Formula E Gen3 smaller batteries, regen and fast charging
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 […]
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 […]
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 […]
