Williams develops electric powertrain for Triumph


Williams Advanced Engineering has developed an all-new battery powertrain for Triumph Motorcycles’ TE-1 prototype electric motorcycle.

The battery for the TE-1 has peak power of 170kW and continuous power of 90kW, with a capacity of 15kWh. This enables the motorbike to deliver 130kW of peak power and 80kW of continuous power.

Its 360-volt system also enables a fast-charging time of under 20 minutes (0-80%)

The motorcycle project – which also involves Advanced Engineering, Integral Powertrain, and WMG at the University of Warwick – has now reached the successful completion of phase two of its four-phase programme.

WAE has optimised the battery module layout to balance mass and positioning within the prototype chassis taking into consideration centre of gravity, space and relationship with the powertrain and charging approach.

A new and bespoke vehicle control unit has been integrated into the battery pack to minimise weight and packaging.

Funding has been provided by the Office for Zero Emission Vehicles via Innovate UK.

Dyrr Ardash, senior commercial manager at Williams Advanced Engineering, said, “Through this innovative project, we are delivering next-generation battery technology.

“The energy density of this new battery will be a significant step forward giving the rider more power, for longer.

“And whereas existing technology limits performance at low levels of charge, our lightweight, compact solution gives the rider all of the performance all of the time – regardless of battery charge. It also delivers class leading range.”

Nick Bloor, Triumph CEO, said, “This important project will provide one of the foundations for our future electric motorcycle strategy, which is ultimately focused on delivering what riders want from their Triumph; the perfect balance of performance, handling and real world usability, with genuine Triumph character.”
