Exro to Repurpose evTS Electric Vehicle Batteries into Second-Life Energy Storage System

Calgary, Alberta (December 16, 2021) – Exro Technologies Inc. (TSX:EXRO, OTCQB: EXROF) (the “Company” or “Exro”), a leading clean technology company that has developed a new class of power electronics for electric motors and batteries, announced today a development partnership with evTransportation Services Inc. ("evTS"), a Boston-based specialty electric vehicle manufacturer, to repurpose batteries from evTS’ pure-electric FireFly ESV commercial utility vehicle for second-life battery energy storage applications. Exro's Energy Storage System (ESS), equipped with its Battery Control System™ (BCS) technology, can extend the retired electric vehicle (EV)batteries into a second life and demonstrates Exro’s ability to reduce both carbon emissions and rare earth material consumption.

evTS' flagship product, the FireFly® ESV, is a purpose-built, lightweight commercial utility vehicle that is both street-legal and highway-capable. The FireFly ESV is built with safe Lithium Iron Phosphate (LFP) battery technology and an advanced battery management system to improve charging and energy efficiency with up to 10 years of useful life. At the end of its first life, the FireFly ESV LFP battery may still have remaining battery capacity, but no longer has the efficiency required for use in EV applications. These cells are ideal for a test bench demonstration of Exro’s next-generation 90kW ESS, which allows retired EV battery cells to be efficiently reused for stationary second-life energy storage applications.

“By partnering with Exro, we hope to further bolster the environmentally friendly profile of our vehicles – providing our batteries with a second-life as an energy storage system,” said Greg Horne, Chief Technology Officer at evTS. “Our FireFly ESV will not only help to drive forward the future of last-mile delivery, as through our partnership with Exro, we will help eliminate battery disposal issues and contribute to the circular economy.”

Exro’s BCS is an innovative battery management inverter combined with advanced cell control software that can expand the capabilities of batteries by enabling a great depth of control on the cells. In this case, Exro will pilot a test bench demonstrator that integrates its BCS technology with the FireFly ESV LFP batteries to repurpose the retired battery cells and extend them into a second life in an ESS application. LFP batteries are a growing standard in electric mobility applications because of their safety and reliability advantages while improving on access to raw materials. The test bench demonstrator results are expected inQ3 of 2022.

“As electric vehicle batteries reach end of first life, we know there is a growing market for LFP batteries that can be repurposed for second-life energy storage applications,” said Sue Ozdemir, CEO of Exro. “EV manufacturers can experience significant cost savings by reviving and utilizing second-life batteries and we’re excited to partner with evTS on a pilot project to extend the life of their FireFly ESV batteries, while supporting their sustainable electric vehicle repurposing processes.”

As Exro and development partner evTS collaborate on the second-life ESS solution, the teams are also evaluating how Exro’s intelligent control technology can optimize the FireFly ESV for first-life applications.
