# YU7 在电池包防护方面做了哪些提升？小米回应

> 小米汽车在 7 月 5 日的问答中表示，YU7 全系电池包在安全防护方面进行了多项提升，硬核物理防护提升至 16 层及以上。具体措施包括：在底盘前部新增 1500MPa 强度的防刮底横梁，构建三重防线，增强电池包的安全性。电池包前缘新增防刮底结构，能有效吸能；底部采用防弹涂层，减少刮蹭对电池包的损伤。

7 月 5 日晚，小米汽车在最新一期答网友问中表示，小米 YU7 全系电池包在安全防护上采取了多项措施，硬核物理防护提升至 16 层及以上。小米汽车介绍：“比如在底部防护方面，我们构建了三重防线。首先，我们在底盘前部新增了强度达到 1500MPa 的防刮底横梁，能在行驶过程中先抵挡掉路面石块的撞击，为电池包提供了第一道防线；其次，我们在电池包前缘新增了防刮底结构，如在行驶中受到碰撞能够有效吸能，构成了电池包的第二道防线；同时小米 YU7 的电池包底部还升级采用了小米 SU7 Ultra 同款「防弹涂层」，当车辆底部遭遇刮蹭时，有效地吸收冲击能量，大大减少底部刮蹭对电池包造成的损伤，构筑起了电池包的第三道坚固防线。”
