Exro Validates Intelligent Battery Technology for Second Life Applications


Reading time ( words)

Exro Technologies Inc., a leading clean technology company which has developed a new class of power electronics for electric motors and batteries, is pleased to announce that it has completed the technology validation on its Battery Control System (BCS) – formerly known as the intelligent battery management system.

The BCS can expand the capabilities of batteries by enabling a greater depth of control on the cells. The cells remaining in a battery at the end of first life can be optimized to rejuvenate the same battery into a new second life. Exro can establish a greater depth of control on battery cells because the same principles that govern coil groupings in electric motors can also apply to managing cells in a battery.

As more electric vehicle batteries reach end of first life, there is a growing number of batteries that can be utilized for second life energy storage. The BCS can help Exro to lead the rapidly accelerating energy storage markets. Second life energy storage is a dynamic growth market with CAGR projections of 23.1% through 2030.

Simulations in the lab have demonstrated the principles required for optimized second life operations. The system is able to regulate grid current, charge and discharge at cell level, and manage cells with different states of charge. Exro will move forward to demonstrating the Battery Control System in operating applications in 2021.

"Now it's just about scaling this up", said Eric Hustedt, Chief Engineer of Exro. "We've confirmed the operational principles with our simulations and are very excited about the potential for this system in new environments."

"This is a great example of the synergy we have with our advanced control technology in multiple markets", commented Sue Ozdemir, Chief Executive Officer of Exro. "This technology validation is a great first step in our path to advancing battery control in energy storage applications."
