Emergency home power from EVs

Mon, 07/23/2012 - 18:02 -- Ruth Williams

Progress is being made to develop EV batteries to be utilised to power homes during times of blackout. Following the 2011 Japanese earthquake much of the country was without electricity, EV batteries were used as a temporary in-home power supply.  Hybrid cars that feature an invertor can have the high-voltage direct current switched to a low-voltage alternating current to supply power back to a home at times of blackout. Nissan are leading the way in advancing this potential, they believe their Leaf car could power a home for up to two days, or individual appliances for far longer.
