I highly recommend Wired's article about GM's long-term bet in developing the Bolt. It talks about many ways that developing an electric car is not just a matter of adding batteries to your existing expertise in car manufacturing. e.g.: > Nearly everything changes when you opt for a fundamentally different power train, so GM’s greatest advantage—more than a century of experience building cars—was all but moot. Car structure was different, since they were building around a battery, not an engine. The brakes, steering, and air conditioner were powered differently. New systems, from electromagnetics for the motors to onboard and off-board charging, each came with its own learning curve. The engineers didn’t have established tests to follow. Just turning on the car required finding the perfect sequence of electrical signals from more than a dozen modules. “Oh my God, it took us forever to get the first Volt to start,” Fletcher says. https://www.wired.com/2016/01/gm-electric-car-chevy-bolt-mary-barra/ https://www.wired.com/2016/01/gm-electric-car-chevy-bolt-mar...
