Software tool takes the guesswork out of battery life predictions
Energy Micro has introduced a software tool enabling designers to accurately predict battery cell life expectancy in applications based on its low power EFM32 Gecko microcontrollers. Called the energyAware Battery Estimator, this free tool provides a full simulation of total system energy usage, that takes into account actual battery source, MCU energy modes, peripherals employed and external circuit components.
In simulation mode, system battery voltage output is displayed against time (years) in graph format, with the battery capacity rating (mAh), average MCU current consumption (µA) and estimated system operating time (years) shown numerically alongside. The set-up of a complete system simulation, its energy modes, their related operating times and associated peripheral functions and external component current consumption is via an intuitive GUI, comprising simple drop-down menus, slider bars and checkboxes.
