The world’s first pop-up mini solar car park and electric vehicle charging hub, deployable in just 24 hours, has been revealed at the Surrey Research Park, Guildford. Developed by 3ti, a UK designer, installer, funder and operator of Solar Car Parks (SCPs), Papilio3 tackles the UK’s need to expand electric vehicle (EV) infrastructure ahead of the government ban on the sale of new diesel and petrol vehicles in 2030.
The unit is built around a recycled shipping container and can support up to 12 fast EV charge points. The solar and battery-boosted charging system optimises the speed of charge and reduces the carbon intensity of electricity used. Papilio3 is available from 3ti on a rental contract and therefore requires no capital investment by customers.
“Overnight charging at home generally provides the most cost effective, carbon efficient, sustainable form of EV charging, but in the UK, around 50% of households will not be able to do this,” said Tim Evans, 3ti founder & CEO.
“If you live in a flat, a tower block, a rented house, in temporary accommodation or even in a £10m terraced town house in Chelsea, you’re probably not going to be able to charge an EV at home.”
Papilio3 is fitted with three modular canopies that support 36 solar panels and has battery storage capacity of up to 250 kWh. It has been developed by 3ti with Cambridge Design Partners, and has been designed for roll-out at workplaces and public destinations such as hospitals, hotels, meeting venues, sports or shopping centres, tourist attractions and town centres.
Each unit offers sheltered, illuminated and secure parking, plus a convenient, available and reliable EV charging experience that supports a mixture of 7, 11 and 22 kilowatts.
“We believe that solar and battery boosted destination and workplace charging will become the best EV charging solution for drivers, irrespective of the type of home they live in,” Evans continued.
“By utilising dwell times of several hours, when cars are parked at work or when the driver is visiting a shopping or leisure venue, for example, 3ti’s system ensures that EVs can achieve a level of charge that covers day to day driving needs and does it in the most low carbon way.”
The pop-up mini solar car park and EV charging hub is deployable in just 24 hours.
Papilio3 integrates three technologies that are more usually considered individually: solar photovoltaic electricity generation, Battery Energy Storage Systems (BESS) and EV charge points. Combining the three offers a range of benefits, including the ability to use grid energy, solar power and battery storage to optimise the speed and carbon intensity of EV charging.
Onsite renewable energy generation from solar panels also reduces energy costs and gives businesses greater control over energy supply.
”Widespread adoption of SCPs will turn underutilised spaces into renewable energy generating assets, and adding batteries and EV charge points will accelerate decarbonisation of the UK’s transport sector,” said Evans.
“Allowing businesses to generate renewable energy right outside their front door not only gives them greater control of energy costs, it also makes a huge statement to customers and visitors that they are serious about tackling climate change and reducing carbon emissions.”
Long lead times caused by complex planning approvals and investment requirements were traditional barriers to SCP installations. Papilio3 units are owned by 3ti, provided on a monthly rental basis and require limited approvals, overcoming these hurdles by enabling a 24-hour deployment and installation time, and requiring no capital investment by customers.
“One of the best things about owning an EV is that you don’t have to visit a petrol station to fill up,” said 3ti Chief Technical Officer, Mark Potter. “As EV drivers, we want to charge when we stop, not stop to charge.”
