Where have we seen 350 volts before?
What are some common battery voltages used on EV and hybrids? Well 270 to 350 DC volts of course.
Common normal single phase voltage for a lower voltage non 480 volt drive is 208v and 240vac AC. Which should make between 290 and 350vdc.
It's like they just repurposed and slightly reengineered existing industrial drive designs for automotive use.

Not repurposed... common sense would indicate that charging of a 350v battery at high current is much easier when the required voltage is close to the D.C. rectified value of the mains supply. Lowering cost and improving overall efficiency.
