UK startup develops unique EV design that could boost range
UK startup Page-Roberts has revealed an innovative design concept for electric vehicles, that they claim can boost range by up to 30 per cent.
Most electric vehicles on the market today utilise a ‘skateboard’ structure, placing the batteries under the floor of the vehicle. However, Page-Roberts has patented a design whereby the battery packs are mounted vertically inside the cabin itself, between two rows of opposite-facing seats.
The company claims that this pyramid style structure offers a more compact solution, allowing the car to sit lower, be more aerodynamically efficient, and weigh less. Allegedly, the design offers savings up to 75kg compared to the skateboard design.
Manufacturing costs are also said to be slashed by up to 36 per cent, and the range could be extended by up to 30 per cent due to increased efficiency.
“The skateboard arrangement has become the mainstay of most EVs. But this results in taller vehicles with increased aerodynamic losses and energy consumption (especially at motorway speeds), extra structure required to protect against impact, and a longer wheelbase to account for the battery. The increased size and weight inhibit range. By simply moving the location of the battery pack, we have come up with a much more efficient solution,” said Freddy Page-Roberts, Chief Executive Officer of Page-Roberts.
The design is envisaged as a solution for small electric vehicles, particularly “sleek and sporty four-seat vehicles,” which would benefit from a shorter wheelbase and lower height design. However, the firm already has plans in place for a range of vehicle types, including multi-purpose seven-seaters for the family.
Page-Roberts Chief Technology Officer Mark Simon, outlined the motivation for the design, saying “challenges around battery cost and energy density along with range and charging infrastructure continues to stall progress with EVs, despite both car brands and tech leaders racing to put their stamp on the market.”
“Our design concept reduces cost, increases efficiency, enhances agility, and offers design freedom. The efficiency translates to less time charging from either longer range or smaller batteries, so pressure on charging points – another key pain point for the industry – will also be reduced.”
