Toshiba’s “Charge Grid” System for EVs allows efficient charging
Introduced at Smart Grid Exhibition 2010 (June 16-18) in Tokyo, Toshiba’s “Charge Grid” system consists of a Rechargeable Li-Ion battery, Rapid Charger and Bidirectional Inverter. The system also requires Photovoltaic Panels (aka solar panels) installed on top of a building and of course assumes you have Electric Vehicle (EV). So it totally targets environmentally friendly consumers. Well, as to how the system works, to put it simply, the surplus electricity generated by the PV cells installed on the building is used to charge Li-Ion batteries which are in turn used to charge EVs through a Rapid Charger. Here the Bidirectional Inverter serves as a connector between the Power Grid and the Li-Ion batteries. And during nighttime, the electricity from the building’s power grid is used to charge the batteries.
In short, the system offers an efficient solution as it allows for the storage of surplus electricity of PVs which is otherwise wasted as currently once the power grid reaches to a certain voltage, it is not possible to supply anymore surplus electricity.
