Battery Operational History: Robert and Eric interview Shahab Shokrzadeh who founded a startup company focused on battery repurposing. His venture is base of the work he did on his PhD where he modeled how EV batteries can be used to support wind and solar energy after they are no longer needed in an electric vehicle. He demonstrated a circular economy where batteries can have a second life to support the energy needed to power electric vehicles. In this way charging of electric vehicles using wind and solar does not impact utilities. (repeat)

This episode of Dr. Renewable features a conversation with Shahab, a specialist in battery technology. The discussion centers around the evolving role of batteries, particularly in electric vehicles, and the importance of managing their lifecycle effectively. Shahab explains that batteries are no longer just energy storage devices but are at the center of a convergence between the transportation and energy sectors. This integration presents both opportunities and challenges, primarily due to the current energy system's limited capacity to support widespread electric vehicle adoption.Shahab emphasizes the need for a holistic approach to battery management, from material sourcing and manufacturing to in-vehicle use, repurposing, and recycling. He introduces the concept of batteries as "energy assets," requiring a comprehensive understanding of their history and usage. To achieve this, he and his team have developed two key solutions: a globally unique, tamper-proof digital identification for each battery (Battery Identity Module or BIM), and a "battery life intelligence" system. The BIM tracks the battery's journey from its origin to its eventual end-of-life, while the life intelligence system captures both static data (materials, origin, environmental footprint) and dynamic data (real-time status, usage patterns).The conversation addresses the "throwaway battery" myth, explaining that electric vehicle batteries typically have a lifespan of 8-10 years in a car, after which they still retain about 80% of their capacity and can be repurposed for stationary applications for another 15-20 years. This second life extends the battery's value and reduces the overall cost of energy storage. Shahab discusses the complexities of managing these retired batteries, including ownership, testing, and deployment in second-life applications like supporting wind farms. He highlights the economic potential of battery repurpose, aiming to reduce the cost of energy storage to a fraction of current electricity prices.Shahab acknowledges the resistance to these ideas, particularly from automotive manufacturers who may prefer to control the entire battery lifecycle themselves. However, he argues that a common language and shared data are essential for a functional battery ecosystem, especially as the number of electric vehicles increases. He stresses the need for collaboration and standardization to avoid a fragmented and inefficient system. He notes that the lack of electric vehicles currently masks this issue but will become glaring soon.The conversation touches on the rapid advancements in battery technology, with new chemistries and improved performance constantly emerging. Shahab emphasizes the importance of understanding the specific characteristics of each battery type to determine its suitability for different applications. He also mentions the development of AI and other algorithms to better understand battery lifecycles, though he suggests their approach focuses on snapshots of battery data rather than constant real-time streaming. The episode concludes with a discussion about the future of battery technology and the potential for significant advancements in the coming years, with the hope that Shahab will return to providing further updates on his work.In summary, Shahab is working at developing a technology to be able to interrogate a battery and see it history. Very much like medical records for a patient, this information would reveal the battery history so that it can be used most appropriately after it is no longer needed in an electric vehicle. By repurposing batteries before they are eventually recycled, batteries can contribute not only to provide sustainable transportation, but also support intermediate wind and solar. Shahab is part of the next generation of professional developing solutions to address climate change.This episode of Dr. Renewable features a conversation with Shahab, a specialist in battery technology.
