电动车包括特斯拉是用PWM控制速度；会有低频辐射

It is very easy to control and very tolerant of input conditions. It takes a PWM signal anywhere from 35 to 400 hz. Control range is from 5% (max speed) to 85% (min speed) duty cycle.

结论是还算安全？

车里的大功率inverter在把电池的dc能量转化为驱动电机的ac能量时产生一点低频电磁辐射，inverter有金属外壳

结论是EV的辐射对人体危害极小？

我还是觉得要小心。
