In this context, researchers Guttorm Asse, Chris Musso and Dennis Schweidhelm agreed that the architecture of tomorrow’s vehicles is what is defined today, giving chemical companies a small opportunity to set standards for material applications. in the years to come. Window C is offered.
According to the report prepared by three experts, while chemicals in the automotive industry have traditionally been considered on a unit cost basis, with suppliers barely retaining value throughout the program lifecycle, most Savvy auto parts manufacturers and tier suppliers are now moving towards a system value approach. These players believe that physical solutions can bring tremendous value in reducing costs and improving the reliability of expensive parts such as batteries, power electronics and electric motors.
The report states that a typical BEV’s powertrain (battery, inverter and electric motor) costs more than $10,000, four times more than the same parts in a traditional combustion engine car. Therefore, the electric vehicle system must reduce its cost for more popular and widespread adoption.
In this context, leading OEMs have found that using the right thermal and insulating materials in powertrains can result in a significant increase in system efficiency and reduction in warranty costs, which together can be worth several years. . Hundreds of dollars per vehicle. These savings make it much easier for OEMs to invest in these enabling materials.
For example, transitioning from silicon oxide (Si) power modules to silicon carbide (SiC) power modules in the inverter can result in system savings on the order of $200 per vehicle. This is due to the higher energy efficiency of the semiconductor (which reduces battery costs) and a more optimal cooling profile (which reduces thermal management costs), even though SiC costs more than its Si counterparts.
Estimated competitive in the final price of the product, taking into account batteries, systems and thermal products, its total cost will increase from the current USD 10,300 to USD 8,200 in 2025, reaching USD 7,100 in 2030. Ira,
At the same time, academic work has highlighted that hardware innovations that reduce system costs can deliver tremendous value and are expected to represent a $20 billion market by 2030 in the efficiency-related industry. energy. , thermal management and battery life, not to mention cell chemistry.
“The electric vehicle industry is making a significant shift towards higher temperature, more expensive and more efficient inverter technology, which will require better thermal and insulation materials,” he said.
It’s no secret that battery costs need to come down significantly for electric vehicles to be profitable, and that battery safety is paramount. According to McKinsey researchers, while most of the conversation seems to focus on the chemistry and balance between supply and demand of battery cell materials, many device manufacturers have already recognized that plastics , silicon, asbestos (insulation) and other thermal materials can be designed. To greatly reduce the system cost of electric cars.
