PW9253A PathWave Advanced Battery Test and Emulation

The PW9253A PathWave Advanced Battery Test and Emulation software simplifies battery testing, modeling, and emulation. It works seamlessly with one or more Keysight two-quadrant power supplies. The emulation function allows you to output battery operating conditions quickly. This eliminates waiting for real batteries to charge or discharge. The PW9253A integrates with Keysight’s two-quadrant products to handle various power levels. It supports applications across consumer electronics, medical devices, e-mobility, energy storage, and automotive. The software also supports the RP7900 Series in primary/secondary mode. This mode allows parallel configuration for increased output current and power.

Profiler – Creating Battery Model Tailored Around Device Behavior – KEYSIGHT PW9253A

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 PW9253A 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 PW9253A 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.

Emulation – Battery Emulation Reduces Test Time – KEYSIGHT PW9253A

Battery emulation is a critical process as it allows one to understand how the battery or the device would behave in a real-life scenario when connected to each other. Using a battery emulator instead of a real battery has many advantages. A battery emulator helps to create a safer test environment and allowing to validate the various operation modes of the device. To emulate battery characteristics, start by loading a battery model into PW9253A Advanced Battery Test and Emulation software. The software algorithm will follow the battery model in real-time and emulate the battery behavior. The software allows two methods for battery models – open profiles generated by the software or importing external battery models with Voc, SoC, and Ri parameters in a CSV file.

For simplicity, you will only need to enter four parameters to emulate a battery – capacity rating, current limit, initial SoC, and a cut-off condition. While emulating a battery, it can simultaneously measure voltage and current continuously and save the measurement results. The software also has capability that allows you to load multiple battery models that have been created at different temperatures.

Cycler – Life Cycling Battery Characteristics 

The cycling function as the flexibility allows you to create a custom sequence of charging, resting, and discharging a battery at various test conditions. The software enables you to make up to 1000 cycle operations on the battery to determine the battery’s age effect and reliability under sequence test conditions. While continuously monitoring the battery’s health and recording test data parameters of capacity, terminal voltage, current, and time. The cut-off condition features allow you to define a stop condition where cycling will automatically stop once capacity loss percentage is reached.
