Simulator Emulates Battery Performance End To End

Forecasting shorter design and test cycles for mobile devices, Tektronix claims that the Keithley 2281S battery simulator/precision dc power supply is the industry’s first to emulate battery performance from full charge to total discharge. It does so using a battery model that includes state of charge, amp-hour capacity, equivalent series resistance, and open circuit voltage.

Battery models simulated or played back by the 2281S can be obtained in a number of ways. One is to use the instrument’s battery test function to perform a full test on a battery intended for a particular design. After the test, a battery model can be generated based on the measurement results of the battery charging process. Battery models can be edited, created, imported, or exported in a convenient CSV file format. Alternatively, a battery model can be created according to a battery’s chemistry and the manufacturer’s specifications.

The 2281S incorporates a bright, 4.3-inch TFT display that shows voltage, current, amp-hour readings, source settings, and many additional settings in large, easy-to read characters. Functioning as a power supply, it delivers a maximum output of 20V and 6A. Measurement accuracies are 0.02% for voltage and 0.05% for current and resolution of current measurements is as low as 10 nA
Price for the Keithley 2281S starts at $2,990. For more info and specs, visit
