A battery electric vehicle racing in extreme environments
Glen Pascoe Principal engineer Williams Advanced Engineering UK
Williams Advanced Engineering joined the Extreme E fold in May 2019, as designer and supplier of the battery tech that will power the championship when it sets off on its maiden voyage in early 2021. The company has a wealth of experience and expertise, having built the batteries throughout the first four seasons of the Formula E Championship. New cells are designed to cope with all the rigors of Extreme E’s five formidable environments – from the Arctic to the Sahara Desert.
Racing to the future – designing EV race cars
Angus Lyon Director Rockfort Engineering Ltd UK
With over 20 years' experience in electric vehicle design and 10 years in electric race car design, Angus Lyon will provide an insight into the EV drivetrain systems employed in Formula E, Formula 1 and electric prototype race cars. His talk will cover the technologies and powertrain architectures used, as well as the considerations and requirements that must be met when delivering motorsport EV powertrain, control and battery systems.
11:30 - 12:00
Increasing the power density of an e-motor
Arnaud Martin Chief engineer - motorsport Integral Powertrain Ltd UK
The presentation will discuss the basic considerations needed to enable gains in electric motor power density. We will look at technical aspects of an electrical motor, its design, architecture and manufacture. All this to maximize performance and efficiency in motorsport.
Electric single-seater design and build
Terence Goad Director Performance Projects UK
This presentation will discuss how an electric single-seater car was designed, built and delivered within two months.
13:00 - 14:00
Advances in battery technology
Paul Freeland Principal engineer Cosworth UK
Synopsis to follow.
From click to performance – damper dynamics and static damper graphs
Jonas Jarlmark Näfver Manager vehicle dynamics Öhlins Racing AB SWEDEN
A large number of engineers with race teams and manufacturers use the static damper graph as their sole information when adjusting dampers. In a steady-state situation, this is a reasonable approach. The only problem is that the life of a damper is highly dynamic, and the actual response can be far off from the static graph used for making decisions. This workshop will discuss the physics of how the static and dynamic response of the damper can affect the performance of the vehicle. The discussion will introduce the balancing required between opposing needs and competing traits when trying to improve the overall performance of the vehicle for a specific track, driver and session.
15:00 - 15:30
From valve to wheel – racing engine and vehicle development
Julien Feddra Commercial director Rotronics FRANCE
In a world where 1/100 of a second is the difference between the winner and the looser, any improvement in the racing car or bike will increase your competitivity. Rotronics was born to solve 500cc two-stroke bike development, engine dyno and chassis dyno problems. Based on the company's 30 years' experience, it offers a wide range of tools to help clients boost their performance. From valve to wheel, Rotronics offers valvetrain, flow bench, engine and vehicle testbeds. Products include a standard roller dyno 4WD synchronized up to 400km/h, and a smart hub-dyno concept where users can run 4WD synchronized or control each wheel speed independently. Therefore, the transmission strategy is also balanced. Speed offset could be applied between front/rear/left/right.
An aerodynamic master class
Willem Toet Aerodynamics specialist/senior manager aerodynamic services Sauber Aerodynamics AG SWITZERLAND
With fun examples, Willem will explain the main concepts behind aerodynamics. He will try to give you a mental picture of what happens with the molecules of the air as they move around objects to “feel” what the Bernoulli equations calculate. He will explain how motorsport diffusers work and how creating vorticity (flow rotation) is used in to bring higher energy air into contact with surfaces that otherwise would have low performance. Then he’ll touch on how to create working cooling ducts and multi element wings. This talk assumes a good engineering brain but no specific prior knowledge of aerodynamics.
