BYD UK, through its partnership with Alexander Dennis Ltd, is supplying 28 BYD ADL Enviro 400EV double deck eBuses which, using smart technology, will provide bi-directional charging capable of feeding energy back to the power grid. The project represents a notable contribution from the bus sector towards the UK government’s commitment to deliver ‘net zero’ greenhouse gas emissions by 2050.
With its world-class battery, motor and core technology expertise, BYD has been instrumental in the project from the outset by delivering a total eBus management solution. Alongside its partners, BYD has been responsible for installing the innovative new ‘Vehicle-2-Grid’ (V2G) infrastructure, and is the first company in the commercial vehicle sector to provide high-power discharge technology as a V2G capability for electric buses.
The Bus2Grid consortium is led by energy provider SSE Enterprise in partnership with BYD UK, UK Power Networks and Leeds University. Funding for the project comes from the UK government through its delivery partner, Innovate UK. Further support comes from technology provider, Origami and Transport for London. This consortium has seen excellent cooperation between the automotive industry, the energy community and academia in bringing forth pioneering V2G technology into public transport. V2G enables stored energy on-board a BYD ADL eBus to be fed back into London’s power network. Vehicles are recharged overnight when energy demand is low, and tariffs cheaper, with electricity fed back to the grid when demand is high, thus helping to balance the network and increase efficiency.
Go-Ahead London’s 28 V2G eBuses from BYD ADL will be part of a total fleet of 120 electric vehicles at what is set to become UK’s largest electric bus garage with overnight charging capability at Northumberland Park. While current COVID-19 lockdown restrictions prevent the setting of a specific ‘switch on’ date, the Bus2Grid project is nonetheless gearing-up for operations to commence in the summer 2021.
