Battery Rapid-Test Methods

Contributed Commentary by Isidor Buchmann, CEO & Founder, Cadex Electronics, Inc.

A battery resembles a living organism that cannot be measured; only estimated by diagnostics similar to a doctor examining a patient. The accuracy of rapid-testing varies according to symptoms that change with state-of-charge (SoC), agitation after charge and discharge, temperature and storage. A rapid-test must distinguish between a good battery that is partially charged and a weak pack that is fully charged. Both will deliver similar runtimes in the hands of the user but have different performance levels. Read more about Battery Rapid-Test Methods

The Role of Power Electronics and Energy Harvesting in the Future of Batteries

Contributed Commentary by Brian Zahnstecher, Sr. Member of the IEEE, and the Principal of PowerRox

In just about any application in the world of electronics, energy storage plays an important factor.  Whether it be a battery that limits charge time or life of portable electronics, a Telecom’s capacity to sustain hold-up in a catastrophic situation, a data center’s ability to reduce the power bill, or a sensor’s ability to capture, analyze and transmit key telemetry data from a very harsh, potentially inaccessible environment.  In just about any market or vertical we have encountered at PowerRox or in previous, professional lives, there is a maniacal focus on increasing the density of energy storage solutions (as well as power electronics density) in electronic gizmos.  Thanks to some very high-profile incidents with lithium-ion batteries, safety is a receiving an ever more scrutinizing eye, but this can still come somewhat at odds with the desire to push energy densities.

Batteries by Design: Unique Perspectives Through Multi-Scale Imaging

Commentary contributed by Jeff Gelb, Carl Zeiss Microscopy

Batteries are complex systems. From the protective mechanisms in the packaging to the finest details of the active materials, a wide range of structures must work together in order for a battery to function properly. As consumers and government agencies alike demand higher energy densities at lower costs per kwh, optimizing these complex systems is of critical importance to furthering battery technologies. In parallel with optimizing the functionality of the cells, it is equally important to ensure the safe and reliable operation of the battery product, during normal use, storage, or extreme conditions. Addressing these issues requires a full understanding of a battery’s life cycle, from formation through performance, so that root-causes can be identified and modifications to structure and/or chemistry may be made.

Battery Failures in the News: How Does a Manufacturer Mitigate Risk?

Contributed commentary by Jim Green, Global Business Manager, Energy Storage, CSA Group

Recent safety recalls of portable device and computer batteries point out the challenges that manufacturers face in an environment where consumers continually demand smaller devices, with higher power, longer run time, and lower cost. Manufacturers strive to make these improvements without sacrificing safety, quality and manufacturability. Read more about Battery Failures in the News: How Does a Manufacturer Mitigate Risk?

Getting Battery Energy Storage Systems Installed in the Built Environment

Contributed commentary by Laurie Florence, Principal Engineer, UL

Battery energy storage systems are being utilized for numerous applications including support for intermittent renewable energy sources, grid balancing and load leveling, reliability and resiliency, and providing costs savings to users by providing power during peak/high cost times. Utilities have been installing energy storage at various utility controlled areas to provide renewable support or ancillary services. More recently, these systems are being installed at commercial sites, on private property and even within mixed occupied buildings including residential locations.  Read more about Getting Battery Energy Storage Systems Installed in the Built Environment

Ultra-Fast Charging: Respecting the Limits of a Battery when Feeding

Content Contributed by Isidor Buchmann, CEO & Founder, Cadex Electronics, Inc.

Consumers demand faster charging times. Leading in this movement is the electric vehicle (EV) industry that strives for charge times similar to filling up a vehicle at a gas station. Pumping 50 liters (13 gallons) of fuel into a tank holds a calorific value of 600 kWh. The fill-up is quick. An EV battery, in comparison, only stores between 50 to 100 kWh of energy and charging takes a long time. Read more about Ultra-Fast Charging: Respecting the Limits of a Battery when Feeding

Gone in 60 Seconds: Five Ways Next-Generation Ultrafast-Charging EV Batteries are About to Change Everything

Contributed commentary by Robert A. Rango, President and CEO, Enevate Corp.

Electric vehicles are the most revolutionary development in the auto industry since the internal combustion engine. Every day they get more advanced and more popular. Electric cars and plug-in hybrids are projected to account for an average of 8 percent of all cars sold in the United States by 2020. While that shows tremendous growth in electric vehicles (EVs), you dont have to be a statistician to notice that this is still a fairly small percentage. EVs are becoming more affordable (although they may not be as affordable as cars with internal combustion engines until the 2020s). Plus, there are great government incentives that make it easy, and at least comparable in price to standard auto sales, for people to switch to EVs. So whats holding the market back?
