Battery Emulator and Profiler enables improved their IoT designs

Keysight introduces a battery emulation and profiling system to help design IoT connected devices

The Keysight E36731A Battery Emulator and Profiler is a complete emulation system that identifies the impact of variables affecting the battery drain of internet of things (IoT) devices to enable development engineers to improve their device designs.

International Data Corporation (IDC) estimates that there will be 41.6 billion connected IoT devices in use by 2025, many of which will be portable, battery-operated devices requiring advanced battery management techniques. To ensure these devices perform well in the field, development engineers need to design for peak battery performance and validate those designs against real-life performance. However, testing the run time of a physical battery in a device is a challenging and time-consuming task that can slow time-to-market.

The Keysight E36731A Battery Emulator and Profiler addresses the battery testing needs of IoT device designers by giving them an integrated electronic load and power supply that can be used to emulate battery performance. By testing with an emulated battery, engineers can quickly assess the effect of design or software changes on battery life by instantly transitioning the battery’s charge state, allowing them to enhance their designs to achieve longer battery life and reduce device size.

The Battery Emulator and Profiler works with the PathWave BenchVue Advanced Battery Test and Emulation Software to provide a complete approach that generates battery profiles, increases battery profile accuracy, speeds testing with battery emulation, automates run-down and cycle testing, and offers Flexibility.

Carol Leh, Vice President and General Manager for Keysight’s Electronic Industrial Solutions Group’s Centre of Excellence, says, “rather than relying on intricate and time-consuming manual tests, the emulator allows engineers to quickly identify the current drain effect of critical factors such as hardware changes, software updates and temperature changes. This way, engineers can save time and improve their device designs by using an emulated battery for testing, without the need for physical batteries.”
