People seem worried about the connection being wireless on this battery. As far as I can tell from the article, the only consequence of a connectivity loss is: GM gets less data. It doesn't seem consequential to the consumer.

The vehicle's central BMS has a cloud connection but that's a separate issue. > 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.

Forget about connectivity loss, the worst case here is the ability for an attacker to remotely turn your battery into a bomb. End-to-end encryption does not come close to covering all possible attack vectors.
