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 similar to Bluetooth but with lower power. Slave modules report back to an onboard master, sending measurements of cell voltages and other data. That onboard master can also talk through the cloud to GM.
- p1necone 6y agoThey're trying really hard to make this sound like an improvement, but it's really not. Wiring is not going to be visible in the car - and it's going to be much more foolproof. What if someone turns on an RF jammer in the car next to you on the highway? Surely you still need wires for critical systems even if you run some stuff wirelessly.
