6 FAQs about [Battery charging current instrument]

How do you charge a battery with an SMU instrument?

To charge a battery using an SMU instrument, set the voltage source to the battery's voltage rating and the current limit of the source to the desired charging current. At the start of the charging cycle, since the battery voltage is less than the SMU instrument’s voltage output, current will flow into the battery.

How to draw current from a battery?

To draw current from a battery using an SMU instrument, set the voltage source of the SMU instrument to a lower level than the battery voltage and the SMU’s current limit to the desired discharge rate. When the output is enabled, current from the battery will flow into the HI terminal of the SMU instrument.
