GS Yuasa Corporation (Tokyo Stock Exchange: 6674; “GS Yuasa”) today announced that GS Yuasa International Ltd. (“GS Yuasa International”) is to commence sales of DATAWINDOW-S, a storage battery monitoring system.
The DATAWINDOW-S system automatically measures on a regular basis the voltage, internal resistance, and temperature of industrial valve-regulated lead-acid batteries used as backup electricity sources at infrastructural facilities, etc. to detect signs of abnormality and end-of-life indications early on to facilitate preventive maintenance of storage battery systems.
GS Yuasa storage battery systems are used in a wide range of sites as backup electricity sources, including at infrastructural facilities requiring high levels of reliability such as power plants, transformer stations, railway facilities, and communication base stations. They are also used as backup systems for office buildings as well as emergency lighting, security cameras, and so on.
Use of the DATAWINDOW-S system to monitor these storage battery systems will help to ensure the soundness of storage battery systems through constant monitoring, facilitate swift maintenance response through remote monitoring, and also reduce maintenance workloads. In addition, utilization of data recorded by the DATAWINDOW-S system will support the drafting of optimal update plans.
GS Yuasa International will continue to enhance the reliability and functions of storage battery systems and enhance its product lineup to protect important equipment and data from power outages due to disasters, etc. At the same time, the company will strive to deliver safety and security to customers and contribute to the realization of a safer and more secure society not only through its Mono Zukuri (product creation) activities but also through working to enhance and expand the range of the Koto Zukuri (service creation) services it provides.
