CROSS REFERENCE TO RELATED APPLICATIONS
The present application claims priority from Indian Provisional Patent Application No. 202421049562 filed on 28/06/2024, the entirety of which is incorporated herein by a reference.
TECHNICAL FIELD
The present disclosure generally relates to a battery pack. Particularly, the present disclosure relates to a cooling plate for a battery pack of an electric vehicle. Furthermore, the present disclosure relates to a method of manufacturing a cooling plate for a battery pack of an electric vehicle.
BACKGROUND
Recently, there has been a rapid development in battery packs because of their use as clean energy storage solution for various uses ranging from domestic use to transportation use. The battery pack comprises a set of any number of identical batteries or individual battery cells. The battery cells are assembled as cell arrays and multiple cell arrays are combined to form the battery packs.
Each battery pack comprises a plurality of cells and cell holders for securing the plurality of cells. These battery cells are electrically connected to form cell arrays and multiple cell arrays can be stacked together to form the battery pack, being used as a single unit for meeting high voltage and current requirements. However, the battery pack generates a large amount of heat during the charging and discharging process. If heat generated during the charging and discharging process is not effectively eliminated, heat accumulation may occur inside the battery, which results in accelerated deterioration of the battery cells. Moreover, in some conditions such heat accumulation may even lead to hotspots causing thermal runaway which would permanently damage the battery pack. Furthermore, the thermal runaway may lead to fire and/or explosion causing safety risks.
Generally, to eliminate the heat and prevent resultant damages, a cooling jacket is placed on the outer surfaces such as the casing of the battery pack. However, such a cooling structure can only extract heat from the outer portions of the battery pack, leaving the inner portions of the battery pack at a higher temperature. Thus, a temperature gradient is formed between the inner and outer portion of the battery pack which leads to poor cell performance and higher degradation rate. To reduce the temperature gradient and extract heat from the inner portions of the battery pack, a submerged cooling technique is used wherein all the battery cells of the battery pack are submerged in a coolant. The battery pack with coolant-submerged battery cells have a lower temperature gradient between the outer and inner portions of the battery pack. However, the use of such a cooling technique leads to an increase in the weight of the battery pack. Furthermore, the size and cost of the battery pack is also increased significantly. Moreover, such cooling techniques add unnecessary bulk to the already bulky battery pack. Furthermore, the added weight and size affects the performance of the battery pack in mobile application such as electric vehicles.
Therefore, there exists a need of an improved solution for a cooling plate of a battery pack that overcomes one or more problems associated as set forth above.

The battery pack is configured to store and deliver electrical energy to power a load, such as an electric motor in an electric vehicle.
As used herein, the term “composite material” refers to a material system composed of two or more distinct constituent materials that remain chemically separate within the final structure, wherein the constituents are combined to achieve properties that are superior or significantly different from those of the individual components. Typically, a composite material comprises a matrix material, which forms the continuous phase, and a reinforcement or filler material, which is embedded within the matrix to enhance specific mechanical, thermal, or electrical properties. The composite material comprises a thermoplastic matrix and a thermally conductive filler material dispersed within the matrix to improve thermal conductivity while maintaining structural integrity and processability.
As used herein, the term “thermoplastic matrix” refers to the continuous phase of a composite material composed of a thermoplastic polymer, which serves as the primary binding and structural medium in which filler materials are uniformly dispersed. The thermoplastic matrix provides mechanical integrity, shape retention, and processability to the composite. The suitable thermoplastic matrices include, but are not limited to, epoxy, polycarbonate, polycarbonate blends, polyphenylene ether, polypropylene, and polyethylene terephthalate. The selection of the thermoplastic matrix may be based on desired mechanical strength, thermal stability, chemical resistance, and compatibility with thermally conductive filler materials.
As used herein, the term “thermally conductive filler” refers to a material or a combination of materials that are dispersed within a base matrix (such as a polymer or thermoplastic) to enhance the ability to conduct heat. The thermally conductive fillers are characterized by having a higher thermal conductivity than the surrounding matrix material and are incorporated to form a thermally conductive path, thereby improving the overall thermal performance of the composite. The thermally conductive filler may include, but is not limited to, one or more of: carbon-based materials (such as graphite, graphene, single-walled carbon nanotubes, or multi-walled carbon nanotubes), ceramic materials (such as boron nitride or aluminium nitride), or metallic particles (such as copper or aluminium), which may be in the form of particles, flakes, fibres, or nanostructures.
As used herein, the term “additive manufacturing” refers to a process of fabricating a three-dimensional object by successively depositing material layer by layer based on a digital model, wherein the object is formed by the addition of material rather than by subtractive methods such as cutting or machining. The additive manufacturing process may include, but is not limited to, techniques such as fused deposition modelling (FDM), selective laser sintering (SLS), stereolithography (SLA), direct energy deposition (DED), or binder jetting, depending on the type of material and desired structural configuration.
As used herein, the term “plurality of single-walled nanotubes” and “single-walled nanotubes” are used interchangeably and refer to a composition including multiple individual carbon nanotubes, each comprising a single cylindrical layer of carbon atoms arranged in a hexagonal lattice structure. The single-walled nanotubes are typically formed as seamless tubes of graphene and exhibit high thermal conductivity, mechanical strength, and electrical conductivity.
As used herein, the term “plurality of multi-walled nanotubes” and “multi-walled nanotubes” are used interchangeably and refer to a collection of multiple carbon nanotube structures, each comprising multiple concentric cylindrical graphene layers (walls) arranged in a coaxial manner around a common central axis. The multi-walled carbon nanotubes exhibit high thermal conductivity, mechanical strength, and chemical stability.
As used herein, the term “continuous network” refers to an interconnected structure formed by the thermally conductive filler material within the thermoplastic matrix, wherein the filler material establishes a substantially uninterrupted thermal conduction pathway across the matrix.

As used herein, the term “thermal conductivity” refers to the intrinsic property of a material that quantifies its ability to conduct heat. The thermal conductivity defined as the rate at which heat passes through a unit area of the material, having a unit thickness, when subjected to a unit temperature gradient under steady-state conditions. The thermal conductivity is typically expressed in units of watts per meter-kelvin (W/m·K), and higher thermal conductivity values indicate greater efficiency in transferring heat through the material.
As used herein, the term “liquid cooling system” refers to a thermal management system configured to regulate the temperature of a component such as a battery pack by circulating a liquid coolant through one or more fluidic channels, conduits, or chambers in thermal communication with the component. The liquid coolant absorbs heat from the component and transfers the coolant to a remote heat exchanger or radiator, where the heat is dissipated to the ambient environment. The system may include elements such as a coolant reservoir, pump, valves, sensors, and control electronics to ensure stable and efficient operation under varying thermal loads. The liquid coolant may comprise water, glycol-based mixtures, dielectric fluids, or any suitable fluid with desired thermal and chemical properties.
As used herein, the term “phase change material cooling system” and “PCM” are used interchangeably and refer to a thermal management system that utilizes a material capable of absorbing and releasing a significant amount of latent heat during its phase transition, typically from solid to liquid or vice versa, at a specific temperature range. The phase change material is positioned in thermal contact with the battery cells or integrated within the cooling plate. During battery operation, when the temperature increases beyond a threshold, the PCM absorbs heat and undergoes a phase change, thereby regulating the temperature by delaying further rise. Upon cooling, the PCM re-solidifies, releasing the stored thermal energy. This passive cooling approach helps maintain battery temperature within optimal operating limits, enhancing battery performance, safety, and cycle life without requiring continuous energy input.
Figure 1a & 1b, in accordance with an embodiment describes a cooling plate 100 for a battery pack of an electric vehicle. The cooling plate 100 is made of a composite material. The composite material comprises a thermoplastic-matrix 102 and a thermally conductive filler material 104 dispersed within the thermoplastic-matrix 102. The cooling plate 100 is formed by additive manufacturing.
In an embodiment, the thermoplastic-matrix 102 is selected from at least one of epoxy, polycarbonate, polycarbonate blends, polyphenylene ether, polypropylene, or polyethylene terephthalate. The selection of the thermoplastic materials allows the cooling plate 100 to exhibit desirable characteristics such as high thermal stability, good mechanical strength, chemical resistance, and processability suitable for additive manufacturing. For instance, polycarbonate and the polycarbonate blends offer impact resistance and high heat deflection temperature, while polypropylene and polyethylene terephthalate provide lightweight properties and good dimensional stability. The epoxy and polyphenylene ether enhance thermal and electrical insulation characteristics. The thermoplastic- matrix 102 act as the primary structural framework in which thermally conductive filler materials 104 are uniformly dispersed, thereby enables the cooling plate 100 to serve as an efficient thermal interface in the battery pack of the electric vehicle.
In an embodiment, the thermally conductive filler material 104 is selected from at least one of a plurality of single-walled carbon nanotubes, a plurality of multi-walled carbon nanotubes, boron nitride, or a plurality of nanoparticles. The thermally conductive filler materials 104 may be uniformly dispersed within the thermoplastic matrix 102 to form the composite structure that enhances the overall thermal conductivity of the cooling plate 100. The selected filler materials possess the high intrinsic thermal conductivity and are effective in forming the conductive pathways for efficient heat dissipation from the battery cells during vehicle operation. The use of carbon nanotubes, in both single-walled and multi-walled forms, provides the exceptional thermal transfer due to the high aspect ratio and conductive nature. Alternatively, the boron nitride offers high thermal conductivity with electrical insulation, which is advantageous for avoiding short circuits in electrically sensitive battery environments. Subsequently, the use of nanoparticles, depending on the composition and dispersion, contributes to improving the thermal performance by reducing thermal resistance across the composite structure. Beneficially, the conductive filler material 104 ensures that the cooling plate 100 maintains the uniform thermal gradients and supports efficient heat removal, thereby protecting the battery pack from thermal stress and enhancing operational reliability.
In an embodiment, the thermally conductive filler material 104 forms a continuous network within the thermoplastic-matrix 102 to enhance thermal conductivity. The continuous network of the thermally filler material 104 may be structured such that the filler material 114 creates an uninterrupted thermal pathway across the body of the cooling plate 100, thereby significantly enhances the effective thermal conductivity of the composite. The network structure enables rapid and uniform heat transfer away from localized high-temperature regions, such as those occurring near the battery cell interfaces. The formation of the continuous network may be achieved through controlled dispersion techniques during the composite formulation and through directional deposition methods facilitated by additive manufacturing processes. As a result, the thermal management efficiency of the cooling plate 100 is improved, supporting stable battery operation, preventing overheating and contributing to the prolonged life and performance of the battery pack.
In an embodiment, the cooling plate 100 comprises at least one of fins, channels, or lattice structures to increase heat dissipation efficiency. The structural features may be configured to increase the effective surface area of the cooling plate 100, thereby improving the thermal exchange with the surrounding environment or with a secondary cooling medium such as air or liquid. The fins may be oriented vertically or horizontally depending on the installation geometry, while the channels may be designed to allow the flow of coolant fluid through or along the cooling plate 100. Alternatively, or in addition, the lattice structures may be formed within or on the surface of the plate to promote multi-directional heat conduction and dissipation. Beneficially, the structural features are enabled using additive manufacturing techniques, which allow the precise fabrication of complex geometries directly into the cooling plate 100 without the need for secondary assembly operations. Moreover, the integration of such geometrical enhancements contributes to improved thermal management of the battery pack, enables more uniform temperature distribution and reduces the risk of thermal runaway.
In an embodiment, the cooling plate 100 is configured to be integrated with a liquid cooling system or a phase change material cooling system. The integration with the liquid cooling system enhances the thermal regulation of the battery pack. Moreover, the liquid cooling system may involve embedding one or more fluid channels within or adjacent to the cooling plate 100, allows a coolant to flow through and actively extract heat from the battery cells. The thermally conductive filler material 104 of the cooling plate 100 facilitates the efficient heat transfer from the battery cells to the circulating coolant, thereby maintaining optimal battery operating temperatures. Alternatively, the cooling plate 100 may be designed to interface with or encapsulate the phase change material, which passively absorbs the heat by undergoing a solid-to-liquid phase transition. In the PCM based configuration, the PCM is positioned in thermal communication with the surface of the cooling plate 100 or embedded within the structure, such that as the battery generates heat during operation, the PCM absorbs the heat and transitions phases, thereby preventing the rapid temperature rise. The dual compatibility with both active and passive cooling mechanisms provides the cooling plate 100 with enhanced versatility and adaptability for use in various electric vehicle battery architectures.
The present disclosure provides the cooling plate 100 for the battery pack of the electric vehicle. The coolant plate as disclosed by present disclosure is advantageous in terms of the efficient and reliable thermal management of electric vehicle battery packs. Beneficially, by utilizing the composite material comprising the thermoplastic matrix 102 and the thermally conductive filler material 104, the cooling plate 100 ensures an optimized balance between mechanical integrity, weight reduction, and thermal performance. Beneficially, the thermoplastic matrix 102 offers the lightweight and corrosion-resistant properties while maintaining the structural flexibility, making the cooling plate 100 suitable for integration into compact EV battery modules. The inclusion of the high-performance conductive filler materials 104 such as the carbon nanotubes, boron nitride, or nanoparticles allows the formation of the thermally conductive network, significantly improves the heat transfer across the cooling plate 100 and mitigating local hotspots that may degrade battery performance. Moreover, the use of additive manufacturing enables complex geometric features such as integrated fins, channels, or lattice structures, which further enhance the convective and conductive heat dissipation efficiency without requiring post-processing. The additive manufacturing approach also allows for design optimization, weight savings, and scalable production. Additionally, the cooling plate 100 may be seamlessly configured for integration with both liquid cooling and phase change material (PCM) cooling systems, thereby increasing the applicability across different EV architectures and thermal control strategies. The integration with PCM systems provides the passive thermal buffer by utilizing latent heat, while liquid systems offer active cooling potential, together offering flexible and modular cooling solutions.
