THE EVOLUTION OF THERMAL SHIELDS IN THE AUTOMOTIVE INDUSTRY: FROM INTERNAL COMBUSTION TO ELECTRIFICATION

The transformation from internal combustion engines (ICE) to electric vehicles (EV) not only affects the powertrain but also thermal management. Thermal shields, which protect components from excessive heat, have evolved from simple metal structures in ICE vehicles to advanced multi-layer solutions in EVs. These advancements must ensure the performance, safety, and efficiency of modern powertrains.

Thermal Shields in Internal Combustion Engines

In ICE vehicles, thermal shields primarily protect components such as the engine, exhaust systems, and catalytic converters from heat. Typically made of materials like aluminum or stainless steel, these shields reflect or dissipate heat from sensitive areas. Although effective in traditional vehicles, these designs were not suitable for the growing demands of electric mobility, especially considering the high heat generated by EV batteries.

Thermal Management in Electric Vehicles

Electric vehicles require new approaches to thermal management due to the high heat generated by lithium-ion batteries. As EVs charge and discharge, the battery temperature can rise significantly, which affects performance and safety. Proper thermal management is crucial to maintain battery efficiency, prolong its life, and prevent issues such as thermal runaway.

Unlike ICE vehicles, where heat dissipation is mostly passive, EVs rely on active cooling systems, often using composite materials, multi-layer shields, and liquid cooling solutions to maintain optimal battery temperature. These advanced systems are also designed to be lightweight, improving the energy efficiency of EVs and increasing their range.
