Amid the thriving new energy vehicle market, ultra-fast charging technology has garnered significant attention. This year, megawatt fast charging products are poised to enter the market, catering to the growing demand for faster charging speeds. However, CATL's Chief Technology Officer (CTO), Gao Huan, recently cautioned that the relentless pursuit of ultra-fast charging can potentially undermine the reliability, longevity, and safety of battery products. Some companies, eager to seize market share, are promoting their products based solely on laboratory parameters, without fully addressing the long-term repercussions of fast charging on battery integrity. Gao Huan underscores the importance of a holistic approach in evaluating battery performance, emphasizing that faster charging speeds for electric vehicles do not inherently equate to better overall performance. Instead, a delicate balance must be struck between charging speed and battery efficacy.
