It’s the technological heart of what promises to be the most significant vehicle General Motors has produced in decades: the first truly mass-market all-electric car. This dark monolith is the thing I’ve come to Detroit to see. It’s 3 feet wide and 6 feet long and has dozens of plastic-tipped, copper-colored wires protruding from its surface in a sprawling mess of metallic spaghetti. Sitting on top is a smooth black alien-looking thing, about the size and shape of a very thick rectangular kitchen tabletop.

Near the end of the room, he finally stops us in front of a large industrial dolly. The tests run 24 hours a day and in silence, generating terabytes of data.īut Nitz hasn’t brought me here just to show me a bunch of blue boxes. People drive in cities, in the suburbs, and on the highway. The enclosed batteries-not the familiar 40-pound bricks that need a jump start from time to time, but 1,000-pound behemoths built to power an entire car-are hooked up to testing equipment that charges and discharges them in patterns designed to mimic the ways

So inside each blue chamber, GM has created a virtual Yukon winter or Florida summer or Arizona spring. Battery chemistry is fiendishly sensitive to temperature and humidity, he explains, and electric cars have to hold up in every kind of weather. They’re climate simulators, Nitz says as we file past row after row of them. They look a little like walk-in freezers, which isn’t too far off. In place of all the old V-8s, a grid of 18 massive cobalt blue boxes, each 10 feet high and 8 feet wide, now dominate the lab.
