Want to build an auto charging and discharging system with DAQ

Hi. I'm a freshman here. Now I have the DAQ-6009 and a labview software and some electronic elements. I wish to build a lithium ion battery cycles testing system (mainly for auto-switching) in order to observe the changes in the electrode. How can I build this charging and discharging system? The details of the battery are attached. Thank you!!

Hi freshman,

 

your spec sheet already mentions some resistors for loading and discharging your Li cell.

 

- With your USB6009 you can drive some transistors to switch between charging and discharging. You also have some AIs (analog inputs) to measure Li cell voltage as well as currents (when using some reasonable shunt resistors).

- Make an electronics sketch, read the manual of your USB6009 for it's specs and then grab your breadboard to build your electronics.

- Look at the examples coming with LabVIEW on how to switch DO signals and how to measure voltages (read the manual on that topics too!)

Best regards,
GerdW

But how to control the transistors with DAQ?

software control your analog/digital outputs..
