Hitachi 48V lithium-ion battery pack

Recently, Hitachi Automotive Systems has developed a 48V lithium-ion battery pack with a new output density and energy density for medium-duty hybrid vehicles. Hitachi Automotive Systems began supplying samples to automaker customers and will begin mass production in 2019.

It is understood that the output density of the battery pack is 1.25 times that of the traditional single product, and the energy density is 1.5 times that of the traditional single product. At the same time, the internal resistance of the battery cell is controlled, the heat generation is reduced, and the outer frame of the lithium ion battery pack is made of metal having high thermal conductivity and heat release property, thereby improving the installation freedom and effectively reducing the overall thickness of product. In addition, the medium-electric hybrid system equipped with a 48V lithium-ion battery has a good fuel consumption reduction effect and a high cost performance.

In the future, Hitachi Automotive Systems will continue to provide electric power transmission products including high-performance, high-reliability lithium-ion batteries to electric vehicles with huge market demand, and promote the development and popularization of electric vehicles contribution.
