Thiruvananthapuram, Oct. 12 -- Electric vehicle (EV) batteries could help power homes and supply electricity to the grid, with IIT Bombay testing the technology and Keralam planning a pilot project involving more than 100 EVs.

IIT Bombay's Grid Integration Lab conducted experiments over three years on the use of EV batteries for household electricity supply.

In one trial, a car was charged using solar power during the day and supplied electricity to a professor's home at night, reducing the household's electricity bill by around 30 per cent.

The technology, known as Vehicle-to-Home (V2H), allows EV batteries to supply power to homes, while Vehicle-to-Grid (V2G) enables electricity to be fed back into the grid.
