What had to be solved
The setup needed a separate protective node that could shut down the power circuit independently from the main experiment controller.
Projects / Industrial automation and embedded control
Flow battery safety shutdown board
Independent safety shutdown board for a flow-battery stack: current and voltage measurement, emergency input, relay control and latched fault state.
What the project reached
A specialized shutdown device was prepared with measurement, external emergency input, relay output and manual reset.
Project materials
Photos and working materials
Engineering context
Important constraints
Safety logic had to be separate from experiment logic.
After a fault the stack must not restart automatically.
Simple diagnostics and manual reset were important for laboratory operation.
Work done
What was included
STM32-based shutdown-board circuitry.
Voltage and current measurement inputs.
External shutdown input and manual reset.
Relay output control.
Firmware with ADC calibration, physical-unit conversion and filtering.
