Current Limits Generator: Defining the Safe Operating Envelope

A battery’s safe operating envelope is not a fixed number. It’s a surface — varying continuously with temperature, state of charge, state of health, and operating history. Getting it wrong in the conservative direction costs performance and range. Getting it wrong in the aggressive direction costs cell life, and at the extreme, safety. The Current Limits Generator was built to define that surface correctly — from physics, not from conservative blanket rules. ...
