The battery and energy systems of Formula E cars will change significantly with the introduction of the third generation (Gen3) design in 2022. The Gen3 specifications are scheduled to last three seasons until 2025. In Gen3 cars, the battery will be lighter (so will the entire car), it will be capable of handling fast charging […]
FAQ
Formula E teams and technology partners
Formula E has a total of 12 teams with 24 drivers and 24 cars. In addition, there are numerous technology sponsors. This third and final FAQ in EEWorld’s Formula E series reviews some of the current technology partnerships of the various teams. Powertrain partners are particularly important, and battery cooling is becoming an issue, especially […]
Formula E Gen2 and attack mode
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 […]
Optical tweezers move nano-objects, Part 2: The optical path
A combination of optics, lasers, electronics, and combined with advanced physics principles, allows “touch-free” physical manipulation of molecules, viruses, and other nano-sized objects. Part 1 of this article presented the goals of the optical-tweezer design and some of the reasoning which leads to it. This part continues to build up to a larger, complete system. […]
Optical tweezers move nano-objects, Part 1: The Principles
A combination of optics, lasers, electronics, and combined with advanced physics principles, allows “touch-free” physical manipulation of molecules, viruses, and other nano-sized objects. How do you manipulate and move tiny objects such as pieces of DNA or living cells? Conventional mechanical or vacuum tweezers, no matter how small, couldn’t grab them and would cause damage […]
Advances in memory system architectures – Virtual Roundtable (part 2 of 2)
The second part of our Virtual Roundtable series on memories focuses on “advances in memory system architectures.” We are joined by Nando Basile (NB), Technology Marketing Manager for Memory with X-FAB, Bob Brennan (BB), Vice President of Emerging Memory at Micron. JS: What design challenges should system architects be aware of when employing persistent memory? […]
Emerging memory technologies – Virtual Roundtable (part 1 of 2)
Hosted by Jeff Shepard In this Virtual Roundtable session on emerging memory technologies, we are joined by Nando Basile (NB), Technology Marketing Manager for Memory with X-FAB; Bob Brennan (BB), Vice President of Emerging Memory at Micron; and Mark Reiten (MR), Vice President, Licensing Business Unit, Silicon Storage Technology (SST), a wholly-owned subsidiary of Microchip […]
What are inertial sensors?
Inertial sensors are used to transduce inertial force into measurable electrical signals to measure acceleration, inclination, and vibration of an object. Micromachining technology has made it possible to produce MEMS (Micro Electromechanical System) inertial sensors using single-crystal silicon sensor elements. These micron-sized sensors meet all major system design drivers like low-cost, high performance, high precision, […]
Kelvin 4-Wire sensing solves the “IR Drop” problem
Novice engineers usually don’t learn about this problem and its solution in school, but “practicing” ones learn about it soon enough! Problem: I need to determine the change in resistance of a low-resistance sensor located many meters away. My plan was simply to apply a known voltage across the thin-wire sensor leads and measure the […]
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. […]
