Need Voltage Current Data Logger Suggestions.

Hello, I apologize if this is not the correct forum to use for this.

I’m doing some work with older Prius traction batteries, these are 7.2v 6 cell NiMH modules. I have a separate charger / balancer that I use with each module.

What I want to build is a data logger that will record the voltage and current as the battery is discharged / charged.

My thought is that I would capture the readings at the terminals of the battery. Log that data to usb thumb drive.

Any suggestions on where to start?

I’m thinking I need a board to measure current and voltage like:

KR Sense Current and Voltage Sensor - 90A

In stock SEN-16408

But I’m not sure about what to use to log the data.

Any advice would be appreciated.

Thank you.

Hello, You can do this by adding an Arduino, a microSD card and a MicroSD card storage board to your project. Arduino will read data and store the data to the microsd card in a text file.

Thank you!
