“The apartment comes with batteries,” the birth
March 10th, 2010Recently, Japan’s Itochu and Itochu Urban Development Co., Ltd. started selling the apartment is equipped with a battery “CREVIA two sub-Tamagawa,” would henceforth be used in electric vehicles, lithium-ion rechargeable batteries for household batteries again, “the battery recycling business” with the specific action, is no longer a plan.
The apartment is set by the Itochu-funded U.S. EnerDel-made lithium-ion rechargeable battery as a battery. Capacity of 24kWh. In addition, the apartment roof also set the output power of 10kW of solar panels. In addition to solar power to the apartment through the public part of the daytime lighting supply of electricity, the remaining part of the power could also be temporarily stored in batteries for night-time lighting. Set in the apartment’s annual power consumption of LED lighting products, ” Inspiron 1721 battery is about 10000 kWh, solar power can be passed primarily to provide.” As a result, residents will be able to reduce about 1,200 yen per household per month management fee burden.
The Itochu major aim of these measures is the accumulation of lithium-ion rechargeable battery of the empirical data. In order to be used in battery electric vehicles for other purposes, the need to determine the correct battery status, to clarify remaining life. Because the “lithium-ion rechargeable batteries due to aging of the different use of the environment vary widely.”
Through the solar power generated electricity stored in lithium-ion rechargeable battery, PC764 , Latitude D620 battery and then used for the lighting of common parts of apartment. Itochu said that in the “CREVIA two sub-Tamagawa,” apartment, the public part of the lighting power needed for solar power generation can be passed primarily to provide.
Itochu has decided to establish the evaluation battery performance to ensure the battery quality methods as the goal, to collect the battery temperature, charge and discharge times and the amount of data such as charging and discharging. Among them, “the greatest impact on the aging factor is temperature. Would like to have this data as a reference for the development of high temperature can inhibit the rapid aging contribute to the cooling structure.”
Although the introduction of a new battery, but Itochu confident that “the attempt to carry out the battery will be in the future re-use of business start.” Although the cost of batteries and solar panels, etc. The total cost to reach the “2000 around ¥”, but it will not be passed on to apartment sales price.
