Interface has been a longtime provider of force measurement solutions that help engineers develop the technology of tomorrow. One of our main areas of expertise during our 50 plus years in business has been in solutions for the automotive industry.
Interface has helped to revolutionize design and efficiency in this industry using our high accuracy test and measurement solutions. With the increased need for sustainable electric vehicles, we have set our sights on advancing this high-growth area in automotive.
“Less than 5 percent of vehicles sold in 2016 were equipped with EV power trains. Major OEMs have announced that they’re aiming to bring that number above 50 percent by 2021.” McKinsey Quarterly, February 2019
Electric vehicle design and manufacturing requires a precise level of accuracy in order to improve energy efficiency, minimize weight and maximize vehicle range. Battery technology has only come so far; therefore, maximizing power output is the key to improving vehicle design. To achieve this, test and measurement solutions need to be as accurate as possible.
Interface provides high accuracy torque transducers, load cells, load washers and more for two areas of electric vehicle testing: laboratory testing to optimize system performance and production testing to ensure product quality.
Interface’s Role in Vehicle Testing
In laboratory testing, Interface force and torque measurement products are used to achieve high-efficiency in component and system designs. While electric vehicle designs are already very efficient, minimal design adjustments can make a difference to increase total range from a single charge. Making small incremental changes in efficiency, therefore, requires very accurate measurement capability.
Applications of our products in the laboratory environment include maximizing the system performance of electric vehicle drivetrain components, such as motors and gearboxes. As well as performance in auxiliary systems, such as air conditioning compressors and motors, power steering motors, and even brake systems. Accurately measuring the force of dynamic systems like suspension components allow the designer to minimize weight to improve overall vehicle range and performance.
Once the components are moved into the vehicle production phase, Interface solutions are used to ensure the product has been built per the design. Our products can be used to measure the steady state, as well as the dynamic performance of components and systems. Using measurement systems they can trust gives customers the confidence that the components and systems meet the performance and dependability expected for the vehicle design.
The key to electric vehicle design is balancing the relationship between efficiency, performance, and cost. The further we can make electric vehicles go on a single charge, the more attractive these vehicles become for mass markets.
Optimized efficiency requires the most accurate measurements available to our customers and this is where Interface excels. Jake Shaffer, Senior Product Manager
In October 2018, Interface released AxialTQ, specifically designed to help in the transforming vehicle market, including electric and autonomous vehicles. You can read about AxialTQ and view this revolutionary next-generation torque measurement system in action here:
