E36731A Battery Emulator and Profiler

Quickly Visualize, Emulate, Profile and Cycle Batteries

The Keysight BV9210B Pathwave BenchVue Advanced Battery Test and Emulation application software provides a test environment for you to easily run battery tests, generate battery models and perform battery emulation using one or more Keysight two-quadrant power supplies. The emulation function allows you to quickly output the desired battery operation conditions. It allows you to cover various test scenarios without having to wait for a real battery to go through discharging or charging conditions. Integrating the BV9210B software with Keysight’s advanced two-quadrant product families, covers a broad range of low to high power level applications, across various industries from consumer electronics, medical devices, e-mobility, residential energy storage and automotive. The BV9210B also supports RP7900 Series operation in primary/secondary mode which enables parallel units to be configured easily for greater output current/power.

Profiler - Creating Battery Model Tailored Around Device Behavior

A battery profiler is a must tool to have if you are working with different batteries and need to create your own custom battery model library. This ensures you are getting the most accurate models for battery life predictions tailored to your devices and working scenarios. The BV9210B software has the capability of creating custom battery models. It creates a battery model when discharging or charging a physical battery. Discharging a battery can be performed by either static current or dynamic current loading profile or constant resistance or constant power. A battery model created by the BV9210B will consist of a file with of up to 200 points, each point includes the open circuit voltage (Voc), series resistance (Ri), and state of charge (SoC). The software will continue to build up battery model automatically until the stopping condition is reached. While discharging or charging a battery, in real-time the software continuously captures parameters like Voc, Vt, Ri, Current, Time, Capacity, SoC and Temperature. The profiler also can export all graphed data while the test is running for further analysis.
