As I've said before there are many studies and trials ongoing in the area of V2G Charging, and its impact on battery life degradation. This is a very credible trial that shows a very promising outcome, that batteries can be used to 'run' buildings and feed back to the grid, whilst not impacting negatively on car range or battery life. If we keep getting these validations it makes for a very exciting option in the emobility and decentralised energy revolutions.
The study concluded that the number of EVs parked on the campus (around 2.1% of cars, in line with the UK market share of EVs) could spare the energy to power this building. In doing so, capacity fade in participant EV batteries would be reduced by up to 9.1%, and power fade by up to 12.1% over a year. Dr Uddin said: “These findings reinforce the attractiveness of V2G technologies to automotive original equipment manufacturers; not only is V2G an effective solution for grid support – and subsequently a tidy revenue stream - but we have shown that there is a real possibility of extending the lifetime of traction batteries in tandem. “The results are also appealing to policy makers interested in grid decarbonisation.”
