Formula E is an all-electric-powered FIA (Fédération Internationale de l’Automobile) championship that began in 2014. In 2018, ABB is brought its name to the series, which is now known as the “ABB FIA Formula E Championship.” The races are set to 45 minutes plus one lap. During the first four seasons, drivers made one mandatory […]
FAQ
Flow batteries – What’s ahead?
Flow batteries have emerged as a commercial alternative that makes economic sense for certain application profiles. Additional development is still needed for flow batteries to be a mainstream energy storage technology. There are probably hundreds of research efforts worldwide. The following is a sampling of key areas of focus for flow battery research and development. […]
Flow batteries – What can you use them for?
Flow batteries are suited for use in several application areas, including utility-scale energy storage, microgrids, renewables integration, backup power, and remote and off-grid power. Flow batteries are highly scalable, and their power and energy ratings can also be scaled independently. They have very little or no self-discharge current. Flow batteries have demonstrated cycle lives of […]
How do flow batteries work?
The heart of a flow battery is a specially designed regenerative fuel cell module. A conventional regenerative fuel cell operates on the basis of a reversible electrolysis electrochemical process and can be either an open system (where water can be added, and hydrogen and oxygen removed) or a closed system. These electrolysis-based regenerative fuel cells […]
Shedding light on how much UV-C you need for disinfection
The idea of using UV-C light to kill the COVID-19 virus by disrupting its RNA has captured the imagination of many in the technical community. Unfortunately, important application details about factors such as necessary exposure time and intensity levels may be hard to discern, particularly for those who are new to the technology. A complicating […]
How to improve system performance with fan controls and protections
When an end system produces excess heat, designers commonly turn to dc fans to provide forced-air cooling for improved heat dissipation. Based on the well-known thermal-convection principle, forced air cooling should typically go beyond simply selecting a fan and running it full-time in your application. This full-time operation suffers from both its inefficiency and long-term […]
Energy harvesting applications considerations – Virtual Roundtable (part 2 of 2)

Joining us for this virtual roundtable are: Dr. André Mansano (AM), CTO at Nowi; Graeme Clark (GC), Marketing Manager, Energy Harvesting Business Unit, at Renesas Electronics, Ken Imai (KI) Sr. Manager, Product […]
Design challenges when using energy harvesting – Virtual Roundtable (part 1 of 2)
The first part of EEWorld’s two-part “virtual roundtable” discussion on energy harvesting considers technical challenges and design tradeoffs for engineers using energy harvesting power sources. Joining us for this virtual roundtable are: Dr. André Mansano (AM), CTO at Nowi; Graeme Clark (GC), Marketing Manager, Energy Harvesting Business Unit, at Renesas Electronics, Ken Imai (KI) Sr. […]
Protecting autonomous vehicle control circuits
The subsystems that make up an autonomous vehicle should be bullet-proof when it comes to electrical interference and transients. James Colby, Prasad Tawade Littelfuse, Inc. Those who follow autonomous vehicle technology are usually well aware of its benefits. But the safety and convenience autonomous vehicles offer can only come if the vehicle electronics is reliable […]
New ferroelectric material could boost piezoelectric actuator technology
If you’ve used an ink-jet printer or a tiny hearing aid, chances are those devices have employed lead-zirconium-titanium oxide (PZT, Pb(Zr,Ti)O3) piezoelectric ceramics as a means of generating ink droplets and amplified audio. These and numerous other applications have long used actuators and sensors employing piezoelectric materials which deform in response to an applied electric […]
