2022款Model 3、Model Y新变化：全面换用AMD锐龙芯片和12V锂电瓶

在上海工厂的国产Model 3/Y（含性能版）的中控车机陆续换用AMD锐龙芯片后，美国本土生产和交付的2022款Model 3/Y也开始做类似调整了。

这套名为MCU 3的新中控平台采用12nm Zen+/Navi 23构成的4核嵌入式芯片，早先基于国产Model Y性能版的测试发现，对比上一代车机Intel A3950，车机打开、加载软件的速度均有数倍提升。

除了锐龙加入，另一个变化是车载电瓶不再是12V铅酸蓄电池，而升级为锂电池。

此前，特斯拉车主饱受12V铅酸电瓶故障的困扰，换用锂电系统后，希望能有所改善。据了解，锂电瓶比铅酸电瓶大幅减重，同时更换周期（寿命）也从2年提升到4年。
