Tokyo, May 19, 2015 --- Hitachi Automotive Systems, Ltd. today announced that the company will be supplying 5,000W/kg high output power density prismatic lithium-ion battery cells for the new model Chevrolet Malibu Hybrid to be sold by General Motors (GM) in 2016.
These prismatic lithium-ion battery cells being delivered for the 2016 new model Chevrolet Malibu Hybrid employ heat resistant separators to ensure the ionic conductivity between the positive and negative electrodes, achieving not only a high output power density of 5,000W/kg, but also a high level of safety. In addition to this, the battery's ability to maintain its high output power density in GM evaluations, even under extremely low temperatures such as the minus 30℃ cold region test, led to its adoption.
Hitachi's lithium-ion battery operations for vehicles began in 1999, leading the charge worldwide and beginning mass production of safe, high-performance, long lasting products. To date, a total of over 5 million lithium-ion batteries have been introduced into the market for commercial hybrid buses and trucks, as well as hybrid passenger cars.
The many years of supply performance for lithium-ion batteries as mass produced products, together with the accumulated production and quality management know-how garnered from feedback from the market, has led to an emphasis on high reliability and earned Hitachi a high reputation from car manufacturers both inside and outside of Japan.
In addition, last year Hitachi Automotive Systems integrated the lithium-ion battery manufacturer Hitachi Vehicle Energy's design and R&D departments, advancing lithium-ion batteries by using the electronic, control, and software technology the company possessed toward battery control system development.
Hitachi Automotive Systems will continue to contribute to the evolution of electrically driven vehicles through the strengthening of electric power train products, lithium-ion batteries, and more.
