Toshiba Corporation today announced that its SciBTM rechargeable battery has been chosen by Honda Motor Company to power its new electric car, the Fit EV. Toshiba will supply battery modules for the new car, which will be launched in summer 2012 in Japan and the U.S.
The SciBTM module was developed with Honda, as the carmaker tested it in real-world situations on next-generation personal mobility products since December 2010. Honda selected the SciBTM module for the Fit Ev after undertaking an evaluation program that tested the battery’s performance under various demanding conditions.
The SciBTM battery has features that make it appropriate for automotive use, as the lithium titanate oxide in the battery anode achieves rapid charge times and a long battery life. Also, the SciBTM is capable of fast charge and stable power discharge in a wide range of conditions.
Charging time of the SciBTM is about half that of a typical Li-ion battery. A SCiB20Ah cell charged with an 80Ah current will reach 80% of capacity in 15 minutes and 95% in only an additional 3 minutes. Additionally, the SCiBTM generates little heat during fast recharging, eliminating the need for power to cool the battery module. The full charge-discharge life cycle for the SCiBTM is 4,000 times, over 2.5 times that of other Li-ion batteries.
