Quite a few of the newer EVs have 800 V batteries to make fast charging more practical with cables light enough to be handled by ordinary humans. You can make an electric motor run on pretty much any combination of voltage and current. You just have to make the appropriate trade-offs in insulation, conductor cross section, etc. ABB (my former employer) makes motors that run on 13.8 kV with a power of up to 29 MW.
