Abstract: 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.

Abstract: 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 is detected. A battery temperature when the battery is charged to a first predetermined capacity is predicted based on the detected gradient. A charging current is controlled based on the predicted temperature. The battery is charged, at a current that results in a battery temperature that is 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 results in a temperature of the battery that is lower than the predetermined temperature, to the second predetermined capacity.

Abstract: Application of rechargeable battery charging voltage is determined by a signal applied to a battery-connect terminal (94) from external electrical equipment. In the case of a charging voltage application, the current detection section is judged as malfunctioning when the maximum battery cell voltage detected as a time series rises from a voltage below 3.8V (the second voltage) to a voltage above 4.1V (the first voltage) even though rechargeable battery charging and discharging current detected as a time series is greater than −5 mA and less than 20 mA.
