well as computers and LED lighting powered by DC. The park will contribute to the development of new products and systems as a testing site for the Panasonic Group’s green technologies for energy generation, energy storage and energy efficiency. The park will also be open to customers as a showroom promoting energy solutions.

focus is on the storage of energy and management within large buildings to maximise usage and take advantage of peak and non peak energy times. Essentially the company has built a fully functioning showroom consisting of offices and manufacturing plants for rechargeable batteries.


The Kasai Green Energy Park is equipped with a variety of Sanyo green technology, including a 1MW photovoltaic system that uses HIT solar cells. This is connected to a large scale 1.5MWh lithium- ion battery system for power storage and is integrated, monitored and run by an Energy Management System (EMS) that controls the energy efficient equipment in the park. The energy usage is controlled by a Smart Energy System that optimally controls all the systems throughout the site. This can be as simple as light intensity depending on needs as well as interactive turning on and off of electrical devices as a person enters a room. The park will reduce CO2 emissions by 2,480 tons per year with the efficient energy utilization.


The Administration Building, one of facilities of the Park, features a DC Power Distribution System, as


Sanyo has developed the Battery Management System which controls the charge and discharge of electricity generated by the solar cells etc and stored into storage batteries. The Battery Management System, combines a number of standard battery systems for power storage and the Battery Management Controller can efficiently charge and discharge the energy, managing a number of batteries as though they were one battery. The battery system makes it possible to manage the very impressive power storage system that combines a total of 310,000 cylindrical lithium- ion batteries.


The li-ion facility is located on the grounds of the company’s Kasai Plant. The new factory is capable of producing up to one million battery cells per month. The output will be increased if demand is sufficient to warrant it the company has stated. Another aspect of the Park is to capitalise on increasing demand of rechargeable batteries for electric cars. The company has been supplying nickel-metal hydride (NiMH) batteries for hybrid electric vehicles (HEV) to Ford, Honda and Volkswagen, while working on a co-development of the NiMH batteries with PSA Peugeot Citroen. The front of the Park has a electric car top up solar umbrella that demonstrates the ability to maintain electrically charged vehicles.


The company intimated there are other automobile makers they are working with but declined to name them. The company hopes to achieve a 30% to 40% share of the global battery market for Green cars by 2020 and expects the battery market to grow to 1.5 trillion yen in 2020.

Only a few months after completing the battery factory in Kasai, Sanyo has already announced a 15 billion yen investment to increase its annual output capacity for automotive lithium-ion batteries by 150 percent. The plant already has 2 production line, and 2 new ones will be added to produce batteries with capacities of 20 ampere- hours or higher for use in plug-in hybrids and electric vehicles.
