Triumph TE-1 Electric Prototype Ready For Road Testing!


Today marks the official end of the collaboration stage of the TE-1 project, with the completion of the prototype demonstrator, which is now fully ready for the next Triumph-led stage of the project to begin – the live testing programme.

The unique collaboration between Triumph Motorcycles, Williams Advanced Engineering, Integral Powertrain Ltd, and WMG at the University of Warwick funded by the Office for Zero Emission Vehicles through Innovate UK, was set up to create ground-breaking developments in specialist electric motorcycle engineering and innovative integrated technology design.

Phase 3 of the TE-1 project has now reached its completion, with the final build of the prototype demonstrator. Integrating for the first time all of the latest and final innovations from the project partner workstreams, the prototype demonstrator features:

– Triumph: final chassis, including frame, rear sub-frame, cockpit, panels and wheels, final drive system including transmission and Gates Carbon belt drive, electronics, Öhlins USD cartridge forks, unique prototype Öhlins RSU, Brembo M50 monobloc calipers, and Triumph motorcycle control software

– Williams Advanced Engineering: final iteration of prototype WAE battery pack incorporating dedicated cell packaging for optimum centre of gravity, vehicle control unit, DCDC converter, integrated cooling, charge port, and styled carbon covers

– Integral Powertrain: final prototype powertrain with scalable integrated inverter and combined motor with silicon carbide switching technology and integrated cooling

– WMG, University of Warwick: final pre-live trial simulation completed, with all results indicating that the project is on course to deliver the intended performance and durability outcomes

Key project achievements during this phase include test results that exceed current benchmarks and targets set by the UK Automotive Council for 2025, providing a platform with great potential for future development in electric motorcycle performance.

The overall objective of the TE-1 project has been focused on developing electric motorcycle capability, in order to provide an input into Triumph’s future electric motorcycle offering, driving innovation, capability, and new intellectual property, and enhancing the credibility and profile of British industry and design.

With the completion of the prototype demonstrator, the full live testing phase of the TE-1 project can now begin (phase 4). Over the next 6 months the prototype demonstrator will undertake an extensive live testing programme within Triumph’s state-of-the-art facilities, which will encompass:

Rolling road testing – core functional assessment to include:

Throttle calibration
Powertrain performance mapping
Power and torque output
Range and battery consumption assessment
Rider mode development
Software functionality validation
Thermal optimisation

Track testing – encompassing dynamic rider assessment to include:

Braking and braking regeneration strategy
Traction control
Front wheel lift control
The testing programme has been designed to provide direction into the final set up and calibration of the prototype demonstrator.

At the completion of the live testing phase, estimated to be Summer 2022, the prototype demonstrator will be updated with its final body panels and paint scheme, in preparation for active track demonstration, and media engagement. At this time, the full results of the project including the final specifications and testing outcomes will be published, as well as insights and key facts on how the TE-1 delivers on the project targets for innovation and sets new standards for the motorcycle sector overall, including final battery and range performance. This will be supported by an opportunity for the media to talk to the team, see the prototype in action on track and hear from the development test riders.

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 optimise 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 has also been 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 has 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.

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.
