The PW9253A PathWave Advanced Battery Test and Emulation software from Keysight Technologies is a powerful application for performing realistic battery testing, creating accurate battery models and emulating battery conditions using advanced two-quadrant power supplies.
Main features:
- Test and emulate batteries up to 200 kW and 2000 V
- Four operating modes: Emulation, Profiler, Discharge/Charge, Cycler
- Create custom battery models including SoC, Voc, Ri
- Create custom battery models. SoC, Voc, Ri
- Import of external battery models (CSV with Voc, SoC, Ri)
- Emulation of different battery states at different temperatures
- Simultaneous measurement of voltage, current, capacity and temperature
- Lifetime cycle tests with up to 1000 charge/discharge cycles
- Protection functions such as temperature monitoring and charge cut-off (e.g. for NDV for NiMH and NiCad batteries). with NDV for NiMH/NiCd)
Advantages:
- Reduction of test duration through battery-free emulation of real operating states
- Safe test environment for device and battery development
- Detailed analysis of ageing effects and design changes
- Seamless integration through API functionality
Profiler: Creation of individual battery models
The profiler function enables the creation of precise battery models using real charging or discharging processes. The model contains up to 200 points with information on open circuit voltage (Voc), series resistance (Ri) and state of charge (SoC).
Emulation: Real conditions without a real battery
By loading a battery model, PW9253A emulates the behavior of a real battery in real time. This allows safe, repeatable and controlled test scenarios - including dynamic load profiles.
Cycler: Life and reliability tests
Perform up to 1000 charge/discharge cycles and monitor capacity loss, voltage, current and time. Cutoff conditions automatically terminate the cycle at defined thresholds.
Supported devices:
Supports a wide range of Keysight two-quadrant power supplies, including:
N6705A/B/C, N678xA series, N79xxA series, RP79xxA series, E36731A, DAQ970A/973A, 34970A/34972A
