Restraint of Performance Decrease of Ni-MH Battery Performance under Low Temperature by Combined Use of Heat Insulation Material and Heater

At Syowa Station in Antarctica, it is considered to utilize for renewable energy such as photovoltaic power generation and wind power generation to reduce the volume of fuel transported from Japan. However, since the renewable energy has intense power variation, it is possible that a frequency variation occurs when such systems connect to the small-scale electric system of the Showa Base. Our study is the application of Ni-MH battery under low temperature to restrain the frequency variation. In this paper, the basic test result is described.
