Keynote 5: Long-Term Operability of the Primary and Secondary Battery under Micro-Gravity Conditions -Lessons Learned from the In-Orbit Operation of the Spacecraft- Yoshitsugu Sone (Japan Space Agency (JAXA), Japan) Summary: In order to operate the spacecraft, the reliable energy storage devices are essential. The lithium-ion secondary battery was first used for the intreplanetary spacecraft, Hayabusa. The battery cells maintained a constant performance over 2.7 years of operation as Hayabusa travelled to the asteroid Itokawa. To maintain cell conditions, the state of charge was fixed using a balance circuit. The cell voltages differed by less than 60 mV during the operation, which is within the error expected based on the circuit design and the telemetry conditions. The off-the-shelf type of lithium-ion cells was used as the main bus battery for Reimei satellite which was injected to the Earth orbit. Two batteries consisted of 7 cell connected in series are used for the battery. A quite stable charge and discharge performance are still monitored even after 7 years’ operation in space. The lithium primary cells were used for the re-entry capsule of Hayabusa. The cells performed appropriately for the re-entry of the spacecraft into the Earth atmosphere evey after the 12 year’ storage including 7 years’ spaceflight. These experiences proved the operability of lithium type energy storage devices for long-term missions in space.

Keynote 8: Flexible, Reliable, and Fault-Tolerant Battery Energy Storage Systems for Grid Connections Hirofumi Akagi (IEEE Fellow, Tokyo Institute of Technology, Japan) Summary: Environmental concerns including carbon dioxide emission and continuous depletion of fossil fuel reserves have spurred significant interest in renewable energy. However, renewable energy sources such as wind turbine generators and photovoltaic cells are intermittent in nature under the influence of meteorological fluctuations. Interconnecting these intermittent renewable energy sources to the utility grid at a large scale may affect the voltage and frequency control of the grid. This talk pays attention to a flexible, reliable, and fault-tolerant grid-level battery energy storage system for application to massive renewable energy sources. This storage system is characterized by the combination of the leading-edge power electronics technology with the latest battery technology. The speaker presents the necessary control strategy and tactics of for a multilevel cascade PWM (pulse-width modulation) converter to be used as a power conversion circuit between the utility grid and multiple floating isolated battery units. He also verifies the validity and effectiveness of this battery energy storage system, showing experimental waveforms obtained from the 200-V, 10-kW, 3.6-kWh prototype combining the three-phase, seven-level cascade PWM converter with nine nickel-metal-hydride (NiMH) battery units.
