Development of Electric Drive System to be used in Electric Scooters
Sanyo Electric Co., Ltd. and Suzuki Motor Corporation have co-developed Electric Drive System featuring a high performance in-wheel motor in addition to high efficiency control circuit which was developed by Sanyo. In addition to this Sanyo developed a dedicated charger and a battery system for the electric motors using Sanyo’s Li-Ion batteries which company developed for consumer equipment. Read more
Development of Li-ion Batteries for Plug-in Hybrid Electric Vehicles by HITACHI
On expanding the battery system business with an aim toward its industrial applications, Hitachi and Hitachi Vehicle Energy Ltd made an announcement on development of lithium-ion batteries for plug-in hybrid electric vehicles. The plug-in hybrid electric vehicles (PHEVs) have two running modes, namely an EV (Electric Vehicle) mode where the vehicle runs solely on a motor and an HEV (Hybrid Electric Vehicle) mode where the vehicle is operated by both the engine and the motor offering a dramatic improvement on gas mileage and reduction on exhaust emission.

Development of new Li-air Battery for Electric car application
Electric vehicles have been already commercialized to a certain extent but in order to promote its wider use the current energy density powering these vehicles needs to be improved by six to seven folds. One alternative would be the use of Li-ion batteries which are widely used in mobile phones and Laptops but Li-ion batteries’ energy density are too low for its use in electric vehicle application. Even with performance improvement and cost reduction for Li-ion batteries in order to achieve an uninterrupted long distance driving a great number of such batteries need to be mounted on the vehicle resulting in significant increase in vehicle cost. The other promising alternative at least in a theoretical sense is Li-air batteries offering a much higher energy density than Li-ion batteries. Read more
