We showcase the Keysight’s E36731A Battery Emulator and Profiler and its astounding features allowing it to test all kinds of batteries. This instrument is equipped with both a power supply and an electronic load allowing it to both charge and discharge devices and batteries and use it to automatically create battery profiles at various test conditions, which you can then use to emulate the different states of charge (SoC) of your device under test (DUT). Additionally, the easy-to-use battery cycler lets you monitor battery aging and stability. The E36731A plus the BV9211B software is a complete battery emulation solution, allowing you to test, emulate, and automate in a compact bench form factor.
