Battery profiling

[Giovanni Santoruvo]

Hello,

I have profiled a battery following the instruction of this link nPM1300 EK - Get started - nordicsemi.com .

Since I cannot use the battery NTC, I have placed a jumper between the NTC pin and the 10kOhm one on the nPM1300EK.

After the profiling, I have checked the current and voltage measurements and I have noticed that during the discharge the current is not constant, but pulsed (as shown in the picture).

I would like to know if this is normal or not.

I thank you in advance for your reply.

Best regards,

Giovanni

Hi,

The discharge curve is normal. During battery profiling the battery is discharged for short period, then the battery voltage is measured. The pulsing is to allow the battery voltage to recover after discharging before measuring the voltage to get accurate results for battery profiling.
