A team of students have built a solar powered electric car that can travel from London to the Scottish Highlands on the same power it takes to boil a kettle.
Cambridge University Eco Racing (CUER) have just returned from their first international race with Helia – an epic 1,864-mile drive from Darwin to Adelaide as part of the Bridgestone World Solar Challenge.
The cutting edge vehicle pushes the boundaries of automotive battery technology, efficient tyres and aerodynamics, weighing only 550kg (1,200lb) due to a specialist ultra-lightweight carbon-fibre chassis and body panels tooled by Portsmouth based Formaplex, a leading lightweight manufacturer for some of the world’s biggest Formula 1 teams and automotive companies producing multi million pound high-powered supercars.
Use of composites allowed the team to drastically reduce weight while maintaining structural integrity, allowing Helia to travel further and faster than would be possible with other materials.
Helia’s streamlined aerodynamic design and lightweight construction significantly enhance the overall energy efficiency, using power from high performance lithium-ion battery packs produced in collaboration with Silverstone-based Danecca.
The battery pack has much higher energy density than most production vehicles, which gives Helia more than double the range of a Tesla Model 3, while being a quarter of the size.
Bridgestone, the world’s largest tyre and rubber company, also worked with the team to develop low rolling-resistance tyres.
Unfortunately, some early electrical issues prevented the team from progressing beyond the first stage of the gruelling race, but the only British team in its category was placed third out of 13 by the judges in the practicality category, where Helia was marked against criteria including design, versatility and desirability.
Only arriving back in the UK in the last week, they are now looking ahead to other potential solar races in Europe and beyond, while considering some potential modifications to their vehicle.
Xiaofan Zhang, CUER’s programme director, said: “While the Bridgestone World Solar Challenge didn’t go exactly as we had hoped, it is still a tremendous achievement when you look back at the progress we have made over two years. The conditions this year were particularly challenging and this is the first time this model has competed.
“Nevertheless, Helia’s performance numbers showed her to be very competitive; it bodes extremely well for future events.” He said working with Formaplex, Bridgestone and Danecca helped the team share expertise and improve efficiency of the vehicle.
“Many of our partners are world leaders in automotive engineering, R&D and high value manufacturing but are not necessarily household names,” he added. “The UK has an abundance of this expertise and we have been very fortunate to leverage their capabilities in Helia.
“Helia was designed to demonstrate technology behind electric vehicles and renewable energy and will visit schools next summer with the aim of inspiring the next generation of engineers. We have plenty of positives to take forward and are already in search of our next challenge.”
