Aiming to Build Battery Ecosystem, Toyota & Mazda Start Tests of Energy Storage System Using Electrified Vehicle Batteries - CleanTechnica

Toyota Motor Corporation and Mazda Motor Corporation have initiated field tests of Toyota’s Sweep Energy Storage System at Mazda’s Hiroshima Plant in Japan. This system connects the power infrastructure at Mazda’s headquarters—the only automaker-operated power generation system in Japan—with Toyota’s energy management system that utilizes batteries from electrified vehicles. The collaboration aims to verify stable, high-quality, and efficient charging and discharging processes by integrating different battery types and conditions. The primary goal of these tests is to support the regulation of power supply and demand from renewable energy sources, which are inherently variable due to weather and time of day, thereby contributing to carbon neutrality efforts. This initiative is part of a broader industry effort led by the Japan Automobile Manufacturers Association to build a sustainable battery ecosystem. This ecosystem focuses on the stable procurement of critical resources, resilient supply chains, and the sustainable reuse of batteries, including those from electrified vehicles, within Japan. Both companies plan to continue advancing this multipathway approach to enhance carbon neutrality and strengthen the automotive industry's
