![]() Why EV batteries could be reusedĪfter 8 to 12 years in a vehicle, the lithium batteries used in EVs are likely to retain more than two thirds of their usable energy storage. Assuming a conservative capacity for each of these batteries (25 kWh), this amounts to over 1 GWh/year of available storage in the Golden State. For context, this is over 200 times total energy storage installed in the US in 2018 (~780 MWh).Ĭalifornia is the largest market for EVs in the US and by 2027, an estimated 45,000 EV batteries will be retired from the state. Forecasts from academic studies and industry reports estimate a range of 112-275 GWh per year of second-life batteries becoming available by 2030 globally. The market for second-life batteriesĪs the market for electric vehicles grows, so too will the supply of second-life batteries. ![]() This blog summarizes a brief white paper I helped developed with researchers from the University of California Davis for the group. In this blog, I describe current industry landscape and explain the potential use cases for second-life EV batteries. Today, I’ll be providing testimony to the California Lithium Battery Recycling Advisory Group regarding the reuse of EV batteries the advisory group’s goal is to make recommendations to ensure 100% of EV batteries sold in California are reused or recycled. But in order to enable widespread reuse of EV batteries, policy will play an important role in reducing barriers and ensuring responsible, equitable, and sustainable practices. Given the growing market for EVs, second-life batteries could also represent a market of low-cost storage for utilities and electricity consumers. ![]() The economic potential for battery reuse, or second-life, could help to further decrease the upfront costs of EV batteries and increase the value of a used EV. Before batteries are recycled to recover critical energy materials, reusing batteries in secondary applications is a promising strategy. Many of the batteries coming off the road are being used to evaluate a range of options for reuse and recycling. Today, EVs are a still a small piece of the automotive market. When an electric vehicle (EV) comes off the road, what happens to the vehicle battery? The fate of the lithium ion batteries in electric vehicles is an important question for manufacturers, policy makers, and EV owners alike. ![]()
