Interface Helps to Power the Electric Vehicle Market Forward

Any time innovation is introduced into the market, it takes many years to iterate and realize the full potential of the technology. In today’s automotive marketplace, electric vehicles (EV) are reaching a point where the technology and capabilities are fully realized and is primed for an outbreak on mass scale. In fact, a recent IEA report found that more than 10 million cars on the road in 2020 were electric, estimated to be 2% of the market.

There are currently 370 models of electric vehicles sold today, with the number growing. To facilitate the further growth of the EV market, Interface continues to play a pivotal role in supplying force and torque test and measurement systems that meet the demands for superior testing requirements of all components used to make these vehicles. The automotive market, and especially EVs, are subjected to extremely strict regulations. Therefore, test and measurement are critical for every part for safety, reliability, durability, and overall vehicle performance.

Interface saw the rise in the electric vehicle market long before is the exponential adoption and growth and started early in investing in the development of force measurement technologies designed specifically to support testing of EVs. Our products we’re already well-known within the automotive industry because of our ability to deliver superior quality and high accuracy solutions that auto manufacturers and testing labs rely upon.

One of the most important developments in our lineup of EV compatible testing equipment was the introduction of AxialTQ™ torque transducer system in 2018. The AxialTQ system was engineered in direct collaboration with end-users who shared operational priorities, user interface, design, features, real-world field issues and more. The AxialTQ torque measurement system redefines the torque transducer category in terms a crash-proof design for maximum reliability, versatile model for application flexibility, simultaneous analog and digital outputs, real-time control and data collection and interchangeable stators and output modules that minimize parts inventory. You can see it in action in this video, AxialTQ Engine Dynamometer Application Note.

The rotor sensing element and electronics are the heart of the system which will be offered in 8 torque capacities in 5 DIN sizes. With the flexible capability of stator and output module mounting, the AxialTQ system offers vast configurations capabilities to meet any application need, especially for testing of EV motors. Watch the latest webinar, The Latest Spin on AxialTQ, to learn more about this dynamic auto testing transducer.

Torque Measurement for Electric Vehicles

When an electric vehicle manufacturer needed a torque measurement system for their electric vehicle, they contacted us to inquire about a solution designed for the unique needs of EV motors. These motors run at significantly higher rotational speeds than their internal combustion engine (ICE) counterparts and have much higher power densities due to the small size and light weight. The preferred system would be used to test the torque and speed of their electric motors to achieve and ensure optimum instant peak torque performance.

Interface provided its AxialTQ Wireless Rotary Torque Transducer to provide the highest quality torque measurement. This product was delivered with the AxialTQ Output Module and the provided AxialTQ Assistant Software, that is installed on a test bench. This allows data results to be calculated and collected in real-time. Using AxialTQ, the customer ran tests to sense the electric vehicle’s motor with high accuracy. It both measured and calculated the electric vehicles torque and rotational speed (RPM), while collecting data. Results are then be reviewed on the customer’s PC or laptop with the included AxialTQ Assistant Software. Using this solution, the customer was able to achieve their required instant peak torque.

This is just one of the many test and measurement solutions Interface provides to automotive manufacturers and makers of electric vehicles components.  Interface will be showcasing additional products used for auto testing at the next Automotive Test Expo.  You can see a highlight of some of these products in this highlight video of popular Interface automotive testing products.
