在安全与可靠性测试层面，第二代刀片电池进行了多项超出现行行业标准的极限验证。该电池在完成 500次闪充循环后，叠加进行了两轮边闪充边针刺试验，结果均显示无烟、无明火。在针对热失控的热 扩散试验中，新国标要求触发1节电池短路，而第二代刀片电池挑战了同时触发4节电池短路，最终电池 包未发生起火或爆炸。此外，官方数据显示其底部撞击试验标准达到新国标的10倍，且电池质保容量保 持率提升了2.5%。 针对新能源汽车在低温环境下的补能效率问题，比亚迪展示了该电池在极端条件下的测试结果。在零下 30摄氏度的低温舱内冷冻24小时后，第二代刀片电池电量从20%充至97%用时不到12分钟，相较常温环 境仅增加3分钟。在续航方面，该电池的能量密度较第一代提升5%。首批搭载该电池的纯电车型腾势 Z9GT与仰望U7，其纯电续航里程均超过1000公里（最高达1036km），在汽车之家组织的实测挑战中， 完成了闪充9分钟环绕海南岛的测试。 凤凰网科技讯 3月5日，比亚迪（002594）正式发布第二代刀片电池，公布了其在充电速率、极寒环境 表现及安全测试等维度的核心数据。根据官方披露的信息，新一代电池的闪充技术可实现电量从10%充 至70% ...
