Improve Tab to Terminal Connections in Battery Pack Manufacturing

Josh Johnson October 8, 2016

Geoff Shannon, Amada Miyachi America, Inc.

Battery packs have become an integral part of everyday life, powering a growing range of portable electronic devices, cordless power tools, energy storage, and hybrid and electric vehicles. Tab to terminal connection welding is one of the key battery pack manufacturing applications. Manufacturers need equipment, systems, and automated lines that meet quality and production requirements for these products. Both resistance and laser products are well suited to integration into production lines that may be either standalone or automated operation. To maintain the required throughput that offers high quality and yields, users must have a clear understanding of which process is best for the particular battery pack size, tab and terminal material, type, and thickness. In addition, the selected process and integration solution should include process monitoring, process data management, and weld quality assessment.

Adaptive Charging: Extending Battery Life and Reducing Costs in Mission Critical Telecommunications Standby Systems

The accelerating growth of Internet of Things (IoT) devices and applications require continuous investment in telecommunications networks to provide the connectivity for millions of new devices. As more devices connect to the Internet, service outages become more impactful to the people and businesses that rely on IoT applications. Safeguarding telecom networks from power outages is the Valve Regulated Lead Acid (VRLA) battery. Stationary VRLAs are ubiquitously used at broadband, wireless and cable sites, and millions are in service across the country. Unfortunately, almost all of these batteries, and thus the sites that depend on them, are vulnerable to a reliability-damaging standard: float charging. While float charging will maintain batteries at full charge, it can have a damaging impact on the service life of the battery, which introduces risk and increases maintenance costs. There is a better way to charge batteries, Adaptive Charging, that mitigates the degrading effects of float charge, extending battery life and reducing maintenance costs.

Rogers Corp., Power Electronics Solutions (PES)

Interest in electric vehicles (EVs) and hybrid electric vehicles (HEVs) is growing steadily as battery technologies improve and the driving range of such vehicles increases. Perhaps as important, EVs/HEVs offer a “green” alternative to traditional vehicles powered by internal-combustion gasoline engines.

The market for lithium batteries and battery packs is booming. With extensive applications in automotive, IT, aerospace, consumer electronics and a myriad of industrial sectors, the usage of rechargeable lithium batteries is growing throughout the world. The market for lithium-ion batteries alone is expected to exceed $30 billion in the next few years. Read more about Protecting Lithium Batteries and Battery Packs from Runaway Thermal Events …

How to Measure Battery Internal Resistance Using the Current Interrupt Method

Josh Johnson November 16, 2016

James Niemann, Analog Design Engineer, Tektronix

One of the demonstrations we often set up at battery conferences is to use a source measure unit (SMU) to measure the internal resistance of an energy storage device such as a battery or a fuel cell. In such demonstrations, the SMU changes the load current from the battery operating current or the polarizing current to the open circuit potential and simultaneously measures the change in cell voltage. In this “current interrupt method,” the battery’s internal resistance is equal to the change in voltage divided by the change in current.
