EV batteries to power trains

Researchers working on the TransEnergy research project are currently developing technology that will see the batteries of electric vehicles (EVs) being parked at railway stations used to power trains.

The £1.5 million research project, led by the University of Sheffield, will develop a demonstration car battery energy storage system, named the ‘Road to Rail’ system, at a train station. The system will connect a series of EV batteries to the railway’s power system when parked, to provide extra power during rush hour periods.

The study will also explore the technical problems surrounding the use of old EV batteries for line-side energy storage, and the legislative barriers, environmental implications on computers’ cars.

The move means commuters could receive free parking in return for allowing the EVs to be used as back-up batteries, providing Road to Rail energy exchange.

Dr Martin Foster, from the University of Sheffield’s Department of Electronic and Electrical Engineering, said: "Electric powered rail travel has helped to reduce pollution and improve the comfort of travellers. Our project will look at how we can meet the demand for more electricity on our railways by investigating innovative ways to store surplus energy.

“Similar energy storage systems are already being used on the electricity grid during peak times and by translating these to our railways could deliver real benefits to both rail companies and consumers, bringing down the costs of travel and improving services.”

James Ambrose, principal engineer for Network Rail, said: “Network Rail is committed to electrifying more lines in the UK. Our project will be working with rail providers to recommend new approaches that will mean increased efficiency for the industry.”
