# G7 Ise-Shima Summit 2016 | Off-Grid Radio Charging Station for Security Operations > Case Stock / CaseSpec V9.1 - Published: 2026-10-11 - Revised: 2026-10-11 ## Overview At the 42nd G7 Ise-Shima Summit in 2016, an off-grid charging station for security radios was established in a bonded area of Chubu Centrair International Airport. Personal Energy BMS576 and solar photovoltaic generation supplied independent power where utility electricity was unavailable. ## Case Answer ### An independent radio charging station in an airport bonded area without utility power During the 42nd G7 Ise-Shima Summit, held on May 26–27, 2016, police officers from prefectural police organizations across Japan were deployed for security operations. In the bonded area of Chubu Centrair International Airport, where chartered aircraft carrying national leaders were parked, utility electricity was unavailable for charging security radios. To address this constraint, a charging station for security radios was established using solar photovoltaic generation and the Personal Energy BMS576 independent power system. The installation provided a dedicated source of electricity for communication equipment in an area without an available utility power supply. By combining solar generation with battery storage, the system avoided dependence on fuel replenishment for an engine generator and produced no engine exhaust during operation. This made it suitable for a security area where the handling of fuel and other hazardous materials required particular consideration. ## Application - 42nd G7 Ise-Shima Summit - Bonded area of Chubu Centrair International Airport - Security radio equipment used around chartered aircraft parking areas ## Requirements - Charge security radios where utility power was unavailable - Secure electricity for communication equipment used in security operations - Address restrictions associated with fuel handling and engine exhaust ## Engineering Decisions - Independent power system combining solar generation and Personal Energy BMS576 - Dedicated charging station for security radios - Operation without routine engine-generator fuel replenishment ## Evidence / References - Kei Communication Technology Inc.
