PROJECT TE-1 – PHASE 3 OUTCOMES
Demonstrator Prototype

 

 

The Triumph TE-1 team began phase 3 by successfully building an initial mule bike which incorporated the battery, inverter, motor, and chassis into one machine for the first time. Using this platform, all of the project partners worked collaboratively to optimize software integration across the complex systems, involving hundreds of hours of detailed testing to ensure the functionality of all the features and software aspects behave accurately and intuitively, as a customer would expect. This was validated in real life simulation work carried out at WMG, involving detailed powertrain rig testing and simulations to assess safety critical items relating to motor function and vehicle control. Durability testing on the primary transmission was also conducted to ensure a full understanding of the fundamental differences in electric motor load application for vehicle use cases, efficiency, and consequences to gear life. Alongside this work, the Triumph-led design of the bespoke chassis focused on delivering the phase 2 styling intent as closely as possible. Phase 3 of the project is now complete with the fully assembled TE-1 demonstrator prototype, the photographs of which are revealed for the first time today. 

Steve Sargent, Triumph’s Chief Product Officer said “During phase 3 we have focused on building the physical foundation of Triumph’s first electric prototype motorcycle. I am pleased with the outcome of Triumph and the TE-1 partners’ efforts in creating a demonstrator bike that is not only visually so desirable with clear Triumph DNA, but also packaged with an exhilarating and thrilling brand-new electric powertrain that has such potential for the future. I look forward to continuing the development of this demonstrator vehicle through phase 4 and using our knowledge and capabilities to bring all of the partners’ cutting-edge technology together into a final result which will guide Triumph’s electric strategy for the future. Our experience tells us that at this stage of a project there is no substitute to genuinely riding a bike when developing driveability, handling and character, and we have ambitious targets focused on delivering a riding experience that is new and exciting, but ultimately intuitive and familiar. I am really looking forward to my first opportunity to ride the completed prototype.”

 

Following completion of Phase 2 of the programme in March 2021, which delivered a fully bench tested battery, Williams Advanced Engineering have now concluded work on Phase 3 which contained some critical gateways for the project.

In addition to supporting a number of hardware and software solutions; specifically integrating Triumph’s motorcycle control software to work in harmony with WAE’s controller and battery management system, the team have enhanced the integration of the mechanical and electrical solutions; optimising battery layout to balance mass and positioning within the chassis.

The demonstrator bike is now undergoing final battery level validation and calibration to ensure the performance results meet best-in-class power and energy density targets and for the rider, ensuring there is no compromise in performance at low levels of charge.

“Following an extended period of testing, we are thrilled to finally see the results of our work on a physical bike. By working with the team at Triumph, we have continued to push the boundaries of battery technology, keeping the rider in mind at all times” said Dyrr Ardash, Head of Strategic Partnerships, Williams Advanced Engineering “Because we have designed the battery from the ground-up, design has not been compromised and we have been able to push the boundaries of current technology, offering both performance and all important, range”.

 

“We are absolutely delighted to complete our part in this project and deliver what we set out to achieve which is a scalable, ultra-highly integrated motor and inverter, with no phase cables, busbars, or separate cooling circuits. For the TE-1 application, the motor achieves peak and continuous power densities of 13 kW/kg and 9 kW/kg respectively which is 60% higher than new APC technology roadmap targets for 2025. All of this has been achieved using materials and processes compatible with volume automotive production and importantly using a length scalable motor platform.

“The inverter concept, which is also scalable by tuning the number of Silicon-Carbide power stages for different diameter motors, has really delivered on performance. The TE-1 unit is capable of >500kW! This gives us the opportunity to optimise this platform for production.

“The integrated motor and inverter unit is now on the bike and is delivering on the target performance and cycle efficiency we engineered, modelled and simulated to achieve. We’re very much looking forward the feedback from bike-level testing and the benefits of our high efficiency on range.

“We’re really proud to have been a key part of this exciting project which has been a landmark for electric motorcycles and British industry.” Andrew Cross, Chief Technical Officer at Integral Powertrain Ltd.

“WMG have been working closely with Triumph to support the development of the motorcycle control unit via a comprehensive real-time evaluation process using two bespoke physical rigs. A 3D physical motorcycle model has been created and integrated with the first rig to allow the evaluation and refinement of the control unit under real-world driving scenarios, ensuring it behaves well before the integration into the initial prototype bike. The second rig has been utilised to support Triumph in evaluating the power and energy performance of the whole drivetrain as well as confirming its durability. We have also focused on control research and development at other levels, including advanced traction control and optimal brake blending strategies. The findings in energy system modelling, simulation and control, especially real-world case studies with electric motorcycles, gained through this TE-1 project have been utilised to develop teaching materials on energy systems, hybridisation and electrification technologies across education programmes at WMG.” Truong Quang Dinh, Associate Professor of Energy System Management and Control at WMG, University of Warwick.

“WMG have also been helping Triumph understand the opportunities and wider implications of electrification towards their business. This has included investigating the opportunities for electric two-wheeler charging networks, the need for domestic electric motorcycle recycling, the necessity to develop local battery supply chains and the direction that Triumph will need to take to ensure that they can design, develop, manufacture and distribute electric two-wheeled vehicles in the future. The findings from these studies are also providing direction to national and local governments, specifically around areas where policy intervention can support electric motorcycle adoption. 

“In many studies undertaken by WMG, bespoke computer-based models developed at the university (such as the university’s own UniWarp software), have been instrumental in understanding the best possible direction or action required for different scenarios. This approach has enabled WMG to quantify the environmental impact of electric motorcycles and has defined methods by which this can be further improved through new vehicle features, vehicle system sizing or new external collaborations.” Jim Hooper, Principal Engineer of Electric Vehicle Projects at WMG, University of Warwick.
