Some people below saying batteries are a commodity: Battery cells are a commodity, but the battery packs where thousands of battery cells are combined with monitoring, heating and cooling systems are not. They're a very complicated bit of kit. Building an EV is a trivial commodity This isn't true either, its all about efficiency, if your drivetrain is not efficient then you waste money and weight on a bigger battery pack than is necessary. In summary: EV batteries are not simple (battery packs are actually very complicated). EVs are not simple either - the drivetrain, braking/regen systems, power management, heating are all very hard to get right. If you dont get the right performance/efficiency balance, your car is heavier and more expensive for a given range than it should be.
