid may be directed through one or more heat exchangers to cool the transmission fluid.
[0006] Various cooling strategies, including liquid-based, air-based, and hybrid systems, have been developed to address these thermal challenges. While liquid cooling provides efficient heat dissipation, it is often complex, heavy, and costly, making it less desirable for compact and lightweight vehicles such as two-wheelers. Air-based cooling systems, though simpler, lighter, and more cost-effective, often fail to deliver consistent and targeted cooling across all drivetrain components. In the specific context of two-wheeler EVs, the compact design, limited space, and weight constraints further complicate the implementation of effective thermal management solutions. Unlike larger vehicles, two-wheelers lack the structural framework needed to accommodate bulky cooling systems or additional thermal interfaces, resulting in uneven cooling and localized overheating, which diminish performance and reliability.
[0007] One of the most significant challenges in two-wheeler EVs is optimizing airflow for thermal management. Conventional air-based cooling systems typically rely on the natural flow of air as the vehicle moves to dissipate heat. However, this approach is limited by low-speed or stationary conditions, during which insufficient airflow causes heat to accumulate around critical components. Additionally, improper positioning of the MCU, battery, and motor can obstruct airflow, resulting in uneven cooling and the formation of hotspots that compromise system reliability. Inefficient venting of heated air exacerbates these issues by causing recirculation, where expelled hot air re-enters the cooling pathway, further impeding heat dissipation.
[0008] Given these challenges, there is a pressing need for a more efficient and space-conscious thermal management solution tailored to the requirements of two-wheeler EVs. Such a system must optimize the flow of air through strategically designed inlets, air-scoop outlets, and internal pathways to ensure uniform and efficient cooling of all critical components. It must provide targeted cooling for the hottest components, such as the MCU and motor, without compromising the cooling efficiency of other parts like the battery. Furthermore, it should operate effectively across a wide range of driving conditions, including low-speed or stationary scenarios, while integrating seamlessly with the vehicle's lightweight and compact design. A solution that meets these requirements would significantly enhance the thermal performance of two-wheeler EVs, improving their reliability, efficiency, and safety for users.

SUMMARY OF THE INVENTION
[0009] In light of the disadvantages mentioned in the previous section, the following summary is provided to facilitate an understanding of some of the innovative features unique to the present invention and is not intended to be a full description. A full appreciation of the various aspects of the invention can be gained by taking the entire specification and drawings as a whole.
[0010] In one aspect, the present invention provides a system for managing airflow to cool critical electrical drivetrain components in a two-wheeler electric vehicle. The system includes at least one inlet opening (102) located in a wheel-well, a floorboard (112) disposed above a motor control unit (106), and a battery (108) arranged rearward of the motor control unit (106). A motor (110) is positioned proximate to or behind the battery (108), and an air-scoop air-scoop air-scoop outlet (104) is disposed toward the rear portion of the vehicle.

It will nevertheless be understood that no limitation of the scope of the disclosure is thereby intended.

Similarly, one or more devices or sub-systems or elements or structures or components preceded by "comprises... a" does not, without more constraints, preclude the existence of other devices, sub-systems, elements, structures, components, additional devices, additional sub-systems, additional elements, additional structures, or additional components. Appearances of the phrase "in an embodiment", "in another embodiment" and similar language throughout this specification may, but not necessarily do, all refer to the same embodiment.
[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this disclosure belongs. The system, methods, and examples provided herein are only illustrative and not intended to be limiting.
[0023] Electric two-wheelers have rapidly emerged as a promising solution for eco-friendly urban mobility, yet they face significant challenges related to thermal management. The compact structure of these vehicles provides limited scope for airflow, while the increasingly powerful components they house—such as the motor, battery, and motor control unit—generate substantial heat. Under regular operating conditions, this heat must be dispersed efficiently to maintain optimal performance and prevent damage. Traditional cooling approaches, such as liquid-based systems, often prove too heavy or complex for two-wheeler configurations. Air-based cooling has accordingly become a popular approach, but ensuring that cool air circulates effectively around each of the critical components remains problematic. Constricted under-seat compartments, narrow body frameworks, and limited design flexibility can all compromise airflow, leading to the possibility of hot spots and inefficient cooling at lower speeds or during stops.
[0024] Compounding the issue, existing setups rarely account for the fact that each component may have distinct thermal thresholds and cooling demands. Batteries are highly sensitive to temperature changes, risking accelerated degradation when they overheat, while the motor and motor control unit can suffer from performance dips and long-term reliability issues if their heat is not managed properly. Additionally, poorly exhausted hot air can recirculate within the vehicle, raising interior temperatures and negating the benefits of any forced airflow system. These inherent constraints and design complexities create a gap in the technical field for a lightweight, cost-effective, and thoroughly integrated cooling arrangement that can direct airflow precisely and consistently to all heat-generating parts in a two-wheeler electric vehicle. Without such a solution, performance, reliability, and user safety remain at risk, highlighting the urgent need for an improved and carefully engineered thermal management system.
[0025] The present invention proposes a system for managing airflow (100) that utilizes strategically positioned inlets (102) and an air-scoop outlet (104) to cool critical drivetrain components in a two-wheeled electric vehicle. By guiding external air in a controlled manner over the motor control unit (106), battery (108), and motor (110), the invention ensures each component receives a dedicated stream of cooling air. This arrangement addresses the particular constraints of two-wheeler configurations, such as limited under-seat space and weight concerns, while maximizing the efficiency of air-based cooling. Rather than relying solely on incidental airflow or bulky liquid-cooling mechanisms, the system for managing airflow (100) capitalizes on natural air movements generated as the vehicle is in motion, as well as the engineered design of the inlets (102) and air-scoop outlet (104).
[0026] In essence, the invention leverages the interplay between vehicle forward motion, carefully shaped inlet openings (102), and a rearward air-scoop outlet (104) to provide a continuous flow of air across the drivetrain components. Each of these components—namely the motor control unit (106), battery (108), and motor (110)—is positioned along this airflow pathway, ensuring adequate dissipation of the heat generated during operation. By channeling the air sequentially, the system not only stabilizes the temperatures of individual parts but also prevents the buildup of hotspots that could degrade performance. The design further includes structural elements, such as the floorboard (112) and the seat (114), arranged so that airflow is guided effectively beneath or through specific sections of the vehicle without sacrificing rider comfort or the overall aesthetics of the two-wheeler.
[0027] To achieve these benefits, the inlet opening (102) is strategically placed in a wheel-well area to capture a flow of incoming air as the vehicle moves forward. This air is then funneled underneath the floorboard (112), ensuring that the motor control unit (106) remains among the first components to receive the cooling airflow. Because the motor control unit (106) can be particularly vulnerable to thermal overloads in higher-demand scenarios, its early placement in the airstream helps reduce the risk of overheating. From there, the airflow is naturally guided toward the battery (108), which is situated in a rearward position that both conserves space and enables balanced distribution of mass in the vehicle. Subsequent to the battery (108), the air continues to flow over the motor (110), offering a third layer of cooling for a component that can generate intense heat during acceleration or hill climbing.
[0028] By the time the airflow has passed over both the battery (108) and motor (110), it is then routed to the rear portion of the vehicle, where the air-scoop outlet (104) is located. Constructed as a vent, a scoop, or another form of discharge channel, the air-scoop outlet (104) expels the heated air away from the vehicle, preventing it from recirculating into the inlet opening (102). This arrangement preserves cool incoming air while ensuring that the overall heat generated by the drivetrain does not remain trapped inside the vehicle’s bodywork. The floorboard (112) and seat (114) cooperate to keep the air corridors clear, reducing turbulence and promoting a stable path of airflow. Such structuring is essential in retaining a steady, sequential flow that consistently cools the motor control unit (106), battery (108), and motor (110).
[0029] Additionally, the invention’s modular nature allows for various implementations of the inlet (102) and air-scoop outlet (104). The inlet (102) could be equipped with a shaped duct to improve the ram-air effect, while the air-scoop outlet (104) may feature multiple vents to expedite the removal of hot air. Alternative placements for the motor control unit (106), battery (108), or motor (110) may also be considered, provided they remain in the sequential path of airflow from the inlet (102) to the air-scoop outlet (104). In all such configurations, the core principle remains the same: harness the simplest, most direct airflow route through the vehicle to achieve efficient cooling for every critical drivetrain component. This solution thus presents a significant leap forward in addressing the constraints of two-wheeler electric vehicles, mitigating overheating risks, preserving component longevity, and ensuring reliable performance even under demanding conditions.
[0030] In FIG. 1, an exemplary two-wheeled electric vehicle is shown incorporating the system for managing airflow (100). This figure illustrates the inlet (102) located in the front wheel-well region, the air-scoop outlet (104) at the rear portion of the vehicle, and the critical drivetrain components: the motor control unit (106), battery (108), and motor (110). It also depicts the floorboard (112) positioned above the motor control unit (106), and the seat (114) located above the battery (108) and motor (110). By showing all these reference numerals in a single diagram, FIG. 1 provides an overview of how the various elements are arranged within the vehicle to ensure a continuous and directed flow of air from front to rear.
[0031] Turning to FIG. 2, a closer view of the inlet (102) is presented. This inlet (102) is positioned near the front wheel, where it can capture air as the vehicle moves forward. In some implementations, it may include a shaped duct or grill to enhance the ram-air effect, ensuring that a sufficient volume of air enters the system. The inlet (102) serves as the starting point for the cooling process, channeling fresh air beneath the vehicle and directing it toward the drivetrain components located downstream.
[0032] In FIG. 3, the floorboard (112) is illustrated with the motor control unit (106) situated underneath it. This arrangement ensures that as soon as air enters from the inlet (102), it passes over and around the motor control unit (106), drawing away the heat generated during higher load conditions. Placing the MCU (106) in this position not only facilitates early-stage cooling but also contributes to an efficient layout that keeps the component central to the vehicle’s underbody, making optimal use of the incoming air.
[0033] Moving on to FIG. 4, the battery (108) and motor (110) are shown nestled beneath the seat (114). By positioning these critical components in the path of air that has already cooled the motor control unit (106), the system ensures that heat from both the battery (108) and the motor (110) is likewise carried away as the airflow progresses. The battery (108) is arranged to receive continuous cooling over its external surfaces, mitigating any risk of overheating or cell degradation, while the adjacent or rearward positioning of the motor (110) allows it to benefit from the same directed stream of air.
[0034] In FIG. 5, the rear portion of the floorboard (112) is depicted, demonstrating how airflow is maintained and directed as it proceeds past the battery (108) and motor (110). The design of the floorboard (112) and surrounding panels minimizes turbulence and ensures that the moving air does not become trapped or diverted away from the critical components. Instead, it continues in a controlled manner toward the back of the vehicle, where it is eventually expelled.
[0035] In FIG. 6, the air-scoop outlet (104) is highlighted at the rear portion of the vehicle. This air-scoop outlet (104) may include vents, louvers, or a scoop that facilitates efficient discharge of heated air away from the vehicle’s underbody. By locating the air-scoop outlet (104) in a region with minimal airflow interference, the system prevents hot air from recirculating into the inlet (102) and ensures that the airflow remains fresh and cool for subsequent rounds of heat dissipation.
[0036] Finally, FIG. 7 offers an illustrative representation of the overall airflow pathway, shown in directional arrows without specific reference numerals. Cool air is drawn into the vehicle through the front inlet, travels sequentially over the motor control unit, battery, and motor, then exits via the rear air-scoop outlet. The arrows make clear how the system establishes a continuous and orderly route for air to absorb and carry off heat from the drivetrain components, thereby maintaining more stable operating temperatures across all critical parts of the electric two-wheeler.
[0037] The present invention offers significant advantages in the field of thermal management for two-wheeled electric vehicles by providing a highly efficient and space-conscious airflow management system. A key advantage lies in its ability to cool critical drivetrain components—namely the motor control unit (106), battery (108), and motor (110)—in a sequential and targeted manner. By leveraging strategically positioned inlet openings (102) and an air-scoop outlet (104), the system ensures that each component receives adequate cooling without the need for additional weight-intensive or complex mechanisms such as liquid-based cooling. This not only enhances the overall performance and reliability of the vehicle but also extends the service life of the components by preventing overheating and thermal degradation, even under demanding conditions.
[0038] Another notable advantage of the invention is its simplicity and cost-effectiveness. The design primarily relies on the vehicle's natural motion to channel air effectively through the drivetrain components, eliminating the need for external power or forced airflow systems in most configurations. This reduces both manufacturing costs and energy consumption during operation, contributing to the vehicle's efficiency. The system is lightweight and integrates seamlessly with the compact structure of two-wheeler EVs, ensuring that the cooling arrangement does not compromise the vehicle’s weight balance, handling, or rider ergonomics. Furthermore, the modular design allows for easy implementation and adaptability across different vehicle models, enabling manufacturers to tailor the system to various drivetrain layouts and aesthetic preferences.
[0039] The invention also enhances the safety and drivability of the electric vehicle by maintaining optimal operating temperatures for all critical components. The motor control unit (106) benefits from stable temperatures that prevent control malfunctions, while the motor (110) and battery (108) can deliver consistent performance without the risks associated with overheating. Additionally, by venting heated air through the air-scoop outlet (104) at the rear of the vehicle, the system prevents recirculation of hot air into the cooling pathway, ensuring a continuous supply of fresh, cool air for efficient heat dissipation. These advantages collectively make the invention a robust, versatile, and user-friendly solution, setting a new standard in thermal management for compact electric vehicles.
[0040] The primary use case for this invention is in two-wheeled electric vehicles, where the need for efficient thermal management is critical due to limited space and the high heat output of drivetrain components such as the motor control unit (106), battery (108), and motor (110). By channeling air sequentially through these components via strategically placed inlet openings (102) and an air-scoop outlet (104), the system ensures optimal cooling in a lightweight and cost-effective manner. This makes the invention particularly suited for urban mobility solutions, such as electric scooters and motorcycles, which must operate reliably in diverse environmental and traffic conditions, including stop-and-go scenarios where traditional air-based cooling systems often underperform.
[0041] Beyond two-wheeled electric vehicles, the invention can be adapted for other compact electric vehicles, including three-wheeled vehicles, small four-wheeled electric cars, and even non-road applications like autonomous delivery robots or electric golf carts. These vehicles often face similar constraints of limited space and weight, making the described airflow management system an ideal solution. The modular design allows for modifications to the inlet (102) and air-scoop outlet (104) configurations to accommodate different component placements or vehicle geometries. For example, in a small electric car, the inlet could be integrated into the front grille while multiple air-scoop outlets might be used at the rear to enhance airflow and heat dissipation for larger batteries and motors.
[0042] The principles of this invention can also extend to non-vehicular applications that require precise and efficient cooling of heat-generating components. Examples include compact industrial machinery, server racks, and portable electronic devices with high thermal loads. In such use cases, the inlet and air-scoop outlet design, along with the strategic placement of components, can be tailored to facilitate targeted airflow for optimal heat management. Additionally, this system could be incorporated into emerging technologies such as drones or aerial delivery vehicles, where lightweight, passive cooling mechanisms are essential to balance thermal performance with operational efficiency. By broadening the scope of the invention to these alternative applications, the described system demonstrates its versatility and potential for widespread adoption in various fields.
[0043] In conclusion, the present invention provides an innovative and efficient system for managing airflow to cool critical drivetrain components in two-wheeled electric vehicles and beyond. By leveraging strategically positioned inlets, air-scoop outlets, and component placements, the invention addresses longstanding challenges in thermal management with a lightweight, cost-effective, and adaptable design. It not only enhances the performance, reliability, and lifespan of components such as the motor control unit, battery, and motor but also ensures safe and efficient operation under varying conditions. The system’s versatility allows it to be applied across a wide range of vehicle types and non-vehicular applications, highlighting its potential to redefine thermal management solutions in compact and space-constrained environments. This invention represents a significant advancement in the field, promising to deliver substantial benefits to manufacturers and users alike.
