Electric motor specialist e-Traction sought the consultancy in October 2011 to design a new bus based on its technology, according to Design Triangle director Andrew Crawshaw.
The concept had to facilitate the company’s ‘electric wheel motors, supported by batteries and a range extender module – a motor to charge the batteries, in case they run low,’ says Crawshaw.
Batteries will be stored in the roof of the bus, while recharging will be provided by an overhead pantograph, (hinged electrical rod), also in the roof.
The body of the 12m bus will be manufactured in two main parts using ‘aerospace composites’ and a triangulated pillar structure will help support the load-bearing roof and body sides.
Concepts for the interior and exterior of the vehicle have been developed, including layouts for seating, major equipment and construction details.
The final design is one of around 30 presented by Design Triangle. e-Traction is now using it to seek a manufacturer and ‘the UK is one of their key markets,’ says Crawshaw.
