On: Reverse engineering my e-scooter and rewriting the firmware in Rust

[hn_submit]

I can imagine a future where batteries and chargers communicate using an open-source protocol just as they are doing now over USB.

If the batteries are a full pack which contain their own internal charge controller, etc. Raw cells can't communicate anything.

The problem is the consumer can't tell the difference between a well engineered pack and one that will explode in their apartment overnight.
