Title: Yosuke Ishikawa: Innovator in Battery Technology
Introduction
Yosuke Ishikawa is a prominent inventor based in Saitama, Japan. He has made significant contributions to the field of battery technology, holding a total of 13 patents. His work focuses on improving the performance and efficiency of secondary batteries, particularly in automotive applications.
Latest Patents
Ishikawa's latest patents include an information supply device and method, as well as a battery charging control system. The information supply device is designed to acquire information regarding the degree of deterioration of a secondary battery used for vehicle travel power. It features an acquirer that gathers this information, a deriver that assesses the battery's performance, and a display controller that presents this performance visually. The performance indicated is intentionally lower than the derived performance to provide a conservative estimate.
His method of charging a battery is based on calculating the ion concentration of a solid active material. The charging control system utilizes a controller that manages the charger to heat the battery at low temperatures through pulse charging and discharging until it reaches a desired temperature. Once at the appropriate temperature, the system transitions to normal charging mode. The controller also calculates the ion concentration at the battery's electrode portions based on temperature and electric current data, switching between charging and discharging modes as needed.
