Hi DCC Experts
Problem: There is a current fluctuation when using TI ADS131E08 to measure 4ch voltage and current. You can see the phenomenon as below.
This machine is a Battery Test system to charge and discharge the power battery. It need to precisely control the current and voltage. After this process, power batteries will be assemble to modules and pack and put in electric car.
The red line is the current signal. From the value of -3000(3A) to -500(500mA), You can see the current fluctuation.
Could you please check the schematic of the ADC part as below:
