At the "10th International Summit on Power Battery Applications (CBIS2025)", Liu Jincheng, the Chairman of EVE Energy, emphasized that the future progression of power batteries hinges on overcoming two primary challenges. The first is the full-lifecycle cost. At present, battery expenses constitute a substantial portion of the overall cost of electric vehicles, rendering cost reduction a pivotal factor for the industry's long-term viability. The second challenge pertains to battery performance in extremely cold climates. Battery efficacy drops markedly in low-temperature conditions, thereby impacting driving range and utilization efficiency. Looking ahead, power batteries should be seamlessly integrated into distributed energy systems, allowing electric vehicles to serve as "mobile energy banks" and infusing fresh impetus into the green energy transition via vehicle-to-grid interaction technologies.
