> <i>A typical long-range electric vehicle today comes with a 120 kilowatt-hour battery pack that takes an hour to recharge.</i><p>120 kWh is a large pack that's not typical of EVs at the moment. 75 kWh is more typical.<p>It would be nice if most passenger EVs had even a 150 kWh pack. That would mean longer and very practical range but it'd make the cars more expensive. Better battery chemistries are needed for cheaper batteries with higher energy density.<p>Nio will introduce a 150 kWh pack soon alongside their existing 75 and 100 kWh packs. Because Nio's packs are swappable the new pack can be swapped in 6 minutes.
