In the past, Electrovaya has partnered with Tata Motors and Miljø Grenland/Innovasjon to manufacture batteries and electric cars using Electrovaya’s Lithium Ion SuperPolymer battery technology.[4] The Tata Indica EV was scheduled to be launched in Norway in 2009 and India in 2010. It was purported that Electrovaya’s batteries could deliver 120 of range.[citation needed]


The first all-electric car-sharing program in the U.S. debuted at Baltimore's Inner Harbor with Electrovaya offering its Maya-300 for rent at the Maryland Science Center. The car could go up to 120 miles (190 km) on one charge of its lithium-ion battery system.[5]
