Defining the Component: The Critical Interface for Battery Thermal Management
To fully grasp the market’s dynamics and strategic importance, one must first understand what an EV battery liquid cooling plate is and why it is so fundamentally important to electric vehicle performance and safety.
A battery liquid cooling plate is a component within the battery thermal management system (BTMS) that directly exchanges heat with the battery cells or modules. Its operating principle is elegantly simple yet critically effective: it features internal microchannels through which a coolant (typically a water-glycol mixture) circulates. This coolant absorbs the heat generated by the battery during charging and discharging, transporting it to a radiator or heat exchanger where it is dissipated. Conversely, in cold conditions, the system can circulate warm coolant to heat the battery, bringing it into its optimal operating range.
The cooling plate is typically made of materials with high thermal conductivity, most commonly aluminum alloys, chosen for their excellent heat transfer properties, light weight, and formability. The plate is installed in direct contact with the battery cells, often with a thermally conductive interface material to enhance heat transfer.
The key functions of the battery liquid cooling plate are:
- Heat Dissipation: To remove the heat generated during high-power discharge (e.g., during acceleration) and, most critically, during fast charging, preventing dangerous overheating and thermal runaway.
- Temperature Uniformity: To maintain a consistent temperature across all battery cells within the pack. Temperature gradients can lead to uneven cell aging, reducing overall pack performance and lifespan.
- Cold-Weather Heating: To warm the battery in low-temperature environments, ensuring sufficient power output and enabling faster charging.
The market is segmented by the manufacturing technology and structure of the cooling plate into several key types, each with distinct characteristics and applications:
- Harmonica Tube Type: These plates use flattened tubes (like a harmonica) through which coolant flows. While offering good heat exchange and design flexibility, they are more expensive to produce and can be difficult to install due to flatness requirements. The report suggests this type may be gradually phased out due to competition from more advanced technologies.
- Brazed Type (Stamping): This is currently the mainstream technical direction, especially for high-performance BEVs and fast-charging applications. Formed by stamping two metal sheets and brazing them together, these plates allow for complex, customized flow channels that maximize heat dissipation area and ensure uniform temperature distribution. Their thin-wall design also supports lightweighting goals.
- Inflation Type: These plates are formed by inflating a welded metal sheet to create internal channels. They offer optimized heat dissipation paths but suffer from higher costs, lower manufacturing yields, and are difficult to repair if damaged. They are currently used mainly in high-end models and customized battery packs.
These cooling plates are critical for all types of electrified vehicles, with the dominant application being Battery Electric Vehicles (BEVs) , which in 2024 accounted for over 70% of the application share. They are also essential for Plug-in Hybrid Electric Vehicles (PHEVs) and other emerging applications.

High-performance liquid cooling plates with optimized flow channels are absolutely essential for dissipating this heat quickly and safely, preventing battery degradation and ensuring user safety. The transition to 800V architectures, which enable faster charging, further amplifies the need for advanced thermal management and drives demand for more sophisticated, higher-performance cooling plates.
3. The Technological Evolution Toward Lightweighting and Integration
The future of battery cooling plates is being shaped by several powerful technological trends:
- Lightweighting and Advanced Materials: There is a continuous push to reduce weight using aluminum composites, explore the potential of graphene coatings for enhanced thermal conductivity, and even utilize 3D-printed structures for optimized designs.
- Integrated Design (CTP/CTC): The adoption of Cell-to-Pack (CTP) and Cell-to-Chassis (CTC) technologies, where cells are integrated directly into the battery pack or vehicle structure, is driving demand for deeply integrated cooling plates that become a structural part of the battery assembly. This reduces complexity, saves space, and improves efficiency.
- Smart Thermal Management: The integration of sensors and AI-driven control systems enables dynamic, zonal temperature regulation. This allows the system to precisely target cooling or heating where it is needed most, optimizing performance and energy use, especially during ultra-fast charging or in extreme climate conditions.
- Multifunctional Systems and Sustainability: There is a growing trend to integrate the battery cooling loop with the vehicle’s heat pump system, enabling the reuse of waste heat for cabin heating in winter. This improves overall vehicle efficiency. Simultaneously, there is a shift toward using recyclable materials for the plates and more eco-friendly coolants (e.g., propylene glycol replacing ethylene glycol).
