High-voltage EV battery packs: benefits and challenges. More voltage

As with most things in engineering, arbitrarily increasing the pack voltage isn''t unequivocally a good thing, and that''s even without invoking a reductio ad absurdum argument (e.g. if 1 kV is better than 100 V, then 10 kV is better than 1 kV, etc.). Still, there are some benefits to increasing the pack voltage, and the most obvious is that less cross-sectional area in
