Stopford’s Renewable Energy Technologist Alex Hulley is taking part in OVO Energy’s Vehicle To Grid (V2G) trial with a 40kWh Nissan Leaf. Using a bidirectional inverter / battery charger, the V2G unit allows energy to be transferred to and from the vehicle’s battery pack. When plugged in at home, the vehicle will power the Grid during periods of high demand and recharge when excess power is available. This model enables a flexible, distributed storage system that can be used in a wide range of applications, both at home and at the workplace where vehicles sit idle for hours at a time.
A commonly heard concern for the rapid expansion of Electric Vehicles, is that everybody will come home from work, plug in at the same time and overwhelm the Grid. Well, what if you could plug in and help to power the Grid instead?
Compared with a traditional “plug-and-go” charging device, intelligent management of battery charging can also be beneficial to the health of lithium-ion based cells, as the battery pack will only reach a user-specified State of Charge (SoC) when required. This is an improvement to simply charging to and holding at 100% SoC overnight, or during the working day, which is well-known to be detrimental to lithium-ion batteries – including the one in your mobile phone!
The domestic trial will run for a 2-year period, at which point ownership of the charger transfers to the resident – or is removed by OVO Energy free of charge. For more information and to register your interest, head to the link below, or contact [email protected] for his experience so far.
