What are the Main Factors Influencing the Growth of the Acoustic and Thermal Insulation Market?
Following the expected depletion of the world’s oil reserves and growing worries about air pollution in many cities, automobile manufacturers are developing electric vehicles (EVs) as economical, dependable, and safe alternatives to internal combustion (IC) engine vehicles.
Furthermore, regulation in many areas of the world to reduce car exhaust emissions has prompted electric vehicle manufacturers to build battery-electric or completely electric automobiles (BEVs). Hybrid electric vehicles (HEVs) and plug-in hybrid electric vehicles (PHEVs) are two other types of EVs.
The changes in a vehicle’s noise, vibration, and harshness (NVH) qualities have been identified as a serious concern with the introduction of EVs. EVs are quieter than IC engine cars, owing to the lack of noise generated by the gasoline engine and transmission systems.
As a result, EVs may travel without making any noise or polluting the air. In reality, some regulatory agencies, like the National Highway Traffic Safety Administration (NHTSA) and the European Parliament, have established legislation requiring electric cars to emit artificial noises to notify walkers while going at moderate speeds.
Electric vehicle sales have gradually gained traction in several regional markets, but the market is still insignificant in comparison to the global internal-combustion engine-based vehicle industry. Various studies imply that electric vehicles will ultimately dominate the automotive industry and many existing vehicle manufacturers.
According to BIS Research, the global acoustic and thermal insulation market for electric vehicles was valued at $134.4 million in 2020 and is projected to reach $1,108.4 million by 2031, registering a CAGR of 20.45% during the period 2021–2031.
The global acoustic and thermal insulation market for electric cars are divided into three primary categories: hybrid electric vehicles (HEVs), plug-in hybrid electric vehicles (PHEVs), and battery electric vehicles (BEVs). These vehicle types can be found in the form of passenger automobiles as well as commercial vehicles.
Factors that can aid Acoustic and Thermal Insulation Market
· Better driving experience: There is a strong need for improved comfort and convenience within a vehicle’s interior. Many customers want to be able to customize and maximize their automobile experiences.
There is a need to build a vibroacoustic environment that would be appropriate for offering increased vehicle quality, making electric vehicles more acceptable to new purchasers.
The absence of internal combustion (IC) engines in electric cars causes a variety of buzz, squeak, and rattle (BSR) issues. These sounds are likely to cause an inappropriate driving experience, as the disruptions are often more perceptible in electric vehicles than IC engine vehicles due to EVs’ lack of sound production.
Electric vehicles are known to be high-tech engines; consequently, the sound field around the vehicle should be high-tech as well. Noises from the vehicle’s interior and exterior elements must be designed in such a manner that they do not obstruct the driver’s experience.
Exterior sounds such as traffic, road, and wind noises must be avoided while driving an electric car. As a result, delivering an ambient interior sound quality becomes a priority for electric car makers, and attempts to match these needs are projected to drive the industry.
· Reduced ancillary noise: There is a widespread belief that the primary source of noise in a standard car is the IC engine; hence, EVs are quieter owing to the absence of an IC engine.
Other components of a conventional vehicle, on the other hand, emit strong sounds that are generally disguised by the engine noise; as a result, secondary noises in an EV are expected to be more noticeable.
Sounds from the road and tires, wind and vehicle exterior noises, and noises from the vehicle’s heating, ventilation, and air conditioning (HVAC) system become more noticeable in an electric car, causing additional issues for acoustic insulation.
Transmission sounds from the electric motor and battery, vehicle inverter, switch-mode converter, vehicle gearbox, and auxiliary system noises, in addition to these, provide an additional challenge to reducing noise in electric vehicles. To provide smoother driving experiences, these noises must be disguised inside an electric vehicle using acoustic insulation materials.
· Thermal insulation in EV batteries to maintain chemical reactions: EV batteries enable electric vehicles to run for a longer period at a single charge. An enhanced driving range on a single charge is predicted to increase the acceptability of electric vehicles in the public sphere, resulting in higher vehicle sales.
The majority of these vehicles use lithium-ion batteries, which have dominated the market for electric vehicle batteries. These lithium-ion batteries create heat, and as the battery set components grow more layered to give a higher range of performance, the batteries release more heat.
There are also numerous sensitive electrical components near the electric battery components, and the battery system’s functioning temperature must be controlled within a range. Thermal insulation with mica or mica-based materials is necessary to preserve and stabilize a battery system across a wide temperature range while also increasing the range of an electric vehicle.
To conclude, enhanced thermal insulation is required to safeguard the battery pack in adverse weather conditions, as the battery might lose efficiency if its temperature is not maintained while driving. The continuous demand for innovation, lightweight, and efficient insulation materials for electric vehicles is driving the worldwide acoustic and thermal insulation market for electric vehicles to grow.
