Design for Better Battery Life

The Keysight E36731A battery emulator and profiler is an integrated electronic load and power supply developed to use with Keysight PathWave BenchVue battery emulation software. An emulated battery gives you a known good reference for testing at any charge level. Quickly assess the effect of design or software changes on battery life by emulating any battery charge state. Leverage emulation and precise current drain analysis to achieve longer battery life or to reduce the size of your device.

  • Generate accurate battery profiles using the simulated current drain of a device.
  • Instantly emulate any battery charge state and display real-time current drain data.
  • Achieve accurate battery run-down tests by emulating your device’s current drain.
  • Estimate battery aging effects to predict device performance throughout its lifetime.
  • Streamline your workflow with an integrated power supply and an electronic load.
  • Creates a battery model for any battery type.
  • Power up to 200W, 30V, and 20A.

Validate and Extend Battery Life

Analyzing the current drain and conducting run-down battery tests of your designs pose several difficulties. The manual process of charging and discharging a battery is time-consuming, and it's crucial to test it at different charge levels as battery characteristics vary. Furthermore, battery parameters and charge levels must be identical when comparing test results. Achieving this is very challenging with physical batteries. Additionally, it is difficult to determine how long a device will last on a single charge, and often battery life claims do not match reality.

Keysight designed the E36731A battery emulator and profiler and BV9211B advanced battery test and emulation software to solve these challenges. This demo video guides you through the process of using the solution to verify and prolong the battery run time of your device.
