What had to be solved
The controller had to manage electrical and hydraulic parts of a laboratory flow-battery setup and transfer experiment data to a PC.
Projects / Measurements, sensors and data acquisition
Flow battery control board
Laboratory flow-battery controller: pumps, charging, DC/DC converter, output switching, current and voltage measurement, USB CDC data transfer.
What the project reached
A working controller basis was prepared: pump and power-node control, bidirectional current measurement, power-source recognition and USB telemetry.
Project materials
Photos and working materials
Engineering context
Important constraints
Electrical behavior is linked to electrolyte circulation.
The experiment required observable data over time.
The controller had to support external and autonomous power modes.
