Publication number: 20160121735Abstract: Embodiments of the disclosed technology are directed to a rapid charging power supply system capable of rapidly charging an electric moving body, such as a vehicle. Certain example embodiments are directed to a rapid charging power supply system capable of rapidly charging two electric moving bodies with different charging methods at the same time using a single system. For example, a rapid charging power supply system capable of rapid charging, using a single system, both an electric moving body having a rapid-charging control means equipped therein and an electric moving body that does not have a rapid-charging control means equipped therein is provided.Type: ApplicationFiled: May 13, 2014Publication date: May 5, 2016Applicant: Institute for Energy Application Technologies Co., Ltd.Inventor: Tomio Sugano

Patent number: 8183819Abstract: A boosting-charge power supply apparatus which supplies electric power for charging a mobile body having a boosting-charge control function includes: a rectifier for supplying DC power; a first power storage for storing DC power from the rectifier and outputting DC power; a charging circuit which sends DC power from the first power storage directly to a vehicle including a second power storage for storing DC power from the first power storage; and a power-supply controller for stopping the rectifier from supplying electric power to the first power storage while the first power storage is supplying electric power to charge the second power storage. Through the controller, DC power supplied from the first power storage becomes suitable for charging of the second power storage on the vehicle side, thereby enabling the same boosting-charge power supply apparatus to supply electric power and give a boosting charge to a different type of vehicle.Type: GrantFiled: February 19, 2008Date of Patent: May 22, 2012Assignee: Institute for Energy Application Technologies Co., Ltd.Inventor: Tomio Sugano
