Sourcing and measuring battery cycles from one box

It is practical to characterise charge/discharge cycles of rechargeable batteries using an SMU (single-source measurement unit), writes Mary Anne Tupta from Keithley Instruments.

Rechargeable batteries are commonly characterised using charge/discharge cycling, which provides useful information on internal chemistry, capacity, usable cycles, and lifetime.

In production, this technique…
