Description
Firmware teams often test battery-powered products on a plain bench supply that behaves nothing like a cell. The Keysight E36731ABV battery emulator bundle targets that gap with emulation and profiling. Lost in HCM lists it for rental and sale in Vietnam.
What a battery emulator changes
A normal supply holds one voltage. In contrast, a battery emulator lets the voltage move the way a cell does as charge drains, so your product sees realistic sag under load. Profiling works the other way. First, it records how a real battery behaves. Then you can replay that behavior on the bench. The source listing names both functions for this bundle.
What the base unit offers
Keysight’s E36731A page lists one output with up to 30 V, 20 A and 200 W. It also describes source and sink operation. So, a sink lets the unit absorb current, which helps when you test chargers. However, the ABV code points to a bundle, so ask Lost in HCM to itemize the unit, software and licenses in the quote.
What the product photo shows
The photo pairs a bench unit with a monitor running BenchVue battery software. The screen shows a battery at 50 percent charge, state-of-charge curves and a voltage and current trace. It also shows pack settings such as series and parallel counts. As a result, you can see the workflow is PC-driven rather than knob-driven.
Teams that put the Keysight E36731ABV battery emulator to work
- Firmware groups that check low-battery warnings and safe shutdown.
- Charger and power-management developers who need repeatable battery behavior.
- Product teams that compare pack layouts before they buy cells.
- Wearable and IoT groups that study power budgets across a full discharge.
Rent for a program, buy for a lab
Rent the Keysight E36731ABV battery emulator for a firmware release or a charger program, but buy it when several projects share the bench all year. Then request a quote from Lost in HCM with your voltage and current needs, the profiles you plan to run and your delivery site. Related gear sits under power supply listings. Keysight’s Keysight E36731A page has the base-unit details, and you can contact SMK Vietnam for help.
E36731ABV questions
What does the E36731ABV bundle contain?
The source lists a battery emulation and profiling bundle. Ask Lost in HCM to itemize the unit, software and licenses.
Can it also test chargers?
Keysight describes the E36731A base unit as source and sink capable, so it can absorb current. Confirm the setup you need in the quote.
Does it replace real cells in final testing?
No. It gives repeatable behavior during development. Final qualification should still use real cells.
