电芯倒置技术极端情况下让电池向下排气

车质网10-26

日前，在第二十三届中国汽车工程学会上，小米汽车电池系统负责人姚定在谈到CTB电池倒置技术时表示，这种设计可以在极端恶劣情况下让电池向下排气（释放能量），从而最大程度保证乘员舱安全。雷军曾在小米SU7的技术发布会上详细讲解了电芯倒置设计，在碰撞或热失控发生时，火焰或冲击力会向下释放，而非朝向车内乘员，为救援争取时间。为了解决电芯倒置后重力对电解液的影响，小米还与宁德时代专门研发了特殊电解液。小米汽车...

Ultra电池包底部使用的防弹涂层被广泛应用于军事装备和航空航天器件，例如装甲车的防雷板、军车铠甲、防弹头盔等，具有抗爆防弹效果。在应用这种材料后，小米SU7 Ultra的电池包底部较传统电池包底部防护材料的耐撕裂性能提升10倍、耐穿刺性能提升13倍、耐刮擦性能提升10倍、附着力提升10倍，能够显著提高小米SU7 Ultra电池包的耐刮擦和耐穿刺性能。为了直观展示这种材料的效果，雷军还专门发布了一个视频，展示了一个趣味测试：将防弹涂层涂在西瓜上，从6楼高处扔下，西瓜并未摔破。","news_type":1,"symbols_score_info":{"81810":0.6,"HXXD.SI":0.6,"MIUmain":0.6,"01810":0.9}},"isVote":1,"likeStatus":false,"favoriteStatus":false,"reportStatus":false,"tweetType":1,"langContent":"CN"}],"hasMoreComments":true,"newsSizeData":{"likeSize":0,"commentSize":1,"repostSize":1,"favoriteSize":0,"likeStatus":false,"favoriteStatus":false},"isCrawlerRequest":true}
