Publication number: 20090153104Abstract: A charging method includes first and second charging steps to charge a lithium-ion battery. In the first charging step, a temperature rise gradient of the battery to a current is detected. A battery temperature when the battery is charged to a first predetermined capacity is predicted based on the gradient. A charging current is controlled based on the predicted temperature. The battery is charged, at a current that brings a battery temperature lower than a predetermined temperature, to the first predetermined capacity. In the second charging step, a temperature rise gradient of the battery is detected. A battery temperature when the battery is charged to a second predetermined capacity is predicted based on the gradient. A charging current is controlled based on the predicted temperature. The battery is charged, at a current that brings the temperature of the battery lower than the predetermined temperature, to the second predetermined capacity.Type: ApplicationFiled: December 11, 2008Publication date: June 18, 2009Inventors: Shinichi Matsuura, Atsushi Kawasumi

Patent number: 7301444Abstract: A method for alarming decrease in tire air-pressure, which detects decrease in internal pressure of a tire attached to a vehicle and accordingly issues alarm. The method includes the steps of: detecting rotational information of the respective tires; storing the rotational information of the respective tires; displaying a summer tire, a winter tire and a run-flat tire; designating a currently attached tire from among the displayed tires and switching to a threshold for judging decrease in internal pressure which matches the tire; judging decrease in internal pressure of a tire by using the threshold; and issuing an alarm on the basis of the judgment of the judging means. Since thresholds which match tires can be suitably switched when the driver operates the touch panel for discriminating presently mounted tires, it is possible to eliminate erroneous alarm and to perform judgment of decompression at even higher accuracy.Type: GrantFiled: September 9, 2003Date of Patent: November 27, 2007Assignee: Sumitomo Rubber Industries, Ltd.Inventor: Shinichi Matsuura

Patent number: 7213453Abstract: A method of judging a vehicle loading condition includes detecting rotational speeds of wheels mounted on a vehicle, calculating a judging value of tire pressures based on the difference of the sum of rotational speeds of two pairs of wheels located at the opposing corners of the vehicle and detecting an acceleration to a lateral direction of the vehicle. The loading state of the vehicle is judged by the change of a primary coefficient based on an approximated relation between the acceleration to a lateral direction and the judging value of the tire pressures. A tire deflation warning system detects the stop of the vehicle, and the air pressure of four wheels is judged not to be decreased if the loading condition of a vehicle is changed more than a fixed value before and after a vehicle stop. The tire deflation warning system can prevent a deflation alarm for a vehicle with a heavy load.Type: GrantFiled: July 20, 2005Date of Patent: May 8, 2007Assignee: Sumitomo Rubber Industries, Ltd.Inventor: Shinichi Matsuura
