EV battery thermal management

Automotive

The automotive industry is undergoing its most significant transformation through total electrification and advanced electronic integration. Current development focuses on maximising energy efficiency, extending battery range, and implementing ultra-fast charging capabilities.

Modern vehicles rely on an increasing number of high-power modules, from Traction Inverters and On-Board Chargers (OBCs) to Battery Management Systems (BMSs). These components operate under extreme thermal conditions and require superior reliability to ensure vehicle safety and performance.

Aismalibar provides advanced thermal interface materials and insulated metal substrates (IMS) engineered explicitly for highly electrified powertrains. Our solutions ensure optimal heat dissipation in compact electronic modules, enabling the leap toward high-performance electric vehicles and sustainable mobility.

Automotive Lighting

Front Lights

LED technology offers designers unprecedented creative freedom, allowing substrates to be tailored into complex shapes and ultra-compact sizes. Our laminates are specifically engineered to manage the high thermal density generated by high-intensity LEDs concentrated in small areas. By optimising heat dissipation at the board level, Aismalibar ensures long-term system reliability and consistent luminous performance, even in the most demanding architectural and industrial applications.

Rear and Interior Lights

Modern automotive design requires high-performance lighting for both exterior signalling and digital cockpit interfaces. Rear Combination Lamps (RCL) and signal lights operate at high power densities, demanding efficient heat dissipation to prevent LED degradation and ensure safety. Inside the cabin, the integration of digital dashboards leads to a high concentration of electronic components in confined spaces. Aismalibar laminates provide the thermal stability necessary for these densely packed systems, ensuring consistent performance across all interior control modules.  

Automotive Power Train

High-Voltage Power Conversion

Vehicle electrification and power distribution rely on advanced semiconductors, such as IGBTs and SiC MOSFETs, to manage high-voltage power conversion. These components generate intense thermal loads that must be dissipated to ensure system efficiency and prevent power loss. Aismalibar manufactures high-performance substrates specifically engineered for traction inverters and power distribution units (PDU). Our materials provide the superior dielectric strength and thermal conductivity required to ensure the reliability of high-voltage automotive architectures.

On-board Charger (OBC) & Battery Systems

The efficiency of electric vehicles depends on precise thermal control during charging and discharge cycles. High-performance Li-ion battery packs and On-board Chargers (OBCs) generate significant heat, directly affecting charging speed, safety, and battery longevity. Aismalibar provides specialised IMS and CCL laminates designed to mitigate thermal fluctuations in power modules and Battery Management Systems (BMS). Our materials ensure optimal heat dissipation, maximising energy density and extending the operational life of the entire powertrain.

Electric Power Steering (EPS)

Precise steering assistance depends on compact control modules that manage high-current peaks during manoeuvres. Since these systems are often located in high-temperature environments with limited airflow, preventing localised heat spikes is critical for system availability. Aismalibar substrates provide the thermal stability needed to protect power semiconductors from thermal stress. Our materials ensure consistent performance and prevent thermal derating, guaranteeing the reliability of these safety-critical steering systems.

EV battery

Battery Packs

Thermal regulation is critical across all battery operating states, particularly during high-discharge cycles and at elevated states of charge (SoC), where chemical reactivity and thermal stress are most significant. Excessive heat under these conditions accelerates cell degradation and increases safety risks. Aismalibar’s materials combine high dielectric strength with engineered thermal conductivity, enabling efficient and uniform heat dissipation across the battery pack. By reducing localised hotspots, our solutions help prevent thermal runaway and support long-term battery health during fast charging and sustained high-voltage operation.
