Exro announces independent testing of Coil Driver™ technology conducted by AVL, proving power electronics breakthrough that advances electric vehicle performance

Calgary, Alberta (October 7, 2021) – Exro Technologies Inc. (TSX: EXRO, OTCQB: EXROF) (the “Company” or “Exro”), a leading clean technology company that has developed anew class of power electronics for electric motors and batteries, announced today its first independent third-party testing of its Coil Driver™ technology that was conducted by AVL, the world’s largest independent company for development, simulation and testing of powertrain systems and software for the automotive industry.

‍

Exro partnered with AVL because of its deep knowledge of powertrain components and systems and its experience working with top automakers to ensure their systems meet design expectations and targets. AVL has been a trusted source of third-party testing for the automotive industry for over fifty years and its mechanical testing for the verification of powertrain systems carries significant weight among Exro’s customer base.

‍

A series of tests were performed on an electric motor dynamometer (“dyno”) with the Coil Driver™ to demonstrate coil switching performance at various speeds and under different conditions. Coil switching is a term referring to the switching of electric motor configurations while in operation to optimize speed and torque, similar to how a gearbox changes the gears for a combustion vehicle as it changes speed.

‍

Results from AVL’s testing demonstrated the Coil Driverᵀᴹ successfully switches coil configurations while in operation on an electric motor seamlessly. Exro is the first to perform coil switching through the electric motor controller, which is essential for scale, and important in electric vehicles to reduce costs while improving performance. These results prove Exro has successfully combined two traditionally separate formats of power electronics, the series mode for low-speed torque and parallel mode for high-speed efficiency, for the first time. This means that the Coil Driver will be able to deliver more performance out of the same motor with multiple torque profiles.

‍

This successful third-party testing of Coil Driver technology enables the Company to accelerate commercialization and provides the validation customers need to confidently integrate the technology into various applications at scale. The full test report detailing the test procedure and results performed by AVL in October 2021 is available here:
