GM cuts the cord with a new wireless battery pack management system
You don’t think about it often, but wiring is hefty. It’s one of the heaviest subsystems on a car, weighing in around 150 pounds in today’s more well-equipped models, though a simpler economy car car may have at least 50 pounds of copper wire. As the industry moves toward an “all-electric” future, finding ways to manage this weight will become vital as we pursue increasingly lighter, more efficient vehicles. While wiring schemes are becoming simpler thanks to technologies like CAN-Bus (which can reduce a complicated wiring harness down into a single pair of data lines), what if we just got rid of the wiring itself whenever possible? That’s what GM is planning with Analog Devices, a supplier that specializes in charging hardware for mobile devices, among other things.
