Battery Testing with KickStart Software and Keithley SMUs
Battery Testing Made Easy Tuesday, December 19, 2023
The best way to test any kind of rechargeable battery is to start with the upgraded KickStart Battery Simulator App from Tektronix / Keithley, which provides battery testing, battery emulation, battery simulation and battery modeling. With a growing number of battery-powered devices in our homes and factories, on our desks and roads, and in our pockets, it is imperative that the batteries we use …

Testing Battery Resistance Wednesday, December 13, 2023
It’s easy to think of a battery as a bucket full of energy. When we would like some energy, we connect our circuit and pour the energy out. However, this analogy doesn’t account for internal impedance. A better analogy is that batteries are like water bottles. When a water bottle is tipped over, the water cannot flow out freely because a nozzle restricts the flow. Similarly, a battery has internal …

Testing and Debugging PMICs with Ease Friday, September 22, 2023
Adaptive Power Optimization is Revolutionizing PMICs “There is no better way to save energy and cut bills than by turning all electronic devices off.” This basic piece of advice is the underlying principle and philosophy behind any form of energy management applied to energy consumption optimization, and in general in so-called adaptive power optimization. In the case of battery powered …

4 Key Testing Phases for Power Conversion Equipment Tuesday, February 14, 2023
While the types of electrical tests required during the design and production of power conversion equipment are similar to those required for previous generations of devices, the adoption of wide-bandgap materials like silicon carbide (SiC) or gallium nitride (GaN) requires added rigor and new test strategies. Bench testing continues to play an important role at every stage of the development of …

Are You Keeping Pace with Wide-Bandgap Test Requirements? Tuesday, September 13, 2022
A new generation of wide-bandgap (WBG) materials such as silicon carbide (SiC) and gallium nitride (GaN) are becoming more prevalent. Electrically, these substances are closer to insulators than silicon and other typical semiconductor materials. Their adoption is an effort to overcome limitations of silicon that stem from it being a narrow bandgap material, which leads to undesirable conductive …

Using Your Source Measure Unit as a Power Supply Friday, August 12, 2022
Keithley’s line of Touch Test Invent™ graphical Instruments have the ability to locally run custom scripts written in the Test Script Processor (TSP™) language. These scripts allow the instrument to execute code in real time written by you. The example script provided allows a 2400 Series Graphical SMU to function as a power supply by outputting a constant wattage. A traditional power supply …

Forming the Best Solution for Battery Formation and Aging Tuesday, July 12, 2022
Current markets are leading to high demand for battery cells. One way for manufacturers to increase throughput is to reduce the time spent making each battery. The formation and aging stage is the most time consuming part of the cell manufacturing process. Ensuring that the right equipment is used for the job can help with some of the challenges facing formation and aging. What is Formation and …

Energy Storage Devices: a Battery Testing overview Wednesday, July 28, 2021
Energy storage device testing is not the same as battery testing. There are, in fact, several devices that are able to convert chemical energy into electrical energy and store that energy, making it available when required. Capacitors are energy storage devices; they store electrical energy and deliver high specific power, being charged, and discharged in shorter time than batteries, yet with …

Curve Tracer vs. I-V Curve Tracer Software Tuesday, April 27, 2021

Tektronix introduced the industry’s first curve tracer in 1955 to display characteristic curves for vacuum tubes, followed over the years by models for testing transistors, diodes and other solid-state devices. Tektronix curve tracers such as the 576 (below) and 370A/370B went on to broad industry acceptance until production eventually stopped in the mid-eighties. Approximating a power supply and an oscilloscope packaged in the same box, curve tracers source voltage while plotting voltage vs. current.
