Pop-up EV charge points trialled in Oxford

A Cheltenham company believes it has developed the world’s first pop-up EV charge point.

The solution, now being trialled in Oxford, is the result of research and development by product design company Duku and sister IP firm, Albright IP.

They believe it could go some way to tackling the EV charging issue for the third of UK car owners who don’t have off-street parking.

Andrew Aylesbury, director, Duku, said, ‘Without access to charging points the electric car revolution could bypass millions of people, particularly in the inner cities. Ironically this demographic is also one of the most likely to use an electric car, with short commutes into local towns or to train stations. If you can solve this problem, then you open up a huge market opportunity to increase the uptake of EVs in every single town and city.’

Six prototypes have now been installed during a pilot project in Oxford. The trial will take place over the next six months and users will be able to book an electric car which has been made available for the period of the pilot.

Once complete, the pilot will allow Duku to verify the reliability of the prototypes and investigate how it fared against daily use, British weather and being installed on a typical UK street. Duku will then review the findings and incorporate improvements within the next development phase which will involve a larger scale roll out as well as introducing an app-based user interface.

Alex Lee, director, Duku, said, ‘The project came with a huge number of challenges, from reducing visual ‘street clutter’ to the shallow depth available below ground. Cities such as Oxford have a lot of historical architecture and utilities under the pavement. So, minimising the depth below the ground is one of the big challenges. At the same time, it needs to rise up to a certain level to make it accessible for everyone, so we worked hard to miniaturise its components while also creating a charge point that could rise up to 800mm above ground level.’

With the IP secured and protected by sister company Albright IP, the prototypes have been developed using 3D CAD (Computer Aided Design), detailed mechanical design and a range of Rapid Prototyping techniques including 3D printing and CNC machining. 

In addition, a range of sensors to detect obstacles and monitor the performance of the charge point ensure a safe, intelligent design that eliminates the chance of the charge point coming into contact with anything such as a parked car. Safety cut offs also ensure that the charge point does not power up until it detects that a car is connected.

Once retracted into the ground, the charge points sit completely flush with the pavement, preventing any trip hazards, and are only visible by a ring of light which highlights their position and lets users know of their availability.
