Controllers, PIDs, PLCs & Microcontrollers

Controllers — PIDs, PLCs, and microcontrollers — are the embedded brains that run battery production equipment and the cells they produce, from formation chargers to pack-level Battery Management Systems. As a hard skill it requires fluency in PID loop tuning, PLC ladder logic for line control, and bare-metal or RTOS programming for microcontrollers driving pack hardware. Practitioners apply this across the stack: tuning a PID on a calender roll's gap servo, writing PLC code for a cell-stacking station, and coding BMS firmware that monitors hundreds of cells while protecting against thermal runaway.
