Title: Susumu Ukita: Innovator in Battery Technology
Introduction
Susumu Ukita is a notable inventor based in Nagoya, Japan. He has made significant contributions to the field of battery technology, holding a total of 4 patents. His work focuses on improving the accuracy of battery charge level detection, which is crucial for the efficient operation of electric vehicles and other battery-operated devices.
Latest Patents
One of Ukita's latest patents is a battery charge level detecting device. This device estimates the charge level of a battery in the range of 20% to 80%, where the charge level does not appear in the terminal voltage. The battery ECU integrates the currents of charge and discharge to provide an accurate estimation. When the ignition key is turned on, the motor generators are activated, and the generated electric power is stored in the battery. Once the charge level is detectable, the calculation is performed based on current and voltage, allowing for precise calibration of the estimated charge level. This method ensures that the charge level can be accurately detected, even under varying conditions.
Another significant patent is the method and device for detecting the state of charge of a battery assembly. This invention addresses the variation of charged amounts among battery blocks within a battery assembly. By determining the movable range of the charged amount and detecting the current position on this scale, Ukita's method allows for effective charge and discharge control based on the state of charge.
