End of orange wires everywhere

IEEE Spectrum has been looking under the bonnet of General Motors' wireless battery management system.

GM is touting the system as a first in any EV and was created with Analog Devices. It will be standard on a full range of GM EVs, with the company aiming for at least one million global sales by mid-decade.

Those vehicles will be powered by GM's proprietary Ultium batteries, produced at a new US $2.3 billion plant in Ohio, in partnership with South Korea's LG Chem.

Unlike today's battery modules, which link up to an on-board management system through a tangle of orange wiring, GM's system features RF antennas integrated on circuit boards. The antennas allow the transfer of data via a 2.4-gigahertz wireless protocol.
