Almost all EVs use a pack voltage in the 350-400 volt range. I've heard it said that to get 300 kW or higher charging (from the current Supercharger 120 kW) you'd need to go to 800V or so because the charge cable is thick enough already, so doubling the power would require a really massive charge cable if the voltage stayed the same. However, I just came across this older article about Zero motorcycles. Geeking out on electric motorcycles – a trip to the Zero factory In the article, the engineer states that their 100v pack voltage results in a more efficient motor, more range, lower cost and lower heat. Indeed he goes on to say that he expects EVs to use a lower pack voltage in the future. This is the first time I've heard of this idea. Is the engineer right about the advantages of lower pack voltage?
