面向高压逆变控制固件的故障自愈式双分区（A/B Partition）原子级安全烧录
向负责高压充电与逆变回路的专用数字信号处理器（DSP）安全下发附带密码学签名的固件镜像，具备物理掉电自愈与原子级零延迟回滚保障。
下电休眠态毫秒级原子切换
新固件镜像在充电结束下电间隙完成完整硬件哈希验签，并在接触器完全断开后实现双分区零风险秒级倒换。
- Zero-brick guarantee with dual-bank hardware flash mirrors.
- Sub-second rollback if power stage diagnostics fail self-test.
- Differential compression reducing update payload sizes by 80%.
- Full UNECE R156 software update compliance audit trails.
